چکیده

Recycling of asphalt concrete is increasingly used as a major rehabilitation method in Japan because it can conserve natural resources, reduce costs and save energy. In this study, reclaimed asphalt concrete from Tokyo International Airport was evaluated for use in four types of base materials: recycled granular material, recycled cement stabilized material, recycled cement-emulsified asphalt stabilized material and recycled hot-asphalt stabilized material. The results of laboratory tests indicated: 1) These materials can satisfy base course and subbase requirements, and 2) they are sensitive to temperature and water.

Evaluating the Performance of Hot Mix Asphalt with Reclaimed Asphalt Pavement and Heavy Vacuum Slops as Rejuvenator

Due to the high price of crude oil, and consequently asphalt binder, the application of Reclaimed Asphalt Pavement (RAP) in pavement technology is widely considered. The present paper is the result of a laboratory research which was carried out to investigate the effects of adding a rejuvenating agent to Hot Mix Asphalt (HMA) with RAP. To this end, test samples comprised of Aged Asphalt Binder ...

Effect of Reclaimed rubber Modification on the Rheological Properties and Rutting Resistance of Asphalt Binders

In this paper, the effect of reclaimed rubber modification on the rheological characteristics of asphalt binders is studied. Reclaimed rubber with the extent of 12, 16 and 20 is added to the neat asphalt binder and then shear complex modulus is obtained for neat and modified asphalt binder via Dynamic Shear Rheometer (DSR) test. Using Christensen-Anderson- Marasteanu (CAM) model, master curves ...

Evaluation of Fatigue Properties of Asphalt Mixtures Containing Reclaimed Asphalt using Response Surface Method

This paper presents the effects of different amounts of reclaimed asphalt on fatigue life of asphalt mixtures. Central composite method was used to design of experiments based on response surface method (RSM). Binder type (Pen 60/70 and Pen 85/100), reclaimed asphalt pavement (RAP) content (25, 50 and 75%) and loading strain (150, 250 and 350 micro strain) were selected as independent variables...

Modeling of Resilient Modulus of Asphalt Concrete Containing Reclaimed Asphalt Pavement using Feed-Forward and Generalized Regression Neural Networks

Reclaimed asphalt pavement (RAP) is one of the waste materials that highway agencies promote to use in new construction or rehabilitation of highways pavement. Since the use of RAP can affect the resilient modulus and other structural properties of flexible pavement layers, this paper aims to employ two different artificial neural network (ANN) models for modeling and evaluating the effects of ...
