RISEvaluating Factors Affecting Aggregate-Bitumen Interfacial Strength Using Binder Bond-Strength Test
Publisher: ASCE
Abstract: The present study evaluated the effects of six different bitumen film thicknesses (0, 0.2, 0.4, 0.6, 0.8, and 1 mm); four polishing levels of aggregate [220, 400, 600, and 800 Silicon Carbide (SiC)]; three moisture ...
Comparison of Rutting Resistance of Plant Produced Asphalt Mixes Using Hamburg Wheel Tracker and Surrogate Simple Performance Tests: IDEAL-RT and HT-IDT
Publisher: ASCE
Abstract: The recent emphasis on adopting the balanced mix design (BMD) concept has encouraged highway agencies and practitioners to explore simple performance tests to capture the rutting performance of asphalt mixes. Though many ...
Novel Approach to Characterize Moisture Damage in Asphalt Mixtures Based on Critical Permeability
Publisher: ASCE
Abstract: Moisture damage resistance assessment in asphalt mixtures traditionally relies on the tensile strength ratio (TSR) method, which may not capture the complex behavior of asphalt under moisture ingress. This study proposes ...
Comparison of Shape Parameters and Laboratory Performance of Coarse Aggregates Produced from Different Types of Crushing Operations
Publisher: American Society of Civil Engineers
Abstract: The current study compared aggregate shape parameters and laboratory performance of coarse aggregates produced from two different types of crushing operations. The coarse aggregates from two type of crushing operations, ...

Publisher: American Society of Civil Engineers
Rheological Interference of Amine and Silane–Based Antistripping Agents on Crumb Rubber–Modified Binder
Publisher: ASCE
Abstract: Liquid antistripping agents are added to asphalt binder to improve moisture resistance of the mixture. However, the chemical makeup and bonding mechanism of antistripping agents may cause significant effects on binder ...
Stiffness Behavior and Micromechanical Modeling of Asphalt Mastic Composed of Different Fillers
Publisher: ASCE
Abstract: Fillers are known as dust fractions in asphalt mixes having a predominant particle size less than 75 micrometer (μm). Typical filler concentration in an asphalt mix varies from 4% to 12% (by aggregate weight). The effects ...
Effect of Different Long-Term Aging Conditions on Cracking Resistance of Polymer-Modified Asphalt Binder and Mixes
Publisher: ASCE
Abstract: Long-term aging of asphalt binder plays a major role in fatigue cracking resistance of asphalt mixes. With the use of polymer-modified binder (PMB) with different polymer concentrations, aging susceptibility of asphalt ...
Rutting and Cracking Performance of Asphalt Mixtures for 150 mm and 100 mm Diameter Samples Using Simple Performance Tests
Publisher: American Society of Civil Engineers
Abstract: The balanced mix design (BMD) approach has emphasized the implementation of simple performance tests such as the indirect tensile asphalt cracking test (IDEAL-CT) and ideal rutting test (IDEAL-RT) for evaluating cracking ...
High- and Intermediate-Temperature Performance of Asphalt Binder Containing Carbon Nanotube Using Different Rheological Approaches
Publisher: American Society of Civil Engineers
Abstract: The present research work was undertaken to evaluate the rutting performance of carbon nanotube (CNT)–modified asphalt binders. Additionally, intermediate-temperature performance, aging resistivity potential, and ...
