Claim:
An apparatus for collecting a volume of hardening concrete washout material from a vehicle, comprising: a portable, constructed container having a plurality of constructed walls with a plurality of respective inner wall surfaces and also having first and second ends; said second end comprising an opening; said plurality of constructed walls comprising a pair of opposing side walls extending between the first and second opposite ends, and a bottom; said container having a substantially open and uncovered top; a volume of concrete washout material in a hardening condition located within the container; at least a portion of said inner wall surfaces comprising a release material which is resistant to the adherence of the volume of concrete washout material when said concrete washout material is substantially hardened within the container; a door coupled to the second end of the container and that is adjustable between open and closed conditions; wherein the closed condition is configured to cover the opening; wherein the open condition is configured to allow the volume of concrete washout material to be emptied from the container through the opening; and wherein the container is configured in a manner such that the volume of concrete washout material in the substantially hardened condition is separated from the release material and emptied from the container through the opening at the second end under the weight of the hardened concrete washout material by opening the door at the second end and tilting the container with the first end above the second end.
