影响沥青路面平整度的原因分析

Analysis the Reasons of Impacting on the Smoothness of Asphalt Pavement

路面的平整度是高速公路路面的主要使用性能之一,优良的平整度能保证车辆高速、舒适、安全地行驶,并对路面的养护费用和使用寿命有显著影响。我国高速公路在开放交通2～3年后,路面的平整度都有不同程度的降低。本文就高速公路路面平整度降低产生的原因进行了详细分析,并对提高路面平整度提出了相应的几点看法。

The smoothness of the pavement is one of the main highway pavement performances. The better smoothness can ensure that the vehicles run with high - speed, comfortable, safe. And the smoothness impact on the pavement maintenance costs and service life. In China, after highway is used for two or three years, the smoothness of pavement has different degrees of lowered. In this paper, the reasons of highway pavement lower are analyzed in detail, and a few comments about improving the smoothness of pavement are put forward.
