Mastic Asphalt is a bituminous design mix containing ingredients bitumen, coarse aggregate, fine aggregate and filler material. It is working as a waterproofing material and used as wearing course for a whole range of construction work of roads and bridges. It protects structural concrete and flexible pavement top from wear and tears due to environmental impact. Percentage of bitumen content consider for the design of mastic asphalt is preferably 14 – 17%. Nowadays it is also used for roofing, tanking and flooring to avoid seepage of water.

Mastic asphalt (MA) is a dense mixture consisting of coarse aggregate, and/or sand, and /or limestone fine aggregate, and/or filler and bitumen, which may contain additives (for example polymers, waxes).The mixture is designed to be of low void content. The binder
content is so adjusted that the voids are completely filled and that even a slight excess of binder may occur. Mastic asphalt is pour able and able to be spread in its working temperature condition. It requires no compaction on site.

History of Mastic Asphalt.
Mastic Asphalt is one of the oldest construction products, and the oldest waterproofing and road surfacing material, in use for centuries. Mastic Asphalt was the first asphalt mixture used for road pavements. Hand-laid Natural Rock Asphalt was first applied successfully as a covering for footways in Paris in 1835. A material that can boast a history dating back to Greece a thousand years ago, the product was patented for use in Britain & Ireland by Richard Claridge in London and Dublin in 1837 & 1838 and the natural rock mastic asphalt became known as Claridge’s Patent Asphalt.
