Problems solved by technology

Unfortunately, however, the addition of retarders undesirably contributes to (a) weakening of the cementing properties of asphalt materials, (b) degradation of performance, (c) increased sensitivity of the material to water, and (d) reduced longevity of the repair

Embodiment

[0070] Cationic asphalt sealer compositions were prepared by adding the following components to water in the amounts given and in the order listed.

[0071] .

[0072] The complex modulus of the hardened sealant was 2300 kPa when the material was aged for only 4 hours before the test was started and then allowed to cure for 4 days (Composition A). The complex modulus of the hardened sealant was essentially the same when applied after 11 days of storage and allowed to cure for 17 hours (Composition B). The results are shown in the accompanying drawings.

[0073] A sealant composition comprising a polar polymer hardener (polyvinyl alcohol) was then prepared as follows:

[0074] .

[0075] When applied within 4 hours and allowed to cure for 4 days (Composition C), the complex modulus of the hardened sealant skyrocketed to 5900 kPa. However, when the composition (Composition D) was stored for 11 days, the composition settled to a point where it could not be reversed by mix...

Abstract

A method of producing a cationic asphalt slurry composition which can be used as an asphalt paving sealer or as a paving or repair composition. In the method and composition, latex and other polymers are used to build viscosity and a pH buffering filler is added to prevent flocculation. Consequently, the cationic composition can be stored without irreversibly settling or separating, and without breaking for several days prior to use. In addition, non-expansive clay and a polar polymer hardening agent are used so that, when applied, the composition will set and develop strength very quickly.

Description

technical field [0001] The present invention relates to compositions and methods for sealing roadways, parking lots and other traffic surfaces. Background technique [0002] Asphalt is known to be used to construct roads, parking lots, driveways and paths. After 3-5 years of asphalt paving, a preventive maintenance treatment, such as a sealant, will typically be applied to the paved surface to (a) seal the surface from water penetration, (b) improve the appearance of the pavement, (c) prevent oxidation of the underlying asphalt pavement, and UV damage, (d) protects pavement from oil and gasoline spills and (e) provides a surface that is easier to sweep, clean, spade and maintain. All of these benefits increase the useful life of the pavement. [0003] Subsequently, a fresh coat of sealant material is applied to the asphalt pavement surface, preferably approximately every 2-3 years. Additionally, as cracks or other hazardous areas develop in the paving surface, and especia...
