Using Corundum to Improve Skid Resistance of Pavement Made of Engineered Cementitious Composite

Engineered Cementitious Composite (ECC) is a unique type of high performance fiber-reinforced cementitious composite. ECC has very high tensile ductility, thus, a high flexural strength of more than 10 MPa, which makes ECC a great material for pavement application. However, as a cementitious material, ECC surface is slippery. Common practices to improve the skid resistance in concrete pavement like broom drag or grinding, etc. cannot be applied for ECC due to the presence of fiber and the lack of coarse aggregate. Therefore, in this research, corundum, a hard and durable material is introduced into ECC mixture in order to improve ECC’s skid resistance. A certain percentage of fine sand in typical ECC mixture was replaced by corundum. Samples were prepared for testing flexural strength and skid resistance. The results showed that the modified ECC with corundum has very high flexural strength of more than 10 MPa. The ECC with corundum, which was exposed aggregate within one day after casting, provides high skid resistance that fulfills the highest requirement for new roads for example in Singapore. The mean texture depth (MTD) of the exposed ECC with corundum is also higher than typical ECC. Further, MTD can also increase with the introduction of grooves. And even after 100,000 load cycles under traffic simulation, the skid resistance of the exposed ECC with corundum remains very high. The extrapolation results indicated that ECC with corundum can fulfill the skid resistance requirement until the end of the pavement life time without any further intervention.
