目前道路运输负荷逐年增大,采用沥青路面的道路面临面层开裂、车辙破坏等居多问题。随着我国的交通事业逐渐发展起来,道路的承载量变大,荷载也越来越大,这给道路施工的工人的技术以及路面的修复需要更好的要求。车辆行驶时,路面的平整与否直接影响行车的舒适度,对行车的安全隐患也起到尤其重要。 At present, the load of road transportation is increasing year by year. The road with asphalt pavement faces many problems such as surface cracking and rutting failure. With the gradual development of transportation in our country, the carrying capacity of the road becomes larger and the load is more and more large, which requires better requirements for the technology of road construction workers and the repair of pavement. When the vehicle is running, the smoothness of the road surface directly affects the comfort of driving, and the safety hazard of driving is also especially important.
