Construction Technology of Subgrade and Pavement Widening in Expressway Reconstruction and Expansion
In the current situation of increasingly perfect domestic infrastructure facilities,for the development of transportation,if the expressway has stronger bearing performance,it can better meet people's needs for transportation.At present,the expressway is gradually saturated.In order to solve this problem effectively,more manpower and material resources should be invested to study the reconstruction and expansion of the expressway.In this paper,a detailed analysis of subgrade and pavement widening technology is carried out,and the key points and precautions of construction are discussed so as to promote the further improvement of technology application effect.
