在公路特别是高等级公路施工中,影响沥青路面平整度的因素很多,主要有路基因素、沥青混合料因素、机械因素等。下面就施工过程中机械因素对沥青路面平整度的影响加以说明。1.机型选择不当的影响(1)摊铺机选型不当在摊铺宽度为14m左右时,多用2台摊铺机并机摊铺作业。此时若选用同一 In highway construction, especially high-grade highway, there are many factors affecting the smoothness of asphalt pavement, mainly including road foundation factors, asphalt mixture factors and mechanical factors. The following on the construction process of mechanical factors on the asphalt surface roughness to illustrate. 1. Improper selection of models (1) Pavement improper selection In the paving width of about 14m, the use of more than 2 pavers and paving operations. At this point if the same choice
