Russ: there are a couple of options here I think. If the asphalt chunks you have are stockpiled, then a portable crusher could be brought in to size the material to useful dimensions. The problem here is you have to get a portable crusher--a common item but not a typical machine found at a rental store. You also have to have a loader to feed the crusher, and then the crushed material will need transported and distributed on your road. After that, you'll probably need to grade out the crushed asphalt and compact it.

The next option would be to load out and distribute the big chunks as evenly as possible on your roadway. This will require a loader. Then rent, or better yet, find a contractor with a vibratory drum-type sheepsfoot roller. The sheepsfoot with the vibrator will pretty much crush-up the big chunks in place. A contractor will have the means of transporting a large compactor and will have an experienced operator to furnish. This will save on crusher costs and costs to feed the crusher. The problem you will encounter with this latter method is that the compactor will really sock down the asphalt and there will be highs and lows left in the grade. There really is no good way to evenly distribute such large chuncks of asphalt unless you lay them in like you were installing floor tile.

You may have to get a grader to peel off the compacted high spots. Graders are pretty tough and are capable of this. Then you will want to do a final pass with a smooth drum roller.

I just thought of another option. Distribute the chunks on your roadway. Get a dozer of sufficient size and "track in" the chunks by going over them multiple times. The dozer's weight and grouser ought to size up the chunks. Any remaining highs and lows can be taken out with the blade. Follow up with a compactor.

A neighboring township had demolished asphalt like you have distributed on a township road. Their chunks weren't as large as you have, but the method they used was the same. They did, however, topcoat the crushed/compacted asphalt base with chip & seal. This was a wonderful fix to a road that had perennial soft spot and pothole problems.
