During the time of construction, samples of the fiber reinforced HMA, along with samples of a conventional (control) HMA mix, were collected for laboratory testing. 2) Conduct preliminary laboratory experimental testing of four different fiber reinforced HMA mixes, along with complementary conventional (control) HMA mixes, in order to develop a preliminary characterization of various mechanical and performance properties of each mix. For this project, HMA mixes from Rapid City, South Dakota, Sioux Falls, South Dakota, Taylors Falls, Minnesota, and Box Elder, South Dakota were tested in the laboratory. 3) Determine if further investigation of fiber reinforced HMA was warranted. The goal of the preliminary laboratory experimental program was to demonstrate the feasibility and potential improvement in pavement performance with using fiber reinforced HMA based on the material properties, which may lead to the need for further detailed analysis of the technology within South Dakota.143
