How to make asphalt, take 2

[SHOZ]

They are going to chip my road again and I see Menards has the asphalt foundation sealer on sale at $8 off per 4.75 gallon pail. 5 pails should do me.

I swept the loose gravel off for use later. The base is gravel and some remaining asphalt on top of that, though it's spotty.

Going to coat the it with used oil first. Then pour down the foundation sealer and cover in gravel chips. The oil breaks the surface tension of the fine dirt at lets the asphalt stick better to the base gravel.

I believe there is still some remains of Roman asphalt in places within Europe. Or was it Roman concrete? Talk about longevity.

It depended on where the road was constructed, urban roads within Rome often used mortar or concrete but rural roads were rock with a surface of what would be akin to modern traffic bond. Always built in straight lines whenever possible.
