Abstract
Abstract The invention relates to a composition and process for grading and immediate stabilization of embankments, for example, in road, levee or canal construction. Use of a mixture of rip rap and loam permits the construction of a steeper embankment than has previously been possible with inexpensive materials and unskilled labor thereby conserving valuable space along the embankment. It also provides for immediate stabilization eliminating erosion during construction. The loam and rip rap may be premixed or, alternatively, the loam may be interjected into preplaced rip rap, for example, in a water slurry. Additional stabilization is provided due to the fact that an embankment made according to this invention will support vegetation and other plant life and ultimately result in an indestructible, interwoven stabilization medium. The planting of vegetation can be varied to suit the climate involved or the particular purpose intended, i.e., wildlife cover and food. Ultimately this process of stabilization will provide a more aesthetic end result.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
114 words
A composition for grading and stabilizing embankments by application to the surface of an embankment in depths of about 2-4 feet, as measured perpendicular to the embankment, in the absence of any artificial supporting means, which composition consists essentially of a mixture of rip rap and loam wherein said rip rap consists essentially of a mixed aggregate of processed stone ranging in size from about 6-18 inches in diameter in which at least about 25% of said rip rap is less than 10 inches in diameter and at least about 25% is greater than 10 inches in diameter, and the proportion by volume of loam to rip rap is from about 1-10 to 1-2.
Claim 2
Dependent Claim
114 words
A composition for grading and stabilizing embankments by application to the surface of an embankment in depths of about 2-4 feet, as measured perpendicular to the embankment, in the absence of any artificial supporting means, which composition consists essentially of a mixture of rip rap and loam wherein said rip rap consists essentially of a mixed aggregate of processed stone ranging in size from about 6-18 inches in diameter in which at least about 25% of said rip rap is less than 10 inches in diameter and at least about 25% is greater than 10 inches in diameter, and the proportion by volume of loam to rip rap is from about 1-10 to 1-2.
Claim 3
Dependent Claim
14 words
The composition of claim 1 wherein said rip rap consists predominantly of granite stone.
Claim 4
Dependent Claim
23 words
The composition of claim 1 wherein said loam has a total sand and clay content of not more than about 50% by weight.
Claim 5
Independent Claim
112 words
A method for grading and stabilizing an embankment comprising applying to the surface of said embankment in depths of about 2-4 feet, as measured perpendicular to the embankment, in the absence of any artificial supporting means a mixture consisting essentially of rip rap and loam wherein said rip rap consists essentially of a mixed aggregate of processed stone ranging in size from about 6-18 inches in diameter in which at least about 25% of said rip rap is less than 10 inches in diameter and at least about 25% is greater than 10 inches in diameter, and the porportion by volume of loam to rip rap is from about 1-10 to 1-2.
Claim 6
Independent Claim
112 words
A method for grading and stabilizing an embankment comprising applying to the surface of said embankment in depths of about 2-4 feet, as measured perpendicular to the embankment, in the absence of any artificial supporting means a mixture consisting essentially of rip rap and loam wherein said rip rap consists essentially of a mixed aggregate of processed stone ranging in size from about 6-18 inches in diameter in which at least about 25% of said rip rap is less than 10 inches in diameter and at least about 25% is greater than 10 inches in diameter, and the porportion by volume of loam to rip rap is from about 1-10 to 1-2.
Claim 7
Dependent Claim
14 words
The method of claim 4 wherein said rip rap consists predominantly of granite stones.
Claim 8
Dependent Claim
23 words
The method of claim 4 wherein said loam has a total sand and clay content of not more than about 50% by weight.
Claim 9
Dependent Claim
19 words
The method of claim 4 wherein said rip rap and loam are premixed before being applied to said embankment.
Claim 10
Dependent Claim
21 words

Claim 11
Dependent Claim
17 words

Claim 12
Dependent Claim
21 words
