Expansion Device Construction Technique for the Bridge of Tonghua - Meihekou First Class Road
In the past, expansion device is usually constructed before asphalt paving, but it will cause the jumping car phenomenon, TONG - MEI first class highway adopts the asphalt single paving (full of sand - gravel in the expansion joint, the height of the sand - gravel is equal to the elevation of the asphalt pavement subsurface), then cutters silt to fix the expansion joint. It is an efficient solution to the jumping car phenomenon. This paper illustrates this construction technique.
