The Importance of Tarmac Layers

 Tarmac Layers

If you are involved in the laying of asphalt pavement or if you are responsible for the maintenance and upkeep of the same, then you must be aware of tarmac layers. In simple terms, tarmac refers to the concrete layer that is used on the outside of the paved area.

While it is used mainly for the purpose of protecting the motorist from injury, understanding the types of tarmac and their make-up will help you decide what options are best for your paving needs.

There are three primary tarmac layers that you will come across when you visit different asphalt pavements or parking lots. These tarmac layers are the concrete slabs, the rubber/paper liner, and the gravel that are spread on the tarmac by professional tarmac contractors.

All three play a vital role in the successful maintenance and upkeep of the current and future parking lot surfaces that you have in place today.

In order to understand tarmac layers, you first need to understand how the layer helps keep you and your vehicle safe. Most vehicles encounter drainage problems at one point or another.

Whether these drainage issues are caused by drainage problems from below the paved area or from excess water accumulating above the paved surface, the end result is the same damage to your vehicle and possibly even property.

In fact, without proper drainage, many parking lots would quickly become waterlogged and therefore unsafe to drive in.

The tarmac under and around your car serves as the main support system for your tires. Whenever you are driving on the paved surface, you are actually walking on your car’s support, and this means that any damage to the pavement that you inflict on it will be repaired at the same time that you repair the damages to your tires.

This is why you should always make sure that your parking lot is tarp-free. Now that you know the importance of tarmac layers, let’s talk about how they are installed on asphalt.

You will find that tarmac layers can be purchased in a variety of different styles, sizes and materials, and therefore you should shop around until you find the tarmac that is perfect for your planned construction project.

When choosing tarmac layers, it is important to consider all of your options. Make sure that you are aware of tarmac prices in your area, and that you get proper planning permission before laying the tarmac.

If you do not have proper planning permission for laying new tarmac, then you may be faced with the problem of having to remove and replace your asphalt before you are able to lay the new tarmac surface.

If you have a properly constructed base, you may find that removing the old asphalt is not a difficult or expensive task, but if you have poured the concrete without ensuring that the base has been properly supported, you could find yourself with a big hole in your back yard.

If you are planning to use a rubberized aggregate layer, make sure that you use a high quality aggregate that is designed to withstand weathering.

Many people choose to use a rubberized aggregate underlay when laying asphalt pavement. Rubberized aggregates are designed to resist moisture, wear and tear, and are available in a variety of different thicknesses. These aggregate layers will also resist oil, grease and other chemicals that might end up on your asphalt pavement.

If you do not want to use rubberized aggregate, you can always choose to use concrete or asphalt mixture underlay. Using asphalt mixture or concrete underlay will give your asphalt pavement the same benefits as rubberized aggregates, but it will cost you less than using the rubberized variety.
