How is tarmac installed?
When it comes to tarmac installation it’s important to choose the best people for the job; being experienced and professional contractors as they have the best equipment. When choosing a contractor make sure you look into their background checking out previous work they’ve carried out and reviews and testimonials they have.
During the installation process they will begin with removing the current surface or drive, clearing the ground thoroughly to ensure none of the previous drive is left behind. In order to achieve the right type of drainage so your drive doesn’t collapse or end up heaved, the installer will ensure the ground has been graded so that it slopes to the sides or bottom, so that water can drain away easily and correctly. To ensure where the water runs they will test water flow using a hose pipe so if if the water runs away how it should.
Once an appropriate slope has been created the ground will be compacted this can be done in a variety of ways although the most popular way is by a twin drum roller. When the ground has undergone compacting the base soil will be covered with coarse and jagged rock, the amount of the rock will depend on the type of soil your ground is, this is a crucial part in the drainage process.
The crushed rock ground will then be packed with subsoil. The size of the aggregate used to create the asphalt usually ranges from ½ inch to ¾ inch. Smaller aggregate is usually used for residential driveways as it gives a smoother appearance, the large the aggregate is the stronger the tarmac is. The best layer of thickness is usually 2 to 3 inches. The tarmac will then be laid, and compacted with a heavy roller and formed at a 45 degree angle at the edges.
Different colours etc..
The great thing about using tarmac is the customisation of it, it can be edged and is available in a range of colours. With a huge range of colours to choose from including the traditional black you can now choose from a range of other colours such as blue, green, red and many more. To give it a more finished and detailed look, especially popular with residential drives they can now be edged with stones and bricks to give them a better overall finished look.
