RISEvaluation of Rejuvenated Aged-Asphalt Binder by Waste-Cooking Oil with Secondary Aging Considered
Publisher: ASCE
Abstract: Waste-cooking oil (WCO) has received significant attention regarding rejuvenating aged-asphalt binder (AB) in recent years. Most current studies focused on whether the performance of WCO rejuvenated aged-asphalt binder ...
Micromechanical Model for Predicting Coefficient of Thermal Expansion of Concrete
Publisher: American Society of Civil Engineers
Abstract: Thermal cracking of Portland cement concrete (PCC) decreases rideability and accelerates deterioration of concrete pavements. Coefficient of thermal expansion (CTE) is one of the most important parameters to evaluate the ...
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 ...
Deterioration of Cold Recycled Mixtures Using Foamed Asphalt in Seasonal Frozen Region
Publisher: ASCE
Abstract: The cold recycled mixtures using foamed asphalt (CRMF) has been widely used in pavement construction with many ecofriendly advantages. However, the material with a large void fraction is more vulnerable to freeze-thaw ...
Shedding Light on the Rejuvenation Mechanism of Reactive Compounds in Aged SBS-Modified Asphalt through Molecular Dynamics and Quantum Chemical Simulations
Publisher: American Society of Civil Engineers
Abstract: The purpose of this study is to address the problem of reconstructing damaged styrene–butadiene–styrene (SBS) molecular structures in order to facilitate the effective recycling of aged SBS-modified asphalt (SBSMA). ...
Validating MEPDG with Tennessee Pavement Performance Data
Publisher: American Society of Civil Engineers
Abstract: To implement the Mechanistic-Empirical Pavement Design Guide (MEPDG) developed by AASHTO for pavement construction and rehabilitation, it is necessary to evaluate its performance prediction models using actual pavement ...
Investigation on Top-Down Cracking on Two-Lift Concrete Pavement under Freeze–Thaw Environment
Publisher: ASCE
Abstract: Top-down (TD) cracking is the main concrete pavement cracking type in seasonal frozen areas. A two-lift concrete (2LC) pavement, including a polypropylene fiber reinforced concrete (PFRC) top lift and a portland cement ...
