高等级公路路面破损的特点及原因分析

公路在交通荷载和自然环境的共同作用下,路面会逐渐变得凹凸不平,出现各种破损现象,并且这些破损会随着时间的推移而日益严重,直接影响汽车行驶的速度、安全性和舒适性,增加道路的运营费用。为了评估和预测各种破损对路面使用性能和运营费用的影响,需要研究各种损坏产生的原因。为此,本文将对我国高等级公路路面常见损坏的特点和原因进行分析和归纳。

High-Grade pavement damages and their classification

Highway is performed under the transportation loads and the nature environment effect; it would gradually appear the convex caves and many kinds of damage phenomena, which would become increasingly serious along with time. When those damages add up to a certain degree, they will affect the car speeds, safety and comfort, and increase the pavement transportation expenses in future. In order to estimate and predict their influence on pavement performance and transportation expenses, we should need to study the reasons which lead to produce these damages, and proceed a reasonable classification to compute precisely the influence on pavement performance and service life.
