Abstract
Disclosed herein are formulations for, and methods of making and using compositions formulated through the use of maltenes to lower the required asphalt emulsion content for recycling and stabilization of roadway materials as herein disclosed.
Claims5
A method of using maltene compounds, comprising:
- a) determining an amount of CSS-1H required to add to a roadway material composition to achieve a predetermined unconfined compressive strength and/or a predetermined Marshall Stability for the roadway material composition, the roadway material composition consisting of virgin base material;
- b) determining an amount of maltene compounds to be added to a roadway material mixture, the roadway material mixture containing CSS-1H that is less than the amount of CSS-1H required to add to the roadway material composition in step a), the amount of maltene compounds being such that roadway material made from the roadway material mixture exhibits the predetermined unconfined compressive strength and/or the predetermined Marshall Stability of the roadway material composition used in step a);
- and
- c) adding the amount of maltene compounds determined in step b) to the roadway material mixture, wherein the amount of maltene compounds is at least 2.00% by weight of the CSS-1H in the roadway material mixture.
