A large number of nondestructive testing devices and associated expertise are available at CTIS. These include:
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.
UTEP has the expertise and/or equipment to conduct comprehensive functional and structural evaluation of pavement in the field. The areas of expertise include:
A large number of nondestructive testing devices are available at CTIS. These include:
Ground Couple GPR Device: To detect moisture in pavements, layer interfaces and rebar in concrete pavements at slow speeds.
Air Launch GPR Device: To detect moisture in pavements, layer interfaces and rebar in concrete pavement at high speeds.
SPA - Seismic Pavement Anaylyzer: Non-destructive seismic testing for estimating pavement layer moduli and pavement impulse response.
PSPA - Portable Seismic Property Analyzer: To measure the average modulus of the layer based on generating and detecting stress waves in a layer.
Infrared Imaging Camera: To detect voids and delamination in structures.
LWD - Light Weight Deflectometer: To estimate modulus for unbound pavement materials.
Geogauge: To estimate modulus for unbound pavement materials. Soil Density Gauge (SDG): To determine the in-place density and moisture content of unbound pavement materials.
DCP: To measure the penetration rate that can be converted to the CBR, resilient modulus, unconfined compressive strength, and shear strengths using empirical relationships.
Moisture+Density Indicator (M+DI): To measure moisture content and density using Time Domain Reflectometry.
