Quality Management of Earthworks with Deflection-Based Devices – 14 May 2020 Seminar
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 rail applications. A transformation from density-based to modulus- based quality assurance (QA) approach involves technical and organizational challenges that must be recognized and addressed in order to develop an efficient and practical specification. This presentation covered the different concepts for quality management during construction that can result in both construction benefits and improved performance of the earthworks / pavement based on Dr Nazarian’s extensive experience, along with brief presentations of recent ARTC Inland Rail experiences with trialling Light Weight Deflectometer equipment.
The presenters were:
- Prof. Soheil Nazarian (Professor of Civil Engineering – The University of Texas at El Paso)
- Andy Doe (Geotechnical Project Manager – Inland Rail at ARTC)
You can download the presentation slides and listen to the webinar recording. The presenters were kind enough to answer your questions.
Dr. Nazarian is the McIntosh Murchison Endowed Chair Professor of Civil Engineering and the Director of the Center for Transportation Infrastructure Systems at The University of Texas at El Paso. With more than 35 years of experience in non-destructive testing of transportation infrastructure, he is currently the Chair of the Geotechnical Instrumentation and Modelling Committee of the Transportation Research Board and on the Executive Board of the International Society of Intelligent Construction.
Andy Doe is a Geotechnical Project Manager for Inland Rail at ARTC, responsible for new technology implementation. Andy has over 20 years’ experience in civil infrastructure works and is a Registered Professional Engineer of Queensland and a Chartered Geologist. Andy has carried out design, asset evaluation and geotechnical risk assessment for major infrastructure projects in Australia, Canada, the United Kingdom and Ireland.
Insitutek is our partner overseas for our test equipment. Ask them for a presentation or training for our products. I am sure you will be satisfied. They are a reliable and very kindly partner.
We purchased a PANDA 2 machine after using one from another laboratory. The information obtained has saved money on numerous jobs. It is reasonably priced and the after-market service has been great. Highly recommend using Insitutek.
I have known the team at Insitutek for over ten years. Their professionalism, positivity and enthusiasm for their work is outstanding and I am pleased to recommend them.

Compaction is one of the most important processes in pavement construction and, done well, leads to long-lasting pavement performance and reduced maintenance costs.
Our clients use Intelligent Compaction to create uniform efficient quantified compaction. Our Intelligent Compaction system provides:
We are delighted to officially announce our Ground Improvement portfolio.
For the last three years, we have been working on extending our offer from, just, in situ testing to testing and improving in situ conditions.
With our ground improvement portfolio, our focus is delivering more sustainable outcomes. Here is what we offer:
On 2 August 2024, geomechanics professionals gathered in Canberra for the Australian Geomechanics Society ACT Insitu Testing Practical Workshop. The event focused on practical demonstrations of key insitu testing methods, including Cone Penetration Testing (CPT), Static Plate Load Test (PLT), Dynamic Probing Super Heavy (DPSH), Light Weight […]
