It’s always rewarding when we can bring both our “test” and “improve” capabilities to the same project.
This was the case with a recent case study for the application of TERRA-3000®, our clay soil stabilisation product in the City of Ballarat, VIC, which we tested using the Light Weight Deflectometer.
Council drivers for using TERRA-3000® on this 1.6km section of Gillies Road included:
1. 4x previous projects in the City of Ballarat municipality using TERRA-3000® on problematic roads over the last 7 years with all treated sections still performing well
2. Several previous attempts to rejuvenate this continually failing section of pavement using conventional approaches
3. Lower cost by:
- treating clay soil in situ (rather than remove and replace)
- use of approx. 30% clay content “red dredge” marginal material to raise the road level, instead of using higher grade more costly quarried base material
- significant reduction in the pavement depth required
- less truck movements bringing in quarried material
4. Reduced environmental impact
There are two primary issues that cause pavement degradation – moisture ingress and heavy traffic loading. TERRA-3000® addresses both of these for cohesive pavement materials. Find out more.

Subsequently, a chip seal wearing course was applied and the road was line marked.
If you have problematic roads that previous attempts to rejuvenate using conventional approaches have failed to rectify, we’d be keen to explore with you.
