Pavement Engineering Case Study for Reid Alexander Interchange

This case study outlines the pavement engineering services provided by SGS for the Reid Alexander Interchange project in Australia, awarded by Abigroup in May 2011. The project involves the construction of an interchange at Reid Highway and Alexander Drive, aimed at improving traffic flow and safety. SGS was selected for its expertise in conducting periodic pavement surveys to assess the performance of the newly constructed highway. The study details the methodologies employed by SGS, including measuring rideability and roughness properties, using advanced equipment such as the digital multi-laser profilometer and British Pendulum Tester for skid resistance. SGS's role includes ongoing assessments at one year, three years, and a final survey seven years post-construction to ensure compliance with national and international standards. The case study emphasizes the importance of thorough inspections and testing to maintain quality and safety standards in modern highway construction.
