Abstract

The number of scrap tyre generated every year has reached an alarming state due to the rapid development of roadway and high demand in transportation vehicles. Since the scrap tyre rubber is not biodegradable, this will create severe negative impacts to the environment in term on air, water and soil pollution. In order to minimize this massive number of scrap tyre, they need to be recycled and reclaimed to form new product such as asphalt component. Based on the past researches, the usage of recycle tyre rubber has been proven workable to be used in asphalt road pavement industry. Therefore, this research aimed to modify the conventional bituminous mixes by using recycle tyre rubber as a partial replacement to fine aggregate, hoping that a better mixes will be produced and perform better than the conventional mix design. An investigation was conducted by using PEN 60/70 on a range of ACW 14 to investigate the effect of utilization of recycle tyre rubber as a partial fine aggregate replacement of size 0.425mm in ACW 14 mixtures. Total number of 15 samples of control specimens and 27 samples for modified specimens have been prepared. Replacement of fine aggregate by recycle tyre rubber has been set to 12.5%, 25% and 50% in order to test the optimum recycle tyre rubber content for the mix design. Marshall results obtained for both the standard and modified bituminous mixes were found to be in agreement with the specifications prescribed by JKR. The optimum recycle tyre rubber content obtained through this experiment is 12.5% with 75 blows of compaction. From the results, it can be concluded that recycle tyre rubber has performed exceptionally well under the tests needed to confirm for its utilization as fine aggregate replacement materials in ACW 14 and it will shift gears to sustainable pavement construction.
