Construction of a high modulus asphalt (HiMA) trial section Ethekwini: South Africa's first practical experience with design, manufacturing and paving of HiMA

Abstract

A trial section was paved with the recently introduced High Modulus Asphalt (HiMA) technology on South Coast road in eThekwini (Durban). The trial section forms part of an effort to transfer HiMA technology to South Africa, in an initiative aimed at increasing the options available for the design of heavily trafficked pavements. Apart from rehabilitation of the road, the aim of the project was to monitor the performance of the innovative pavement material. The project is the first full implementation of the technology and follows the development of the preliminary mix design and structural guidelines for HiMA.
