Definitions
- the invention relates to a pavement resistant to rutting as well as a method of making such pavement.
- a pavement generally includes a layer of foundation, a base layer, a tie layer and a wearing course. All of these layers are made up of materials treated with either hydraulic binders or hydrocarbons. Materials and binders are determined in depending on the type of traffic the pavement must support or, in other words, depending on the type of wear and deformation to which the roadway will be subject when use. One of these phenomena to which the pavement is thus exposed, is that of rut formation.
- Ruts generally defined as traces or deep marks left by the wheels of a vehicle on a path, are caused by the load of vehicles circulating on the pavement and by the heating thereof.
- Pavement temperature essentially results from the temperature of the soil on which the pavement rests and its heating by sunstroke.
- a roadway intended to support the circulation of heavy vehicles undergoes greater stresses in areas such as for example an approach area of a motorway toll where the roadway must support braking vehicles or storing trucks in queues waiting time, only in the traffic areas of Highway.
- Pavement rutting is dangerous because it channels rainwater and makes the road slippery. This is all no longer true for heavy goods vehicles at the time of the stage of braking when approaching areas such as toll booths.
- different techniques have been tried. So one technique is to mix the bituminous binder with a mixed load of mineral aggregates and flakes of material waste plastic (FR-2,742,174).
- Another technique consists of the use of a road surface composition comprising a hydrocarbon concrete and acrylonitrile fibers, preferably kidney-shaped (FR-2,647,822).
- the object of the invention is to propose a floor resistant to rutting and which is constructed so as to improve its resistance to rut formation.
- This pavement must be able to be produced as well in new construction only under repair.
- the object of the invention is achieved by a roadway resistant to rutting comprising at least one layer of base and a wearing course as well as at least one intermediate layer allowing heat dissipation by ventilation thanks to a high vacuum content.
- the vacuum content indicates the ratio between the volume of void of the middle layer and the entire volume of this last and can be expressed in percent.
- Insert a layer of insulation between the layer of base and the wearing course allows first to associate bituminous products with suitable formulations, for each of the layers constituting the roadway, specific constraints exerted during the use of the pavement and which have a good resistance to rutting. In same time it allows by isolating the lower layers of the pavement of the upper layers, avoid a significant rise in their temperature both by a reduction of the heat transmitted and by ventilation of the intermediate layer, resulting in an evacuation of heat thanks to the high vacuum content.
- the wearing course is usually applied directly or through a layer bonding, on a base layer formed with dense asphalt.
- This dense asphalt layer does not does not fully transmit heat from the layer of rolling towards the bottom layer, but brings a drop of the temperature of the order of 1 ° C per centimeter layer thickness.
- the layer intermediary according to the invention makes it possible to lower this temperature of almost 2 ° C per centimeter of thickness
- the insulating effect of the intermediate layer is obtained by a high vacuum content of the bituminous concrete used for the realization of this layer.
- the vacuum content or the percentage of vacuum, bituminous concrete depends on both the discontinuity of the granularity of the selected gravel and of their shape, as will be described in more detail more far.
- the temperature of the pavement rarely and slightly exceeds the temperature of 60 ° C.
- the base layer provides, according to its thickness, thermal protection of the order of 10 ° C.
- the hard bitumens used for the formulation of the base layer having a softening temperature above 50 ° C, the base layer, which is the most sensitive to rutting is protected by the middle layer.
- the wearing course is made in one thickness of the order of only 2 to 3 cm. So in admitting a rutting of the order of 10%, the ruts which will form during pavement use, have a height not exceeding 2 to 3 mm.
- the height of a rut is defined as the difference of level between the top of two bumps and the level of the trough caused by the passage of vehicle wheels. The height currently tolerated ruts is 5 mm.
- the invention therefore consists not only in using products which, technically, cannot or hardly guide but also to assemble them so that each protect others and that this protection is combined and increased by heat removal.
- the object of the invention is also achieved by a process for producing a pavement resistant to rutting. This process involves laying a layer of base and laying of a wearing course, as well as laying an intermediate layer of a material with a vacuum content high.
- the method of realization also includes laying a layer of attachment to the intermediate layer before laying the wearing course.
- Roadways resistant to rutting and intended for support heavy vehicle traffic such as example the carriageways of a highway, include a foundation layer 1 laid on the support soil and a layer base 2 laid on the foundation layer. These two layers have the function of distributing the vertical loads heavy vehicles and must withstand the fatigue caused by repeated efforts resulting from vehicle traffic.
- the pavement also includes an intermediate layer 3 and a wearing course 4 laid successively one after the other on the layer of base 2.
- the pavement shown in Figure 2 includes a bonding layer 5 applied to the intermediate layer 3 before laying the wearing course 4.
- Base layer 2 is made up of asphalt bituminous produced with gravel having a grading of 0/14 or 0/20 and a hard bitumen of type 10/20 .
- the complex modulus of these coated materials is 14,000 MPa, measured according to standard NF P 98-260.2.
- these bituminous mixes are classified as high modulus asphalt and show rigidity particular ensuring both a good distribution of loads from heavy vehicles and good rutting resistance.
- NF P 98-140 concerns hydrocarbon coated materials and more particularly the layers of high modulus asphalt.
- the value minimum required according to this standard for the complex module is 14,000 MPa at 15 ° C and 10 Hertz.
- Intermediate layer 3 is made with gravel with a grain size 6/10, sand and a modified bitumen.
- the volume proportion of sand compared to gravel is 10%.
- the vacuum content of these mixes is evaluated in the laboratory using a press Gyratory shear according to standard NF P 98-252.
- NF P 98-252 defines a test characterizing the evolution of the void percentage of a mixture hydrocarbon subjected to isothermal compaction. This compaction is obtained by the combination of a shear gyratory and a resulting axial force applied by a mechanical head.
- the wearing course 4 is produced with gravel with a grain size of 6/10, which ensures the surface roughness required on the braking zone of heavy vehicles for example from an approach area of a toll booth.
- the bonding layer 5 optionally applied is made of a cold-cast mix.
