As the Framework Act on Sustainable Infrastructure Management has recently been enacted in Korea, it become mandatory to establish a medium-and long-term plan for managing social infrastructure and evaluating feasibility of maintenance projects. However, road agencies are experiencing problems due lack deterioration models which essential conducting life cycle cost analysis. Thus, this study de...

This study presents a finite element (FE) micromechanical modelling approach for the simulation of linear and damage-coupled viscoelastic behaviour of asphalt mixture. Asphalt mixture is a composite material of graded aggregates bound with mastic (asphalt and fine aggregates). The microstructural model of asphalt mixture incorporates an equivalent lattice network structure whereby intergranular...

This study investigated the effect of high asphalt binder replacement for a low N-design asphalt mixture including RAP and RAS on performance indicators such as permanent deformation, fracture, fatigue potentials, and stiffness, was studied. An experimental program included complex modulus, fracture, overlay reflective cracking resistance, wheel track permanent deformations, and push-pull fatig...

Using Reclaimed Asphalt Pavement (RAP) in asphalt mixes has become a common practice in many countries as experience indicated that the recycling of asphalt pavements is very advantageous from different perspectives. Some of the advantages of utilizing RAP include conservation of asphalt and aggregate resources, conservation of energy, and reduction in life-cycle cost. In this study, the suitab...

In general, acid aggregates are not used in combination with asphalt concrete because of their poor compatibility the binder, which typically results a scarce water stability concrete. present study, feasibility new approach based on granite fine aggregate alkaline limestone coarse and Portland cement filler has been assessed. The mineral chemical compositions these three materials have first a...
