3 I. Introduction C. E. Raines Company has been authorized by the City of Flat Rock (City) to assist in the development of the city s road asset management strategy. The City owns and maintains approximately 31 miles of roadway. Approximately 25 miles are concrete, 2.22 miles are asphalt and 3.71 are gravel. Approximately nine miles of City roads are classified as major and are classified as local. This analysis considers local and the major that are paved for a total centerline mileage of and excludes major and local gravel roads representing 3.71 center line miles. The Pavement Surface Evaluation and Rating (PASER) system is used to evaluate the condition of road segments. The PASER system rates each segment on a scale of 1-10 with 1 being the worst condition, and 10 being the best condition (new pavement). The ratings directly correspond to the expected remaining service life as well as appropriate maintenance activities. The Grand Valley Metro Council (GVMC) located in Grand Rapids was contracted to collect the data for the PASER Study. The GVMC owns a van that is equipped to survey the road network. This vehicle is equipped with subsystems that can collect digital images of the pavement surface, digital images of the front view of the roadway and the right-of-way, rut depths using a five laser system, and longitudinal profile along the wheel paths. The vehicle is equipped with a Distance Measuring Instrument (DMI) and a GPS to track the vehicle position. The DMI and GPS data are integrated with images and other data. Figure 1 is a photo of the van used to collect road condition data. Figure 1. Grand Valley Metro Council Data Collection Van 1

4 Once the data is collected, it is transferred to a software program called Roadsoft. The software is a computerized roadway management system for collecting, storing, and analyzing data associated with transportation assets. Roadsoft was developed and is supported by the Technology Development Group, which is a part of the Michigan Tech Transportation Institute at Michigan Technological University. The software is provided free to cities and counties in Michigan. Roadsoft can manage a variety of data associated with transportation systems. Specific types of data include: roads, signs, culverts, guardrails, pavement markings, traffic counts, and vehicle crashes. The condition of the pavement surface, as represented by a PASER rating can be stored in Roadsoft. In addition, Roadsoft has asset management analysis tools that provide a means for creating and implementing efficient and effective construction and maintenance strategies to maximize the return of the transportation investment. Roadsoft can generate a variety of detailed reports that provide a summary of the specific data in the database. The current average PASER rating in the city is 5.9 (Good). The City allocated $200,000 of funding in the Budget for pavement maintenance and repairs. The funding allocation does not include utility funds or other matching funds such as Federal Aid Surface Transportation Program, or Community Development Block Grant Funds. Using Roadsoft, a model was prepared to evaluate the impact of different investment levels on the overall network condition over a ten year period. The model will assist the city to determine an adequate amount of funding to keep the road network from deteriorating. It also recommends which types of maintenance treatment (i.e., joint sealing, remove and replace concrete sections, etc.) to be used and a proposed funding level per year. The study concludes with a recommendation of the necessary funding levels and future steps to begin the implementation of an asset management plan. 2

5 II. Network Characteristics The City of Flat Rock currently has approximately 31 miles of roadway under its jurisdiction. The road network distribution for classification, condition, and surface type are summarized below.

6 III. Distress Types The PASER rating system is separated into categories based on concrete and asphalt pavement types, which have different distress that are specific to each pavement. The key to a useful evaluation is identifying different types of pavement distress and linking them to a cause. Understanding the cause for current conditions is extremely important when selecting the appropriate PASER rating, and associated maintenance or rehabilitation technique (e.g. load or age induced failures). For example, a street with failures indicative of extensive base failure, such as alligator cracking and rutting, would be a PASER 4 or below, because the only activities appropriate to address the cause of the failure would be heavy rehabilitation or reconstruction. There are four major categories of common concrete and common asphalt distresses as shown below. 1. CONCRETE SURFACE DISTRESS a. Surface Defects: Wearing and Polishing, Map Cracking, Pop-outs, Scaling, Shallow Reinforcing, and Spalling. b. Joint Failure: Longitudinal and Transverse c. Pavement Cracks: Transverse Slab Crack, D-Cracking, Corner Cracking and Meander Cracking d. Pavement Deformation: Blow-ups, Faulting, Pavement Settlement or Heave, Utility Repairs, Patches and Potholes, Manhole and Inlet Cracking, and Curb or Shoulder Deformation 2. ASPHALT SURFACE DISTRESS a. Surface Defects: Raveling, Flushing, and Polishing b. Surface Deformation: Rutting, Distortion (including Rippling and Shoving, Settling, and Frost Heave) c. Cracks: Transverse, Reflection, Slippage, Longitudinal, Block, and Alligator cracks d. Patches and Potholes Examples of City streets for concrete surface distress and PASER rating are provided in Appendix A. 4

