Abstract

A transportation system is adapted for transporting and removing roll on/roll off containers from a trailer surface. A tractor having a fifth wheel is used to tow the trailer. The tractor carries a supplemental platform, which is placed over the fifth wheel area to permit transfer of a container from the trailer onto the platform of the towing tractor for transportation of the container to a delivery site. The container and tractor also include mating members to permit raising one end of the container relative to the other to facilitate dumping of the contents from the container while it is carried on the supplemental platform on the tractor. A specific form of container, particularly suitable for use in the transportation system, is a double walled, insulated container for carrying hot mix asphalt.

Claims

1. A method for transporting and delivering hot mix asphalt (HMA) from a production plant to a utilization site including the steps of:

providing a trailer capable of being loaded and unloaded from either end with roll-on/roll-off containers;

placing at least one thermally insulated container filled with hot mix asphalt on said trailer from one of said ends;

towing said trailer to a destination location;

transferring each said at least one container from as said ends said trailer to a delivery vehicle;

emptying the hot mix asphalt from each said at least one container on said delivery vehicle; and

returning each said at least one empty container to said trailer.

2. The method according to claim 1 wherein the step of transferring each said at least one container to said delivery vehicle comprises rolling each said at least one container from said trailer onto said delivery vehicle.

3. The method according to claim 2 further including the step of parking said trailer at said destination location following said step of towing.

4. The method according to claim 3 wherein each said at least one container is a double-walled insulated container.

5. The method according to claim 4 further including the step of providing supplemental heat to each said at least one container prior to removal of each said at least one container from said trailer.

6. The method according to claim 1 further including the step of parking said trailer at said destination location following said step of towing.

7. The method according to claim 1 further including the step of providing supplemental heat to each said at least one container prior to removal of each said at least one container from said trailer.

8. The method according to claim 7 wherein each said at least one container is a double-walled insulated container.

9. The method according to claim 1 wherein the step of transferring each said at least one container to said delivery vehicle comprises rolling each said at least one container from one end of said trailer onto said delivery vehicle, and said step of returning each said at least one empty container comprises rolling each said at least one container onto another end of said trailer.

10. The method according to claim 9 wherein each said at least one container is a double walled insulated container.
