RISUse of Limited Experimental Data for the Prediction of Creep and Recovery of Asphalt Binders
Publisher: ASCE
Abstract: Prediction of creep and recovery of asphalt binders using limited experimental data can reduce instrumental stress and save time. A simple methodology, using generalized Burger’s model (GBM) and time temperature superposition ...
New Damage Parameter for Fatigue Analysis of Asphalt Binders in Linear Amplitude Sweep Test
Publisher: ASCE
Abstract: The fatigue resistance of two conventional and two polymer modified binders using a new definition of failure in the linear amplitude sweep (LAS) test was assessed in this study. Viscoelastic continuum damage (VECD) theory ...
Evaluating the Suitability of Nanoclay-Modified Asphalt Binders from 10°C to 70°C
Publisher: ASCE
Abstract: This study presents the results of laboratory experiments and analyses carried out to evaluate the rheological performance of nanoclay (NC) modified asphalt binders from 10°C to 70°C. A viscosity graded binder, VG-30, was ...
Effective Technique to Estimate Cross Model Parameters
Publisher: American Society of Civil Engineers
Abstract: The Cross model has been successfully used for modeling the shear thinning behavior of asphalt binders. Usually minimization of least squares/absolute error is used for obtaining model parameters. The curve fitted using ...
Analysis of Different Test Methods for Quantifying Rutting Susceptibility of Asphalt Binders
Publisher: American Society of Civil Engineers
Abstract: Various rutting susceptibility parameters for unmodified and modified bitumen were studied at three different temperatures of 40, 50, and 60°C. Wheel rut testing was also conducted on three different bituminous mixes at ...

Effect of Nanoclay on Physical and Rheological Properties of Waste Cooking Oil–Modified Asphalt Binder
Publisher: ASCE
Abstract: The use of waste cooking oil (WCO) and nanoclay (NC) in the modification of asphalt binder can produce sustainable material for paving applications. This study evaluated the change in physical and rheological properties ...
Development of the Criteria for Optimum Filler–Binder Ratio in an Asphalt Mix Based on Fatigue Performance
Publisher: American Society of Civil Engineers
Abstract: This research aims to propose a framework for selecting the optimum filler–binder (F-B) ratio in an asphalt mixture, with the objective to achieve desired fatigue performance at the lowest possible binder content. The ...
Use of Recycled Waste Plastic for Wet Modification of Bitumen
Publisher: American Society of Civil Engineers
Abstract: This research delved into the pivotal factors influencing the production of recycled waste plastic (RWP)-modified bitumen using a wet modification process. Two types of RWP, namely, low-density polyethylene (LDPE) and ...
