How do you lay tar on a gravel driveway?
Question:I want to pour tar on my driveway but not sure how it will set since there is gravel.
Answers:
Tar is not want you would want to use as it when it heats up, it becomes semi liquid and will make a real mess. A cutback or emulsion asphalt is what you want, probably an emulsion as it does not need to be heated to apply. Putting in on flattened and rolled, with a steel wheel roller will make a surface very much like an asphalt driveway at a fraction of the cost.
The gravel bed should help, not hurt.
Why would you even want to do this? If you think that by doing this you will end up with something like asphalt pavement, you won't. Using an asphalt emulsion will do nothing, either. Simply spraying or somehow applying tar, or an asphalt emulsion, this is what most asphalt driveway sealers are, will add nothing structurally to your driveway, and it will start coming apart as soon as you drive on it and you will end up with black gravel, and nothing more.
If you apply asphalt and then cover it with a layer of new stones, it will last somewhat longer. This is how roads were resurfaced in the past, especially country roads.
You need to realize, however, that the new surface will only be as good as the base that it is applied to. If you have any soft spots, they will show through immediately as soon as you drive on it.
That is a job best left to the professionals, from my experience.
you don't. hire somebody
