Abstract. The major purpose of this study was to address the challenge of managing solid waste by assessing the compatibility of waste plastic-modified asphalt-rubber binders through rheological and morphological analyses. Blending operations incorporated varying proportions of crumb rubber (CR) and polyethylene terephthalate (PET) into the base asphalt binder covering six different...
Abstract. The use of Reclaimed Rubberised Asphalt Mixtures (RRAM) in road pavement construction is a significant stride in reducing reliance on new materials and reducing waste disposal. RRAM provides a sustainable, cost-effective solution for roads, boosting durability and performance while supporting environmental causes [1,2]. However, despite its benefits, challenges remain. A thorough...
Abstract. This study was conducted to assess the time evolution of the lin-ear viscoelastic behaviour of bituminous mixtures containing crumb rubber added by dry process. For this purpose, three mixtures containing 0% or 4% of rubber and with neat 35/50 pen grade or SBS-modified bitumen were manufactured and stored for 15 months before being subjected to complex modulus tests. The results were...
Abstract. Asphalt-rubber can be produced following three main types of methods: the “wet method”, the “dry method” and the more recent “semi-wet” method, each one with their own variations. As long as an adequate technical and economical assessment is performed, these methods of as-phalt-rubber production might have their own space, as they have different costs and specific equipment demands...
Abstract. Fourier Transform Infrared Spectroscopy (FTIR) has emerged as a powerful tool for evaluating the performance of asphalt binders. Its ability to analyze both the chemical composition and molecular structure of mate-rials provides essential insights into the changes that occur during the bi-tumen modification process. A key area of application is the investigation of shared components...
Abstract. The asphalt rubber wet process is a practical means of providing environmental, economic, sustainable, and safety of using crumb rubber from recycled tires using the wet method technology widely used in societal benefits. New imaginative and innovative engineering technology concepts have led to the development of a new asphalt rubber, crumb rubber semi wet method material with...
