Aggregate gradation effect on the fatigue performance of recycled asphalt mixtures
Source abstract
Abstract
This paper presents the details of a laboratory study on the evaluation of the fatigue characteristics of asphalt mixtures containing Recycled Asphalt Pavement (RAP) material using controlled stress indirect tensile fatigue test (ITFT). The effect of different aggregate gradations on the fatigue performance of RAP mixes is the main focus of the study as this helps us to identify the proportion of RAP that can be used from fatigue performance consideration. Two dense mixes and three gap graded mixes, both with different percentages of RAP, were investigated. VG 30 viscosity grade virgin binder was used. The fatigue test was conducted at 25°C. Laboratory fatigue life determined under stress controlled mode increased with increase in the RAP content for all the five aggregate gradations. The corresponding ‘Initial strain vs fatigue life’ trends suggest a decrease (for any specific strain level) in the fatigue life with an increase in the RAP content. However, analysis of the fatigue performance of typical pavement sections with different RAP contents do not suggest any significant detrimental effect of increasing the RAP content for pavements with thick bituminous layers. Use of open graded mixes permits the use of larger binder contents and higher RAP contents in the mix. Fatigue lives of RAP mixes are longer for gap graded mixes compared to dense graded mixes. The fatigue lives of RAP mixes are found to correlate very well with fatigue parameters of the virgin-RAP binder blends prepared in suitable proportions.
