Asphalt has been around for centuries and its uses have been wide ranging. In ancient times it was used as an adhesive in its raw form to bind bricks and stones and also to waterproof boats. It was (and still is) used in roofing. Artists also tried to use asphalt in paintings until they realised that it never completely hardened which was a bit of a problem for creating enduring masterpieces. It wasn't until the 1800's that using asphalt combined with aggregates became popular leading to what we know today as probably the most hard wearing and durable road surfacing we now see everywhere.

Asphalt has a number of names: asphalt, bitumen, tarmac and pitch are a few of the common ones. Other than name, they are all one and the same thing: a sticky, black and highly viscous semi-solid form of petroleum. It starts off as a naturally occurring deposit and then gets refined and processed to give us the product we use to lay asphalt surfaces. Raw asphalt needs to be heated in order to combine it with aggregates (gravel, sand and stone) to make it suitable for road and paving use.

First we chalk line the area
Then we tack coat the area to make the speed hump stick
We use steels on the edge then form the asphalt
Then we compact the speed hump and it is ready for use
Job done! After a few days it can be line marked if required.
(This speed hump was placed on top of a concreted area.)

We were surprised to find one of our recent customers not entirely satisfied with the job. When we were finished the job the customer said "Hey guys I'm not happy. The work you have done looks fantastic – now the rest of my driveway looks like sh!te. You be back here in the future to do some more!"

If you want to repair your own potholes, you can in some places buy asphalt from a hardware store. However these products are only a temporary measure and do not seal to the edges. This will allow water to get in. Only hot asphalt coats and seals properly for a durable and hard wearing surface.
