Abstract: Asphalt surfacing compositions and methods involving asphalt millings, water, and an amount of a polyvinyl alcohol sufficient to bind the millings such that a load-bearing asphalt paving surface is formed upon application of the composition to a material are provided.

Abstract: A supercharger control device that enables the driver of a supercharged vehicle to secure the supercharger with a keyed or other type of switch is disclosed. The supercharger control device can leave the supercharged vehicle with a significant reduction in power, making the supercharged vehicle safer overall. The supercharger control device comprises a check valve and a solenoid valve in parallel configuration with the check valve. The check valve is positioned in-line between a vacuum source and an actuator of a supercharger. The check valve maintains vacuum to the actuator of the supercharger, keeping the supercharger off-line. The solenoid valve is normally in a closed position and is in parallel communication with the check valve. Thus, when the solenoid valve is in an open position, the check valve is bypassed, restoring power to the supercharger. Further, the solenoid valve is typically activated by a switch.
