I use the asphalt concrete pavement, for two-way two-lane road is7 meters wide,Hard shoulder is meters wide , shoulder horizontal gradient of %, road arch horizontal gradient of 2%, the road has high all the way, the road high at 4%, do not set widened. Entire section of road has four plane curve, two vertical curve, the road smooth plane curve design meet the vehicle, comfortable principle, at the same time plane curve can package to vertical curve, namely "flat bag vertical" principle. Road slope stability calculation, retaining wall design, at the same time in order to meet the road drainage road design six culvert, in order to meet the requirements of road drainage so to calculate and determine the span of culvert road displacement, through the survey of jintang county local hydrological conditions calculated the parameters of the culvert.
