山西省高等级公路沥青路面通常采用以半刚性基层为基础的“强基薄面”结构,该结构具有“足够的强度、适宜的刚度、较小的变形、良好的抗裂性”等优点,很好地解决了沥青路面的车辙问题。然而,这种路面也有其固有的缺点。因半刚性水硬性材料收缩变形(温缩、干缩),该结构路面基层容易开裂,路面会出现反射裂缝。这种裂缝已成为我国高等级公路沥青路面的主要破坏形式,大大缩短了沥青路面的使用寿命。另外,
Asphalt pavements for high-grade highways in Shanxi Province generally adopt a “strong base thin-faced” structure based on a semi-rigid base which has sufficient strength, suitable rigidity, small deformation and good crack resistance. And other advantages, a good solution to the rutting problem of asphalt pavement. However, this pavement also has its inherent disadvantages. Due to the shrinkage deformation (shrinkage and shrinkage) of semi-rigid hydraulic materials, the base of the structure is easy to crack and the reflection cracks appear on the pavement. This kind of crack has become the main form of destruction of asphalt pavement of high-grade highway in our country, which greatly shortens the service life of asphalt pavement. In addition,
