Engineering and Research Int’l, Inc. (ERI) is a civil engineering firm specializing in pavement management, pavement design, pavement testing, materials testing and Geographic Information Systems (GIS), as well as research and education in these areas. Since its inception in 1982, ERI has been committed to maintaining superiority in the field of pavement engineering.
ERI’s staff is well trained in using state-of-the-art mechanistic analysis and design techniques for pavements. Currently, ERI owns and operates an Automated Distress Vehicle System that gathers digital images directly ahead of the vehicle, in the Right of Way, and downward images on the pavement, along with GPS coordinates, as it travels at highway speeds. ERI operates both KUAB and Dynatest Falling Weight Deflectometers (FWD). ERI also owns Ground Penetrating Radar, Laser Road Profiler and Pavement Skid Friction Test Systems. The employees of ERI have been involved in the development and implementation of MicroPAVER Pavement Management System (PMS), and the Pavement Condition Index (PCI) method for visual rating of highway and airport pavements.
