RISRecycled Concrete Aggregate Modified with Polyvinyl Alcohol and Fly Ash for Concrete Pavement Applications
Publisher: American Society of Civil Engineers
Abstract: Recycled concrete aggregate (RCA) is traditionally limited to nonstructural applications. Although the crushing process results in weak mortar particles and surface cracks throughout the RCA, RCA concrete can be employed ...
Mechanical Properties of Fly Ash–Asphalt Emulsion Geopolymer Stabilized Crushed Rock for Sustainable Pavement Base
Publisher: ASCE
Abstract: Research on the usage of industrial by-products to improve mechanical properties of low-quality materials in infrastructure applications is of global interest. Two industrial by-products, namely, fly ash (FA) and asphalt ...
Mechanical Performance of Porous Asphalt Concrete Incorporating Bottom Ash as Fine Aggregate
Publisher: American Society of Civil Engineers
Abstract: Porous asphalt concrete (PAC) is an open-graded asphalt concrete with a high air void, which functions as permeable pavement with high surface frictional resistance. PAC typically requires a high amount of coarse aggregate ...
Mechanistic Performance of Hybrid Asphalt Concretes with Recycled Aggregates and Hemp Fiber for Low Traffic Roads
Publisher: ASCE
Abstract: The utilization of reclaimed asphalt pavement (RAP) and recycled concrete aggregate (RCA) in road infrastructure construction projects contributes significantly to the sustainable reduction of solid wastes being landfilled. ...
Steady-State Groundwater in Mechanical Stabilized Earth Walls of Various Dimensions with Geocomposite Back Drain Installation
Publisher: ASCE
Abstract: Recently, considerable risks to the internal instability of mechanically stabilized earth (MSE) walls have been encountered from the inadequate drainage capacity of some backfill under extremely heavy rainfall. Due to its ...
Flexural Fatigue Performance of Hemp Fiber–Reinforced Concrete Using Recycled Concrete Aggregates as a Sustainable Rigid Pavement
Publisher: American Society of Civil Engineers
Abstract: This research delved into the mechanical and fatigue attributes of hemp fiber–reinforced concrete (HFRC) using both natural crushed aggregates (NCA) and recycled concrete aggregates (RCA) for sustainable rigid pavements. ...
Mechanistic Performance and Distress Model of Bottom Ash Modified Porous Asphalt Concretes with Various Thailand Aggregates
Publisher: ASCE
Abstract: The porous structure in the porous asphalt concrete (PAC) mixture is achieved by incorporating a substantial amount of coarse aggregate and polymer-modified asphalt binder (PMA). Bottom ash (BA) was used to modify the ...