7 IV. Maintenance and Repair Alternatives There are three categories of maintenance/repairs available for maintaining roadway infrastructure: Preventative Maintenance, Road Rehabilitation and Road Reconstruction. A brief overview of each category is followed by a more detailed description of the individual alternatives and their costs. CATEGORIES Preventative Maintenance Preventative Maintenance (PM) is appropriate for newer roads in Very Good (8) to Good (6) condition. PM lengthens the service life of a structurally sound pavement. PM is limited to surface improvements such as crack seals, and joint seals and surface seals. Road Rehabilitation Road Rehabilitation (RH) procedures are appropriate for roads in Fair (4-5) condition. More intense rehabilitation procedure can be appropriate for roads rates in Poor (3) condition. RH may include localized full depth removal and replacement, mill and overlay, or other methods to improve the base and/or cross section of the pavement such as pulverize, re-grade, and overlay. RH procedures are more intensive than PM, but can restore a pavement to excellent condition at a significantly lower cost than full Road Reconstruction. Road Reconstruction Road Reconstruction (RC) procedures are appropriate for roads in Very Poor (2) to Failed (1) conditions. A rating of 1 or 2 means the road has no more useful service life. In this case full reconstruction with extensive base repair is necessary. Often, other types of work need to be considered with full reconstruction, such as drainage improvements or water main or sanitary sewer replacement. Alternatives The following text details possible maintenance and repair alternatives along with costs associated with each improvement. Note that the costs are based on fair market prices bid for similar jobs, including miscellaneous items such as traffic control and restoration. The following costs are typical average total project costs. They include typical engineering costs, such as design, inspection, and materials testing. The costs will need to be evaluated each year and updated to reflect current market conditions. The category of the improvements is indicated next to each repair alternative in parentheses. 5

8 Concrete Maintenance Program Crack/Joint Sealing (PM) Description: This process involves cleaning and routing cracks and/or joints and then filing them with hot rubber sealing compound. Sealing the cracks and/or joints inhibits water from penetrating the cracks, freezing expanding and causing the pavement to fail. Cost: An estimate of cost for this alternative is $1.25 per square yard of roadway to be maintained, but will vary with the severity of cracking and joint spacing. Joint Sealant Being Applied Joint Seal with Corner Break Repair (PM) Description: This process involves removing limited sections of the pavement to full depth, typical corners of slabs, and then resealing the joints surrounding the repair. Cost: An estimate of cost for this alternative is $35.00 per square yard of roadway to be maintained, but will vary with the severity of cracking and joint spacing. 6

9 Full Depth Slab Replacement (RH) Description: This process involves the full reconstruction of the failed concrete slabs and resealing surrounding joints. Cost: The estimated cost for this alternative depends on the percentage of the total roadway area that needs repair. The cost is approximately $45.00 per square yard if 25% of the road surface area requires repair and the same price per square yard if 50% of the road surface requires repairs. If slab replacements exceed 50% of the road surface, reconstruction should be considered. Note the square yard costs provided are for total project based on the anticipated percentage needing repair.

