半柔性路面试验设计与效果评价

Test Design and Effect Evaluation for Half-flexible Pavement

文中提出了一种新型的路面复合材料——半柔性路面用混合料,它是在开级配的多孔基体沥青混合料中,灌入以水泥为主要成分的特殊浆剂,从而提高沥青混合料的高温稳定性、耐油性及抗疲劳等性能。通过铺筑试验路,进一步验证了半柔性路面确实具有高温稳定性、抗滑性能、耐水损害性能和抗疲劳特性等显著优于沥青路面的良好路用性能。

This paper put forward a type of new compound material, mix for half-flexible pavement. It is made up of open-graded multi void asphalt material, adding a kind of special slurry cement component, then enhance the high temperature stability, anti-oil and anti-fatigue ability. By constructing test section, this kind of mix shows better character than normal asphalt pavement.
