Cool find. My town is actually planning a complete street tearout in the spring. All the streets were bring with asphalt over top. They are going all the way down to dirt before they pave again. Can't wait to see what people dropped through those brings 200 years ago.
Sidewalk demo's are different though. Since they only carry the weight of pedestrians, then they do not need this extensive compaction layer under the concrete. Thus old town sidewalks were often laid RIGHT ON TOP of the original native dirt or wood walks. With zero preparation or fill base. Or an inch of sand at most. But asphalt and streets are a different beast.
Boy do I know that well.And it is not very often that they EVER need to rip out the prior generation's DG layer. Because it's only the surface that has the potholes, the cracks, etc.... And no need to "re-invent the wheel" for the sub-base layer. No need to add expense. So they nearly always only ever grind down to the DG, and not lower to *true* native soil. I've seen only one or two old-town district exceptions to this rule. Where, yes, got some coins in a street demo. But for all the rest, it's as I say : Not what we're looking for.
Thank youNeat find. It looks old.
Thank youThat is a cool relic! Congrats, Jon.
..... And for what Tom stated they actually dug the main street deep to install a new sewer system. It was there I found a few old artifacts. ...
So true Tom, I ran into fill issue on parts of this tear out this summer. Sidewalks were a dream come trueBe aware that even though what you see (after the asphalt is ripped or grinded off the top) might LOOK like native soil, yet it's likely fill dirt decomposed granite layer. Ie.: The compaction base that was put there, 40 or 50 yrs. ago (whenever the asphalt streets first installed). Streets that have to support the weight of heavy vehicles are not simply laid right-on-top of native dirt, when they were engineered and designed. Instead there is a layer of this compaction bed fill material, and THEN the asphalt is laid on top of that.
And the looks of that lower level/layer can be deceiving. To the casual observer, it might *look* like native dirt. But if you are very versed in what your area's native dirt should look like , and what this D.G. layer material looks like, you can spot the difference.
I work in the street sweeper industry, that is involved in a lot of road construction (tearouts & re-paving). So I am very familiar with this.

Not sure what it came off of. I’m guessing clothing articles of some sort., I’ve been looking at different photos online to see. I did a reverse image search, it brought up an old listing from E-bay. Listed for 50 dollars. Thanks for the interest. Happy HuntingThat's a unique buckle design (and it even has a patent date)! Any idea what type of item it was originally attached to?
Street tear outs vary for sure. Was a lot of brick streets that were replaced and working on them i eyeballed some coins.....
........ DG = Desturbed ground i take it?
