The bituminous pavement rehabilitation alternatives are mainly overlaying, recycling and reconstruction. In the recycling process the material from deteriorated pavement, known as reclaimed asphalt pavement (RAP), is partially or fully reused in fresh construction. Some of the advantages associated with pavement recycling are (i) less user delay (ii) conservation of energy (iii) preservation of...

This paper describes the planning, design and construction of a permeable pavement as a practical demonstration of the benefits of eco-paving in Australian environmental management. The paper addresses the use of permeable pavements as part of a Water Sensitive Urban Design that allows infiltration of stormwater, reduction of pollutants and slow reticulation of the stormwater to an ecologically...

Many rural roadways in Iowa have centerline and/or edgeline pavement markings. The current Manual on Uniform Traffic Control Devices (MUTCD), however, requires centerline and/or edgeline pavement markings only along streets and roadways with traffic volumes much greater than 400 vehicles per day (the volume-based definition of a low-volume roadway in the MUTCD). This project was initiated to ga...

Each of pavements’ life cycle phases such as material extraction, transportation, construction, operation, rehabilitation, and end-of-life emits greenhouse gases. Such emissions can be influenced by climate change via changes in the rates of pavement deterioration and thus intensity and frequency of maintenance and rehabilitation. However, climate change has not been given full considerations i...

The coupling effect between tire and pavement is an intensively researched subject to analyse the dynamic interaction of the vehicle-pavement system. By considering the 11.00 R20 tire and expressway asphalt pavement, ABAQUS software was employed in this study to establish an improved model for simulating the coupling effect, in which the tire rubber was taken as a neoHookean material and the pa...
