Tarmacadam

This is the actual name for what we mostly call ‘tarmac’. It is a tough and hard-wearing substance, great for road surfaces. It is made by coating layers of crushed stone with tar.

Bitmac

Nowadays, bitmac is the preferred choice as it is less susceptible to damage from spillages of petrol or diesel. It still contains the crushed stones but is coated with bitumen instead of tar. This makes it more similar to asphalt surfaces than tarmac, however, bitmac has more sand and filler than asphalt.

Asphalt

Popular for road surfaces as it’s economical to produce for covering large surface areas. It is not so ideal for smaller surfaces, however. Although often referred to as asphalt tarmac, the two are very different. Asphalt is tougher but not so resistant to scuffs from tyres, for example. Asphalt is more weather resistant, particularly in extreme weather and requires much less upkeep.
