掺水泥花岗岩沥青混合料的性能研究与应用

在公路建设中使用酸性集料铺筑沥青路面,必须掺加抗剥落剂来增强与沥青的粘附性。文章通过马歇尔残留稳定度试验、冻融劈裂强度试验以及高温车辙试验,对酸性花岗岩掺加水泥沥青混合料路用性能与未掺加抗剥落剂碱性石灰岩沥青混合料的性能进行对比研究,表明掺水泥抗剥落剂的花岗岩沥青混合料的性能完全满足规范要求,可应用于公路建设中。

Research on the performance of granite asphalt mixture with cement and its application

When paving asphalt pavement with acidic aggregate in highway construction,anti-stripping agent must be added to enhance the adhesion of asphalt.Through Marshall residual stability test,freeze-thaw splitting strength test and high-temperature rutting test,the paper comparatively studies the pavement performance of acidic granite asphalt mixture with cement and alkaline limestone asphalt mixture without anti-stripping agent,which shows that the performance of granite asphalt mixture with cement anti-stripping agent fully meet the standard requirements and the anti-stripping agent can be applied to highway construction.
