Abstract: A method for recycling or renovating old pavements, wherein a rejuvenating binder is used including at least one compound based on fatty substances of natural origin including hydrocarbon fatty chains, these fatty substances of natural origin having undergone at least one chemical functionalization reaction through which at least one oxygenated functional group has been introduced. The rejuvenating binders and rejuvenating binder emulsions especially suitable to the method, and asphalt mixes based on regenerated reclaimed asphalt pavement are also disclosed.

Abstract: The invention relates to application of solvent(s) to a product including at least one binder, wherein the product is a paint or coating formulation and the solvent is a compound of renewable vegetable origin, notably agricultural origin. It also relates to a paint or coating including at least one binder and one solvent, wherein the solvent is of renewable vegetable origin. Formulations are given.

Abstract: A method of making coatings, marking products and/or sealing products from a starting material including aggregate, includes the step of adding to a starting material a binder including at least one resin based on polymerized hydroxyacid derivatives as a non bituminous binder, as a non bituminous binder, the resin(s) being selected from: a) organic resins derived from an oil or a fat having a natural origin including monoglycerides and/or diglycerides, esterified with a poly(hydroxy acid), b) organic resins corresponding to lactic polyacid and polyol esters and/or mono- or polyhydroxylated polyacid esters, c) organic resins based on lactic polyacid or lactic polyacid derivatives such as corresponding esters thereof.

Abstract: A method for preparing a fluxing oil, having an iodine number ranging from 50 to 200, based on fatty substances of natural origin having been chemically functionalized by oxidation, includes the steps of: i) providing a fatty substance or a mixture of fatty substances of natural origin, ii) subjecting the fatty substance or the mixture of fatty substances of natural origin to at least one transesterification or esterification reaction by at least one alkanol or mono-alcohol, iii) subjecting the compound or mixture of compounds obtained at step ii) to at least one chemical functionalization reaction by oxidation introducing at least one functional group selected from carboxylic acid, epoxy, peroxide, aldehyde, ether, ester, alcohol and ketone groups, and iv) collecting the fluxing oil.

Abstract: The present invention relates to an organic resin derived from a naturally occurring oil or fat comprising monoglycerides and/or diglycerides, esterified with a poly(hydroxy acid) having the following formula: wherein R1 is a saturated or unsaturated, aliphatic hydrocarbon chain comprising from 6 to 32 carbon atoms; R2 is a hydrogen atom, a —COR4 group, where R4 is defined according to the same definition as R1 or a poly(hydroxy acid) esterified group; the poly(hydroxy acid) group corresponding to [hydroxy acid]n—CO—X—OH is a linear or a branched chain, obtained by condensating hydroxy acid monomers that are the same or different; depending on the nature of the hydroxy acid, X=—CH2, —CHR, where R is an alkyl group having from 1 to 5 carbon atoms and comprising from 0 to 5 hydroxyl function(s); and n is the number of hydroxy acid units that are the same or different and does range from 3 to 2000.
