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 ...
متن کاملEvaluation 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...
متن کاملDesign and Performance of Hot Mix Asphalts with High Percentages of Reclaimed Asphalt: Approach Followed in the Paramix Project
The use of reclaimed asphalt pavement (RA) in new asphalt pavements can provide important economical savings, while reducing the negative environmental impact. The European research project PARAMIX aims to improve the techniques for hot mix recycling in plant and cold mix in situ recycling, so as to increase the amount of reclaimed asphalt and develop competitive road pavement rehabilitation te...
متن کاملEvaluating 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 ...
متن کاملInvestigating the Performance Characteristics of Asphaltic Concrete Containing Nano-Silica
Using nano-technology materials in the asphalt pavement industry is new compared with Portland cement concrete. The main objective of this study is to investigate the effects of nano-silica modification on some properties of a penetration grade asphalt cement and a typical asphalt concrete. 60/70 penetration grade bitumen was modified with different percentages of nano-silica (i.e. 1, 3 and 5%,...
