Fiber Pave, Polypropylene Fiber

摘要

The report documents the performance of Fiber Pave. Fiber Pave 3010, which ismanufactured by Hercules Incorporated, consists of short-length polypropylene fibers designed for use as a reinforcement in bituminous concrete and asphalt pavements. It is marketed for its ability to increase the cohesive strength of the asphalt binder, improve its workability, and extend the service life of the pavement by making it more resistant to shoving, rutting, and thermally induced reflective cracking. It is very difficult to draw any definitive conclusions in terms of overall pavement performance of the Fiber Pave. The test section which contain the fibers and the control section performed equally well. Both the cracking and rutting at the end of the evaluation for both the test and control sections were minimal. However, with the thickness of the widened section (4-1/2 inches) it is possible that the three year evaluation was not long enough to fully evaluate the pavement's ability to resist rutting.
