A hydrocarbon mixture containing modified polycyclic aromatic compounds or modified PAC having a chemical structure of mean molecular weight ranging between 300 and 10,000, the chemical structure being represented by formula (I): (A)(PAC), wherein x and y are integers corresponding to the numbers of A or PAC units, selected such that x/y is equal to at least 1, preferably ranging between 1 and 50 and wherein A is a unit corresponding to a polymerizable monomer containing between 2 and 60 carbon atoms.

Hydrocarbon mixtures comprising modified polycyclic aromatic hydrocarbons

An emulsion consists essentially of clear binders and possibly colored pigments, and contains at least one clear synthetic binder with a softening point or ball-ring temperature (TBA), measured according to the NFT 66-008 standard, that ranges between 30 and 100&deg; C., at least one compound from the latex family, introduced in a quantity that ranges between 3 and 40% by weight of the emulsion, water, and at least one emulsifying agent

Synthetic bitumen oil-water emulsions, their preparation and their applications

An asphalt-fines matrix contains a quantity of millings that ranges between 1 and 70% of the total weight of the incorporated mineral material, mixed with a heavy grade bituminous binder, and has a stiffness modulus E*, measured at 15.degree. C. and at 10 Hz, that ranges between 9.10.sup.3 and 15.10.sup.3 MPa.

Recycled roadway material millings based asphalt-fines matrix, procedure

The use of an asphalt having a penetrability at 25.degree. C. from 0 to 20 in the preparation of a road asphalt (i.e. a mixture of asphalt and mineral aggregate) intended in particular for building and strengthening roadbeds. Wherein, the asphalt content of the road asphalt is higher than 6 wt %. Also the road asphalt having such composition.

Use of a very hard asphalt binder in the preparation of a road asphalt

An asphalt-polymer composition containing:

Asphalt-polymer compositions, process for making same and uses thereof

A modified or bridged asphalt composition. The composition can be obtained by treating at least one asphalt base with an acid-derived compound having at least two functional groups capable, respectively, of being grafted onto one or more sites located on two or more different aromatic entities of the asphalt base, so as to link said entities by bridging.

Asphalt compositions, method of preparation, and use

This bitumen-polymer composition contains:

Bitumen-polymer compositions, their method of preparation and their uses

N-substituted acrylamidines having the general formula: ##STR1## in which R.sub.1 is an isopropyl group, R.sub.2 and R.sub.3 each is hydrogen, ethyl, propyl, butyl, pentyl, octyl, or octadecyl. The acrylamidine is copolymerized with at least one ester of acrylic and/or methacrylic acid esters, and the copolymer has use as an oil additive and for the manufacture of molded articles, paints and adhesives.
