In-situ non-destructive testing (NDT) devices that estimate the stiffness parameters of a constructed pavement structure are emerging. Such stiffness parameters are more representative of the performance predicted by the mechanistic design process for both road and...
There is nothing like jumping in at the deep end! With buy in from Fortescue Metals Group, BHP and Rio Tinto, we brought together our supply partner, Sol Solution from France, and the extreme conditions of deep fouled ballast and the Pilbara climate to test to see...
Have you noticed an increase in the number of questions relating to modulus based testing for soils? We certainly have. We are now wondering how soon this trend will gather pace in Australia and New Zealand for asphalt. It’s already well underway in Europe and...
Since the earliest trials of Intelligent Compaction (IC) in Australia nearly 10 years ago, we have recognised that a well-developed local knowledge base will be critical for the successful implementation of IC. IC is a major aid to attain high compaction quality and...
We find our clients are increasingly demanding more accurate and more representative results that provide better insight on what’s going on below the surface when they are designing or constructing projects so they can make well-informed decisions in a timely manner....
The acceptance of earthwork and unbound pavement construction in Australia currently relies on density testing and CBRs for Quality Assurance (QA). Though its National Asset Centre of Excellence (NACoE) research program, Queensland Main Roads has sponsored an ARRB...
