Method of Mixing Crosslinking Blends in Totes for Use to Crosslink Polymer Modified Asphalts

摘要

A method of mixing a crosslinking blend in a portable tote for use to crosslink polymer modified asphalts. The method includes providing a portable tote, where the tote includes a tank having a sidewall, a top and a bottom portion. Fixedly positioned partially within the tank interior is an air mixing system that includes a hollow wand that has a distal and a proximal end. The proximal end of the wand exits the tank. The distal end of the tote is connected to at least one accumulator plate, where the accumulator plate is adjacent to the interior bottom portion of the tank. Stored in the interior of the tank is a crosslinking blend suitable for use to crosslink polymer modified asphalts. The method includes the steps of attaching a pulsed gas controller to the proximal end of the wand and coupling a source of compressed gas to the controller, then activating the controller to cause mixing of the crosslinking blend by pulsing gases into the crosslinking blend for a sufficient period of time. After, or during mixing, the crosslinking blend is discharged from the interior of the tank, and the controller is removed from the wand, leaving said wand attached to the tank.
