A new maintenance way on semi-rigid base material

In many regions, such as Tibet, Qinghai etc, because of its unique climate conditions, continual appear all kinds of road diseases, such as cracks, subsidence and damages. Mainly due to the traditional maintenance ways on semi-rigid base material in these regions are not very well. So based on the characteristics of semi-rigid base material and these areas with ample solar energy, a new maintenance way was proposed. Also this paper selects the best isothermal bags through the designed test, and verified its curing effect well.
