Mobile Laboratory for Rapid Evaluation of Transportation Infrastructure

The Mobile Laboratory for Rapid Evaluation of Transportation Infrastructure, supports research related to in-service condition and behavior of infrastructure systems. The laboratory is equipped with a variety of testing equipment suited for rapid load testing and monitoring as well as equipment dedicated to non-destructive evaluation of civil infrastructure.

Available Equipment:

  • Smart Travel Van – A vehicle designed to collect on-site, real-time data traffic data has been integrated in the Mobile Laboratory for Rapid Evaluation of Transportation Infrastructure for field-testing purposes. The van allows for the collection of field data at any location accessible by a vehicle including heavily traveled freeways, busy signalized intersections, work zones, or remote rural locations. In addition, the Smart Travel Van is a non-intrusive data collection device and does not require placing or installing any equipment in travel lanes. The van’s data collection capabilities complements the Mobile Laboratory for Rapid Evaluation of Transportation Infrastructure and provides a platform for integration of new sensor technologies for condition assessment.
  • Bridge Diagnostics – Wireless Bridge Evaluation System: Portable high-speed data acquisition system with wireless base station and wireless 4-channel nodes (6). Capable of measuring a suite of available sensors including strain, displacement, rotation, acceleration, and other voltage transducers. System is ideally suited for rapid load testing and monitoring applications.
  • Campbell Scientific Data Acquisition Systems: 1) CR9000X – High-speed and rugged acquisition system for high-speed measurement and long term monitoring. Modular input cards capable of measuring a suite of available sensors including strain, displacement, rotation, acceleration, and other voltage transducers. System is ideally suited for rapid load testing and monitoring applications. 2) CR 3000 – self-contained, rugged datalogger that includes battery-backed, real-time clock and nonvolatile data storage. The CR 3000 along with two available CDM 305 units is capable of measuring vibrating wire gages at frequencies up to 100Hz. It is designed for stand-alone operation in harsh, remote environments. 3) CR 1000 – Rugged general use datalogger with a broad range of measurement and control functions.
  • Correlated Solutions digital image correlation systems (3D and 2D) – Non-contact, optical, full-field deformation measurement system. The system is able to measure arbitrary displacements and strains from 50 microstrain to 2000% strain and above, for specimen sizes ranging from <1mm to >10m. This system includes 6 CCD cameras with suite of lenses (8mm, 12mm, 35mm, and 75-300mm) and is equipped to integrate the FLIR A615 IR camera. System was designed specifically for civil engineering application and has capabilities for both laboratory and field use.
  • GSSI StructureScan Mini HR (2600 MHz) Ground Penetrating Radar: This is an all-in-one handheld high-resolution GPR system for concrete inspection. The system is suited for locating rebar, conduits and post-tension cables in depths of up to 16 inches (40 cm) and can be used to provide a measure of subsurface deterioration in concrete structures.
