路面平整度是路面表面诱使行驶车辆出现振动的高程变化,它可以用仪器进行量测。而乘客对振动的感受和接受能力带有主观性,往往采用小组评分的方法进行主观评定。路面使用初期的平整度与施工技术水平、施生质量控制、面层构造和材料等因素有关。而在使用期间,随着车辆荷载的反复作用、周围环境周期变化的影响以及路面龄期的增加,路面的平整度会随着各种路面病害的出现而逐渐下降。当平整度下降到一定的期限时,路面便不能满足基本功能的要求,而需采取适当的改建措施以恢复其功能。本文阐述了路面不平整的原因及其对路面的影响。合理选择摊铺机,确保路面的平整度。
Road surface roughness is induced by the road surface vibration of vehicles moving elevation changes, it can be measured with the instrument. Passengers on the vibration of the feelings and acceptability subjectivity, often using the method of group rating subjective assessment. The smoothness of the initial use of pavement is related to the technical level of construction, the quality control of production, surface structure and materials. During the period of use, with the repetitive effect of vehicle load, the influence of the change of the surrounding environment cycle and the increase of the road surface age, the road surface roughness gradually decreases with the appearance of various road diseases. When the flatness drops to a certain period of time, the road surface can not meet the requirements of the basic functions, and proper reconstruction measures need to be taken to restore its function. This article describes the causes of road roughness and its impact on the road. Reasonable choice of pavers to ensure the smoothness of the road.
