Asphalt paving concrete may be defined as a dense medium or open graded blend of crushed rock fines, mineral aggregate (course stone) and bitumen. Asphalt Concrete complies with IS EN 13108 along with NRA specifications for roadworks. It is completely aggregate based which gives the mix its strength. It can be categorised into three groups – base course, binder course and surface course.

Asphalt paving provides structural strength to the highway pavements through binder and base courses and the thickness level may be in accordance with the design. The design and thickness are determined through the projected traffic levels.

Our team of asphalt tarmac contracts will then provide an interface by the surface courses between the vehicles and designed pavement.

In highly trafficked urban streets, housing estates and car parks typically close graded asphalt concrete courses are used. On the other hand, in playgrounds, footpaths, and sports surfaces, open graded asphalt concrete surface courses are used because in these areas surface water is required to drain through the pavement.

Why Use Our Asphalt (Tarmac) Contractor Services

In accordance with EN 13108-1, asphalt paving concrete has replaced the previous references to coated macadam in accordance with BS 4987.

With different combinations of aggregate and binder, asphalt concrete materials can be used as base binder and surface courses.

From car parks, heavy duty road pavements and driveways, asphalt paving is suitable for a wide range of uses.

In order to classify the materials, a number of changes have been introduced by the European standards but in reality, the materials are the same as prescribed previously.

There is an addition to the new standard of asphalt paving. For industrial units and private driveways, there is the use of Marshal Type surface courses. As compared to the traditional macadam type surface courses marshal type mixtures have a smooth finish to withstand scuffing.

The Many Benefits of Asphalt Contractor Paving

Smooth

Asphalt gives a smooth ride to the drivers because it is the smoothest surface for driving. In fact, it makes contact with the tires more enjoyable and safer. During rainstorms, splash and spray can be minimised through open graded asphalt. This may ultimately reduce the number of crashes and fatalities on the highway.

Easy To Maintain

In order to keep the asphalt pavement in the good tip-top shape, it should be designed as a perpetual pavement. It may require only periodic maintenance checkups by our team of asphalt tarmac contractors.

Cost Effective

As there are fewer bumps on the smoother roads, there is a reduction of wear-and-tear on the vehicles. The vehicle operating costs are brought down because of the smoother roads. In fact, the smoothness of the roads can extend the lifespan of the vehicles by 25%.

Energy Efficient

There is less friction between the tires and the road because asphalt produces smoother roads. Ultimately the carbon dioxide emission of the vehicle is reduced and the fuel economy rating goes up. Asphalt can be mixed with lower temperatures at the time of construction which will definitely reduce the energy used to heat asphalt.

Minimise Disruption

Asphalt roads can be applied one at a time which signifies that only a lane or two would be closed to traffic. Disruption of business and even personal errands might be reduced.

Is There any Difference between Bitumen Surface Dressing and Asphalt?

A liquid binder when used to hold asphalt together is termed as bitumen. In a majority of the cases, bitumen surface dressing is mistakenly used to describe asphalt.

When a layer of bitumen is sprayed and covered with an aggregate, it is termed as the bitumen sealed road. To give a two coat seal, the process is repeated.

After heating, mixing and drying the aggregate, sand, and bitumen in a plant, asphalt is produced. It is then applied on the site with the help of a paving machine. At the time of spray, it is a solid material with a nominated and required thickness which is relative to the end use. As compared to the bitumen sealed road asphalt results in a smoother and more durable surface.
