The Nebraska Department of Transportation is hosting the FHWA Mobile Concrete Technology Center with an open house at the Nebraska Transportation Center on July 20. The open house will feature testing of samples from an NDOT project collected earlier in July.
The FHWA’s Mobile Concrete Technology Center (MCTC) introduces agency and industry personnel to the state-of-the-art concrete technology in materials selection, mixture design, field and laboratory testing, and pavement evaluation. The MCTC is visiting Nebraska to introduce new test
methods related to the Performance Engineered Mixture (PEM) initiative and other concrete technologies.
This is a unique opportunity to learn about the new PEM tests that deal with design and construction of concrete mixtures for performance. Additionally, the FHWA MCTC showcases other concrete technologies. Many of these technologies are state of the art, provide information in real time.
Demonstration and interactive opportunities for the new PEM
test methods such as:
- Super Air Meter (SAM) - Cutting edge technology to measure air void characteristics of concrete
- Surface Resistivity - Rapid measurement to indicate permeability of concrete
- Box Test - Measurement of workability
- V-Kelly - Measurement of workability
- Phoenix - Measurement of water content
- Capillary Pressure Sensor System - First technology that directly measures capillary pressures in fresh concrete
- Mira - Ultrasonic Pulse Echo (MIRA) equipment.
