Abstract
The self-healing mechanism of bituminous mixtures was demonstrated through several studies and was recognised for developing sustainable road pavement. This paper presents a comprehensive summary of various studies related to steel fibre as a self-healing mechanism of bituminous materials. Based on the extensive literature, it was found that steel fibre was likely to be used in the asphalt industry due to several benefits. First, the idea of using steel fibre in pavement engineering materials gives great attention to their utilisation in asphalt. It helps increase the self-healing mechanism and contribute to reducing the problem related to potholes, ravelling, slipping during raining while driving and many more. Second, this study identifies the gap of research for future research in pavement engineering. Finally, some proposals were made for the possible construction of self-healing asphalt.
