Abstract
An apparatus and method for dislodging a solidified plug formed in the delivery line of hot asphalt blocking the delivery of the flowable asphalt to a site close to or remote from the site of application to a surface to be fixed or coated with the flowable hot asphalt.
Claims11
An apparatus to dislodge a plug of asphalt solidified in the exit port of an asphalt-containing distributor truck comprising:
- a tank containing an inert, non-flammable gas under pressure;
- an exit port extending from said tank terminating in a coupling means, releasably attached to said exit port of said asphalt-containing distributor truck;
- valve to open said pressure device of said inert, non-flammable gas from said tank;
- regulator gauges associated with said pressure device, wherein said pressures are controlled in order to dislodge said solidified plug contained in said asphalt-containing distributor truck in order to restart the flow of asphalt from said distributor truck.
An apparatus to dislodge a plug of asphalt solidified in the exit port of an asphalt-containing distribution tank having a pressure device comprising:
- a tank containing an inert, non-flammable gas under pressure;
- an exit port extending from said tank and terminating in a coupling means, releasably attached to said exit port of said asphalt-containing truck;
- and
- a regulator gauge on said pressure device to controllably release said inert, non-flammable gas to dislodge said plug of the exit port of the asphalt-containing distributor tank.
A method to dislodge a plug of asphalt solidified in the exit port of an asphalt-containing distributor tank comprising the steps of:
- a) providing a pressure device comprising:
- a tank containing an inert, non-flammable gas under pressure;
- a supply valve on said tank;
- an exit port extending from said tank and terminating in a coupling means for releasable attachment to an exit port of an asphalt-containing truck;
- a regulator gauge on the tank of the pressure device to release said inert, non-flammable gas;
- a vent valve on the pressure device;
- and
- b) attaching said pressure device to the exit port of said asphalt-containing truck using the coupling means;
- c) setting the regulator gauge to zero pressure;
- d) closing the vent valve on the pressure device;
- e) opening said supply valve;
- f) starting the flow of said inert, non-flammable gas;
- g) increasing the flow of said inert, non-flammable gas up to a pressure of 90 psi or until said plug of asphalt is dislodged;
- h) closing supply valve;
- i) opening said vent valve to release pressure;
- and
- j) removing said pressure device from said exit point of said asphalt-containing truck.
