Performance grade asphalt repair composition

Abstract

The present invention is a system for repairing asphalt. The system includes a discrete quantity of an asphalt repair composition located within a container and an induction heater. The composition is a combination of an asphalt binder, aggregate particles, and induction particles. The average diameter of the induction particles ranges from approximately 10% above to approximately 10% below an average diameter of the aggregate particles used in the composition. The induction heater heats the composition within the container by generating a magnetic field that penetrates the container. The magnetic field creates eddy currents in the induction particles. These eddy currents in turn heat the composition. Because the induction particles are distributed throughout the composition, the composition heats rapidly.

What is claimed is: 
     
         1 . A discrete quantity of an asphalt repair composition, comprising:
 an asphalt binder;   a plurality of aggregate particles having an average diameter; and   a plurality of induction particles, wherein an average diameter of said plurality of induction particles ranges from 10% above said average diameter of said plurality of aggregate particles to 10% below said average diameter of said plurality of aggregate particles and wherein said plurality of induction particles have an average diameter ranging from 0.002 inches to 1 inch.   
     
     
         2 . The composition of  claim 1 , wherein said asphalt binder includes at least one mineral filler. 
     
     
         3 . The composition of  claim 2 , wherein said at least one mineral filler is selected from the group consisting of: crushed aggregates, aggregate dust, hydrated lime, hydraulic cements, fly ash, loess, kiln dusts, and any combination thereof. 
     
     
         4 . The composition of  claim 1 , wherein said asphalt binder includes at least one warm mix additive. 
     
     
         5 . The composition of  claim 1 , wherein said asphalt binder includes at least one chemical anti-stripping additive. 
     
     
         6 . The composition of  claim 1 , wherein said asphalt binder is a performance graded asphalt binder. 
     
     
         7 . (canceled) 
     
     
         8 . The composition of  claim 1 , wherein said plurality of induction particles are a material selected from the group consisting of: graphite, tungsten, iron alloys, steel alloys, steel production byproducts, and combinations thereof. 
     
     
         9 . The composition of  claim 1 , wherein said plurality of induction particles comprise 1% of said composition, to 20% of said composition. 
     
     
         10 . The composition of  claim 1 , wherein said plurality of induction particles comprise approximately 1% of said composition, to approximately 10% of said composition. 
     
     
         11 . The composition of  claim 1 , wherein said plurality of induction particles comprise approximately 5% of said composition. 
     
     
         12 .- 18 . (canceled)
