密水型高模量沥青砂试验研究

Study on the test of high modulus asphalt sand

对密水型高模量沥青砂混合料进行设计,通过对SBS改性沥青砂、HSA高模量沥青砂、HSA浇筑式沥青混凝土的路用性能进行比较分析,得出AC-5密水型高模量沥青砂具有较高的沥青含量和较低的空隙率,具有良好的高低温性能、水稳定性、和抗疲劳性能。

In this paper, the dense water type high modulus asphalt sand mixture is designed,by comparative analysis on pavement performance of the SBS modified asphalt sand, HSA high modulus asphalt sand, HSA casting type asphalt concrete,it comes to the conclusion that the AC-5 dense water type high modulus asphalt sand has higher asphalt content and low porosity,good performance of high and low temperature,water stability,fatigue resistance performance.
