The Research on Pavement Maintenance Management of Beijing-Tianjin-Tanggu Expressway

The Beijing-Tianjin-Tanggu expressway is the first highway which is built by using World Bank loan in china. With the influence of service life increasing and traffic growing, the diseases appear such as rut, crack and poor flatness, so the use performance of the highway obviously degrades. Pavement overhaul effectively reduces the appearing of pavement diseases and prolongs the service life of the road. This paper conducts a detailed research on the engineering management and construction quality control of the Beijing-Tianjin-Tanggu expressway overhaul which has strong reference significance on highway overhaul.
