Abstract
The cationic asphalt material of the present invention has minimal tracking, fast drying bonding to material and allows for quick turn around in road construction. It has been designed as a joint sealer that can be used successfully as a tack coat or fog seal. The fast drying bonding material allows plant mix asphalt to be put clown in minutes from initial application.

A composition for use in asphalt paving comprising:
- a tack coat that is fast drying with minimal tracking properties comprising:
- a. from about 40 wt % to about 70 wt % asphalt composition,
- b. from about 30 wt % to about 60 wt % water,
- c. from about 0.1 wt % to about 10 wt % latex polymer,
- d. from about 0.05 wt % to about 1.0 wt % sodium chloride,
- e. from about 0.21 wt % to about 0.5 wt % surfactant, and
- f. from about 0.1 wt % to about 1.0 wt % muriatic acid, wherein said composition is a cationic emulsion.
A method for bonding together two strips of asphalt utilizing a cationic minimal tracking tack coat comprising the steps of:
- a. laying a first strip of asphalt;
- b. applying a fast drying, minimal tracking tack coat to the first strip of asphalt, the tack coat comprising:
- from about 40 wt % to about 70 wt % asphalt composition,
- from about 30 wt % to about 60 wt % water,
- from about 0.1 wt % to about 10 wt % latex polymer,
- from about 0.05 wt % to about 1.0 wt % sodium chloride,
- from about 0.21 wt % to about 0.5 wt % surfactant, and
- from about 0.1 wt % to about 1.0 wt % muriatic acid, wherein said composition is a cationic emulsion;
- and
- c. laying a second strip of asphalt on the tack coat applied to the first strip of asphalt.
A composition for utilization in asphalt paving comprising:
- a joint sealant that is fast drying with minimal tracking properties joining two adjacent two strips of asphalt, said joint sealant comprising:
- a. from about 40 wt % to about 70 wt % asphalt composition,
- b. from about 30 wt % to about 60 wt % water,
- c. from about 0.1 wt % to about 10 wt % latex polymer,
- d. from about 0.05 wt % to about 1.0 wt % sodium chloride,
- e. from about 0.21 wt % to about 0.5 wt % surfactant, and
- f. from about 0.1 wt % to about 1.0 wt % muriatic acid, wherein said composition is a cationic emulsion.
A method for bonding together two strips of asphalt utilizing a cationic minimal tracking joint sealant comprising the steps of:
- a. laying a first pass of asphalt;
- b. laying a second pass of asphalt;
- c. applying a joint sealant between the first pass of asphalt and the second pass of asphalt, the joint sealant comprising:
- from about 40 wt % to about 70 wt % asphalt composition,
- from about 30 wt % to about 60 wt % water,
- from about 0.1 wt % to about 10 wt % latex polymer,
- from about 0.05 wt % to about 1.0 wt % sodium chloride,
- from about 0.21 wt % to about 0.5 wt % surfactant, and
- from about 0.1 wt % to about 1.0 wt % muriatic acid, wherein said composition is a cationic emulsion.
