Influence of Crumb Rubber and Coconut Coir on Strength and Durability Characteristics of Interlocking Paving Blocks

Interlocking Paving Blocks (IPB) are, nowadays, a widely used construction material. As result of the surge in demand for IPBs, alternative materials have been investigated to be IPBs. This study strength and durability characteristics (compressive strength, split tensile density, water absorption, skid resistance, abrasion resistance) IPBs presence (waste materials) crumb rubber (CR) coconut coir fibers (CCF). Both compressive increased CCF certain extent. CR-based showcased an increase resistance that satisfied both SLS 1425 BS EN 1338 specifications. Abrasion depths CCF-based samples show comparable values when respective fraction (CR or CCF) increases. Therefore, this research fills knowledge gap, highlighting importance incorporating waste IPB industry rather than open dumping.
