This page contains information about research projects that are currently underway.

  • Project Description:
  • This project will be a pilot study to evaluate three types of fiber in HMA. The fiber and HMA will be used on roads near Montpelier. The proposed mixes will be evaluated in the lab. Assessment and evaluation will establish mix properties data that will be needed for performance evaluation using AASHTOWare ME Pavement Design software.
  • The objectives of this project are:
  1. Determine the effectiveness of using fibers in HMA to improve cracking and resist rutting.
  2. Enhance safety and reduce maintenance cost through the improvement to cracking and rutting.
  3. Quantify cost savings and added value for better performance of the HMA.
