Definitions
- the present invention relates to a hot-melt binder for asphalt product, this binder being based on natural bitumen or bitumen from the petroleum industry, of the type comprising, in addition to this basic product, a first additive consisting of a hydrocarbon wax, the melting point of which, measured according to standards ASTM D3945 and D3418, is greater than 85 ° C.
- phaltic product in the present description, is meant a hot-pourable mixture of bituminous type hot-melt binder with an inorganic filler.
- a well-known asphalt product to which the invention can be applied is poured asphalt, which is a hot vacuum-free mixture generally based on bitumen and mineral fillers which may be asphalt powder. This mixture is hot pourable and hardens by simple cooling to provide various types of coatings.
- the invention also applies to bituminous concretes, produced by coating of aggregates with the binder.
- the mineral fillers used comprise fines, namely particles of dimensions less than 0.08 mm, possibly aggregates, namely sand, that is to say particles of dimensions between 0.08 and 2 mm, and possibly gravel, that is to say particles larger than 2 mm.
- a bituminous type hot-melt binder for asphalt products can be natural bitumen or bitumen from the petroleum industry.
- the binder can also contain various additives such as polymers.
- the preparation of an asphalt product such as mastic asphalt comprises mixing the binder and fillers at a temperature known as "manufacturing", then pouring this mixture at an operating temperature, and finally cooling the mixture sank.
- the manufacturing temperature is between 200 ° C and 270 ° C depending on the compositions and is all the higher when a hard asphalt is sought after cooling.
- This high temperature has the disadvantage of degrading the binders and causing the production of fumes which contain volatile organic compounds.
- known binders of the aforementioned type (FR-A-2 721 936) contain a hydrocarbon wax whose melting point is above 85 ° C.
- hydrocarbon wax saturated polymeric hydrocarbons of low molecular weight, of characteristic appearance, solid at room temperature, with a fairly clear melting point and of low viscosity. Their appearance is translucent to opaque but never glassy. These polymers thus differ in their properties from commonly used polymers and elastomers, which have a fairly wide softening zone and gradually goes from the solid state to the liquid state when the temperature rises. Furthermore, these hydrocarbon waxes are insoluble in bitumen at room temperature.
- low molecular weight is meant a molecular weight less than about 6000 g / mol, and generally between 500 and 6000 g / mol.
- Such waxes make it possible to significantly reduce the viscosity of the product during its use.
- the temperature for manufacturing asphalt with a binder of the aforementioned type is reduced from 30 to 40 ° C compared to traditional asphalts.
- hydrocarbon waxes are soluble in bitumen at the manufacturing temperature, they nevertheless precipitate during cooling and form a network of fibers so as to "arm" the cast coating.
- the asphalt produced on the basis of a binder of the aforementioned type has improved mechanical properties, in particular in terms of resistance to static charges and resistance to fluffing under elevated temperature.
- binders of the aforementioned type are no longer entirely satisfactory, and in particular, given the environmental constraints, changes in regulations will require a significant reduction in smoke emissions during the preparation or implementation of coatings. containing hydrocarbon binders such as mastic asphalt or bituminous concrete.
- the mass content of hydrocarbon wax in the binder is less than 15% of the total mass of the binder. If this content is increased, the manufacturing temperature of the asphalt decreases to a certain extent, but this decrease in temperature is accompanied by a significant degradation of the mechanical properties of the mastic asphalt after cooling.
- the object of the invention is therefore to provide a binder making it possible to prepare asphaltic products, in particular poured asphalts or bituminous concretes, at a lower temperature, while preserving the mechanical properties of the products obtained.
- the subject of the invention is a binder of the aforementioned type, characterized in that it also comprises a second additive consisting of a fatty acid ester wax, this wax being of synthetic, vegetable origin, or fossil vegetable and having a melting point, measured according to said standards, less than 85 ° C.
- “Fatty acid esters” are esters of organic carboxylic monoacids with long carbon chains, in particular with linear carbon chains.
- the molecules of these ester waxes comprise a carbon number greater than 20 and preferably greater than 40.
- These products can be of vegetable origin, for example derived from palm oil, from fossil vegetable origin, such as for example fossil waxes of lignite or of synthetic origin.
- These fatty acid ester waxes have a clear melting point and have a low viscosity as soon as they reach their melting point.
- fatty acid esters are esters of montanic acid (or esters of octasonoic acid), acid of formula C 28 H 56 - O 2 or esters of lignoceric acid (or ester of tetracosanoic acid) , acid of formula C 24 H 4 s - O 2 .
- the penetrability of the basic product is in the 35/50 range
- the hydrocarbon wax is substantially insoluble at ambient temperatures in the base bitumen of the binder
- the acid number of said fatty acid ester is between 10 and 70 mg KOH / g, in particular between 20 and 40 mg KOH / g; and - said acid number is substantially 28 mg KOH / g.
- the binder according to the invention may comprise one or more of the characteristics which are the subject of claims 2 to 15, taken in isolation or in any technically possible combination.
- the subject of the invention is also a process for the preparation of a hot-pourable asphalt product which hardens by simple cooling, comprising the following steps:
- step (a) mixing a binder as defined above with fillers, in particular mineral fillers such as fines, sand and possibly gravel, (b) pouring the mixture from step (a), and
- steps (c) the poured mixture is allowed to cool, characterized in that steps (a) and (b) are carried out at a temperature between 150 and 170 ° C.
- the subject of the invention is also a hot-pourable asphaltic product which hardens by simple cooling, characterized in that it contains a binder as defined above and fillers, in particular mineral fillers, such as fines, sand and possibly gravel.
- This asphalt product has good resistance under static and / or dynamic load. It also exhibits good resistance to cooling as well as to heating.
- the asphalt product contains recycled asphalt recycled during manufacture.
- Asphalt recycled in manufacturing means pieces of surfacing of used asphalt which can be crushed. This recovery asphalt can be remelted hot with a hot-melt binder according to the invention, possibly adding other fillers. The molten asphalt mass can itself be hot cast and hardened by cooling like a conventional asphalt product.
- the asphalt products according to the invention can be used for the production of waterproofing coatings for buildings, waterproofing coatings for civil engineering works, road surfaces and urban developments. In particular, they can be used to stabilize rockfill especially on banks, or fill trenches of small width, especially for burial of small section wiring.
- Cables with a diameter of less than 20 mm are called "small section cabling", in particular low power energy transport cables or fiber optic cables.
- the hot melt is poured between stones and is called in this case "riprap putty".
- the banks are sealed.
- the products according to the invention apply particularly to this use because of their ability to flow hot in a controlled manner and their good resistance to creep on a sloping surface.
- the hot-melt binder according to the invention also finds a use for coating waste during a process of inerting said waste;
- This waste which can be fine and very fine particles, must be stored and can be coated beforehand with inerting agents to isolate it by treatment of the external environment and avoid in particular the phenomenon of leaching by rainwater. .
- the finer the charge the greater the consumption of the coating agent.
- the binder of the invention allows, thanks to its good hot flowability, to perfectly coat these fine particles while using a moderate amount of coating agent and by providing, after cooling, a rigid and full inerting mass. .
- bituminous concrete characterized in that it contains a binder as defined above and mineral aggregates comprising sand and gravel.
- bituminous concretes according to the invention can be used as pavement for roads and roads.
