(2) The horizontal and vertical impact forces generated by vehicle jumps can further damage road surfaces, road beds and bridge structures, increase maintenance and repair costs and management difficulty, and reduce road performance. (3) The impact force during jumping can generate adverse reaction force to the vehicle, increase the vibration and mechanical wear of the vehicle and the wear of tires, increase the oil consumption, shorten the service life of the vehicle and increase the transportation cost. (4) Vibration and noise generated during jumping can cause noise pollution to drivers and residents on two sides of a road, so that physical and psychological health of people is not facilitated, and normal work and life of the people are influenced.

The gelled gravel material is prepared by adding a small amount of gelling agent and water into natural gravel materials, waste materials or purchased crushed stones and the like of riverbeds or mountain areas near dam sites and mixing. When the cementitious loading is close to 0, the rigidity of the cementitious gravel material is close to that of the earthen material. As the gel loading increases, its stiffness gradually increases. When the gel mixing amount is higher than 120kg/m3When in use, the rigidity of the gelled gravel material is close to the rigidity of the abutment concrete. Therefore, the gelled gravel materials with various proportions are simultaneously applied to the bridge and roadbed reinforcing structure 3, and the problem of vehicle jumping caused by poor rigidity of the bridge and the roadbed can be avoided. The gravel material can be obtained from local materials, is safe, reliable, economical and environment-friendly, and has good seepage drainage effect.
