Study on Performance of Prefabricated Pervious Composite Cement Concrete Pavement
Prefabricated pervious composite cement concrete pavement is widely used in pavement con-struction.In order to explore the influence of different strength grades of ordinary Portland cement on the performance of prefabricated pervious composite cement concrete pavement,this paper relies on practical projects.The 28d compressive strength,27d flexural tensile strength and permeability coefficient of prefab-ricated pervious composite cement concrete pavement prepared by using three different strength grades of ordinary Portland cement were tested.The experimental results show that when the cement strength grade is 42.5,The prefabricated permeable composite cement concrete pavement can obtain good compressive strength and high flexural and tensile strength,and can meet the requirements of specifications and construction.
