review · Key engineering materials
Several attempts have been made on the use of alternative material for constructionpurpose. This is to limit the exploitation of the natural resources and the need to engage onrenewable resources that can function adequately in road construction with minimal carbonfootprints. The main objective of this review is to consider the outcome of the suitability of wasteglass products in the construction of roads based on the existing studies. From the relevant literatureconsulted, it was discovered that waste glass powder has the capacity to improve the compressiveand tensile strength of asphalt mix. Also, it has lower water absorption rate, thereby making itimpossible for the penetration of the chloride ions which usually accelerate road degradation. Inaddition to this, it improves the workability of the concrete used for the pavement construction,hence, it is more advantageous when compared with sand. The findings from this study will help theconstruction industry on the methods of waste glass recycling and its adoption into roadconstruction.
