Study on Water Stability of Bitumen Mixture Under High Temperature and Moisture Conditions

摘要

The Work made use of two different asphalts-Shengli and Kalamayi and two different aggregates-Granite and Lime-stone to study the performance of asphalt mixtures under high temperature and moisture condition. Two modifers AST-3 and hydrated lime were investigated as prospective performance enhancers. Film stripping and marshall's Retained stability tests were used to determined the adhesion characteristics and Moisture susceptibility of mixture, immersion wheel tracking test was used to study the rutting potential at high temperature in the presence of moisture.
