This asphalt calculator determines the amount of asphalt needed for whatsoever asphalt highway or airfield projection. This calculator tin likewise piece of work equally a blacktop calculator, to decide the required asphalt for an asphalt driveway project. You can also use this calculator every bit an cobblestone driveway cost estimator, to help you take an thought how much does an cobblestone driveway price. This calculator tin be used for whatsoever asphalt project, including the repair of potholes in an asphalt roadway, or any asphalt pavement repair works. If yous're planning to brand a concrete driveway, y'all can check our concrete driveway computer for the materials you lot'll need for your project. But, if you're actually into cobblestone, continue reading to learn what asphalt is, what cobblestone is fabricated of, also every bit the benefits of building an asphalt driveway.

What is cobblestone and what is asphalt made of?

Asphalt, or asphalt concrete, is a paving cloth made out of aggregates and a binding substance called bitumen. Bitumen is a black, sticky, petroleum-based liquid that coats and bonds the aggregates together. Cobblestone concrete is considered flexible when cured, unlike cement concrete that is rigid and hard. Cobblestone physical mixtures with high amass-to-bitumen ratios are commonly used for driveways, parking lots, and residential roads. We telephone call this cobblestone mixture blacktop. Blacktop is less durable than regular asphalt concrete, but is still durable plenty for the mentioned applications. In render, blacktop is bachelor at a lower toll than regular asphalt concrete.

💡 Asphalt is one of the most common materials we utilize to build roads. In particular, planning the transition between 2 sloped roadways may be a challenge. For that reason, we created the vertical curve computer. Exist sure to accept a await at it!

How to determine your asphalt requirement?

For small projects, like repairing a pothole or a small patch in your asphalt driveway, you can purchase asphalt in buckets or bags. Potholes are unsafe, and we should prepare them equally soon as possible to avert their growth and whatsoever accidents they may cause. For larger projects, you tin guild asphalt from your local supplier. Merely, before contacting your local asphalt dealer, make sure yous already know the full weight of cobblestone you will need.

Determining the required weight of the asphalt needed is every bit elementary every bit obtaining the volume of the required asphalt and multiplying it to the density of the specific asphalt yous plan to use. Using our cobblestone estimator, you can easily make up one's mind the volume of asphalt by entering the length and width of the surface area yous program to pave with asphalt, as well as the required thickness of the pavement. Our cobblestone reckoner will multiply these values together to obtain the book of the cobblestone for your project. If y'all will exist roofing an area with shapes other than a uncomplicated rectangle, you can apply our square footage reckoner to help you calculate the total area of your project.

Now that nosotros know the volume of asphalt needed, we can determine the actual quantity of the asphalt required in terms of weight by multiplying the calculated book with the density of the cobblestone. Asphalt density ranges from 2,200 to 2,400 kg/m³ (or approximately 138 to 150 pcf). The higher the density of the asphalt, the more durable it is. In our cobblestone calculator, we used 2,400 kg/thou³ every bit the default density to requite a conservative estimation. You can, however, change this value by going to our estimator's Advanced mode. If y'all want to acquire more near the densities of concrete materials, yous might desire to cheque out our concrete weight calculator, as it gives some typical concrete densities.

Notes to consider when applying asphalt

Equally with the installation of whatsoever other construction material, the improper installation of cobblestone tin can cause bug in the hereafter, and could shorten its lifespan also. While climate and weather will naturally affect the longevity of our pavements, at that place's a lot we can do to ensure it lasts equally long every bit possible:

Start with a nicely packed base material, such as crushed stones, and subgrade textile, like gravel and sand. Having a stable area to install the asphalt onto will reduce the possibility of future asphalt settlement, and pool formation. Y'all might want to check out our gravel driveway calculator to get a glimpse of how to set up a gravel or crushed stone surface.
Clear the expanse of large and minor debris, like stones, rocks, and twigs. This debris could affect the quality of asphalt pavement, every bit they may hinder the proper compaction of the asphalt.
It would also exist excellent practice to spray some herbicides onto the area if there are traces of weeds or plants. Weeds could grow through the asphalt and could potentially crack the surface.
Compact the asphalt well, equally this volition aid avert water infiltration, and ensure the proper bondage of the aggregates. This will minimize the risk of whatever hereafter water damage.
When repairing, utilise an asphalt bitumen sealant to the edges of the newly installed asphalt to create a seamless transition from the old cobblestone pavement to the new.
For smaller areas, like asphalt driveway, terminate it off with an cobblestone sealer afterward the asphalt cures for additional durability.

If you plan to rent a consummate service from your local asphalt contractor, they could likely help you with all these tasks, merely they volition accuse. You lot may as well incur a commitment charge on the delivery of the asphalt, also every bit paying for the bitumen sealant. So, it is a good practice to talk about these things with your available suppliers so you can compare their prices to decide which supplier offers the best deal. With this cobblestone estimator, you tin can determine how much information technology would cost if yous already knew the toll of asphalt per unit of measurement weight.

How much does an asphalt driveway cost

The cost of asphalt per weight ranges from around $80 to $200 per tonne. The price depends on your location, the quality of the asphalt you wish to purchase, and the electric current price of oil. Every bit mentioned earlier, blacktop costs less than regular asphalt concrete because blacktop uses less bitumen in the mix. To determine the total asphalt cost for your project, all you lot need to do is to multiply the total asphalt weight required by the price per weight of the asphalt yous are purchasing.

Equally a sample computation of how much an asphalt driveway would cost, let usa consider a driveway that is 7 meters long, half-dozen meters wide, and 5 centimeters thick. Suppose we need to peak the driveway with a 2,300 kg/yard³ cobblestone, we can calculate the full weight of the cobblestone needed as follows:

Weight = length * width * thickness * asphalt density

Weight = 7 meters * vi meters * 5/100 meters * two,300 kg/one thousand³

Weight = four,830 kg or 4.83 tonnes

Later obtaining the required weight, we tin can at present finally calculate the total asphalt price by multiplying the required weight past the cost of the asphalt per unit of measurement weight. Let'due south say that the average price of asphalt we got from several suppliers is $120.00/tonne. We can find the total asphalt cost for our given driveway project every bit follows:

Total asphalt cost = weight * asphalt toll per weight

Total asphalt cost = four.83 tonnes * $120.00/tonne

Full asphalt toll = $579.sixty

Some advantages of using asphalt

Bated from asphalt being like shooting fish in a barrel to install, asphalt as well offers a lot of other benefits as a paving material. If properly installed, asphalt can have a lifespan of up to twenty years, and information technology would notwithstanding await beautiful with its make clean, nighttime expect. It is also a silent pavement to drive on, even at loftier speeds, which makes it the better material to use for highways and airfields. Asphalt also has high waterproofing adequacy, making it the preferred choice in freezing climates.

However, if you lot were aiming for water permeability, pavement patterns, or even a colorful kind of paving material, you lot might want to check out our paver figurer. At that place y'all will be able to make up one's mind the number of paver blocks to use for your driveway, patio or sidewalk project. You tin purchase paver blocks in different colors, and you tin can install them in a diverseness of patterns.
