The weight of asphalt can vary depending on its density, but a common estimate is that asphalt weighs about 145 pounds per cubic foot. Given that one inch of asphalt covers an area of one square foot, it would weigh approximately 12.1 pounds per inch. However, this can vary slightly based on the specific type and mix of asphalt used.
The short answer would be 1/4 to every inch.
Any number that you like: it depends how high the asphalt is stacked!
The amount of square feet in a ton of asphalt will depend on the thickness of the asphalt. If the asphalt is three inches thick it will have to cover the area three times. The type of asphalt used is also a factor towards weight.
Asphalt installation is usually bid by the square yard, the installer will buy asphalt by the ton, and it will be delivered in a truck measured in cubic yards. Therefore, a volume/weight/area ratio is required. In short, an estimator will typically assume that one square yard of compacted asphalt laid one inch deep will weigh approximately 111 pounds.
In Pensacola, FL the mixing plant is currently charging $70 per ton for SP12.5 and about $67 per ton for SP9. Prices link with oil obviously. You can search for asphalt calculator to get a conversion from yd to ton. Materials are priced by weight.
The asphalt itself is, but if there are any cracks in as seems common, then water will get under. Cracks in asphalt can be sealed easily now with many good caulk products.
There is a company called APC, The Asphalt Paving Company. Other companies providing the same service are John R. Hulrley Asphalt, Avery Asphalt, Asphalt Coatings Company, Seal Coat Specialties. There are many others located in Colorado.

Cold Mix Asphalt is a mixture of aggregate and asphalt. Cutback asphalt is a liquid asphalt. Cold Mix Asphalt is a mixture of Aggregate and Asphalt. The Asphalt is usually am emulsion asphalt or a cutback asphalt. An emulsion asphalt is asphalt cement blended with water. Cutback asphalt is asphalt cement blended with a fuel oil, kerosene, or a naptha. The water, fuel oil, kerosene or Naphta evaporates and leaves the asphalt.
You needed to specify to what depth the asphalt is being laid.
The answer depends on how deep you want the asphalt layer to be!
