Abstract
Based on the long-life test road of Yunluo expressway in Guangdong province, firstly, based on the theory of small disturbance elastic thin plate and the design code of the highway cement concrete pavement, the life analysis of the roller-compacted concrete pavement structure of the Yunluo long-life test road is carried out. The results show that the pavement structure can achieve a 53.2 years long-life. Secondly, in order to verify the reliability of the theoretical analysis results, the strain sensors and the temperature sensors were embedded in different layers of the test road. After years of continuous data collection and based on the constitutive model of the roller-compacted concrete material, the theoretical analysis of the results concluded that the pavement structure can achieve at least 45 years life. The results of theoretical and practical analysis show that the new type asphalt pavement structure on the roller-compacted concrete base can be used as a typical long-life asphalt pavement structure under high temperature, rainy and heavy load conditions in Guangdong province.
