RISSmall-Strain Behavior of Cement-Stabilized Recycled Concrete Aggregate in Pavement Base Layers
Publisher: American Society of Civil Engineers
Abstract: A novel approach has been used to simulate the true field performance of cement-stabilized recycled concrete aggregate in pavement bases using a unique, large-scale, fully instrumented pavement model tank (PMT). Vertical ...
Recycled 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 ...

Lightly Stabilized Loose Sands with Alkali-Activated Fly Ash in Deep Mixing Applications
Publisher: ASCE
Abstract: Deep mixing using cementitious compounds are an in-situ ground improvement method for improving the strength and compressibility of loose sands. Low-calcium class F fly ash (FA) is a sustainable low-carbon replacement for ...
Performance and Toxic Leaching Evaluation of Dense-Graded Asphalt Concrete Using Steel Slag as Aggregate
Publisher: ASCE
Abstract: The comparative performance between steel slag (S) and limestone (L) as aggregates in dense-graded asphalt concretes were investigated in this research. The performance tests for fatigue cracking were undertaken using ...
Strength Development and Microfabric Structure of Construction and Demolition Aggregates Stabilized with Fly Ash–Based Geopolymers
Publisher: American Society of Civil Engineers
Abstract: The reuse of recycled construction and demolition (C&D) aggregates in civil engineering infrastructure applications has been considered a low-carbon solution to replace conventional pavement aggregates. Evaluating the ...
Stabilization of Demolition Materials for Pavement Base/Subbase Applications Using Fly Ash and Slag Geopolymers: Laboratory Investigation
Publisher: American Society of Civil Engineers
Abstract: The use of recycled construction and demolition (C&D) materials in unbound and cement stabilized pavement base/subbase applications has generated growing interest in recent years. C&D materials consisting of crushed brick ...
Laboratory Evaluation of the Use of Cement-Treated Construction and Demolition Materials in Pavement Base and Subbase Applications
Publisher: American Society of Civil Engineers
Abstract: Construction and demolition (C&D) materials constitute a major proportion of waste materials present in landfills worldwide. With the scarcity of high-quality quarry aggregates, alternative materials, such as C&D materials, ...