10 Full Re-construction Concrete Pavement Concrete Pavement Road Reconstruction City Local (RC) Description: The reconstruction of local concrete streets involves the removal of the existing concrete pavement and base and includes the construction of a new concrete paving section consisting of 8 of concrete placed on a 6 aggregate base. Cost: An estimate of cost for this alternative is $75.00 per square yard of road way to be replaced. Concrete Pavement Road Reconstruction City Major (RC) Description: The reconstruction of a major concrete street involves the removal of the existing concrete pavement and base and includes the construction of new concrete paving section consisting of 10 concrete placed on an 8 aggregate base. Cost: An estimate of cost for this alternative is $95.00 per square yard of roadway to be replaced. Concrete road pavement ongoing. 8

11 Asphalt Maintenance Program Overband Crack Seal (PM) Description: This process involves cleaning and applying an overbanding material. Overband crack seal material is comprised of rubber and tar with polyester fibers. Compressed air is used to clean each crack and its surrounding area prior to application of the material. The material is poured into cracks and onto the surrounding area creating a strip of overbanding material approximately 4-5 inches in width. Routing is not necessary to apply material. This alternative can be used on asphalt roadways with cracks up to 3 deep. Cost: The estimated cost for this maintenance alternative is $1.00 per square yard of pavement, but will vary with the severity of cracking. Application of Overband Crack Seal Crack Route and Fill (PM) Description: This process involves using a mechanical device to rout each crack in order to widen, cut, and clean the cracks prior to filling with bituminous materials. The bituminous materials fill the entire volume of the crack providing structural integrity to the pavement while also preventing moisture from entering the pavement structure. Cost: Crack route and Fill is approximately $1.25 per square yard. Crack Routing Crack Sealing 9

12 Mill and Overlay, 1.5 and 3 (RH) Description: Milling is a process by which the top section of pavement is milled off and discarded. This results in a rough surface to which an additional layer of pavement or emulsified asphalt surface treatment can be applied. A mill and overlay operation typically has two different mill depths, 1.5 and 3, depending on the road condition and existing roadway depth. For a roadway cross sections with less than 6 of pavement with minor surface defects or deformation, 1.5 milling is the preferred solution. For pavement cross sections with 6 or more pavement, and where there is more substantial surface defects exists, a 3 milling is more appropriate. The 3 milling depth allows for the removal of more substantial surface defects and rutting while also allowing for the placement of additional HMA material Cost: An estimate of cost for milling full width and placing 1.5 overlay is approximately $22.00 per square yard. A 3 mill and overlay costs approximately $27.00 per square yard. Milled asphalt pavement Asphalt paving after milling 10

13 V. Maintenance Alternatives C.E. Raines Co. met with the Director of Public Services to determine which maintenance procedures the city wanted to include in the analysis. The following table identifies the alternatives considered PASER Trigger and reset values, and costs. MAINTENANCE ALTERNATIVES PASER Rating Concrete Pavements Trigger Cost Cat.

14 VI. Roadsoft Modeling The Roadsoft software utilizes a model of the entire road network as defined by the user. It is populated with features of each road segment, such as length width, and condition. The software applies user-entered parameters such as maintenance cost and total project budget to select a mix of maintenance procedures that will optimize the overall health of the network. The model results need to be adjusted to account for constraints or conditions that are not reflected in the model. In other words, actual project selections are made based on a variety of factors, such as availability of matching funds or grant funds, which may not follow the idealized model. Other capital improvements such as intersection reconstruction, and water or sewer utility upgrades must also be considered when selecting specific segment for a particular treatment. Roadsoft requires the following inputs and parameters in order to perform an analysis: Overall Road Network Segment Length Segment Width Segment PASER Condition Deterioration Rates (Curves) Candidate Maintenance Procedures Candidate Maintenance Costs Maximum Program Budget Inflation Rates Program Duration (e.g. 5 years, 10 years, etc.) The overall road network defined for this analysis includes asphalt and concrete city roads. The road length and width are static parameters that define each road segment in the network. The PASER condition is assigned during the field inspection and then adjusted by the software to account for deterioration, or improvements related to maintenance activities entered into the program. The maintenance procedures, costs, budget, inflation rates and program duration are all user defined inputs that are customized based on community budgeting needs. The deterioration curves are used by the model to predict future conditions. A unique curve is defined for concrete and asphalt roads. The remaining service life (RSL) of the road is defined as the years after initial construction before the road segment drops from a 4 to a 3 PASER rating. In other words, it is the window in which maintenance and light rehabilitation projects are cost effective procedures. Once a road drops to poor condition (PASER 3), major rehabilitation or total reconstruction are the only cost effective alternatives. The key to a successful asset management plan is applying the most cost effective procedure at the proper time. This means allocating resources to preserve the portion of the network in good to fair condition before pursuing the heavy rehabilitation and reconstruction projects. The deterioration 12

