路面平整度是评定路面质量的主要技术指标之一,它关系到行车的安全、舒适以及路面所受冲击力的大小和使用寿命,对高等级公路来讲,平整度指标就更为重要。影响路面平整度的因素是多种多样的,涉及到设计、施工、自然条件等方方面面。多年来的沥青混凝土施工经验告诉我们,影响沥青混凝土路面平整度的因素从施工角度来讲,主要为不均匀沉降;摊铺工艺;碾压工艺;横接缝处理;配合比设计;下承层病害等。但主要为摊铺工艺、碾压工艺及横接缝处理。
Pavement roughness is to assess the quality of the pavement one of the main technical indicators, it is related to driving safety, comfort and the impact of the road surface the size and service life, for high-grade highways, flatness index is even more important. Affect the smoothness of the road is a variety of factors, involving design, construction, natural conditions and other aspects. Years of asphalt concrete construction experience tells us that the impact of asphalt concrete pavement flatness factors from the construction point of view, mainly for uneven settlement; paving process; rolling process; horizontal joint processing; mix design; the lower bearing layer Diseases and so on. But mainly paving process, rolling process and horizontal seams.
