PREDICTION OF RUTTING IN VIRGIN AND RECYCLED ASPHALT ...

This paper summarizes the results obtained from a research project carried out to evaluate the rutting performance of recycled asphalt concrete subjected to repeated loading. In order to characterize the rutting behavior, exact stress conditions that occur in the field were simulated in the laboratory using repeated load triaxial tests. Several modifications were carried out on the ...

Rutting performance prediction of warm mix asphalt ...

25-10-2017  To assess the impact of RAP on rutting properties of hot mix asphalt, mixtures were tested using Marshall and dynamic creep tests. It was found that replacing up to 60% of the virgin aggregate with RAP improved rutting properties of the asphalt mixtures because RAP increased asphalt binder's viscosity as a main factor of rutting, especially at high temperatures.

Development of a rutting prediction model for asphalt ...

Integrating the design of a pavement structure and its materials is fundamental to ensure that asphalt pavements possess adequate rutting resistance. In this study, a rutting prediction model was established to link mixture permanent deformation with pavement rutting in the process of integrating design. Several factors, such as the application environment (temperature and vehicle speed ...

The utilization of waste polyethylene terephthalate (WPET) as aggregate substitutes in pavement has been extensively promoted because of its environmental advantages. However, previous studies have shown that a high percentage of WPET reduces the performance of the pavement. To increase the durability of pavement and mitigate the environmental issues caused by WPET, WPET is treated with

Evaluation of the Blending Effectiveness of Reclaimed ...

There is a recent trend of using a higher content of reclaimed asphalt pavement (RAP) in asphalt pavement construction. When evaluating the properties of mixed RAP and virgin binder and selecting a base binder to be mixed with a high-RAP mix using a blending chart, the effect of partial blending is sometimes neglected and total blending is assumed.
