摘要
将辉绿岩粗集料用于城市主干道下面层AR-AC16路面,并进行集料性能实验、集料与结合料黏附性实验及橡胶沥青混合料路用性能实验。结果发现:除黏附等级不满足规范要求外,辉绿岩其他物理力学指标优良,采用水泥替代矿粉并掺加抗剥落剂后,辉绿岩橡胶沥青混合料表现出优良的路用性能,其中残留稳定度超过90%,比未掺加前提高40%以上,AR-AC16动稳定度高达4 700,冻融劈裂强度比有明显提高,低温小梁实验结果亦满足规范要求。辉绿岩粗集料可用于高等级沥青路面中下面层。
Using diabase coarse aggregate on AR- AC16 for urban main road,and aggregate performance test,aggregate and binder adhesion test and performance test of rubber asphalt mixture. The results show that：in addition to the adhesion level does not meet the requirements of specification,greenstone other excellent physical and mechanical indexes,with cement for mineral powder and adding antistripping agent,diabase rubber asphalt mixture showe excellent road performance,including residual stability more than 90%,more than40% higher than that of before adding,AR- AC16 dynamic stability is as high as 4700,freeze- thaw splitting strength than to have improved obviously,low temperature tm test results meet the requirements of specification,diabase aggregate can be used for high grade lower surface layer of asphalt pavement.
