Abstract
Official abstract text for this publication.
This invention is in the field of road construction as it relates to improving the quality and lifetime of asphalt roads and pavement surfaces. The invention relates to methods and compositions utilizing co-polymers in combination with soil to form improved subgrade soil binder compositions for supporting asphalt roads and pavement surfaces.
First claim
Opening claim text (preview).
We claim: 1. A method of stabilizing a soil layer below asphalt-based pavements comprising; a) providing; i) a co-polymer soil subgrade binder of the formula: wherein the relative proportional range of m, p, and q are m is at least ⅓, p=0 to ⅔, q=0 to ⅔, and ii) soil; and b) treating said soil with said co-polymer soil subgrade binder so as integrate said binder with said soil to form a mixture, wherein the m, p, and q proportions of the co-polymer soil subgrade binder are varied within the range to suit the anionic/cationic/neutral composition of said soil. 2. A method of stabilizing a soil layer below asphalt-based pavements comprising; a) providing; i) a co-polymer soil subgrade binder of the formula: wherein the relative proportional range of m, p, and q are m is at least ⅓, p=0 to ⅔, q=0 to ⅔, and ii) soil; and b) treating said soil with said co-polymer soil subgrade binder so as integrate said binder with said soil to form a mixture, wherein said treating step comprises mixing said soil with an aqueous solution containing said co-polymer, wherein said co-polymer content per dry weight of soil is between 0.1 and 10 percent.
