PAVEMENT RESPONSE TO ROAD RATER AND AXLE LOADINGS

The response of flexible pavements to 18-kip (80-kN) single axle and Road Rater loadings was investigated. A Benkelman beam was used to measure surface deflection under the axle loading; and a model 400 Road Rater was operated at 25-Hz frequency to monitor pavement deflection. The pavement deflection data were analyzed and the pavement layer moduli were evaluated. The modulus values, in turn, were used to analyze the critical response of the test pavements. Results of the study indicate that, at least for the conditions investigated, summer deflection measurements are as effective as spring season measurements for pavement condition evaluation. The layer modulus values evaluated from the Road Rater deflection basins are not necessarily equal to those obtained from the Benkelman beam deflection basins. Critical pavement response to axle loading can be estimated from the corresponding Road Rater data by using the developed relationships. These relationships and other data may provide a basis for the development of a generally accepted pavement evaluation criterion for use in pavement management programs.
