Abstract
Abstract The invention relates to a soil stabilization composition comprising a rubber latex of solids content at least 40% by weight and a compatible oil which is prepared by admixing the oil and the latex in the presence of additional emulsifier and in the substantial absence of added water. The composition may be applied as such and optionally rotovated into the soil after application. If desired, a bitumen emulsion may be included in the composition.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
68 words
A process for stabilisation of soil or other particulate matter which comprises applying a composition formed from a natural or synthetic rubber latex, of solids content at least 40% by weight, and a compatible oil characterised in that the composition is prepared by admixing the oil and the latex in the presence of a non ionic surfactant as additional emulsifier and in the substantial absence of added water.
Claim 2
Dependent Claim
68 words
A process for stabilisation of soil or other particulate matter which comprises applying a composition formed from a natural or synthetic rubber latex, of solids content at least 40% by weight, and a compatible oil characterised in that the composition is prepared by admixing the oil and the latex in the presence of a non ionic surfactant as additional emulsifier and in the substantial absence of added water.
Claim 3
Dependent Claim
16 words
A process according to claim 1 wherein the emulsifier is an alkyl phenol ethylene oxide condensate.
Claim 4
Dependent Claim
27 words
A process according to claim 1 wherein the emulsifier is used in an amount of 0.5 to 10 parts per hundred parts of rubber in the latex.
Claim 5
Dependent Claim
15 words
A process according to claim 1 wherein the bitumen emulsion is included in the composition.
Claim 6
Dependent Claim
20 words
A process according to claim 1 wherein the composition is rotovated into the soil or other particulate matter after application.
Claim 7
Dependent Claim
14 words
A process according to claim 1 wherein the rubber latex is natural rubber latex.
Claim 8
Dependent Claim
15 words
