高速公路沥青路面表面层受雨水和车轮辗压的作用,容易出现表面层松散,坑洞、拥包、纵横向裂缝以及雨水沿缝下渗形成的啃边、局部沉陷、翻浆等现象。这些病害一般都发生在雨季,基本上都与水有关。水损坏影响路面的整体稳定性和强度,降低路面的耐久性。为此,围绕沥青路面水损坏的特性及成因进行了探讨,并结合时间工作经验总结了水损坏的预防措施。
The surface layer of highway asphalt pavement is easily affected by rain and wheel rolling. The surface layer is prone to loosening, potholes, embracing, vertical and horizontal cracks and infiltration along the seams, local subsidence and so on. These diseases usually occur in the rainy season and are basically water related. Water damage affects the overall stability and strength of the pavement and reduces the durability of the pavement. Therefore, the characteristics and causes of water damage in asphalt pavement are discussed, and the prevention measures of water damage are summarized in the light of working experience of time.
