Research on laboratory simulation test method for skid resistance performance of chip seals

Chip seals are most frequently used as preventive maintenance treatments on asphalt pavements. The surface performance should be considered as a major factor in the project. A laboratory simulation test method for surface skid resistance of chip seals is established in this paper. A plate specimen of asphalt mixture by long-term aging treatment is used as the under layer, which simulates the original asphalt pavement structure. Followed by spraying emulsion asphalt, fiber glass (alternative reinforced material) and crushed stone aggregate, and initial rolling, the simulation process of construction for layered pavement is completed. The specimen is rolled intermittently by rubber roller and stored in a curing room alternately, to simulate the long-term compaction process by actual traffic loading. Then, the molding method of composite plate specimens is established, which considers the state of original asphalt pavement diseases and the construction process. Based on the above method, the different test parameters, such as rolling and maintenance temperature, frequency and interval time of rolling, rolling load, material type and material application rate and so on, are considered in the surface texture depth test and friction test. According to the dependency relation with the field tracking test results, the rolling and maintenance parameters are defined. It is concluded that the molding method of composite plate specimens and the test method can simulate, test, evaluate and predict the performance of chip seal pavements, especially the surface skid resistance.
