| 摘 要： | 当沥青面层的空隙率偏大,透水性也因此相对较大时,在高速行车引起的动水压力作用下,外界水极易侵入面层内部并逐渐积聚;在行车荷载的反复作用下,面层内部的混合料发生剥落,剥落的沥青向上迁移,由此造成了油斑泛油和内部松散现象.为此,分析沥青路面初期损坏的产生机理有一定的价值.

| Abstract: | When the porosity of asphalt surface layer is large and water permeability is relatively larger,external water is easy to invade the interior of surface layer and gradually accumulates under the pressure of movement water causing by high-speed traffic.The mixture in surface layer peels off by repeated traffic load,the asphalt migrates upwardly and the phenomenon of oil spot weeping and internal loose happens.Therefore,it has certain value to analyze mechanism of early damage of asphalt pavement. |
