The common provincial road adopts two, three and four-level highways, and the width of the road adopts different widths according to the different design vehicle speeds. Road along-road greening is to add organic natural colors to inorganic roads, and is a main factor of environmental landscapes. The landscape design for greening the road along the way is not only designed as a shielding belt of a separation belt and a traffic lane, but also meets the landscape requirement and the safety of the whole road along the way and the expressway. The good greening design can not only lighten the influence of the road on the environment, but also keep the ecological balance of animal and plant kingdom, so that the whole road space is full of vigor. Automobile exhaust can bring a certain degree of Pb pollution to soil at two sides of a road and greening trees, and the greening belts in the middle or at two sides can play a role in protecting the Pb pollution, so that a good greening belt is a necessary condition of a good road.
At present, the domestic green belts are only provided with one planting layer, the water storage rate of soil is very poor, and when the green belts are subjected to heavy rain or ultra-heavy rain, the green belts can not store water well, and thus, great runoff is caused; if the road subgrade is not good in waterproof, the subgrade can be soaked by the infiltration rainwater, and the road subgrade has great harm to the service life of the road and the like.
