How is tarmac laid?

If you’re considering new tarmac for your property, it is really a job for professionals. The level of skill involved is quite large, coupled with the expense of getting all the right machinery and equipment and knowing how to use them all. Here’s how to get a good job for all your tarmac needs:

Although tarmac is cheap, in fact probably the most cost-effective available hardstanding, it is really only economical if you’re tarmacking a fairly large area. Most of the cost is for all the machines involved and getting them on the site. It can be worth considering clubbing together with the neighbours if there is some way in which others can also benefit from a new surface. This will make the job easier and cheaper for contractors who can pass their savings onto you.

When it comes to laying asphalt on the drive, there are several layers involved. The first layer is the foundation. A typical path would require excavation down to around 18cm. Next, a layer of sub-base consisting of crushed hardcore will be laid. It is then rolled by a road roller machine. If you have selected the edging or ornamental stones, this will be placed on both sides and supported during the laying of the tarmac.

The tarmac is laid in two layers, a base and then the upper surface known as ‘wearing’. A base layer consists mostly of aggregates that are delivered in a heated truck and once laid, the asphalt can be spread on it and levelled with a rake. Back comes the roller to compact all the layers together, and it will continue until there are no visible signs on the surface.

The upper surface contains smaller bits of aggregate, giving the appearance of a more refined surface that offers both strength and durability. If a good, professional job has been done, the driveway can be refreshed by skimming the top layer and laying an overlay of tarmac.

A new drive will be set up relatively quickly after being laid and after a few hours will be available to be used carefully. For the first week, it’s a good idea to avoid sharp braking, accelerating or turning the wheel when the car is stationary.

The best way to get a really good-looking job that will last for many years is to find a reputable company. For Tarmac Bristol, visit a site like Thornbury Surfacing, top suppliers of Tarmac Bristol.

Always check to see how long a company has been operating and ideally, ask to see samples of their recent work has been done. Do not let anyone drive your bid for asphalt had just knock on your door out of the blue. You may find yourself dealing with unscrupulous merchants who are likely to overcharge you and provide you only with a thin layer of asphalt that will not last more than a few weeks.
