Asphalt
Asphalt is a sedimentary rock stemming from the polymerization of natural hydrocarbon and has been used as a building material for more than
5,000 years.
Asphalt was employed by many different civilizations: Sumerian, Babylonian, Assyrian, and Egyptian, in the region around the Tigris and Euphrates Rivers in the present-day Middle East.
Mastic asphalt or hot rolled asphalt are made by blending bitumen, calcium carbonate filler, gravels and sand.
Calcium carbonate filler in asphalt acts as a sand modifier to improve the mechanical resistance of the mixture. It provides cohesion to the bitumen and improves workability.
Added fillers: components of mastic asphalt may be produced from crushed natural rock material such as limestone.
Whatever their origin, fillers must comply with the European standard
EN 13043 or any local standards.
Bitucarb® is an industrial product obtained by milling and screening. It reinforces the structure of mastic asphalt and reduces the voids from 0 to
100 µm. It also increases rheology. Asphalt must be very fluid; this improves handling.
