随着社会经济的迅速发展和交通量的迅速增长,道路出现了不同程度的病害和破损,已影响行车的安全性和舒适性。对老路的改造设计迫在需要,对原有公路改造,对老路现状调查十分重要,老路的现状直接影响到改造方案、工程投资。笔者参加了改造设计,以老路实地测量、平纵拟合、实地调查、实测弯沉值等资料为依据,对老路路面改造提出设计方案,为同仁提供借鉴。 With the rapid socio-economic development and the rapid growth of traffic volume, roads have experienced varying degrees of disease and damage, which have affected the safety and comfort of traffic. It is necessary to reform and design the old road, which is very important to the original road reconstruction and the investigation of the current status of the old road. The current status of the old road has a direct impact on the reconstruction plan and project investment. I participated in the transformation of the design, the old way to measure the field, the vertical and horizontal fitting, field surveys, measured deflection and other data as the basis for the renovation of the pavement design proposed for colleagues to provide reference.
