排水沥青路面表面强化技术

Surface Strengthening Technology of Porous Asphalt Pavement

为验证渗透性树脂材料在排水沥青路面应用的可行性,以新建排水沥青路面的表面强化渗透性树脂材料为基础,通过肯塔堡飞散、车辙板渗水、湿轮磨耗等一系列试验预估和评价其对新建排水沥青路面的表面强化效果;并进行实体工程应用,论证本试验材料的实用性能。结果表明,该材料能够有限地抑制路面早期飞散病害的发生,从而延长路面使用寿命。

In order to verify the feasibility of applying permeable resin material in porous asphalt pavement, based on the permeable resin for surface strengthening of the newly built porous asphalt pavement, the strengthening effect was evaluated through a series of tests such as Cantabro test, permeability test on rutting plates and wet track abrasion test. And practical application was conducted to demonstrate the properties of the tested material. The results show that the material can limit the occurrence of raveling disease of asphalt pavement in early stage, thus prolonging the service life of the road.
