TL;DR: In this paper, an extensive series of repeated load triaxial tests performed on three major recycled construction and demolition (C&D) materials at various moisture contents and stress levels were analyzed to ascertain their performance in pavement subbases.

TL;DR: In this paper, the use of fly ash (FA) and slag (S) as alternative green binders in ground-improvement projects that would reduce the carbon footprint of these projects was investigated.

TL;DR: In this paper, an extensive suite of engineering and environmental tests were undertaken on steel slag aggregates to evaluate their potential usage as road construction materials, including particle size distribution, hydrometer, organic content, flakiness index, Atterberg limits, particle density, water absorption, pH, minimum and maximum dry densities with a vibrating table, modified compaction, California bearing ratio (CBR) and Los Angeles abrasion tests.

TL;DR: Fly Ash (FA), an abundant by-product with no carbon footprint, is a potential stabilizer for enhancing the physical and geotechnical properties of pavement aggregates and testing indicated that FA was a viable binder for the stabilization of recycled CB and RAP.

TL;DR: The types, properties, and applications of different fibres used in a wide range of materials in the construction industry, including concrete, asphalt concrete, soil, earth materials, blocks and bricks, composites, and other applications are reviewed.
