Abstract: Semi-flexible pavement is a kind of composite pavement that utilizes the pore structure of open-graded asphalt mix which is subsequently filled with an appropriate cementitious mortar. The main purpose of this research was focused on the influences of W/B ratio, S/B ratio and using of superplasticizer on the performance of cementitious mortars for semiflexible pavement. 14 kinds of mortars were designed and studied to investigate the trends of the mortars with different W/B ratio, S/B ratio and superplasticizer dosage. Based on the study, cementitious mortar with the combinations of good workability, high strength and low drying shrinkage was prepared by using polycarboxylic acid superplasticizer and expansion agent under the proper mix proportions. The evaluation of the semi-flexible pavement material containing this kind of cementitious mortar indicated its high capacity and great potential to reduce the permanent deformation under high temperature and heavy traffic loading.
