Mitigating Moisture Susceptibility of Asphalt Mixes
The objective of this proposal research is to investigate the use of waste by product materials in mitigating moisture susceptibility (stripping) in hot asphalt mixes through a laboratory testing program. Two types of aggregates from different sources will be investigated while hydrated lime and two new liquid anti-stripping agents will be added. The performance of asphalt mixtures with these three additives will be compared with a control asphalt mixture in which neither the aggregate nor the binder is treated. A cost effectiveness analysis will be conducted to evaluate the economics of these three agents.
