Abstract
This invention relates to a process for treating cementitious containing materials including asphalt with a binding composition containing a protein-polysaccharide complex to improve resistance to erosion caused by environmental forces and physical wear and to enhance internal adhesion of the compositions. The use of the binding compositions in asphalt paving compositions reduces the amount of bitumen or asphalt emulsion necessary to produce asphalt paving compositions while increasing the wear resistance of the asphalt paving composition.
Claims48
A method of enhancing internal adhesion of an asphalt containing composition by admixing with said cementitious composition a protein-polysaccharide complex composition comprising:
- between about 90% to 99.5% by weight of a water-soluble polysaccharide impregnated with between about 10% to 0.5% by weight of a substantially water-insoluble protein in an mount effective to enhance the internal adhesion of said asphalt containing composition.
An asphalt or bitumen containing composition having improved resistance to erosion and enhanced internal adhesion comprising a protein-polysaccharide complex composition comprising:
- between about 90% to 99.5% by weight of a water-soluble polysaccharide impregnated with between about 10% to 0.5% by weight of a substantially water-insoluble protein.
A method of enhancing internal adhesion of a cementitious composition by admixing with said cementitious composition an effective amount to enhance the internal adhesion of cementitious compositions of a protein-polysaccharide complex composition comprising:
- between about 90% to 99.5% by weight of a water-soluble polysaccharide impregnated with between about 10% to 0.5% by weight of a substantially water-insoluble protein.
A cementitious composition having improved resistance to erosion and enhanced internal adhesion comprising a protein-polysaccharide complex composition comprising:
- between about 90% to 99.5% by weight of a water-soluble polysaccharide impregnated with between about 10% to 0.5% by weight of a substantially water-insoluble protein.
