Abstract
Abstract The reinforcement of soil to prevent erosion or strength loss, for examplen berms and embankments, involves the addition of fibers having an adhesive coating to the soil. Both natural and synthetic fibers may be used. Degradable or non-degradable adhesives may be employed with a preferred adhesive being one which is moderately soluble in water.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
49 words
A method of soil reinforcement, comprising: providing at least one fiber; coating said at least one fiber with an adhesive material; mixing said coated at least one coated fiber with the soil, thereby adding strength and cohesion to the soil and reducing erosion and shear failure in the soil.
Claim 2
Independent Claim
49 words
A method of soil reinforcement, comprising: providing at least one fiber; coating said at least one fiber with an adhesive material; mixing said coated at least one coated fiber with the soil, thereby adding strength and cohesion to the soil and reducing erosion and shear failure in the soil.
Claim 3
Dependent Claim
31 words
The method of claim 1 wherein said at least one fiber consists of a relatively long, single fiber and said step of coating comprises coating said fiber with a degradable adhesive.
Claim 4
Dependent Claim
31 words
The method of claim 1 wherein said at least one fiber consists of a relatively long, single fiber and said step of coating comprises coating said fiber with a non-degradable adhesive.
Claim 5
Dependent Claim
31 words
The method of claim 1 wherein said at least one fiber comprises a plurality of natural organic fibers and said step of coating comprises coating said fiber with a degradable adhesive.
Claim 6
Dependent Claim
31 words
The method of claim 1 wherein said at least one fiber comprises a plurality of natural organic fibers and said step of coating comprises coating said fiber with a non-degradable adhesive.
Claim 7
Dependent Claim
31 words
The method of claim 1 wherein said at least one fiber comprises a plurality of synthetic organic fibers and said step of coating comprises coating said fiber with a degradable adhesive.
Claim 8
Dependent Claim
31 words
The method of claim 1 wherein said at least one fiber comprises a plurality of synthetic organic fibers and said step of coating comprises coating said fiber with a non-degradable adhesive.
Claim 9
Dependent Claim
36 words
The method of claim 1 wherein said at least one fiber comprises a mixture of a plurality of natural and synthetic organic fibers and said step of coating comprises coating said fiber with a degradable adhesive.
Claim 10
Dependent Claim
36 words
The method of claim 1 wherein said at least one fiber comprises a mixture of a plurality of natural and synthetic organic fibers and said step of coating comprises coating said fiber with a non-degradable adhesive.
Claim 11
Dependent Claim
17 words
The method of claim 1 wherein said at least one fiber comprises a plurality of inorganic fibers.
Claim 12
Dependent Claim
12 words
