CMT Laboratory

Construction Materials Testing Capabilities

Construction Materials Testing Services

The construction materials laboratory has increased its capabilities adding to our scope for Aggregate testing.  CMT currently services several quarries in the region with ongoing QA sampling, testing and advice while the environmental group is involved in material assessments.

2015 saw the start of the Bulga Optimisation project.  The project includes:

  • the realignment of 9km of Broke Road allowing coal operations to continue until 2035;
  • new town water main and private irrigation water mains;
  • construction of a 3km internal road;
  • construction of numerous haul roads across the new Broke Road and rail lines.

RCA is the main geotechnical company involved on the Bulga project providing a range of concrete and soil testing for both Daracon Group and Yore contractors as well as geotechnical assessments and advice.  The project is being serviced with the use of high output – automated laboratory compaction machines that improve both report turnaround times for our clients and OH&S for our staff.

RCA has recently completed the Kooragang Islands remediation project. The project involved the remediation of ‘soft soils’ and the construction of a high permeability cap on both the K2 and K10 berths. RCA provided geotechnical testing and advice for the Georgiou group.

Construction Materials Testing

Hunter Expressway Project

RCA Australia has a local team of Geotechnicians and technicians working at our annex laboratory servicing the $1.7 billion Hunter Expressway Project. The Hunter Expressway will provide a 40 kilometre link between the F3 and Branxton.

RCA provides a range of geotechnical testing services for the 27km western section being constructed by Abigroup which reaches from Kurri Kurri to Branxton.

Some of RCA’s testing services include:

  • Nuclear density gauge testing;
  • RTA HILF rapid compactions;
  • Atterberg limits, California Bearing Ratio tests, particle size distributions and unconfined compressive strength testing;
  • Benkelmen Beam deflection testing;
  • Aggregate testing.

This project began in May 2011 and at its peak RCA had approximately 40 staff on site completing up to 1500 tests per week. RCA Project Manager Joe Scully has overseen laboratory operations for this project which is scheduled to end in December 2013.

Maitland to Whittingham Third Track

RCA completed the bulk earthworks testing of Stage 1 of the ‘Maitland to Whittingham Third Track’ project on behalf of the Hunter Alliance.

The project included the bulk earthworks testing for the construction of the third rail track (10 kilometers), and bridge abutments for the Golden Highway and Range Road rail overpasses.

The services provided by RCA included the establishment of an annex (on site) laboratory, bulk earthworks compaction and moisture control testing, soil classification testing, soil bearing strength testing, soil stabilisation testing, and Benkelman beam deflection testing of RTA road pavements.
