Hunter Civilab specialise in concrete testing, offering a range of services and test types, as well as project compliance testing to RMS & AS specifications.
Determines the difference in pH of the natural soil vs that with Hydrogen Peroxide. Used in the assessment of Acid Sulphate Soils.
The Roof Rolling Test is a standard test method used to evaluate the adhesion, cohesion, and other physical properties of roofing materials. The test is performed by rolling a heavy, cylindrical roller over a sample of the roofing material to simulate the effects of foot traffic and other loads on the roof surface.
The Benkelman Beam Deflection Test is a widely used pavement evaluation method and is particularly useful for flexible pavements, such as asphalt or lightly bound pavements. The test is relatively simple to perform and can provide valuable information on the structural condition of the pavement surface.
Determines the point where the pH of lime added to the soil produces no significant increase in pH of the soil. Used for assessing the liming rate for stabilised soils, pavement materials, pavement rehabilitation.
Determination of Unconfirmed Compressive Strength of Cement Modified or Stabilised Road Materials. For strength determination of Road Pavement Materials.
Similar to AS1289.5.1.1 as part of compaction control where MDD and OMC are determined except with addition of stabilisers or binders. Preludes other testing, usually Unconfined Compressive Strength.
The Maximum Dry Compressive Strength (MDCS) test is a standard test used to measure the strength of road materials, including rocks, aggregates, and asphalt. The MDCS test involves applying a compressive force to a cylindrical sample of the road material until it fails.
The Shrink Swell Index (SSI) is a measure of the potential for soil to undergo volumetric changes due to changes in moisture content.
A pointed cone (DCP) is repeatedly impacted with a 9kg mass from a specific distance and the number of blows in the in-situ soil counted for the rod to penetrate a specific distance. Perth Sand is similar to DCP but has a flat end. The measurement can correlate to pressure (kPa) and strength of the foundations, important for engineering purposes in design and construction of structures above soil layers.
The California Bearing Ratio (CBR) is a measure of the load-bearing capacity of a soil subgrade or base course. The test involves compacting a soil sample in a mold of known dimensions at various moisture contents and densities. A standard piston with a diameter of 50 mm is then pushed into the soil sample at a constant rate of penetration and the load required to achieve a penetration of 2.5 mm is measured. The ratio of the load required to penetrate the soil to that required to penetrate a standard material, usually crushed rock, is the CBR.
