# Amount of Asphalt Pavement Material Needed for a Paving Job

Working on the pavement project, especially related to asphalt, the calculation of materials needed for the work is required. This will determine the amount of asphalt needed. This will also assist on the budget needed in order to finish the work.

If the paving project is a single, perfect square or rectangle, it can be challenging to produce a reasonable estimate of the area. Dividing the pavement area into simple geometric shapes and adding and subtracting these areas to the area to be paved can be a useful method for assessing the area.

To determine the amount of asphaltfirstly is need to know the area to be paved. This may be simple if the area to be paved is the square, rectangular or constant width of the road. However, this is seldom the case since there may be bump-outs or islands in the area to be paved, the width of the road may vary, or there are culs-de-sac. This may seem to be impossible in some cases, but by dividing the pavement area into simple geometric shapes and adding and subtracting these areas, the total area to be paved can be quickly determined.

Next is to calculate the quantities. Quantities are usually specified by weight (tons) or volume (cubic yards). No matter how it is specified firstly it is needed to calculate the volume. Volume is easy to calculate since it is simply **area multiply bythickness.** One of the keys to calculating volume is to always use the same dimension. Therefore, if we measure the area in square feet, we have to convert thickness measurement to feet too.

Aggregate base and other material are often specified or purchased by the cubic yard; therefore, you need to convert cubic feet to cubic.

To calculate the weight of material needed for a project you will need to know the compacted density of the material. Density is the weight of material per volume. For example, pounds per cubic foot. The density of asphalt pavement mixtures does vary depending on mix proportions and the type of aggregate.

To determine the weight of the material, multiply the volume by the density of material which isweight One way to calculate the asphalt needed is by utilizing asphalt calculator. The asphalt calculator is available online and one good way to start with.

This explanation above is for manual calculation. It is also worth to note that there are resources to assist in calculating the amount of asphalt from the National Asphalt Pavement Association. They offer a useful resource for calculating the area of different geometric shapes on their website.

## Amount of Asphalt Pavement

In general, to use an asphalt calculator is to provides an online calculator to help initial grasp on the paving project. The calculator may also take into account the area and the depth of project and calculates the necessary asphalt tonnage based on an industry standard of 148 pounds per cubic foot.

Yet the most you will get from the Basic Construction asphalt calculator (or any other) is an estimate of needed tonnage. They do not provide an estimated cost.

An asphalt calculator can offer an early first step in assessing your pavement project – regardless of how large or small the site. But any online asphalt calculator should not be relied upon to provide any more than a simple tonnage calculation.
