Abstract
A method for producing a thermoplastic filler for eliminating surface damage to concrete or asphalt surface is described, wherein the method comprises the steps of mixing stone chips, sand, a powdered material and a bituminous binding agent to a homogenous mixture which is in constant motion at a temperature of between about 180° C.-240° C., with a coolant being added subsequently to the mixture in a rapid manner thereby converting the mixture into a non-cohesive granulate of small pellets due to the high surface tension of the various constituents, and wherein the granulate can be heated to convert it to a free-flowing or spreadable filler having strong adhesive properties.

A method for producing a thermoplasctic filler for use in eliminating surface damage in concrete and asphalt surfaces and as a joint compound comprising the steps of:
- mixing stone chips, sand, a powdered material and a bituminous binding agent into a homogenous mixture, heating the mixture to a temperature of about 180° C. to 240° C. and thereafter subjecting the mixture to a cooling shock by cooling the mixture, which is under constant agitation, in a rapid manner adding a coolant to the mixture.
