Toll roads have contributed in serving the community , monitoring and analysis of vertical and horizontal deformation are required , they are affected by the increasing amount of traffic volume , exceeded capacity of truck load , pavement due to chemical reactions , and inspection and maintenance that does not meet the standard(unspecified inspection and maintenance).The main purpose of monito…

Backcalculation of FWD data often results in unrealistic layer moduli. The modulus of the subgrade may be two to three times the expected value, and the modulus of an intermediate granular material may be lower than the subgrade modulus. If stresses or strains measured in the pavement are compared with theoretical values, the agreement is often poor. All theoretical models for calculating pa…
