Pothole repair product and mobile apparatus and method of manufacturing an asphalt patch
First Claim
1. A mobile apparatus for the repair of potholes on roadways, said apparatus comprising a motor vehicle on which is mounted a first storage bin for the containment of asphalt particles of a predetermined size range, the first storage bin having a heater for pre-heating the asphalt particles;
- a first conveyor for conveying said asphalt particles from said first storage bin to an inlet end of a heated transport mixing conveyor, a second storage bin for the containment of stone aggregate of a predetermined size range, the second storage bin having a heater for pre-heating the stone aggregate, a second conveyor having a radiant heating jacket for conveying and pre-heating said stone aggregate for delivery to said inlet end of said heated transport mixing conveyor, the first storage bin, the second storage bin and the heated transport mixing conveyor being independently heated, an asphaltic oil reservoir having a pump at an outlet thereof for feeding a predetermined quantity of said asphaltic oil at said inlet end of said heated transport mixing conveyor;
said heated transport mixing conveyor having conveying means for displacing, mixing and heating said stone aggregate, said asphalt particles and said asphaltic oil to produce an asphalt patch material and feeding same to a dispensing outlet of said mixing conveyor; and
control means for controlling the operation of said first and second conveyors, said pump and said heated transport mixing conveyor.

Abstract
A mobile apparatus for the repair of potholes in an asphalt paved surface comprises first storage bin for the containment of recycled shingle particles or recycled asphalt or combinations thereof. A first conveyor is provided for conveying the particles from the first storage bin to an inlet of a radiant heated transport mixing conveyor. A second storage bin is provided for the containment of stone aggregate. A second conveyor conveys and pre-heats the stone aggregate to the inlet of the transport mixing conveyor. An oil reservoir has a pump at an outlet thereof for feeding a predetermined quantity of asphaltic oil at the inlet of the mixing conveyor. The mixing conveyor has vanes for displacing, mixing and heating the stone aggregate, the recycled asphalt particles or recycled asphalt and the asphaltic oil to produce an asphalt patch material and feeding same to a dispensing outlet.

13. A method of manufacturing an asphalt patch material on a mobile vehicle and using recycled asphalt products in particle form, such as asphalt shingle particle or recycled asphalt for patching potholes on roadways, said method comprising the steps of:
-
i) storing in a first storage bin recycled asphalt particles of a predetermined size range or recycled asphalt or combinations thereof on said mobile vehicle, ii) storing in a second storage bin a stone aggregate of a predetermined size range on said mobile vehicle, iii) independently pre-heating at least a portion of said recycled asphalt particles or recycled asphalt and said stone aggregate in said first and second storage bins, respectively, iv) providing a heated transport mixing conveyor having an inlet end and a dispensing outlet, v) conveying said pre-heated recycled asphalt particles or recycled asphalt to said inlet end of said mixing conveyor, vi) conveying said pre-heated stone aggregate to said inlet end of said mixing conveyor for discharge simultaneously in said inlet end with said recycled asphalt particles or recycled asphalt in a predetermined ratio, vii) simultaneously with steps v) and vi) feeding an asphaltic oil from an oil reservoir on said mobile vehicle to said inlet end of said mixing conveyor in a predetermined ratio, and viii) operating said heated transport mixing conveyor to displace, mix and heat said stone aggregate with said recycled asphalt particles or recycled asphalt or combinations thereof and said asphaltic oil to produce said asphalt patch material and feeding same to said dispensing outlet for use in patching said potholes. - View Dependent Claims (14, 15, 16, 17, 18)
