During our study of Ancient Rome, we took an afternoon and spent the time creating a mock roman road.
The first layer....sand.
Second layer--small crushed rock or gravel.
Next, a cement like substence. We used sand mixed with glue.
The last layer was large paving rocks.
By leaving a fourth of each layer exposed, we could see all the elements used to create our road I'm amazed that today, roads built over 2,000 years ago can still be used.
I agree...I always marvel at the fact that things built so long ago are still intact. And those people didn't even have technology like we have today.
