随着高等级公路的迅速发展,行车速度也不断的提高,因此人们对于路面平整度的要求也越来越高。但很多高等级公路在长期的正常使用过程中均不同程度的出现了起拱、坑凹、波浪、接缝台阶、碾压车辙等路面不平整的现象。平整度是评价高速公路施工质量的一个重要参数。平整度的好坏。直接影响到汽车行驶速度、油料消耗、车辆磨损、行车舒适性和安全性。也是人们对高速公路养护质量最直接的外观评价。
With the rapid development of high-grade highways, the driving speed is also constantly increasing, so people are demanding more and more of the road surface roughness. However, many high-grade highways have different degrees of irregularities in the arch, pits, waves, seam steps, rolling rut and the like during the long-term normal use. Flatness is an important parameter to evaluate the quality of expressway construction. Smoothness is good or bad. Directly affect the car speed, fuel consumption, vehicle wear, driving comfort and safety. It is also the most direct appearance evaluation of the people on the highway maintenance quality.
