Dynamic Loads Caused By Uneven Pavement Research, And Its Damaging Effects On The Road

The dynamic loads cused by roughness pavement is commonplace, which is the main reason of initial damage of pavement and affects the normal usage of pavement. In order to comprehend the characteristics of permanents deformations under dynamic loads and build the reliable base of pavement design. The vehicle and road decoupled vibration caused by unrughness is theorist analyzed and suggests the formulation of dynamic loads calculations and characteristic of dynamic loads in the paper.In the paper suggests the prediction model under dynamic loads after combining permanent deformation prediction and evaluation in country and overseas, the suggesting prediction model is proved reliable by analyzing an example.
