Experimental Study on Pavement Performance of Emulsified Asphalt Cement Concrete

Based on the research and indoor experiments, this paper investigates the mixing and curing techniques, pavement performance, and influencing factors of emulsified asphalt cement concrete. The results indicate that mixing sequence of raw material and curing condition have great impact on the strength of the mixture. Adding cement to mixture can improve the pavement performance of mixture greatly. However, increasing the content of emulsified asphalt has opposite effect. Proper content of emulsified asphalt will ensure the bonding strength and waterproof property of the mixture. The critical factors that influence the pavement performance of emulsified asphalt cement concrete are asphalt cement ratio, water cement ratio, content of emulsified asphalt and cement, sand percentage, and aggregate gradation.
