The application of Multi-function Road Surface (MRS) in the anti-skid maintenance of steel deck of Zhongshan Guangming Bridge was introduced and the mechanical properties of MRS binder and the high temperature stability, water stability, adhesive property of MRS pavement were comprehensively studied. The results indicated that MRS binder had excellent bond strength and durability, MRS pavement had excellent high temperature stability, water stability, adhesive properties, and the skid resistance of the steel deck was improved significantly. The bond strength of MRS binder to steel and tensile lap-shear strength of MRS binder were 19.2 MPa and 17.6 MPa, respectively, and its bond strength to concrete was 3.1 MPa with all breaks found in concrete. After exposure to damp heat for 20 days and 5 high-low temperature cycles, the bond strength of MRS binder was 3.2MPa and 3.3MPa, respectively, and all breaks of the samples were found in concrete. The dynamic stability of MRS pavement was 25245 times/mm at 70 °C, 0.9 Mpa, and its immersion Marshall residual stability was 95.4%, and the bond strength of MRS overlay was 4.4MPa. The British pendulum number of the deck at dry and wet state was increased from 60, 36 to 97 and 86, respectively. And the water permeability coefficient of the MRS pavement was 0 ml/min. © 2015 IEEE. Source
