RISConventional, Thermal, and Rheological Properties of Asphalt Binder Modified by Carbon Nanotubes and Crumb Rubber
Publisher: ASCE
Abstract: The purpose of this paper was to investigate the effect of carbon nanotubes (CNTs) and crumb rubber (CR) on the conventional properties, thermal behaviors, and rheological properties of binders. There are four asphalt types ...
Preparation of Emulsified Type Cold-Mix Asphalt with Waterborne Epoxy Resin and Polypropylene Fiber for Pothole Repair
Publisher: ASCE
Abstract: This work addressed the issues of poor bonding and low forming strength of emulsified type cold-mix asphalt (CMA). The aim of this study was to improve the pothole repair effect. Accordingly, waterborne epoxy resin (WER) ...
Conversion from Shear Creep Compliance to Relaxation Modulus of Asphalt Binder Using Cauchy Residue Method and Experimental Validation
Publisher: ASCE
Abstract: The need for conversion between viscoelastic functions arises in that strain-controlled relaxation test is quite difficult to run than a stress-controlled creep test, especially on rigid sample and at low temperatures. A ...
Investigating RAP Dispersion and Its Effect on the Performance of Recycled Hot-Mix Asphalt Mixtures
Publisher: American Society of Civil Engineers
Abstract: The migration of reclaimed asphalt pavement (RAP) mastic into the recycled hot-mix asphalt (RHMA) mixture system during the hot-mix process results in varying dispersion degrees of RAP aggregates within RHMA, impacting its ...
Multiobjective Optimization Model to Coordinate between Segment and Network Level for Managing Pavement and Sustainability
Publisher: ASCE
Abstract: Traditionally, maintenance optimization for large-scale pavement networks usually has been ignored. This study developed a new multiobjective segment-linked decision-making model (MOSL-DM) integrating five modules to ...
Investigation of the Workability, Strength, and Durability of Fiber-Reinforced High-Performance Concrete with Full Aeolian Sand
Publisher: ASCE
Abstract: The application of aeolian sand as the full aggregate to produce high-performance concrete is significant for engineering construction in desert areas. However, high-performance concrete with full aeolian sand (FA-HPC) is ...
Effect of Carbon Nanomaterials on the Rheological Characteristics of Crumb Rubber–Modified Asphalt
Publisher: American Society of Civil Engineers
Abstract: This research aims at studying the effect of graphite nanoplatelets (GNPs) and carbon nanotubes (CNTs) on the rheological characteristics of crumb rubber (CR)–modified asphalt. For this purpose, the apparent viscosity, ...
Research on a Laboratory Technique to Prepare a Rejuvenating Composite Seal and Test Its Long-Term Water Stability
Publisher: ASCE
Abstract: A rejuvenating composite seal (RCS) consists of a chip seal and a micro-surfacing (MS). There are two reasons for RCS’s poor application effect in China and less frequent application than that of MS: first, the material ...
Simulation of Permanent Deformation in High-Modulus Asphalt Pavement Using the Bailey-Norton Creep Law
Publisher: American Society of Civil Engineers
Abstract: The objective of this research is to evaluate the permanent deformation of high-modulus asphalt concrete (HMAC) pavement in terms of the viscoelastic theory. Based on the Bailey-Norton creep law, parameters of HMAC were ...
