The Enhancement Effect of Hydrated Lime on Glassphalt Concrete

Abstract:

Adding the glass will make the cohesion property of HMA (Hot Mix Asphalt) worse. we often improve the antistrip performance of conventional HMA by the means of adding hydrated lime. In this article, we compare the effect of two different patterns of adding hydrated lime. The test reveals that: replacing the mineral power with hydrated lime can improve the overall performance of mix; With respect to mixing the hydrated lime with asphalt in advance, the water stability of concrete increase more, if the mineral power is replaced by equivalent; Although it can’t do a favor to the mix’s low temperature performance, mixing the hydrated lime with asphalt in advance can significantly improve the high temperature performance, it can be used in high temperature region while it rains rarely.
