Understand your soil’s moisture–density relationship and laboratory bearing properties. Bring your specification to Statewide Geotechnical’s Boronia Laboratory so we can confirm the testing your project requires.
Establishes the relationship between moisture content and dry density under a specified compactive effort. This identifies maximum dry density (MDD) and optimum moisture content (OMC) for the tested material and method.
Useful when your specification calls for a laboratory reference for earthwork compaction control.
Standard and modified compaction02
California Bearing Ratio
CBR measures resistance to penetration under defined laboratory conditions. It is used in pavement assessment and design to help characterise the bearing properties of subgrade and pavement materials.
The specified preparation and test conditions matter when interpreting or comparing results.
Project and materialYour project reference, material description, sample count and source or location.
Specification or test scheduleInclude the requested tests and any specified compaction effort or CBR test conditions. If these are unclear, send the relevant specification.
Reporting requirementsYour required date, contact details and any requirement for accredited testing.
BEFORE DELIVERY
Confirm your samples before you send them.
Contact the laboratory before sampling or dispatch. Quantities and preparation depend on the requested tests and material, so there is no single sample size listed here.
Use the method required by your project specification. Share that specification with the laboratory so the appropriate test can be confirmed; the methods should not be treated as interchangeable.
Can you confirm CBR test conditions?
Send any specified preparation, density, moisture and soaking requirements with your enquiry. The laboratory will review the requested conditions before testing begins.
How long will testing take?
Timing depends on the test programme, preparation, sample condition and workload. Let us know your required reporting date when requesting a quote.
Will my tests be NATA-accredited?
Accreditation applies to specific activities, not every possible test or condition. Tell us if accredited testing is required so we can confirm the applicable scope before work begins. View the laboratory’s NATA listing ↗.
