Abstract

An ambient temperature applied asphalt emulsion material is disclosed for repairing traffic-bearing surfaces. A method of applying the asphalt emulsion material for quick hardening by the addition of a hardening agent is shown. An applicator wand which applies the emulsion and hardening agent mixture to a surface and smooths the applied material for hardening level with the surface.

Claims

1. A method of filling cracks in a traffic-bearing surface comprising the steps of:

a) applying an anionic emulsion including water, asphalt, latex, and ground rubber into a crack to be filled;

b) adding a hardening agent with the anionic emulsion as it is being applied, wherein the step of adding a hardening agent comprises the step of mixing salt water with the anionic emulsion as it is being applied.

2. The method of filling cracks as in claim 1 wherein the step of applying an anionic emulsion into a crack to be filled comprises the step of directing a spray of the emulsion into the crack with an applicator wand and the step of mixing salt water with the anionic emulsion comprises the step of spraying a mist or a fog of salt water directly into the spray of the emulsion as it is being directed into the crack to be filled.

3. A method of filling cracks in a traffic-bearing surface comprising the steps of:

a) applying an anionic emulsion including water, asphalt, latex, and ground rubber into a crack to be filled.; and

b) adding a hardening agent with the anionic emulsion as it is being applied, wherein the step of adding a hardening agent comprises the step of mixing salt water into the emulsion prior to applying the mixture to the traffic-bearing surface.
