The Effect of Material Composition on Abrasive Resistance of Pavement Concrete

To research the effect of material composition parameters on pavement concrete, parameters such as the amount of cement, water-cement ratio, ratio of coarse and fine aggregate, mortar volume component, and air content are tested by rotating cutter method. Recommended ranges of material composition parameters are given on this basis. The result shows that the abrasion loss only decreases by 8% by increasing the amount of cement under the condition of the same water-cement ratio, but it decreases by 50% when to decrease the dosage of water. When the water-cement ratio is at a quite small value, the abrasion loss can decrease by 60% by increasing mortar volume component. Abrasion loss increases 56% when the ratio of coarse and fine aggregate is at a quite low value. It increases by more than 30% when the air content is bigger than 4%.
