Pot hole filler composition and method of making same
A system and method for filling pot holes. The system includes transferring aggregate from an aggregate tank. Activator is likewise transferred from an activator tank. The activator is mixed with the aggregate to form a homogenized mixture. A liquid is introduced into a homogenized mixture to form a slurry and then a pot hole filler. The pot hole filler is directed through an exit end of a mixing tube.
1. A method for producing a pot hole filler, said method comprising:
a) transferring aggregate from an aggregate tank;
b) transferring activator from an activator tank;
c) mixing said activator with said aggregate to form a homogenized mixture;
d) introducing a liquid into said homogenized mixture to form a pot hole filler;
directing said pot hole filler through an exit end of a mixing tube;
wherein said pot hole filler comprises:
asphalt emulsion;
latex polymer;
aggregate;
glycol; and
an activator, and wherein said composition is a pourable slurry, and wherein said pot hole filler comprises an asphalt emulsion to latex polymer ratio of between about 1.1:1 to 1.4:1.
2. The method of claim 1 wherein said transferring of step a) and b) comprises transferring via an auger.
3. The method of claim 1 wherein said introducing of step d) comprises introducing a liquid from a liquid tank.
4. The method of claim 1 wherein said introducing of step d) comprises introducing the liquid through a liquid inlet located a mixing length upstream from the exit end.
5. The method of claim 1 wherein external heat is not utilized.
6. The method of claim 1 wherein said liquid comprises an asphalt emulsion, a latex polymer, and a urethane resin.
7. The method of claim 6 wherein said latex polymer comprises a synthetic rubber aqueous dispersion.
8. The method of claim 1 wherein said liquid comprises an asphalt emulsion.
9. The method of claim 8 wherein said asphalt emulsion is anionic, wherein said aggregate comprises pumice, and wherein said activator comprises calcium sulfate, wherein said asphalt emulsion comprises glycol, wherein said pot hole filler comprises a pourable slurry, and wherein said pot hole filler comprises an asphalt emulsion to latex polymer ratio of between about 1.1:1 to 1.4:1.
10. The method of claim 9 wherein said pot hole filler comprises between 20-49% by weight asphalt emulsion, 30-50% by weight latex polymer, 17-50% by weight aggregate, and between 0.09 and 0.38% by weight of an activator, and wherein said pot hole filler further comprises a urethane resin, wherein said pot hole filler comprises between about 0.2% to 0.6% by weight urethane resin.