17 For this analysis, a 28 year service life was used for concrete roads, and an 18 year service life was used for the asphalt roads. The service life can be extended beyond the initial values with preventative maintenance and rehabilitation processes as described above. The service life for a road can vary greatly based on subsurface conditions, mix design and other factors. The deterioration curves used in the model represent the average behavior The pavements optimization module in Roadsoft uses the input parameters to return the following results: Remaining Service Life (RSL) Years until the segment is expected to drop from PASER rating 4 to PASER 3, at which time maintenance procedures are no longer cost effective Projected average PASER rating of the network each year modeled Miles of road to receive specific treatments each year Funding allocation per treatment per year Total budget per year Roadsoft does not select specific segments to receive treatment. The next step in developing a program includes using the model output as guidance in selecting specific streets and subdivisions for treatment. As the road program progresses, treatments and new field ratings should be entered into Roadsoft to track the accuracy of the previous projections and improve future model accuracy. 15

18 VII. Analysis and Results The local and major streets in the City of Flat Rock street system were evaluated on a network level basis. This means the analysis sought to select a mix of fixes that would have greatest overall impact on the average network condition. Several iterations were performed for various funding levels and program durations. The analysis was narrowed to the five scenarios discussed below. It is important to look at the impact of a particular levels of investment on the remaining service life of the system Chart 3 illustrates the projected Remaining Service Life (RSL) at various funding levels. The RSL can be even an even more accurate representation of the health of the network than the PASER rating. While a road may have the same PASER rating for several years, each year of age is represented by one RSL. Chart 3 Average Remaining Service Life Comparison 16

19 Investment per Year for 10 years Remaining Service Life, Year 1 Remaining Service Life, Year 10 Do Nothing $200, $600, $1 million $1.25 million Table 5. Comparing Investment level to RSL The City currently has $200, budgeted for local and major street repairs. By examining the Remaining Service Life chart and table at the current rate of the investment the RSL drops significantly to years. This means that in 2024 the city road network will be 5 years beyond any type of preventive maintenance or rehabilitation to increase the RSL. Thus, in order to raise, the remaining service, half the roads will have to be reconstructed. A $600,000 investment for ten years will lead to a decrease in RSL, but not as significant as a $200,000 investment. Even with a $1 million per year expenditure the remaining service life will stay positive, however, will have a downward trend. With an annual investment of $1.25 million for ten years the RSL will reach a level of 4.80, which is higher than the current year s average of

20 VIII. Conclusions and Next Steps The next steps in the process are identifying the investment level that will be dedicated to the road program and selecting neighborhoods and road segments for the various treatments. The analysis shows that the current level of $200,000 per year is not sufficient to maintain the health of the system. Therefore a funding level of $1.25 million should be established to maintain and improve the health of the road network, thus preventing the necessity of reconstructing half of the City s paved roads by Once an investment level is determined, we recommend preparing a five year maintenance plan as follows: Within the first three years, identify road segments to receive preventative maintenance in the form of joint sealing, slab replacement, and rehabilitation. Reassess and identify, for the fourth and fifth, year a general strategy to raise the service level. The strategy may include increasing re-construction or slab replacement with additional preventative maintenance. The goal is to avoid falling behind up keeping the desired level of service. Roadsoft should be used to track all capital and maintenance work. We also recommend that a condition rating for the entire system be collected once every three years, to establish a good data set for the network. Maintaining a complete database of yearly ratings and maintenance procedures which will allow the model to be further refined and provide more accurate projections into the future. The program should be reviewed on an annual basis, and be adjusted as necessary to meet the City s goals. Next Steps Determine a level investment for the road network Develop a five year maintenance plan Track all maintenance and capital work with Roadsoft After 3 years collect new PASER data Refine model with new PASER data and maintenance data Refine and adjust program annually to meet City s goals 18
