Subsurface Scanning and Mapping
INFRASENSE is a client focused consulting firm that specializes in the nondestructive evaluation NDE of bridge decks highway and airfield pavements tunnels parking structures and other transportation facilities The company was founded in 1987 with support from National Science Foundation NSF Small Business Innovative Research SBIR Grants We provide our clients with highly accurate and actionable information enabling cost effective network level assessments and project specific maintenance and rehabilitations decisions
BRIDGE DECK SCANNING SERVICES CONCRETE STRUCTURE SCANNING Infrasense has provided nondestruuctive Infrasense has completed projects for clients in all fifty US States Canada Europe Asia and the Middle East Our staff brings over 100 years of practical experience and our methods are supported and continually improved through ongoing research and development efforts evaluation consulting and testing services using ground penetrating radar GPR PAVEMENT STRUCTURE EVALUATION infrared thermography IR falling weight deflectometer FWD acoustic scanning electromagnetic induction EMI UTILITY LOCATING MAPPING seismic ultrasonic imaging SUBSURFACE INVESTIGATIONS abroad LEGEND number of projects 100 50 99 AERIAL IMAGING 25 49 5 24 1 4 zero
Infrasense uses ground penetrating radar GPR infrared thermography IR and highresolution video HRV to scan bridge decks at normal driving speeds The GPR and IR data is collected according to ASTM 6087 and ASTM 4788 using state of theart technology Following data collection an analysis is carried out using our proprietary software systems which utilize methodologies developed through research and supported with over 30 years of experience The final result is a comprehensive NDE inspection report with concrete conditions quantified and mapped BRIDGE SCANNING TECHNOLOGIES RESULTS Infrared thermography IR delamination and deterioration high resolution visual HRV patching and spalling ground penetrating radar GPR approach slab voids deterioration ultrasonic methods layer thicknesses rebar spacing TO DETECT AND REPORT
We deploy our high speed vehicle based GPR system according to ASTM 4748 and synchronized with both linear distance and GPS coordinates for location referencing Data collection can be performed at normal driving speeds without lane closures or traffic disruptions The final results can be provided in formats including cross section plots of the pavement structure showing depth of all layers tabular results showing layer thicknesses at FWD test locations synced with GPS quantities and maps of areas with subsurface voiding moisture ingress or stripping GIS compatible geospatial plots and geodatabase layers i e ArcGIS LAYER THICKNESS SURFACE PATCHING SPALLING ASPHALT DEBONDING STRIPPING DETERIORATION JOINTS PCC PAVEMENT SCANNING
TRADITIONAL CHAIN DRAG INSPECTION AERIAL IMAGING AERIAL INSPECTION Data Validation 2017 Pilot Study with WisDOT found 86 correlation with vehiclebased IR surveys performed according to ASTM D 4788 03 Results With Aerial IR you have a record of the underlying data utilized to create the delamination maps so what you see is what you get Advantages of Aerial IR BRIDGES SCANNED PER DAY EFFICIENCY Hundreds of decks scanned per day 200 SAFETY No exposure of personnel to traffic ACCURACY IR results within 4 of chain drag on average AFFORDABILITY A fraction of the cost of traditional inspections 25 5 TRADITIONAL SURVEYS VEHICLE BASED SURVEYS AERIAL SCANNING
LAYER MODULI EFFECTIVE SN REMAINING LIFE REQUIRED OVERLAY PAVEMENT DEFLECTION TESTING Infrasense now provides falling weight deflectometer FWD testing to evaluate physical pavement properties Testing is performed in accordance with ASTM 4694 and ASTM 4695 The FWD deflection data can be combined with GPR layer thickness results to provide pavement structure deliverables in tabular graphical and GIS formats that can be easily integrated with pavement management systems PMS Infrasense also has experience integrating Traffic Speed Deflectometer TSD data with GPR layer thickness information to provide continuous pavement structure results LOAD TRANSFER EFFICIENCY
Infrasense utilizes a suite of nondestructive testing NDT methods including ground penetrating radar electromagnetic induction EMI and EM 61 to locate subsurface utilities and provide Quality Level QL B surveys We reference the NDT data using both a survey grid and high precision differentiallycorrected GPS coordinates for the best possible accuracy of deliverables Utility line locations and depths can be provided as CAD compatible site maps SUBSURFACE UTILITY ENGINEERING CADD COMPATIBLILITY SUE QUALITY LEVEL B FIELD MARKINGS UTILITY MAPS LOCATIONS AS BUILTS ACOUSTICS METHODS GROUND PENETRATING RADAR GPR GPS TAGGED DATA ELECTROMAGNETIC INDUCTION EMI DEPTH SERVICE TYPES
TUNNELS STORAGE FACILITIES RETAINING WALLS BUILDING SLABS PARKING STRUCTURES Infrasense uses ground penetrating radar GPR supplemented with other NDE techniques to scan a variety of concrete structures Typical conditions include rebar level corrosion delaminations rebar spacing and depth slab wall thickness conduit locations estimated compressive strength potential voids and moisture ingress The final result is a comprehensive NDE inspection report with concrete conditions quantified mapped and delivered in a format that best meets the client s needs CONCRETE STRUCTURE SCANNING
