LABORATORY EVALUATION OF ASPHALT MIXES CONTAINING VARIOUS PERCENTAGES OF RECYCLED ASPHALT PAVEMENT
Journal Title: ASIAN JOURNAL OF NATURAL & APPLIED SCIENCES - Year 2017, Vol 6, Issue 1
Abstract
Highway authorities around the world are striving to use larger quantities of recycled asphalt pavement (RAP) in order to meet economic and environmental constraints. Widespread road networks are a basis for economic development of any region. RAP use is not only cost effective and environmental friendly, helps in conservation of natural resources and is similar or even better in performance than control asphalt mixtures. This paper presents the experimental study to evaluate the moisture susceptibility of RAP incorporated hot mix asphalt (HMA) using Hamburg Wheel-tracking Device (HWTD). In this research all tested HMAs with RAP showed better performance than the virgin mixes. Mixtures containing RAP showed substantial variability and the variability increased with the increase in RAP content.
