Abstract

Abstract

Asphalt–concrete mixtures have various applications in engineering construction projects, with their performance influenced by external, internal, and environmental factors. Several studies have focused on modifying their required properties and performance. Researchers have utilized recycled concrete as an additive or replacement for natural aggregate in asphalt and cement concrete mixtures, yielding acceptable results. This research introduces another waste construction material, porcelain waste, as aggregates replacing recycled concrete aggregates in different proportions to modify the mechanical properties and durability of a binder–asphalt concrete mixture. This is an additional effort to save the environment from different waste construction materials. Following the Marshall requirements, the properties of the samples with optimized quantities were investigated using wheel trucks and Bohme abrasion tests. The modified mixture exhibited an increase in bulk specific gravity by 6% to 2.24, enhanced the Marshall flow from 3.5 to 4.6 mm, and an increase in the stability by 5%, yielding the highest value of 33 kN. Subsequently, the mechanical properties and durability of the mixtures were affected with an increase in the rutting resistance. The highest abrasion resistance and service life were obtained when 25% porcelain replaced the recycled concrete aggregates, but the mixture became more temperature susceptable. Therefore, this study achieved economical, environmentally-friendly, and safe pavements.
