RISFormulation of a New Rejuvenator and Its Regenerative Effect on Aged Asphalt
Publisher: ASCE
Abstract: A massive amount of recycled asphalt pavement (RAP) is produced in road construction and maintenance, and using rejuvenators to rejuvenate RAP can have a significant economic benefit. At present, a biorejuvenator is used ...
Preparation and Performance Characterization of Phosphogypsum Whisker Composite Modified Asphalt Binder
Publisher: American Society of Civil Engineers
Abstract: Solid waste recycling and reuse have attracted great interest as environmentally friendly modifiers for asphalt pavements in recent years, and phosphogypsum whiskers (PSWs) synthesized by phosphogypsum (PSP) wastes were ...
Multilayer Microstructure Characterization of the Interfacial Transition Zone between Polymer-Modified Magnesium Phosphate Cement and Portland Cement
Publisher: ASCE
Abstract: Magnesium phosphate cement (MPC) as a fast-setting material has been widely used in the rapid repair of cement concrete pavement. A decisive role was played in the bonding performance of the repair interface between MPC ...
Experimental Study on a Novel Modified Magnesium Phosphate Cement Mortar Used for Rapid Repair of Portland Cement Concrete Pavement in Seasonally Frozen Areas
Publisher: ASCE
Abstract: In this study, basalt fiber-reinforced and polymer-modified magnesium phosphate cement (BFPMPC) mortar, a novel rapid repair material, is proposed for portland cement concrete pavements (PCCP). A practical mixture design ...
Comparative Study on High-Temperature Performance of MPC and BFPMPC
Publisher: ASCE
Abstract: Because a new magnesium phosphate cement (MPC) developed previously for the rapid repair of cement concrete structures has better mechanical properties and bonding properties, the high-temperature properties were further ...
Experimental Investigation on the Properties of Vulcanized Natural Rubber–Modified Asphalt Binder
Publisher: ASCE
Abstract: With the huge production of natural rubber (NR), it is feasible to produce natural rubber–modified asphalt binder (NRMB) to achieve carbon neutrality and environmental sustainability in asphalt pavement construction. As a ...
Damage Mechanism of Asphalt Binder Modified with Phosphogypsum Whisker Composite under the Action of Sea Salt Solution
Publisher: American Society of Civil Engineers
Abstract: The study of the reaction mechanism of sea salt solution (SSS) on asphalt binder was important for the development of perpetual asphalt pavements in coastal areas. For this, a novel modifier (MPGJ-I) was developed in this ...
Three-Dimensional Micromechanical Complex-Modulus Prediction of Asphalt Concrete Considering the Aggregate Interlocking Effect
Publisher: American Society of Civil Engineers
Abstract: The complex modulus (E*) is a fundamental material property extensively used for characterizing the viscoelastic behavior of asphalt concrete. In recent years, numerous micromechanics-based models have been proposed for ...
Effect of Water Content on Volumetric and Mechanical Properties of Cement Bitumen Emulsion Mixture
Publisher: American Society of Civil Engineers
Abstract: Water greatly affects the mechanical properties of cement bitumen emulsion mixture (CBEM). Its content is usually determined by the minimum voids content of CBEM. However, its effect on the mechanical properties of CBEM ...
