Repsol YPF

Multigrade bitumens

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.     

Repsol YPF has recently made great efforts in carrying out research into and developing new binders which make up for the deficiencies of conventional binders in certain service conditions.   

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.   

With the addition of Multigrade bitumen, Repsol YPF has extended its range of custom-made road-surfacing products.   

These bitumens 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, channelling lanes, motorways, toll areas, road junctions, docks and general parking areas. They are ideal for climates with a very wide temperature range.
