The Fourier Transform Infrared Device (FTIR) has the ability to fingerprint key indicators of materials, such as asphalt binder, to ascertain their composition for use in quality control. The FTIR is one of the devices employed in FHWA’s Mobile Asphalt Technology Center (MATC) lab. This video shows some tips and tricks that our crew have learned about the test along the way.

The Federal Highway Administration has partnered with the Geosynthetic Materials Association to develop a mobile application that provides information on the various types and functions of geosynthetic materials in road construction and maintenance programs. The video provides a brief tour of the mobile application’s many features for use when conducting onsite inspections. The app is available at no charge in the Google Play and Apple Stores.
