Definitions

  • the subject of the present invention is a method of building a road bituminous complex with high fatigue and impermeability capital.
  • pavements always behave better when they are highly impermeable, which on the one hand limits the profound alteration of the support soils affected by water ( and which, as a result, lose their lift) and, on the other hand, limit the frostiness of the roads affected by the phenomenon known as thaw barriers.
  • the present invention provides significant improvements in these two fields by proposing a three-layer bituminous complex with high fatigue and impermeability capital.
  • the subject of the invention is therefore a method of constructing a road bituminous complex on a support floor, comprising the production of at least one base or base layer and / or a wearing course, with possible interposition of a bonding layer, characterized in that an enriching layer is applied to the support, before the seat layer, by bonding from the bottom of the seat, comprising at least one layer of aggregates and at least one binder layer dosed at more than 800 g / m2.
  • the seat layer The seat layer .
  • bitumen gravel which consists of gravel, coated with a bitumen harder than that traditionally used and whose softening point Ball and Ring (standard NFT 66-008 of July 1979) is between 52 and 65 ° C, instead of 50 to 56 ° C.
  • this layer is applied over 7 to 25 cm representing more than 80% of the entire thickness of the new pavement.
  • the bitumen dosage of the base layer is higher and between 4.5 and 5.5% by weight, instead of 4 to 4.5% in the traditional bitumen , the rest being made up of sand and gravel, each representing at least 30% by weight of the mixture (generally half / half).
  • the enrichment layer The enrichment layer .
  • this layer The purpose of this layer is to bring up an additional binder, in particular bituminous, inside the first 1 or 2 centimeters of the seat layer.
  • This enrichment takes place during the hot application of the serious bitumen of the base which will melt the binder of the lower layer. serving as a sort of "reservoir” because it contains much more binder than is necessary.
  • This molten binder will percolate the bottom layer from the top, during the compression under pressure of the bottom layer.
  • this remelting of the bitumen from the enrichment layer ensures perfect bonding of the seat to the old pavement and strongly waterproofs it.
  • This enrichment layer consists of a reservoir coating which can be produced in the following manner.
  • bituminous binder either hot melted, or in the form of bitumen emulsion
  • a fine layer of protective gravel with a granularity of 4/6 or 6/10 (mm).
  • a second identical coating is produced by spreading a layer of binder and then a layer of gravel.
  • a coating is thus obtained with a double sealing layer: 2 layers of binder interposed with two layers of gravel.
  • the binder is voluntarily overdosed to produce a layer which would quickly exhibit an abundant "bleeding" of bitumen under traffic if this coating were subjected to direct traffic from vehicles. But it is this bleeding, voluntarily amplified in quantity and amplified in speed of exudation (since the serious bitumen which will overcome it will be applied hot around 150 ° C), which is precisely re-sought according to the invention to serve enrichment of the severe bitumen and provide it with additional fatigue resistance. In addition, this bitumen waterproofing layer (in particular the two-layer variant) is even safer once it has been completely remelted.
  • the total quantity spread must be greater than 800 g / m2, that is to say that the excess of binder in relation to a conventional coating is at least 300 g / m2, and preferably between 1.2 kg / m2 and 3 kg / m2.
  • the surface or wearing course The surface or wearing course .
  • the thickness of the seat layer is greater, its flatness is less good and it is necessary to use a slightly thicker surface layer, this to be more likely to obtain the desired final uniform.
  • a coating of the prior art can be applied over a thickness of 2 to 4 cm, which does not require original composition. If the total thickness of the complex is less than 10 cm, it is also possible, according to a variant, that the seat layer itself also fulfills the function of wearing course, provided that the gravel particle size is less than 14 mm.
  • a wearing course is carried out independently of the seat, it is necessary to interpose a bonding layer, consisting of a bituminous binder and dosed at 250 g / m2 or more, in order to improve the bonding of the wearing course and the waterproofing of the seat.
  • a bonding layer consisting of a bituminous binder and dosed at 250 g / m2 or more, in order to improve the bonding of the wearing course and the waterproofing of the seat.
  • at least 400 g / m2 of binder is used in order to reinforce the overall waterproofing of the complex.
  • the method according to the invention can be used not only for the repair of old pavements, in particular for medium traffic, but also for the construction of new pavements or mixed pavements, in particular on a foundation made of fine materials such as fly ash, sand. polluted and other poor quality materials such as chalk, possibly treated, which was practically impossible until now. It is also applicable to the coating of engineering structures.
  • Example 1 Repair of a very damaged (cracked) pavement.
  • the total thickness of this system is approximately 18 cm.
  • Example 2 Application to a foundation made of fine material such as fly ash, treated sand or silt.
  • Example 3 Application to a chalk foundation treated with cement.
  • Example 2a the nailing operation described in Example 2a is not necessary, although it remains advisable. All the layers of the complex are produced in the same way as in Example 2.
  • Example 4 Application in repairing the coverings of a bridge deck:
  • the old coating is removed and the surfaces are cleaned (dust removal).
  • the enrichment coating is produced as described in Example 1a.
  • This base layer is a 0/14 mix coated with 5.4% bitumen and has an average thickness of 7 cm (4 to 10 cm depending on the location since it is mainly used for reprofiling).
  • the surface layer is then applied as in Example 1c but without spreading the binder layer which already exists.
