Abstract

Pavement markings have an important contribution to the safety of people and vehicles on the roads. Many types of pavement marking materials have been used; and recently, the polyurea material has been used as binder in pavement marking paint. This type of paint has high retroreflection and high durability, so it has been widely applied at the airports and highways in America, Europe... This article introduces some initial results of study and production of polyurea pavement marking paint with the formula: binder/hardener ratio(1.3/1 pkl), 42% of pigment and filler, 10% of reflective balls, rheological additive, and dispersive additive to create outstanding features (retroreflection > 260 mcd/m²/lux).
