CTI personnel and affiliated faculty members have continued to serve on national, regional, and state committees that have increased CTI’s prominence at all levels. It’s emerged as a national leader in crash data analysis as CTI houses Connecticut’s vehicle crash data records management. The Connecticut Crash Data Repository project at CTI is providing researchers, town engineers, planners, and the public with unprecedented access to crash data for transportation safety analysis. The success of this project resulted in Conn DOT expanding the funding of the Connecticut Transportation Safety Research Center at CTI. More information about CTI can be found at http://www.cti.uconn.edu/.

Fully automated triaxial and direct shear devices are available. The triaxial apparatus also accommodates flexible wall permeability, consolidation, and stress path testing. The direct shear device also allows reversal testing. A variety of sensors (load cells, displacement transducers, pore pressure transducers, bender elements, etc.) are also available.

CKC automated cyclic triaxial device, which is upgraded with some new hardware and updated to a National Instruments-based data acquisition system. One of the triaxial cells is fitted with bender elements.
A 51 cm diameter, flexible wall calibration chamber is available. Variable sample heights are possible. The chamber has allowances to apply vacuum and accommodate saturated samples including back pressure saturation capabilities and pore pressure measurements. A set of two bender elements and an internal miniature pore pressure transducer have been incorporated into the calibration chamber. Another 15-cm diameter, flexible wall calibration chamber is also available.
A 1.1 cm diameter piezocone made by Fugro – Associated driving mechanism was designed in-house, which allows a total travel distance of 75 cm and varying penetration rates, including 2 cm/s. This piezocone could be used with both calibration chambers mentioned above.
A set of flat plate piezoceramics transducers along with a function generator, oscilloscope, and NER AutoLab data acquisition software are available. This system was developed in collaboration with New England Research, Inc. (NER), a small R&D firm in Vermont. The system can also be used for bender elements.

Equipment to perform grain size, Atterberg limits, moisture and density, standard and modified Proctor, constant and falling head permeability tests, a sieve shaker, and automatic standard and modified Proctor compactor are available.
Bruker Skyscan 1173 micro-CT. The equipment uses a 5 Mp (2,240 x 2,240 pixels) X-ray camera and 130 kV source. Specimens as big as 140 mm wide and 140 mm high can be scanned. A maximum resolution of 6 microns can be achieved depending on the specimen size. The advanced visualization software allows particular density ranges in a sample to be highlighted or hidden, spinning, and slicing to view internal structures; movies can be made of all these operations to enhance the dissemination of the results. Both the imaging and analysis are non-destructive, making this technique more attractive than some other conventional (and destructive) tests.
Split box, vertical cut, and simple direct shear devices for shear strength testing.
AutoLab 1500 – Manufactured by NER Inc. is a fully functional triaxial apparatus designed to perform coupled processes experiments on rock specimens for petrophysical, mechanical, and flow characterization at high confining pressure, pore pressure, and temperature. Some of the key features of the instrument are deformation experiments for conventional and specialized loading paths; servo-hydraulic control of strain rate, force, confining pressure, pore pressure, and flow rate; pore pressure intensifier compatible with water, brine, oil, and gas (including CO2); control of pressures and temperature at reservoir conditions; and integrated electronics console for servo amplifiers and signal conditioning.
A surface grinder manufactured by Clausing Industrial Inc., (Model: CSG618H) is a high-precision grinding machine used to grind the end surfaces of rock specimens for geomechanical and flow testing. The instrument’s high precision cartridge type spindle supported by preloaded precision angular contact ball bearings and roller bearing and driven by a V3 class motor allows highly accurate grinding performance.
