Abstract
The invention provides polyolefin staple fibers especially useful for reinforcing pavement. The fibers have applied to their surface an amount of an antistatic finish sufficient to prevent the build-up of static electric charges when the staple fibers are fluidized or blown, and so diminish the resultant clumping of the blown fibers, while avoiding degradation of the nature of the fiber to adhere to paving compositions, and maintaining the adherence of the fibers to the pavement cement.
Claims30
A process for making a fiber-reinforced pavement comprising asphalt cement suitable for making or repairing a geoway, comprising:
- providing a mixing device adapted for mixing pavement comprising asphalt cement and polyolefin reinforcing staple fibers;
- providing reinforcing polyolefin staple fibers which comprise oleophilic olefinic staple fiber having on its surface an antistatic finish in an amount effective to prevent clumping when a multiplicity of the fibers are airveyed;
- airveying the staple fibers to the mixing device;
- providing a pavement comprising asphalt cement and conducting it to the mixing device;
- and mixing the airveyed staple fibers and the pavement comprising asphalt cement in the mixing device to make a fiber-reinforced pavement.
