Nondestructive Field Testing
A large number of nondestructive testing devices and associated expertise are available at CTIS. These include:
- Seismic Pavement Analyzer
- Potable Seismic Pavement Analyzer
- Lightweight Deflectometer
- Geogauge.
- GSSI air-launched and ground-coupled GPR units with antennae ranging from 400 MHz to 2.1 GHz.
CTIS in a partnership with the Department of Geological Sciences operates the Laboratory for Environmental and Engineering Geophysics (LEEG) at UTEP. LEEG is an $800,000 facility funded by the Department of Defense and operates virtually any geophysical methods applied in the field of engineering, from electromagnetic methods, to several electrical methods, to most seismic methods.
UTEP also owns and operates a LIDAR system for remote inspection of infrastructure.
Over the years, CTIS has accumulated a large number of digital recording devices, signal analyzers and a vast variety of sensors. If need be, any test method can be configured and performed manually in a short period of time.
Field Testing
UTEP has the expertise and/or equipment to conduct comprehensive functional and structural evaluation of pavement in the field. The areas of expertise include:
- Advanced and Routine Structural Evaluation of Pavements with FWD
- Pavement Characterization with Seismic Devices (such as SPA and PSPA)
- Network Level And Project Level Survey With Ground Penetrating Radar
- Ride quality of pavements with profilers
