Definitions
- the invention relates to an improved anti-lift system of cracks inserted between the structure layer and the wearing course of a roadway. It relates still to a method for the realization of such a system.
- Road or airport roads are generally formed of several layers, namely a upper layer, called wearing course, based on a material of the surface coated type or even of the concrete type bituminous and one or more lower layers forming the structural layer of the pavement, based on materials treated with hydraulic binders such as cements, dairy blast furnace, pozzolan, fly ash, binders bituminous.
- the various mechanical and thermal stresses of a nature static, for example plug withdrawal and thermal withdrawal materials, or of a dynamic nature, namely constraints related to traffic, to which roadways are subject cause the structure layer to crack, the generated cracks transmitting more or less quickly to the wearing course and then appear on the surface of the latter.
- the presence of cracks on the surface of the pavement allows water to enter the body of said pavement, which causes rapid degradation and important of the latter.
- a more efficient solution consists of interposing, between the structural layer and the wearing course, an interface in non-woven geotextile impregnated with a bituminous binder consisting of a bitumen modified, for example, by a copolymer of styrene and a conjugated diene such as butadiene.
- a pavement covering with a geotextile sheet bonded, using a layer of bituminous adhesive, to the bituminous concrete base layer of a pavement, by example old road surface, said ply being covered with a porous wearing course at bituminous mix base.
- a layer can be arranged on the base layer in bituminous concrete to eliminate surface irregularities of said layer before laying the geotextile sheet.
- the anti-crack recovery system according to the invention which is sandwiched between the structural layer and the wearing course of a pavement, is of the type comprising a layer of a geotextile impregnated with a first bituminous binder and a layer of aggregates coated with a second bituminous binder, which is attached to the layer of geotextile impregnated with the first bituminous binder, and it characterized in that the second bituminous binder associated with aggregates, to form the asphalt layer, are used in an amount between 3% and 20% of the weight of aggregates.
- the system anti-crack recovery is arranged so between the structural layer and the wearing course of the pavement that the geotextile layer impregnated with the first bituminous binder rests on the structural layer of the pavement, while the layer of aggregates coated with second bituminous binder is coated with the layer of rolling.
- the system anti-crack recovery is arranged so between the structural layer and the wearing course of the pavement as the layer of aggregates coated with the second binder bituminous rests on the structure layer of the roadway, while the geotextile layer impregnated with the first bituminous binder is coated with the wearing course.
- the layer of aggregates coated with the second binder bituminous can advantageously be a layer of sand coated with said binder.

- the surface mass of said textile web is preferably between 100 and 300 g / m 2 .
- the first bituminous binder which permeates the geotextile to form the impregnated geotextile layer of the anti-crack rise system, is used advantageously in an amount between 200 g and 1500 g and preferably between 300 g and 1000 g per square meter of geotextile sheet.
- the second bituminous binder associated with aggregates, to form the layer of coated aggregates of the anti-lift system of cracks, is more particularly used in quantity included between 4 and 12% of the weight of the aggregates.
- the aggregate component can be chosen from the various sands that are used on construction sites and whose 6 mm sieve pass is greater than 80% and preferably equal to 100%.
- the aggregate component selected from sands which are used on road construction sites and whose passer-by 6 mm sieve is greater than 80%, is coated with the second bituminous binder, used in aqueous emulsion, after have been previously contacted with a solution surfactant and possibly with a quantity of cement less than 3% of the weight of the sand forming the component aggregate.
- the component aggregate chosen from the gravel that is used on road works and including the passer by a 20 mm sieve is greater than 90%, is hot-coated with the second binder bituminous so as to provide, after compaction, a vacuum content in the mix between 15% and 35% and preferably between 20% and 30%.
