随着现代高速公路的发展,施工质量的要求将越来越来高,然而,路面平整度必然成为筑路施工的重要环节。本人就沥青路面摊铺时、机械和材料、施工方法等产生不平整的原因进行分析,并提出相应的处理措施。一、面层材料对平整度的影响1、混合料的级配设计是一项精细、严谨的工作,若级配不合理,骨料粒径偏大,稳定性虽好,但密实度不能保证:骨料粒径过小,碾压时会造成横向位移,影响摊铺速度和平整度;沥青混合料的拌和不均匀,也会影响路而
With the development of modern expressway, the requirements of construction quality will be more and more high. However, the smoothness of pavement will inevitably become an important link in road construction. I paved the asphalt pavement, machinery and materials, construction methods, such as the reasons for the formation of uneven analysis and put forward the corresponding treatment measures. First, the effect of surface material on the flatness 1, the grading design of the mixture is a fine, rigorous work, if the gradation is not reasonable, the aggregate size is too large, the stability is good, but the density can not be guaranteed : Aggregate particle size is too small, rolling will cause lateral displacement, affecting the paving speed and smoothness; Asphalt mix uneven mixing will also affect the road
