EVALUATING THE MECHANICAL PROPERTIES OF POROUS PAVEMENTS WITH ALCCOFINES AND ALKALI-ACTIVATED GGBS

Abstract

The construction industry faces significant challenges in balancing performance, sustainability, and environmental impact in pavement systems. Traditional porous pavements, while effective in enhancing drainage and reducing urban heat islands, often struggle with issues r elated to durability and environmental footprint. Recent advances in alternative materials such as alccofines and alkali activated ground granulated blast furnace slag (GGBS) offer promising solutions but have not been extensively studied in the context of porous pavements. This study aims to address these challenges by integrating alccofines and alkali activated GGBS into porous pavement systems, assessing their combined effects on performance and sustainability. A series of experimental investigations wer e conducted to evaluate the impact of incorporating various proportions of alccofines and alkali activated GGBS in porous pavement mixtures. Key performance metrics such as permeability, compressive strength, durability, and environmental impact were syste matically analysed.
