Pavement Crack Treatment: Feasibility Study on using Plastic Waste ss Sealant

Abstract

This study focused on the plastic waste ability to be one of the materials as a sealant dealing with an early pavement deterioration. By identifying the current materials or technology used as a crack sealant, it would be beneficial to researchers and engineers to get more precise detail and understanding of the plastic criteria similarity with existing material used as a crack sealant. The objectives of this study are to benchmark the current trend of material or technology used as a sealant for pavement crack treatment, to determine the factors affecting or criteria of a good material used as a crack sealant, to compare the plastic criteria similarity with existing material used as a crack sealant, and to determine the public acceptance and feedback regarding plastic waste usage as a crack sealant in Malaysia. Information was gathered from past research via a comprehensive literature review. The questionnaire survey was disseminated to gather feedback regarding the demographic profile, awareness of plastic waste, road pavement defects, and feasibility of plastic as a crack sealant. The gaps analysis has found that the plastic material fulfills most of the criteria as rubberised material except the elasticity. This feasibility study received the three (3) highest agreeable criteria from Civil engineers and the general public, that the early pavement treatment is necessary, their interest in exploring plastics waste as a crack sealant, and the workability of plastics waste as a sealant for pavement crack treatment. Further in-depth study and proof of concept (POC) are suggested to be conducted in the future.
