Recent development in automobile sector has increased the use of car as the main mode of transportation thus tremendously boosted tyres production. This situation has led to generation of massive stockpiles of used tyres which resulted in uncountable environmental implications since they are non-biodegradable. Therefore, this study is conducted aiming to recycle used tyres in the form of crumb rubber by producing a prototype noise barrier wall which used crumb rubber as the filler. The experimental study focused primarily on the capability of the crumb rubber noise barrier wall to reduce noise. The methodologies adopted in this study consist of four stages. First, field investigation was conducted to obtain the average traffic noise and noise reduction value. Then, sieve analysis was carried out to determine the percentage of crumb rubber passing sieve no. 3.35 mm and 600 }un as these sizes will be used as filler in the noise barrier wall. Next, a prototype noise barrier wall of dimension 1200 mm x 1000 mm was constructed in a laboratory using hollow concrete blocks. The crumb rubber noise barrier wall was built in four different arrangements to see the differences of noise reduction value between noise barrier wall with and without side wall, noise barrier wall with and without crumb rubber filler and noise barrier wall with sealed and unsealed joints. After that, sound reduction testing was conducted for each arrangement. The results obtained indicated that different arrangements yielded different noise levels. More importantly, the results proved that crumb rubber do has potential in absorbing noise. In the end of the study, it can be concluded that crumb rubber could be used as filler for noise barrier wall to reduce traffic noise as it is capable of absorbing noise.
