The results of the analysis show that the highway longitudinal grade had little influence on pavement performance.
分析结果表明，公路纵坡对路面结构受力的影响不明显。
The existing highway design criterion only takes setting pavement longitudinal grade, side ditch and drainage ditch into account in order to eliminate surface water.
现有的公路设计中，考虑较多的仅仅是通过设置道路的纵坡、边沟及排水沟等设施来排除地表水。
The emphasis of montane highway design is vertical alignment's design, there are usually two controls parameters: concessional maximal longitudinal and concessional maximal length of grade.
