沥青面层作为高速公路路面基层上最重要的路面结构层,它直接承受汽车车轮荷载和大气自然因素的作用,具有平整、坚实、耐久及抗车辙、抗裂、抗滑、抗水等多方面的综合性能。但沥青路面施工具有工艺复杂、难度大、技术含量高、造价高等特点,这就要求对沥青面层施工前对易出现的缺陷要进行仔细分析,找出原因,作好各项应对措施,避免较大的经济损失。
As the most important pavement structure layer of highway pavement basement, asphalt pavement is directly subjected to the influence of car wheel load and atmospheric natural factors, and has many advantages such as flatness, solidity, durability and anti-rutting, cracking resistance, anti-slip and water resistance The comprehensive performance. However, the construction of asphalt pavement has the characteristics of complicated process, high difficulty, high technical content and high cost. This requires careful analysis of the defects that appear before the asphalt pavement construction, find out the reasons, make various measures to avoid Greater economic loss.
