Abstract: The interaction between vehicle and pavement is complex since pavement roughness excites the dynamic forces generated by vehicles, while these dynamic forces simultaneously increase the pavement roughness. The objective ...

Abstract: When a truck wheel moves on the road, stress pulses develop within the pavement layers. These pulses are primarily functions of load magnitude, tire pressure, and vehicle speed. In this study, dynamic analysis is used to ...

Abstract: An elastodynamic analysis of pavement response to harmonic‐load nondestructive testing is presented. The method is based on a discrete layer approach that assumes linear variation of displacements in the direction of ...

Abstract: A new axisymmetric finite-element pavement-analysis program BIMODPAV capable of accounting for the bimodular nature of the asphalt concrete is developed. The program also considers the nonlinear behavior of the base, ...

Abstract: Curling stresses of concrete pavement can be very damaging, and reducing the temperature swings would be very beneficial. This study includes a field instrumentation effort with pavement temperature sensors to quantify the ...

Abstract: Current failure criteria of asphalt pavements are either empirical or assume linear elastic material response and use a single load level to relate the number of load repetitions to fatigue failure. To better understand ...

Abstract: A project-level optimization approach was developed to minimize total pavement cost within an analysis period. Using this approach, the designer is able to select the optimum initial pavement thickness, overlay thickness, ...
