A driveway can really add to the value of your home, not to mention provide you with a place to park your car. There are several different materials that can be used to build a driveway so you are going to need to be able to determine which is best for your needs. One of the factors that you will have to consider is cost. Therefore you are going to want to know how to estimate the cost of an tarmacadam driveway.My explanation, tarmacadam driveways.
The first thing that you are going to have to do in order to estimate the cost of an tarmacadam driveway is to determine just how big your driveway is going to be. This is fairly easy to do in most cases since they are usually fairly rectangular. Even if your driveway does have a bit of an odd shape you should not find it to be too difficult to determine the square footage for your driveway. Once you have the square footage you will want to divide that number by nine in order to determine the square yardage which is what is used in the formula for estimating how much tarmacadam you will use.
The next thing that you are going to have to do is to determine how thick your driveway will need to be. The standard for an tarmacadam driveway is three inches. This normally consists of two inches of base pavement with a one inch wearing layer on top of that. If you are replacing an existing driveway you can probably just replace the wearing layer so you would base your estimates on a one inch thickness, for new construction you will need three inches.
Tarmacadam is sold by the ton and there is a formula for determining how many tons you will need for your driveway. The formula is the square yardage times the constant 0.057 multiplied by the depth of pavement in inches. Therefore if you had a driveway that was 300 square yards and three inches thick you would come up with a requirement for 51 tons of tarmacadam. The price of tarmacadam will vary depending on a number of factors, particularly the price of oil, so you will want to check the current price. If we assume it goes for $150 a ton which is about average the cost of paving your tarmacadam driveway would come to $7500.
It is important to keep in mind that this is just the cost of paving the driveway; you will also have to have prep work done before hand. In most cases you will need to excavate eight to twenty four inches depending on the climate where you live, the colder it is the deeper you will have to go. You will then need to fill that excavation with gravel and have it compacted, this is necessary to ensure proper drainage. The cost of all of the prep work will run you at least another two to three thousand dollars, even more if gas or plumbing lines have to be moved.
While you are going to want to keep the cost of the prep work in mind when you are planning your budget it is not really a factor when it comes to deciding on the type of driveway that you will have. The same prep work will be required regardless of what you build your driveway out of. You want to make sure that you don’t skimp on the base of your driveway; if it is not well built the whole thing will be poorly constructed.
