合理的轴重限值应使公路基建、养护费用和汽车运输成本的总和在一定时期内为最低值,同时兼顾军事运输、节约能源和交通安全、并避免噪音、废气过度污染环境. 一、国外轴重限值发展状况发达国家轴重发展过程值得借鉴.由于大吨位车辆运输成本低,有利于开展集装箱运输和大件运输,各国轴重限值都不断提高.现在美国和苏联的单轴重限值约12吨,双联轴重限 Reasonable axle load limit should make the sum of road infrastructure, maintenance costs and motor transport costs in a certain period of time for the lowest value, taking into account the military transport, energy conservation and traffic safety, and to avoid noise, excessive emissions of waste gas environment. Axle weight limit development status Axial weight development in developed countries is worth learning.Due to the low cost of large-tonnage vehicles transport, container transport and large transport conducive to the development, the national axle load limit values ​​are continuously increasing.Now the United States and the Soviet Union, the uniaxial weight The limit of about 12 tons, double axle limit
