3 South African Road Network Authority Paved Gravel Total SANRAL 18, ,247 Provinces , , ,739 Metros ,682 14,461 66,143 Municipalities 37, , ,849 Total 153, , ,978 Un-Proclaimed (Estimate) 140, ,000 Estimated Total 153, , ,978 Un-Proclaimed Roads = Public roads not formally gazetted by any Authority

4 South Africa has the 10 th Longest Total and 18 th Longest Paved Road Network in the World Roads Represents one of the largest public infrastructure investments in most countries RSA Road Replacement Cost >R2 Trillion

5 Houghton Sunninghill Eish!!! How Did This Happen?

6 Road Condition Why is it Happening Pavement Design? Road Deterioration due to Traffic Loading & Environment Maintenance Actions Good Fair Poor Moisture Ingress 20 Very Poor Year No Maintenance (Typically Designed for Traffic Expected over Years) SA Pavement Design Requires Performance of Preventative Maintenance

7 Why is it Happening Pavement Design? Increased Number of Heavy Axles Repetitions over year Design Life South Africa Waterproof Layer Northern Hemisphere (10 to 40 mm) (100 to 400 mm) Local Street Farm To Market Typical National / Interstate Road 7

8 National Road Network Length (Carriageway km) Why is it Happening Pavement Age 100% Pavement Age Trend 90% 80% 70% 60% 50% 40% 30% 20% 10% 0% Year >25 yrs yrs yrs yrs 6-10 yrs 0-5 yrs Please Note: 75% of Network Older than Original 20 Year Design Life 8

9 Why is it Happening Axle Loads Increased Axle Load Decreasing Layer Strength Damage Located in Weaker Layers Deeper Down in the Pavement Structure

10 Why is it Happening Tire Pressure Increased Tire Pressure New Tire Technology Increased Tire Pressure Damage Located in Surface Layers Decreasing Layer Strength

11 Where is it Happening Rainfall Zones FRANCISTOWN CHIPINGE BEIRA WINDHOEK MESSINA WALVISBAY GABORONE TZANEEN KEETMANSHOOP ZEERUST PRETORIA JOHANNESBURG KLERKSDORP VOLKSRUST MAPUTO BLOEMFONTEIN LADYSMITH WEPENER ROUXVILLE DURBAN PORT SHEPSTONE CAPE TOWN CERES OUDTSHOORN SOMERSET WEST MOSSEL BAY PORT ELIZABETH EAST LONDON Wet (>1000 mm/yr) Moderate ( ) Dry (< 500 mm/yr)

12 Road Condition What Is The Price We Pay Government Good Repair Cost = X / km Repair Cost = 6X / km (Ratio 1:6) Fair Poor 3-5 Years Repair Cost = 18X / km (Ratio 1:18) 20 0 Very Poor 5-8 Years Year Please Note: Typical Costs for 11.4m Wide Road in Flat Terrain

13 Road User Cost (R/km) What Is The Price We Pay Road User R 20 Good Condition Poor Condition Very Poor Condition R 18 R 16 R 14 R 12 R 10 R 8 Toll Class 1 Toll Class 2 Toll Class 3 Toll Class 4 R 6 R 4 R 2 R 0 Good International Roughness Index (m/km) Poor Based on HDM-4 Modeling

14 Typical Life Cycle of a Road in South Africa? New Road - Deterioration over time due to Traffic Loading & Environment NO Preventative Maintenance - Crack Sealing - Cleaning Drainage Structures - Cutting of Grass

15 What Is The Solution Automatic Pothole Patching? Nooooooo. Potholes are the symptom not the cause If we strive to become best pothole repairers in the world.. Then we have lost the plot...

16 What Is The Solution Preventative Maintenance! SANRAL Routine Maintenance Cost - Crack Sealing, Cleaning Drainage Structures, Cutting of Grass - R 6.50 m 2 / year SANRAL Reseal Cost - R70 R130 m 2 / 10 year SANRAL Pothole Repair Cost -R 700 R1500 m 2 -SANRAL In-situ Recycle -R 250 R500 m 2

17 Road Condition What is Asset Management? Good Fair Poor B A 20 Very Poor (Typically Designed for Traffic Expected over Years) Year Two Roads, same condition & traffic but only budget for one?

18 Routine Maintenance Costs Per Year (R/m 2 ) Asset Management = Planning Optimal Zone At SANRAL = R 6.50 / m 2 per year Degree of Planning Preventative Maintenance Reactive Maintenance Total Maintenance

19 Asset Management System Building Blocks/Puzzle Pieces of AMS Policy/ Procedures Funding People Hardware Software Data Policy/Procedures Principles/Rules to Guide Decisions and achieve rational outcomes what, where, when, how. Funding Financial resources for operation and results implementation. People - People make decisions, the rest are just to support the process. Hardware Road Survey Equipment + IT Infrastructure. Software Computer based data Analysis and Storage Tools. Data Knowing what you have, its condition and performance Trend.

20 Asset Management System - Success Funding Policy/ Procedures People Hardware Data Software For asset management to be successful all the pieces of the puzzle need to be in place in a balanced equilibrium It does not help you have the most advance survey vehicle but no means to effectively store and analyse the data, or Have the most sophisticate software, but the quality of your data is suspect! Without Funding and People Nothing will happen!!!

21 AMS Hardware - Pavement Data Various condition parameters collected using SANRAL Road Survey Vehicle: Roughness how bumpy is the road speed, wear, etc Rut Depth how much water pond on surface - safety Macro Texture assist vehicle tire to drain water safety, noise Cracking how much water will get in - deterioration Alignment (DGPS) Speed, Fuel Consumption, etc ROW Video Road Signs, Section Measurements, etc Annual Surveys at 100 km/h

22 AMS Software Road Inventory Semi-Automated Data Analysis for data extraction

23 AMS Software - Real-Time Crack Analysis Real-time analysis during recording!!!

24 AMS Hardware - Pavement Data Structural Strength (Surface Deflection (mm)) Measured using Falling Weight Deflectometer (FWD) Simulates truck wheel traveling at 80 km/h over road pavement surface Surface deflection bowl is analyzed to establish the structural strength and remaining life of a pavement 100 % of the 200 m intervals every 5 years Traffic Speed Deflectometer

25 SANRAL TSD DATA OUTPUTS 3D Laser Point Clouds 3D Surface Images 2D/3D Surface Images

26 AMS Data - Bridges Visual Assessments (DER) Bridge condition is assessed through a standardized procedure to determine the Degree, Extent and Relevancy. Bridge repairs are prioritised according to severity and Relevancy of defects 3 to 5 year cycle 8000 Bridges & Major Culverts 0

27 AMS Data Traffic Traffic Event Logger (TEL) Inductive Loop Based Technology (1000) + Piezo (200) + WIM (45) Cluster Monitoring 1 to 3 year for Secondary Stations

28 AMS Data -Vehicles Operating Costs Up to 90 % of Total Transportation Costs Vehicle Operating Costs (Fuel, Tires, etc) Standard Vehicles (i.e. HDM-4 ) Congestion (i.e. HDM-4 ) Accident Costs Value of Time (Congestion) And Then!!!
