Abstract In order to improve the performance of asphalt concrete under heavy traffic, cement as reinforcement is used to mix with emulsified asphalt in asphalt mastic. But cement and emulsified asphalt is hard to mix well. Thus, F-type superplasticizer (FSP) as the isolation layer outside the micelles in cationic emulsified asphalt (CEA) is used in cement asphalt mastic (CAM).
