Abstract: In the method for applying horizontal markings to road surfaces, a water-thinnable emulsion paint which is acid-coagulable is used and is brought into contact with an acid. This acid is scattered or sprayed onto or into the sprayed paint, the acid being in the form of an aqueous solution, a powder or particles wetted with acid. The method brings about drying within one or a few minutes. Using road-marking vehicles, horizontal markings can thus be put down with virtually no closing-off of the mobile operations site.

Abstract: Roadway traffic control marking tape and reflective sheeting are known in the art for providing temporary delineation and demarcation of traffic lanes in order to guide the flow of traffic through detours, construction areas and the like. Traffic channelizers and barricades are also well known in the art as barriers to discourage crossing the lanes onto the other side thereof. When work on highway lanes is completed, and traffic is redirected to newly opened lanes, the tape is generally removed. When it breaks during removal the job is particularly demanding. Damage to traffic channelizing devices which are hit by fast moving vehicles leads to their frequent replacement. Hence it has become desirable to recycle them. The recycling process requires that the reflective sheet first be removed. But the recycling process too has been hampered by the difficulty of sheet breaking during its removal.

Abstract: A waterborne paint for traffic marking contains as an emulsion binder, a support polymer formed of styrene and acrylic acid monomers and having an acid value of between about 50 and about 250 and a hydrophobic emulsion polymer comprised of acrylic ester monomers and optionally including styrene monomers.

Paints in accordance with the invention contain between about 10 and about 15 wt. percent of the emulsion polymer, between about 60 and about 75 wt. percent fillers or pigments and between about 9 and about 18 wt. percent water. Due to the high solids loading and low water content, the waterborne traffic marking paint is fast drying. Colored paints prefereably utilize banded pigments.
