Crude Oil/ Petroleum : Naturally occurring mineral oil consisting essentially of hydrocarbons, of a very dark colour.
Polymers : Polymerisation: the reaction from which high mass molecules are formed from the bonding of low mass molecules (monomers).
Bitumens : Natural organic substance or obtained from the distillation of crude oil, based on hydrocarbons, very dark brown or black, very viscous or solid, used in construction and public works (road-coverings,…..)
Synthetic Binders : Mixture of synthetic products (oils and resins) by-products of crude oil and having the distinctive characteristic of being able to be coloured, used in the manufacture of coloured road-coverings.
Asphalt Mix : The bitumens used to make road-coverings are by-products of the distillation of crude oil and are called 'penetration-grade asphalt'.
Bitumen Emulsions : Suspension of bitumens in an aqueous phase made up of water and emulsifiers.
Cutback Bitumens : Asphalt binder composed of bitumens and special oils, by-products of the distillation of crude oil. Contrary to emulsions used at low temperatures (less than 80°) cutback bitumens unmodified by polymers are used at an ambient temperature of 150°.
Polymer Modified Bitumens : Homogenous mixture made up in the most part of petroleum bitumen modified by one or several polymers. These polymers have either elastic properties (elastomers) or plastic properties (plastomers).
Asphalt Mix : The polymer modified bitumens used in the making of road-coverings are usually made up of petroleum bitumens and polymers possessing elastomeric and thermoplastic properties.
Elastomeric Bitumen Emulsions : Asphalt binder used cold or at a low temperature (max. 80°) in which the binder is made of an elastomeric bitumen (a polymer with elastic properties).
Elastomeric Cutback Bitumens : Mixture of bitumens modified by elastomers (polymers with elastic properties) and special oils,by-products of crude oil. Contrary to emulsions used at low temperatures (less than 80°), cutback bitumens modified by polymers are used at an ambient temperature of 150°.
Sealing Compound : Polymer modified bitumens in which the quantity of polymers is significantly higher than in other asphalt binders. These polymers are generally elastomers. The sealing compounds are intended for the making of superficial seals in cement concrete road coverings.
Synthetic Binders modified by polymers : As for the crude oil binders, the polymers used to modify synthetic binders give them specific thermoplastic properties, adapted to different uses.
Mix / Coating : Synthetic binders modified by polymers used in the making of coloured road coverings giving them bright, long-lasting colours that petroleum-based bitumens are incapable of giving.
Emulsions : The emulsions of synthetic binders modified by polymers are used in the making of thin, coloured road-coverings made cold and known as 'slurry surfacing'. These emulsions are also used for the re-jointing of paving slabs of natural stone.
Sealing Compound : The light sealing compound (Masse M.S.C.) is a special product. It is composed of synthetic binders modified by polymers with elastomeric thermoplastic properties so the quantity is significantly higher than in other asphalt binders made from the same binder. The light sealing compound is proposed for the treatment of cracks in all types of road coverings (cement concrete or bituminous materials).

Note: for high-quality printing use a landscape format.
