Melbourne’s road network spans over 23,000 km, from the inner city tram corridors to outer suburban arterial roads, and much of that pavement was laid decades ago on variable basalt and siltstone subgrades. An existing pavement evaluation tells you exactly what’s left in the structure before you spend a dollar on rehabilitation. We use falling weight deflectometer testing, core recovery, and dynamic cone penetrometer profiling to measure layer stiffness and thickness across your site. When the subgrade itself is questionable, we recommend a complementary infiltration test to assess drainage behavior beneath the pavement.
A targeted existing pavement evaluation can reduce rehabilitation costs by 25 to 35 percent by avoiding over-design and identifying salvageable layers.
