Filed:

Sep 30, 1991

Appl. No.:

7/767739

Inventors:

Ronald W. Blacklidge - Gulfport MS
Timothy D. Rayburn - Gulfport MS

Assignee:

Blacklidge Emulsions, Inc. - Gulfport MS

International Classification:

B05D 310

US Classification:

427138

Abstract:

The present invention provides a method of sealing and priming a prepared substrate, such as a base or sub-base for a roadway, comprising the application of an amount of an emulsion consisting essentially of a first phase of a combination of resinous petroleum oil and an asphalt, a second phase of water, and suitable emulsifiers and stabilizers. The first phase comprises from about 0. 25% to 21% asphalt and from about 3. 33% to 33. 95% resinous oil based on the total weight of the emulsion. The second phase of water provides from about 62. 5% to 91. 5% of the total weight of the emulsion. The emulsifiers and stabilizers are from about less than 0. 16% to about 2. 5% of the total weight of the emulsion. The contemplated ratios of the first asphalt and resinous oil phase to the second water phase in the total emulsion applied to the base course are from about a 1:1. 8 to 1:11 ratio in the total emulsion.

Abstract:

The present invention provides a method of sealing and priming a prepared substrate, such as a base or sub-base for a roadway, comprising the application of an amount of an emulsion consisting essentially of a first phase of a combination of resinous petroleum oil and an asphalt, a second phase of water, and suitable emulsifiers and stabilizers, where the ratios of the first asphalt and resinous oil phase to the second water phase in the total emulsion are from about a 1:1. 8 to 1:11 ratio. The first phase comprises from about 0. 3% to 21% asphalt (or equivalent compositions) and from about 3. 3% to about 34% resinous petroleum oil (or oils with equivalent properties) based on the total weight of the emulsion. The second phase is of water which provides from about 62. 5% to about 91.
