Method for Producing Bituminous Coatings With Reduced Tackiness

摘要

The method according to the present invention renders the surface of bitumen materials to be non-tacky, and minimize or eliminate the loss of the bitumen materials to traffic. The method according to the present invention may also be used on top of prime coat and fog seal, to reduce tackiness of bitumen materials from cured bitumen emulsions, and to decrease unnecessary and unwanted tracking by passing traffic.

1. A method for reducing the tackiness of a bitumen coating on a base substrate,
the method comprising the steps of
applying a bitumen based material on the base substrate, andsubsequently applying a tack reducing material on the surface of the bitumen based material, wherein the tack reducing material comprises a dispersion, emulsion or solution of a component selected from the group consisting of an inorganic mineral, a waxy or resinous material, an organic polymer or pre-polymer, a chemical hardening agent, and a combination thereof; wherein the tack-reducing material contains less than 15 wt % of bitumen based material; and wherein the tack-reducing material is substantially non-reflective as defined by having a L* of 25 or less.
