Robert Grover Allen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Age resistant coatings and methods for treating roadway substrates
    Patent number: 11414549
    Abstract: Aging resistant emulsified asphalt compositions and related methods of preparing and applying the same for use in asphalt treatment and paving applications. The aging resistant emulsified asphalt compositions can include an aging resistant asphalt composition, emulsifier, and water. The resulting residue formed when the emulsified asphalt composition has cured is aging resistant and can be resistant to age-induced cracking even after simulated aging of 14 years and 21 years. Appropriate use of emulsifiers in some embodiments can further improve aging resistance in the residues.
    Type: Grant

  • Age-resistant asphalt compositions and methods
    Patent number: 11401424
    Abstract: Aging resistant asphalt compositions and related methods of preparing and applying the same are provided. The aging resistant asphalt compositions can include a base asphalt with specified properties combined with an aging resistance additive, to produce modified asphalt compositions having a colloidal index within the range of about 3.7 to about 8.0, a saturates content of less than about 10% by weight, and measurable age-resistant properties. The aging resistant asphalt compositions are useable in a variety of asphalt paving and non-paving applications. The aging resistant asphalt compositions provide improved resistance to both moderate and low failure temperatures of conventional paving asphalts throughout its service life by reducing age-related failures.
