1 路面裂缝的形成与分析淮阴市干线沥青路大多是70年代改造的“强基薄面”的路面结构,基层为石灰稳定土,面层为沥青或渣油表处。使用多年后面层逐步老化,加上水分乘机侵入,逐渐发展成龟裂、松散、坑凼以致路面损坏,失去工作能力。但其基层一般仍具有良好的强度,在一定条件下还能维持现有交通。因此,在基层还没有产生整体破坏的情况下,及时对网裂路面采用乳化沥
1 Formation and Analysis of Pavement Cracks Most of the asphalt pavement in Huaiyin City is the pavement structure of “strong base and thin surface” modified in the 1970s. The base layer is lime stabilized soil and the surface layer is asphalt or residual oil surface. After many years of use, the surface layer is gradually aging.
