Abstract

A substantially permanent pavement marking system using a polymer modified cement material to provide a raised marking that extends above the surface of the pavement. The lines are formed by taping off the desired outline shape of the marking. The pavement marking material is of such a consistency that it will set up to form a thick layer and not flow over the tape and will harden forming a raised marking.

Claims

1. A method of marking pavement for traffic control comprising:

a) cleaning a pavement area to be marked;

b) forming a border around the pavement area to be marked by applying tape to outline the pavement area to be marked to form a marking space;

c) substantially covering said marking space with a layer of liquid acrylic material and allowing said acrylic material to dry;

d) pouring polymer modified cement onto said acrylic layer, said polymer modified cement material being of a consistency that it will build up and not flow across said border;

e) forming said polymer modified cement by moving a line screed having a pair of side members and an arched surface spanning said side members along the marking space with said side members sliding along said border and said arched surface spanning the marking space and forming said polymer modified cement into an arched shape; and

,

f) allowing said polymer modified cement to dry.

2. The method of claim 1, further comprising the step of:

a) applying a layer of fiberglass cloth over said acrylic resin and further saturating said fiberglass cloth with said acrylic resin; and

b) allowing said acrylic resin and fiberglass cloth layers to dry.

3. The method of claim 1, further comprising the step of:

a) applying a sealant over said polymer modified cement.

4. The method of claim 1, wherein the step of forming said polymer modified cement includes:

a) shaping said cement into an arched shape having a height of no more than one eighth of an inch.
