LRRT rock mechanics laboratory was established in 2011 based on Dr. Tonon’s rock mechanics research as a faculty member first in Geological Engineering at the University of Utah, and then in Civil Engineering (rock mechanics and underground excavations) at the University of Texas at Austin. Our lab specializes in rock testing with special emphasis on tunnels and underground excavations, and tests to characterize the abrasion of soils (Soil Abrasion Test (SAT), the Miller Abrasion Number, the Slurry Abrasion Response (SAR) , the LCPC Broyability and Abrasiveness) for Earth Pressure Balance Machines (EPBs), Slurry Shields, and deep foundations.
The rock mechanics lab is truly unique in the World: important examples include the Norwegian (NTNU-Sintef) tests to determine the Drilling Rate Index and the Cutter Life Index for the prediction of rock TBM performance and wear, as well as drill bit performance and consumption; the Schimazek Index for the prediction of rock TBM performance; Cerchar tests for rock abrasion and prediction of excavation tool wear for TBMs, hydromills, drill bits, and drilled-shaft chisels; and uniaxial, triaxial, and direct shear tests by means of servo-controlled apparatuses in order to:
Our 3 MN (675 kip) high-stiffness testing frame for uniaxial and triaxial tests on hard rock is specially designed and built to support the shock from the explosive failure of extremely hard rock specimens; indeed, rock specimens with uniaxial compressive strengths of 500 MPa (72 ksi) have been tested until now. .
From 2009 to 2015, Dr. Tonon served as Chair of ASCE Rock Mechanics Committee , and he is a member of the ISRM Commission on Rock Fractures. Peer-reviewed journal publications specifically related to rock testing and stemming from Dr. Tonon’s lab experience include:
Our Quality System stems from our attitude to listen to our Clients' needs and our intimate knowledge of rock mechanics; our Quality System is currently ISO 9001-2015 certified by DNV-GL. A copy of our certificate may be found HERE.
