【摘要】 在沥青路面使用过程中,沥青变硬是路面老化的表现,这是由于沥青路面长期暴露在空气中而造成的。如果我们能够阻止空气在路面内部孔隙中的流通,沥青变硬的速度也会明显降低。因此,如果有一种路面密封保护材料,能够将路面孔隙中和内部连贯孔封闭,则将会大大延长沥青路面的使用寿命。针对于此,对一种表面涂刷型沥青路面保护材料进行试验研究。更多还原

【Abstract】 Asphalt hardening is an oxidation process and as such is a function of exposure to air on the surface and within the pavement. If circulation of air through the interconnected void spaces can be prevented, the rate of hardening of the asphalt will be reduced and the life of the pavement extended. Therefore, it follows that’s a sealer which will close the pores will lengthen the life of the pavement. Aim for this, this thesis did some research works on the protect material which smeared on the asphalt pavement.更多还原
