  "title": "Pot hole filler composition and method of making same",
  "abstract": "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.",
  "claims": [
    "1. A pourable pot hole filler comprising: 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 pot hole filler of claim 1 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.",
    "3. The pot hole filler of claim 1 wherein said aggregate comprises pumice, and wherein said activator comprises calcium sulfate.",
    "4. The pot hole filler of claim 1 wherein said latex polymer comprises a synthetic rubber aqueous dispersion.",
    "5. The pot hole filler of claim 1 wherein said asphalt emulsion is anionic, wherein said aggregate comprises pumice, and wherein said activator comprises calcium sulfate, and wherein said latex polymer comprises a synthetic rubber aqueous dispersion, and wherein said composition 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."
