What is the weight needed to apply asphalt at approximately 1/8" thick?

To determine the weight needed to apply asphalt at approximately 1/8" thickness, it is essential to understand the density and volume of asphalt. Asphalt generally weighs around 10 to 12 pounds per square foot for every inch of thickness. Therefore, when calculating for 1/8" thickness, which is 1/8 of an inch, you would take an average weight and scale it accordingly.

Typically, for a 1-inch thickness, the coverage would be around 80 to 100 pounds per square. Dividing this by the thickness in inches—in this case, 1/8” (or 0.125)—calculates to about 60 pounds per square for a 1/8" application of asphalt. Thus, the recommended weight of approximately 60 lbs/sq aligns with well-established guidelines for proper installation, ensuring adequate coverage and performance of the asphalt layer.

The other options do not match this calculation. Weights that are too low (like 50 lbs/sq) would likely result in insufficient coverage and possible performance issues, while those that are exceedingly high (like 70 lbs/sq and 80 lbs/sq) may yield excessive weight, leading to potential structural concerns and waste of materials. Hence,
