Study On Improvement Of The Pavement Performance Of Cement-stabilized Crushed Stones Under Heavy Vehicles

The asphalt pavement on cement-stabilized crushed stones base produces cracks easily so that the structure of pavement is destroyed too easily, specially under heavy vehicles. On the base of apply of local materials, Fly ash and regulate aggregate has been done to improve pavement performance of cement-bound crushed stones. In the process of mixture design, such as mechanical property shrinkage anti-freeze and durability, pavement performance is tested and verified to reach mixture optimum fly ash content and optimum mixture. Through study on effect of aggregate of pavement performance of cement-bound crushed stones, optimum aggregate is reached. Space in mixture is put forward, through analysis of relation of pavement performance of cement-stabilized crushed stones and space in mixture, optimum range of space in mixture is reached.
