Evaluation of Fiber-Reinforced Asphalt Pavements – Phase 1: Laboratory Study
ITD is planning to use three different reinforcing fibers for a 3.22 mile long pavement project on US-30 east of Montpelier City in Southeast Idaho (ITD Key No. 13104). The project will involve building four sections; three with fibers and one control section. There will be four different HMA mixes (three with fibers and one as a control). ITD plans to use this project as a pilot study to evaluate the effectiveness of using fibers in HMA to improve the pavement resistance to cracking and rutting. There are three vendors who will supply the three types of fibers. Forta Co., Nycon Corporation and Surface-Tech, Inc. There is a need to evaluate the proposed mixes in the lab. Lab evaluation is to assess and compare the performance of these mixes in the lab, and to establish mix properties data that shall be needed for performance evaluation using AASHTOWare ME Pavement Design software.
