dc.description.abstract | Asphalt mixtures are often regarded as the most popular type of surfacing material used in roadway development. However, in recent years there has been an increase in pavement failures in asphalt roadways. Countries such as South Africa, in particular, are experiencing the severe hindrance of these damaged roadways, which lead to numerous socio-economic issues. The determination of the current state, of the study, of the use of non-conventional materials in asphalt as well as understanding if the industry is ready and willing to consider the use of these modified asphalt mixes. This allows researchers to consider new and innovative ways for further research on this imperative topic, as well as accelerating the process of the civil engineering industry implementing modified asphalt mixtures into the development of several new infrastructures. The study aims to determine if the civil engineering industry will consider using various types of non-conventional materials in asphalt mixtures to improve the roadways’ overall performance capabilities. The study uses the quantitative survey method to gather crucial information. The target group selected for the survey consisted of individuals, particularly in the asphalt industry, who either contribute or contain knowledge on non-conventional materials or developing modified or traditional asphalt mixtures. The survey was carried out through a questionnaire developed using Google Forms to reach a considerable number of individuals in the target group. The results highlighted interest from the industry; however, there is still scepticism regarding the viability of incorporating non-conventional material in the asphalt mixtures, illustrating a potential for further development in this research area to be accomplished. | |
