China is there is no specific bumping at bridge-head method of discrimination at this stage, and highway administration maintainer author is usually only into every trade
Vehicle is investigated, and only when bumping at bridge-head is more serious, could be judged it.Due to bumping at bridge-head evaluation result and vehicle shape
Condition and personnel's experience have much relations, thus existing judging result can not quantitative description vehicle bump degree.And the later stage is logical
Vehicle bump is punished frequently with slope restorative procedure is connect, draws slope to road point, then milling by starting point of bridge expanssion joint
The former road surface of plane, pave asphalt again.The Treatment Methods are more random, draw the slope gradient and former road gradient coupling compared with
Difference, it is new jump vehicle point to draw slope terminal and existing road surface junction, and this method cannot eliminate Bridgehead-Jumping Disease, only by end of the bridge
Road surface somewhere is moved to after jumping vehicle, i.e., after former Bridgehead-Jumping Disease punishment, asphalt must under the rolling repeatedly of vehicular load
So there is densification phenomenon, easily leads to the generation of secondary vehicle bump.
Therefore, it is punished if bumping at bridge-head in road maintenance engineering can be addressed from Bridgehead-Jumping Disease quantitative description direction
