沥青路面面层的压实是一道极其重要的工序。经过压实，沥青路面才能达到规定的密实度和平整度，并改善表面结构，使沥青路面防滑指数、抗水性达到规定的要求。压实一般分为三步：初压、复压和终压。而初压对于沥青路面最终密实度具有决定作用。实验表明，提早初压能提高压实效
Compaction of asphalt pavement is an extremely important process. Compaction, asphalt pavement in order to achieve the required density and flatness, and improve the surface structure, the asphalt pavement slip resistance, water resistance to meet the requirements. Compaction is generally divided into three steps: initial pressure, pressure and final pressure. The initial pressure for the final density of asphalt pavement has a decisive role. Experiments show that early initial pressure can improve the compaction effect
