ABSTRACT
ABSTRACT: There is a correlation between pavement deflection level and axle load. Generally, it has been accepted that the exponential relationship exists between deflection ratio and axle load, and the exponent b is the important parameter during axle load conversion. Based on dynamic and static tests on-site and statistical analyses, the calculation method as well as the recommended “b” value has been developed under over-load situation, which is also the basis of establishing specifications.
