路面平整度是道路的一种质量特征,车辆在不平整的道路上行驶,不仅影响旅客和司机的安全与舒适性,而且增加车辆的运行费用(例如增加油耗,降低行车速度和车辆使用寿命,延长出行时间),同时还会加速道路结构的破坏,影响路面的使用年限和养护周期。因此,随着对公路服务质量要求的不断提高及路面管理系统的建立,平整度成为目前路面使用性能最重要的指标之一。平整度的控制必须通过路基、基层、面层各个层面的精心施工方能得以保证。现行规范《公路路基路面现场测试规程》中规定了三个测定平整度的试验方法:T0931-95 3m直尺测定平整度试验方法;T0932-95连续式平整度仪测定平整
Road surface roughness is a quality characteristic of the road. Vehicles running on uneven roads not only affect the safety and comfort of passengers and drivers, but also increase the running costs of vehicles (such as increasing fuel consumption, driving speed and service life of vehicles, Extend travel time), but also accelerate the destruction of the road structure, affecting the life of the road and maintenance cycle. Therefore, with the continuous improvement of highway service quality requirements and the establishment of pavement management system, flatness has become one of the most important indicators of pavement performance. The control of flatness must be guaranteed through meticulous construction at all levels of roadbed, grassroots and surface layers. The current standard “Highway Subgrade Pavement Field Test Procedures” provides three test methods for measuring flatness: T0931-95 3m ruler test flatness test method; T0932-95 continuous flatness meter flattening
