Pavements are constructed to deteriorate because of many factors such as traffic loading, material related factors, climate, and other environmental factors. In order to preserve these investments, a maintenance program should be carried out at right time and right places. One of the most important maintenance activities is asphalt overlays. Designing an overlay is more challenging since it res...

Abstract Semi-flexible pavement has a more notable advantage over asphalt concrete in terms of rutting performance. Cement grouting and open-graded are components the semi-flexible pavement. In cement grouting, two commercial modifiers from Sika Vietnam were used, Latex TH Latex, with different contents 4.5% to 7.5% for 9.5% Latex. 72 samples mortar fabricated laboratory conditions PCB40. All g...

Reduction in vehicle fuel consumption is one of the main benefits considered in technical and economic evaluations of road improvements considering its significance. Surface roughness, texture, and structural response are the main pavement characteristics influencing rolling resistance. This project investigates the increase in vehicle energy consumption caused by the structural response of a c...

This paper introduces a new concept of integrating artificial neural networks (ANN) and genetic algorithms (GA) in modeling the deflection basins measured on the flexible pavements. Backcalculating pavement layer moduli are well-accepted procedures for the evaluation of the structural capacity of pavements. The ultimate aim of the backcalculation process from Nondestructive Testing (NDT) result...
