Research on Key Techniques for Preventing Car Jumping at Expressway Bridgehead

At present, China's expressway construction is in a high-speed development stage, and the number of bridges, culverts and other structures is increasing day by day. Bump at bridge head is a common type of disease, which will not only reduce the comfort of driving, but also accelerate the damage rate of components such as abutment.Therefore, it is necessary to understand the harm of vehicle jumping at the bridgehead of expressway, standardize the construction technology and improve the construction technology level in combination with the actual situation of the project, so as to solve the problem of vehicle jumping at the bridgehead and improve the construction quality of the project.
