目前,根据道路状态的检查与评价结果来确定和规化道路维修实施方法,其缺点在于规定的那些道路工作状态与标准要求不符,出现了不允许的变形和破坏,以及现行道路的参数、指标与复杂的交通密度和组成不符.这样一来要提高道路的运输一经营,就必须预报在复杂交通密度和组成下道路的变形,破坏的形成及发展过程.通常在第一阶段,路面、路基和其它道路部份的变形发展是很慢的,而以后开始急剧增加,出现个别或大量的破坏.要消除变形和破坏包括预防的办法采用越晚则所要的经费就越多.这是由于降低车速,道路运输损失增大;交通事故油脂燃料消耗、轮胎磨损加大;以及维修费用增多等原因造成的.
At present, according to the result of inspection and evaluation of the state of the road, the method of determining and regularizing the road maintenance is disadvantageous in that the stipulated working state of the road is inconsistent with the standard requirements, the impermissible deformation and damage occur, and the parameters and indicators of the current road Which is inconsistent with the complicated traffic density and composition.Therefore, in order to improve the transportation of a road, it is necessary to predict the formation and development of the road deformation and destruction under the complex traffic density and composition.Usually in the first stage, the pavement, roadbed And other parts of the road are slow to develop and begin to increase sharply in the future with a few or a large number of damages and the more funding is required to eliminate the methods of deformation and destruction including prevention, Speed, loss of road transport increased; fatal fuel consumption in traffic accidents, increased tire wear and tear; and increased maintenance costs and other causes.
