How To Calculate Asphalt Tonnage
When working on construction projects that involve paving roads, parking lots, or driveways, asphalt is a commonly used material. To ensure there is enough asphalt for the project, it is important to calculate the amount of asphalt tonnage needed before placing an order. This can be a difficult task, especially for those new to the construction industry; nevertheless, it is a crucial step that must not be ignored.
In this article, we will discuss how to calculate asphalt tonnage and the factors that affect the amount of asphalt needed for a project.
Factors That Affect Asphalt Tonnage Calculation
Before we dive into the calculation process, it is essential to understand the factors that affect asphalt tonnage. These factors include:
- Thickness Of The Surface – The amount of asphalt needed is influenced by the thickness of the surface. Thicker surfaces need more asphalt compared to thinner ones.
- Width And Length Of The Surface – The amount of asphalt tonnage required for paving is affected by the width and length of the surface. Larger surfaces that are wider and longer require more asphalt tonnage compared to smaller surfaces.
- Density Of The Asphalt – The amount of asphalt tonnage required is affected by the density of the asphalt. If the asphalt is denser, more tonnage will be required compared to less dense asphalt.
- Climate And Weather Conditions – The amount of asphalt needed may be affected by climate and weather conditions. In colder areas, thicker asphalt layers may be necessary, which could result in a greater amount of asphalt required.
Calculating Asphalt Tonnage
Now that we understand the factors that affect asphalt tonnage, let’s discuss the calculation process. There are different methods for calculating asphalt tonnage, but the most common method is using the following formula:
Tonnage = (Volume × Density) ÷ 2000
Volume = (Width × Length × Thickness)
Let’s break down the formula and understand each component.
- Volume – Volume refers to the amount of space that the asphalt will occupy. To calculate the volume of asphalt, you need to multiply the width, length, and thickness of the surface to be paved.
For instance, if the width of the surface is 20 feet, the length is 30 feet, and the thickness is 6 inches, the volume would be:
Volume = (20 × 30 × 0.5) = 300 cubic feet
- Density – Density refers to the weight of the asphalt per unit volume. The density of asphalt can vary depending on the type of asphalt mix used. The most common density range for asphalt is between 145-155 lbs/ft³.
- 2000 – 2000 is a constant value used in the calculation formula to convert the weight of the asphalt from pounds to tons.
Using the example above, let’s assume that the density of the asphalt is 150 lbs/ft³. To calculate the tonnage of asphalt required, we can use the formula:
Tonnage = (Volume × Density) ÷ 2000
Tonnage = (300 × 150) ÷ 2000
Tonnage = 22.5 tons
Therefore, 22.5 tons of asphalt would be required to pave a surface with a width of 20 feet, length of 30 feet, and thickness of 6 inches, assuming a density of 150 lbs/ft³.
It is important to note that the above formula provides an estimate of the amount of asphalt tonnage required. There may be additional factors that could impact the actual amount of asphalt tonnage needed for a project.
Why Consult A Professional Contractor When Determining Asphalt Tonnage?
For accurate calculations of asphalt tonnage, it is recommended to seek help from professional contractors who possess the required knowledge and expertise to determine the exact amount needed for a particular project. The process of calculating asphalt tonnage can be complicated, so it is advisable to consult professionals to avoid any errors. And a professional contractor considers various factors like climate and weather conditions that impact the required amount of asphalt. Consulting such a contractor can help you get an accurate calculation and determine the appropriate amount of asphalt for your project.
