Multigrade bitumen is a special binder which, for the same level of penetration as a conventional bitumen, has reduced thermal susceptibility. This means that it is less fragile at low temperatures and more consistent at high temperatures. The mixtures produced with this type of bitumen provide more resistance against the forming of ruts and against distress due to fatigue.

Multigrade bitumen is a chemically modified bitumen that has the properties of a hard paving grade bitumen at high service temperatures coupled with the properties of a soft paving grade bitumen at low temperatures

Multigrade bitumen are applicable to all types of bituminous mixtures and particularly to wearing courses with high traffic demands, such as slow lanes, lanes of heavy traffic, channeling lanes, motorways, toll areas, road junctions, docks and general parking areas. They are ideal for climates with a very wide temperature range.

These characteristics mean that Multigrade bitumen is an exceptional binder for roads prone to extreme service temperatures and is ideal for climates with a very wide temperature range.
