Overview of Sample Projects Developing a New Generation of Thin Overlay Mixtures ZEBRA Asphalt Mix Technology
THE PROBLEM Basalt is the only available aggregate in Israel which provides sufficient skid resistance to Asphalt Surface Layers Only three active quarries which don t t stand up the demand Delays in paving projects, in the quality of the aggregate and skyrocketing costs

ZEBRA Asphalt Mix Technology Two types of Asphalt mixtures: SMA and S Several combinations of coarse aggregates : basalt + 2 types of dolomite / limestone ( ZEBRA ) Eight test sections
ZEBRA MIXTURES
ZEBRA MIXTURES PROJECT Conventional SMA-Basalt vs. ZEBRA SMA
Research and Economy Reduction of 10% in basalt cost = Reduction of 44-73 Million NIS in INRC costs Reduction of 25% in basalt cost = Reduction of 110-183 Million NIS in INRC costs The cost of the two research projects 1 Million NIS

23rd ARRB Conference - Reducing Carbon Footprint Thank you to all those delegates who actively ensured their carbon footprint was minimised during the Conference. Additional thanks go to those delegates who accepted to pay an optional extra on their Conference registration. This donation raised $900 towards offsetting the carbon emissions generated by the Conference. Through Carbon Neutral, a not-for-profit organisation, $450 of the money raised has gone towards Trees for Sequestrian biodiversity planting in South Australia and $450 has gone towards Carbon Sequestrian research. This has resulted in the planting of approximately 150 trees and the reduction of 20 tonnes of CO2. Additional donations to Carbon Neutral can be made via their website www.carbonneutral.com.au ARRB Group Ltd
