Asphalt Testing
Laboratory

Innovative Solutions

State Asphalt NSW has been a leader in the testing of asphalt, aggregates, and bitumen for over 50 years. Throughout this time, we have continuously invested in our facilities, optimised processes, and trained our employees to meet the rapidly evolving construction techniques. Our commitment to quality is underscored by our participation in proficiency test schemes for asphalt, aggregate, and bitumen, ensuring a consistently high level of quality and assurance across all our laboratories.

    We have it covered

    State Asphalts NSW is one of the largest independent Asphalt Production businesses in Australia, with production facilities in Prestons, St Marys & South Nowra. Our production facilities have the ability to utilise high recycled content, with multiple feed points for different sustainable materials including RAP (Reclaimed Asphalt Pavement), Glass, Rubber (Tyres) and Fibres (from Coffee Cups). State Asphalts NSW have been awarded grants from federal government, for excellence in continued research into recycling waste materials back into high performance asphalt designs, giving birth to PAK-PAVE, our sustainable product range that utilises waste materials in asphalt production, diverting waste from landfill and largely reducing the use of virgin raw materials.

    St Marys 
    Laboratory

    Our state-of-the-art St Marys lab is NATA accredited. NATA is Australia’s leading national accreditation body, recognised by government to assess an organisations competency against international standards for laboratories, inspection bodies, proficiency testing providers and reference material producers.
