Since I could not take my car up to the car show tonight, I finished an Asphalt Batch Plant I was working on for one of my customers. Don't try to figure out the mechanics of this one because I made it all up. My customer gave me some pictures of a complete plant, but due to room limitations, I had to condense it into a 14" x 10" area.

Upon further thought, I used to load out of a small plant in a town no one will ever think of. I recall two things. There was always a bit of hot apsalt coming down onto the hood and cab of the dump truck while loading under a silo.

 

The second item that will complete your plant, is a rotating pipe that is driven from the outside and has a jet engine inside one end blasting natural gas to make the paving material. If memory serves it was about... 60 feet long.

 

There are also a set of scales, several piles of rock (Across street was a Rail siding which conveyed rock out of hopper cars. And finally but not least, a pile of broken up concrete that was trucked back and dumped into one corner for breaking up and re-use (With the rebar recycled elsewhere)

Nice, modern asphalt plants (modeled and the plans!).  I opened this as I want to find

plans or an HO kit shown in a 1950-60's Model Railroader that built a small CREOSOTE plant to treat poles and ties, which I thought would be a great on line destination for a small logging operation. (I'd enlarge the HO plans and charge on)  Internet search just turned up barren creosote plant sites with the EPA digging them up. (sounds like a toxic working environment) The overview in the '50's ad doesn't give any detail, but it looks like tracks go back into manmade tunnels that spray loaded, dedicated flat cars, remotely like a brick kiln operation (with dedicated cars).

Ed,

I use ABS plastic tubing.  I buy it from Plastruct. It is much more expensive than PVC pipe that you could buy in a hardware store. The PVC from a hardware store has many scratches in it.  You will see this when you paint, unless you do a lot of sanding.  ABS tubing is very smooth.  ABS sheet in thicknesses of .010-.080 can be purchased from Plasttruct and glued directly to the tubing.  If you use ABS with the PVC piping you will have to glue it with CA type glue.  Hope this helps.   Alan

Ed,

Thank you,

The tops of the silos in this model are .020" ABS sheets cut to the diameter of the silo.

The silos are 2 inches in diameter. I actually cut the ABS sheet to 1-7/8" diameter, so it was easy to glue to the top. The silo roof is flat and I added an I-Beam stiffener accross the top. When I build tanks that have cone shaped roofs, I use .010" ABS sheets. I cut a circle the same diameter as the shell and cut a piece of pie out of it to give it the cone shape. I use a small internal strip as a backing bar to glue the cone together. That was done on the 3-inch diameter asphalt tank in the back of the model. On this tank, I simulated an insulated shell with a corrugated jacket. I glued a piece of -020" styrene that has a v-groove pattern. this was purchased from Evergreen.
