A non-tacky asphalt packet in which the surface is coated with a continuous layer of polymer compatible with the asphalt, and which has a surface-to-volume ratio which in the presence of heat makes the asphalt melt in an adequately short time such that when n dispersed in an aggregate mixture allows the asphalt to melt and coat the aggregate uniformly as the aggregate reaches the maximum mix temperature, and prior to degradation of the asphalt due to excessive temperature.

The modified high-viscosity asphalt has raw materials of a base asphalt mixture, an oil slurry, a rubber modifier, modified petroleum resin, an anti-stripping agent, and carbon black powder. The road asphalt patching tape has good high-temperature performance, excellent wear resistance to wheels, a very high friction coefficient and good low-temperature ductility. The road asphalt patching tape can be closely attached to and effectively repair the diseased road surface. In this way, the road asphalt patching tape is compactly connected to the diseased road surface, which can strengthen the diseased road surface, strengthen the overall strength of the cracked area, and prevent diseases, such as turtle shell-shaped cracks, pitted surfaces or the like, from deteriorating into potholes or the like.

The present disclosure includes systems and methods for applying a coating system to a surface. An example method includes spraying an asphalt emulsion onto a surface at a rate of between about 0.12 and 0.20 gallons per square yard, the asphalt emulsion having: an asphalt blend comprising gilsonite, wherein at least a portion of the gilsonite is modified to possess a positive charge; one or more polymers, and one or more surfactants. The method may include applying a fine aggregate onto the asphalt emulsion. The fine aggregate may be applied at a rate of 2.5 pounds per square yard. In such an aspect, the asphalt emulsion may be sprayed at a rate of about 0.18 gallons per square yard, and the asphalt emulsion may contain about 56% solid asphalt residues by weight of the asphalt emulsion. In another aspect the fine aggregate may be applied at a rate of about 1.25 pounds per square yard, the asphalt emulsion may be sprayed at a rate of about 0.17 gallons per square yard, and the asphalt emulsion may contain about 37% solid asphalt residues by weight of the asphalt emulsion.

A material composition for repairing and sealing asphalt and concrete surfaces is provided. The material composition for repairing asphalt and concrete includes an asphalt containing concentrate between about 25.0 wt. % and about 95.0 wt. %, an aggregate with amorphous aluminum silicate between about 15.0 wt. % and about 65.0 wt. % and reinforcements up to about 8.0 wt. %. The material composition for sealing asphalt and concrete includes a non-fiber asphalt emulsion between about 20.0 wt. % and about 60.0 wt. %, carbon black between about 0.5 wt. % and about 5.0 wt. %, an aggregate with amorphous aluminum silicate between about 1.0 wt. % and about 10 wt. %, a hydrophobic additive between about 0.1 wt. % and about 1.0 wt. %, and a coalescent between about 0.01 wt. % and about 0.5 wt. %.
