A paved driveway offers a number of advantages over one that is made of gravel. Not only does it look better but it is also easier to maintain. It also reduces the risk that your car will be scratched by a stone. Paving a driveway is a major job and it is not cheap. Therefore you have to make sure that you know how to find the best contractor for the job. In order to do this you have to know exactly what is involved in paving a driveway so that you know what to look for in a contractor’s bid.
The most important thing that you have to look at when you are having a driveway paved is the prep work. You have to make sure that the driveway is poured on a well prepared base. This is something that you have to make sure that you discuss with your contractor. In most cases the cheapest bids that you will get will be from companies that do not do this part of the job properly. If you choose to use a cheap contractor you will find that your driveway does not last more than a couple of years.
A proper base for a driveway requires that the area be excavated to a depth of at least a foot; this is going to cost you quite a bit of money because excavating that deep is not easy. You will then need six to eight inches of aggregate put in as a sub-base. This is will support the whole driveway so it has to be done properly. The sub-base also needs to be thoroughly compacted and allow for efficient drainage of water. Make sure that any bid that you get from a contractor includes this work and that the depth and the amount of aggregate is specified in the bid.
The next part of the driveway is the base layer; this should be at least two inches thick. It is important to remember when you are getting a bid for your driveway that the bid specify that the base be at a compacted thickness of two inches. If not you may find that they pour two inches of asphalt and then compact it down to a much smaller amount. Two inches is necessary to make sure that your driveway can support the weight of your car.

After the base layer is done the final step in paving a driveway is the top layer which should be at least one and a half inches thick. The important thing here is to make sure that the proper asphalt mix is used. There are broadly speaking two classes of asphalt, class one is used for the base while class two is used for the top. There are a lot of different mixtures within the two classes and the right one will depend mainly on the climate where you live. For this you are largely going to have to trust that the contractor knows what he is doing and will use the proper asphalt. This is why you need to make sure that you work with somebody who has a lot of experience.
On last thing that you should make sure is included in the bid that you receive is the slope of the driveway to allow for drainage. You don’t want water pooling in the middle of your driveway so it should slope down from the center towards the sides. Normally a slope of a quarter inch for each foot of distance is ideal. A contractor will know the proper slope but you want to make sure that this is included in the bid so that there is no confusion.
