Matrix was a key partner in a consortium of 3 companies, engaged by 5R Constructors to perform all earthwork related Quality Assurance testing. Matrix provided experienced senior level Registered Geotechnical Engineers, Certified Technicians and Project Engineers. The project involved the use of soil/rock mixtures in constructing the Runway embankment sections, with some measuring up to 90 ft in height. Testing of this mixture included the development of empirical field- based unique procedures that entailed large scale “balloon density” testing, as well as proofrolling and consolidation/settlement measurement and analysis. These procedures were used to supplement ASTM/AASHTO standards and procedures.
