Abstract

subgrade particles acceleration on flexible pavement was investigated and is explained in order to obtain the comprehensive understanding about pavement. Investigation was conducted in the highway which has a yearly construction problem. The data collected from field investigation represents the correlation between soil particles acceleration (a) depends to time (t) in three axis main principal direction (x, y and z axis) movements. The main objective of this work is to evaluating the effects of vehicle traverse on the pavement to several parameters, such as soil particles acceleration and the thickness of subgrade. The results revealed that the soil particles acceleration due to of motorcycles traversers loading recorded at 0.0002 – 0.0005 m/s2 . Furthermore, due to of car and truck loading traverses are 0.0006 – 0.00085 m/s2 and 0.0012 – 0.0045 m/s2 respectively. The subgrade thickness has an influenced on the level of soil particles accelerations. Soil particles acceleration in the middle of subgrade reaches the maximum value for both types of vehicles
