The Influence of Cement and Hydrated Lime on the Performance of Asphalt Mortar

This article research the influence of cement and hydrated lime on performance of asphalt mortar. Through the performance test of mortar in different replacement quantity, it is found that adding cement can increase soften point, viscosity decrease, and low temperature character is improved. But when the displace quantity exceed 60%, the improvement extent decrease, so the cement quantity should not exceed 60%. When adding hydrated lime, the soft point and viscosity of mortar is increased notably, but low temperature performance is deteriorated form BBR test. But when the quantity of hydrated lime is less than 20%, the influence on low temperature performance is little.
