Abstract
An asphalt heater system includes a source of a flow of inert gas, a heater for heating the flow of inert gas and means for directing the flow of heated inert gas to the asphalt surface, wherein the means for directing the flow of heated inert gas to the asphalt surface is a lance. Such systems are suitable for use in methods for repairing defects in an asphalt surface.
Claims19
An asphalt heater system, comprising a source of a flow of inert gas, a heater for heating the flow of inert gas and means for directing the flow of heated inert gas to the asphalt surface, wherein the means for directing the flow of heated inert gas to the asphalt surface is a lance;
- wherein, the heater is configured to heat the inert gas flow to a temperature of from about 40° C. to about 650° C. and to direct the heated inert gas at a flow rate of between 100 and 600 L/min when the heated inert gas exits the lance.
A method for repairing a defect in an asphalt surface, wherein the method comprises the steps of:
- providing a flow of inert gas;
- heating the flow of inert gas;
- heating the asphalt surface using the flow of heated inert gas;
- and
- providing a filler material to the defect in the road surface, wherein the asphalt surface is heated using a lance;
- wherein the inert gas is heated to a temperature of from about 40° C. to about 650° C.;
- and
- wherein the method further comprises a step of mechanically agitating the filler material so as to mix together the asphalt surface and the filler material.
