Evaluation of the Tyrsolv Crumb Rubber Asphalt Modifier
This report covers the mix design, plant modifications, construction and performance of the Tyrsolv asphalt modifier. Tyrsolv is a treated ground rubber made from waste tires. Three projects using ground waste tires as an asphalt modifier (Tyrsolv) were placed. The first project, constructed in 1995 and located in District 6-0, Chester County, SR 0041, failed from the beginning due to a non-uniform handling of the product. The second project was constructed in 1998 in District 9-0, Fulton County, on Interstate 70. A third project was constructed in 1998 on Interstate 81 NB in Schuylkill County. PTI determined that Tyrsolv has the potential to enhance the base asphalt properties two PG grade on high temperature side of the grading without adversely affecting the low temperature grading. Although Tyrsolv Asphalt costs more, and did not out perform control mixes, it did perform satisfactory. PENNDOT may consider the use of Tyrsolv providing an approach can be developed to make it cost competitive with conventional sources of asphalt.
