Testing labs in South Windsor, NSW

Hawkesbury Eco Asphalt Pty Ltd is an independent asphalt testing facility and manufacturer located in South Windsor, New South Wales, Australia. Operating since 2020, the company specializes in quality assurance and laboratory testing services for the road construction and civil engineering industries. With an integrated testing laboratory and asphalt batching plant, the facility serves contractors, engineers, and government agencies across Australia who require rigorous asphalt and aggregate analysis for infrastructure projects. The laboratory is NATA accredited (Accreditation No. 20717, Site No. 24859) under ISO/IEC 17025:2017, the international standard for testing and calibration laboratory competence. This accreditation certifies the facility's technical competence and quality systems for infrastructure and asset integrity testing, providing assurance to clients that all testing is performed by qualified personnel using validated methods. The company is registered as a supplier with NSW Government procurement (buy.nsw.gov.au), demonstrating compliance with public sector contracting requirements. Hawkesbury Eco Asphalt provides comprehensive asphalt testing and quality control services essential for infrastructure projects. Testing capabilities include bitumen content and aggregate grading analysis using reflux methodology, particle size distribution via sieve analysis (AS 1141.11.1), field density measurements using nuclear gauge equipment, moisture content assessment, and volumetric properties analysis including bulk density, maximum density, and voids determination. The laboratory also offers specimen manufacturing with proper conditioning and compaction, as well as sample collection services including asphalt core extraction (both dry and wet techniques), loose asphalt sampling, and aggregate extraction from stockpiles. The facility utilizes modern equipment and industry-standard testing methods in accordance with Australian asphalt standards. Nuclear gauge equipment enables non-destructive field density testing, while laboratory analysis incorporates sieve analysis, reflux methodology for bitumen extraction, and core drilling techniques. All testing is performed by qualified technicians following ISO 17025-accredited procedures, ensuring reliable and defensible results for quality verification, specifications compliance, and regulatory reporting. Hawkesbury Eco Asphalt primarily serves the construction and civil engineering sectors, including asphalt and pavement contractors, civil engineers managing infrastructure projects, waste and recycling companies processing recycled asphalt pavement, and government agencies requiring certified testing for public works. The company's expertise in both virgin and recycled asphalt testing makes it a valuable partner for sustainability-focused projects and contractors seeking to verify material specifications before placement. The facility's location in the Hawkesbury region of NSW positions it strategically to serve projects across the greater Sydney metropolitan area and regional New South Wales. The laboratory's sample types include asphalt cores extracted from in-service pavement, bulk loose asphalt specimens, virgin and recycled aggregates from stockpiles, and recycled asphalt pavement (RAP) materials. The facility's dual-technique extraction capability (dry and wet methods for core recovery) allows flexibility in sample collection for different project conditions and requirements. This breadth of testing ensures that Hawkesbury Eco Asphalt can support contractors and engineers through all phases of asphalt quality assurance—from material specification verification through production quality control and in-situ field testing of completed pavements.
