Abstract

The present invention provides for a method for automatically delivering and applying hot asphalt in a liquid state for easy spreading to a roof surface and an apparatus for performing this process. The method involves heating the asphalt to a liquid state and maintaining the temperature while pumping the hot asphalt from ground level to roof level to a hand held spray jet applicator which also rolls the asphalt smooth. The method employs temperature regulation and circulation of the asphalt to maintain the hot liquid state for easy application.

Claims

1. A method for automatically delivering hot asphalt material for application to a surface, comprising;

heating an asphalt material to a liquid state;

insulating said heated asphalt material;

pumping said heated and insulated asphalt material;

applying said heated and insulated asphalt material to a surface through a heated applying means by jet spraying said liquid asphalt onto said surface; and

rolling said liquid asphalt smooth on said surface.

2. A method for automatically delivering hot asphalt material for application to a surface as recited in claim 1, further comprising, maintaining said heating and insulating of said liquid asphalt material while pumping and applying by consistently measuring the temperature of said liquid asphalt material and regulating variations in the temperature of said liquid asphalt material from a specified range.

3. A method for automatically delivering hot asphalt material for application to a roof surface, comprising:

heating asphalt material to a liquid state in a large vessel;

pumping said asphalt material into a smaller heated storage tank through heated and insulated means for maintaining said liquid state of said asphalt material during pumping;

positioning said large vessel at ground level and said smaller heated storage tank at roof level and wherein said asphalt material is pumped automatically from said large vessel at ground level to said smaller heated storage tank at roof level;

maintaining said asphalt material in a liquid state in said smaller heated storage tank;

pumping said asphalt material from said smaller heated storage tank into an asphalt hand applicator means through another heated and insulated means for maintaining said liquid state throughout said pumping;

applying said asphalt material to a surface by utilization of said asphalt hand applicator means ending with a heated jet spraying applying means; and

rolling said asphalt material smooth.

4. A method for automatically delivering hot asphalt material for application to a roof surface as recited in claim 3, wherein maintaining said heated asphalt material is accomplished by consistently measuring the temperature of said heated asphalt material and regulating variations in the temperature of said heated asphalt material.

5. A method for automatically delivering hot asphalt material for application to a roof surface as recited in claim 3, further comprising, circulating said asphalt material between said large vessel and said smaller heated storage tank to keep said asphalt material heated and in a liquid state.

6. A method for automatically delivering hot material for application to a surface, comprising;

heating a material to a liquid state;

insulating said heated material;

pumping said heated and insulated material;

applying said heated and insulated material by jet spraying said heated and insulated material; and

rolling said heated and insulated material smooth.
