As a kid growing up in a rural area, the town decided to pave our road using crude oil and sand. Quite simply, they used a truck to spread crude oil via a set of pipes and drilled holes. It smelled like gasoline/diesel/kerosene/ashpalt and just about every other petro-chemical you can think of. The oil was a deep brown color, guessing it came from local wells.
Anyway, the truck "oiled" the road, then the sand spreader "backed up" over spreading sand. It was a god-awful mess and as I mentioned, it stunk to high-heaven.
We were told not to drive on it. However, being a mile down the road, meant we probably would not survive walking on it!
Eventually, the lighter fractions would evaporate and sand/oil would form a very smooth "pavement". It was quite unlike today's asphalt roads with gravel. This stuff was really smooth.
It did not hold up well. Each winter, the deterioration was amazing and the potholes were legendary.
Also, the oil/sand mix got all over our cars and shoes. Where it became difficult to remove. Even the dog's paws were coated. Not good.
