What is Mastic Asphalt?

What Is Mastic Asphalt Made Up Of?

Mastic Aspahlt is made up of limestone aggregates bonded together with either a real bitumen or a modified bitumen. Certain asphalt mixes can contain also contain Lake Aspahlt. Modified bitumen and mixes contain Lake Asphalt allow for better handling and performance.

Bonded mastic asphalt contains no voids. This makes it a perfect material for waterproofing. The way in which asphalt is normally applied in the UK is with a handmade wooden float. Asphalt can often be applied using a spatula. The use of a spatula can often be seen in Paris where French asphalt specialists prefer this method of asphalt spreading.

How Is Mastic Asphalt Made?

Mastic Asphalt is created through a batch production process. Fine and coarse limestone aggregates are bonded together with asphaltic cement. Nowadays this asphaltic cement normally consists of modified bitumen. However, some asphaltic cement will contain bitumen or a combination of bitumen with Lake Aspahlt.

The content of aggregate in this mix for most types of mastic asphalt will be 20%. But if extra hardness is needed for the application, such as a walkway or roof which will endure heavy foot traffic this aggregate content may go as high as 35%. The more aggregate added to the mix the harder the mastic asphalt will become.

The mix of aggregates with asphaltic cement are fed into a hot mixer and constantly agitated. Once a good mix has been achieved, samples are taken and tested in a lab. Once the mix passes the lab tests the mix is ready to be poured into a mould which will create numerous asphalt bricks. These bricks are left to cool off in the mould and then stored in batches before being taken to a construction site to be used to waterproof applications.

What Are The Uses of Mastic Aspahlt?

Mastic Aspahlt is commonly referred to as ‘The King of Waterproofing’. It can be used on a range of different applications. Asphalt roofing is probably the best-known use of this material. But it can also be seen used in the waterproofing of car parks, asphalt steps, flooring, tanking, bridge expansion joints, balconies, walkways and loading bays.

Mastic asphalt is truly a time tested versatile waterproofing solution which is environmentally friendly and carbon zero rated.
