Description
13215~
The subject o~ the present lnvention is a method for the manufacture n sity of a road membrane reinforced with continuous threads and a device that may be used for this method.
The invention is aimed, in particular, at the re-pair of cracked roadways and pavements, but is also appli-cable to the construction of new roads and pavements.
The repair of cracked roads or roads which are likely to crack (semi-rigid pavements) is traditionally carried out by depositing a thick layer of road asphalts with a high content of asphalt binder. These coated mate-rials are generally manufactured in plants and applied by means of a finisher.
According to another technique, an applicable mortar composed essentially of sand, asphalt binder and filler is interposed between the cracked layer and the wea-ring course - consisting of a road asphalt or of a coatinq - over a thickness of approximately 1 to 3 cm.
It is also known to use a surface layer or an in-termediate layer consisting of a thick asphalt binder stud-ded with aggregates (see for example FR-A-2,231,815).
According to a more recent technique, a geotexti-le, manufactured previously at the factory, is interposed between the cracked layer and the wearing course, possibly wlth a blnder. However, these materials present numerous problems because it is not easy to unwind in a satisfactory - manner rolls of geotextiles and to lay the widths which it ~is difficult to cover successfully. Moreover, this system ;, , ~ , 2 132150~
is very ill adapted to the geometry of the pavement and of the support folds: form in the curves and the changes in camber, which adversely affect the efficiency of the complex.
- 5 A method has now been found for the construction or the repair of roadq and pavements which i5 effective and which may be used on the desired scale, by means of the creation -in situ- of a road membrane reinforced by the installation on the pavement of a network of interlaced threads intimately bound in an asphalt binder.
The invention therefore aims :
a) to avoid, on cracked pavements, cracks rising up through a wearing course, the latter still remaining a complex of small thickness;
b) to increase the fatigue strength of any road covering with respect to repeated stresses, whilst retai-ning the highest modulus levels (rigidity); and c) to ensure the leakproof characteristics of civil engineering work.
The invention relates to a method for the manu-facture -in situ- of a reinforced road membrane comprising the installation of a layer of binder, possibly the inter-position of a road base or base course and, finally, the installation of a wearing course in the form of a road as-phalt or of a chip seal, characterized in that a continuous thread or set of continuous threads forming the reinforc-ement is projected, as a network,on the layer of binder.
If appropriate, this sheet of threads is covered 3 1321~
with a layer of aggregate or with a prefabricated lattice, with possibly a layer of binder, before the installation of the following layer or layers.
According to an alternative embodiment, the ins-tallation of the layer of binding and the projection of a continuous thread or a qet of continuous threads on the latter if perfQrmed simultaneously.
The binder used for the first layer is either an asphalt, or an asphalt-polymer, which may be fluxed asphalt or an asphalt emul~ion, and it may be applied with the aid of conventional equipment either hot, or cold in the form of an emulsion at the rate of 0.2 to 4 kg/m2, preferably 0.6 to 1.5 kg/m2, of residual binder. The threads projected onto thi~ binder will be incorporated therein upon subse-quent application of the wearing course ~or, possible, of the road base or base course) and will form the reinforce-ment of the latter. The complex thereby obtained will en-sure the continuity of aqphalt between the support la~er and the new covering.
The threads used according to the invention may be natural or qynthetic threads, treated or untreated, parti-cularly made from polyester, polyamide, polypropylene or from cellulose derivatives or, alternatively from glass.
Preference i~ given to polyester or polyamide threads. They may be used on coils or rollers of 1 to 1,000 multistrand ~ingle threads. Their grade may vary within a wide range of from 80 to 5,000 decitex, preferably from 150 to ~00 deci-tex. According to the invention, use will be ma~e of 30 to 4 1321~Q4 400 g/m2 threads, preferably from 40 to 120 g/m2. The threads rapidly projected onto the binder form a leakproof reinforced membrane with the latter in the final road com-plex.
In order to stabilize the threads on the binder and then to be able to drive on the latter in order to pro-duce the wearing course which will cover this reinforced membrane, it is preferable to spread on the surface oE t~le sheet of threads a thin grld of aggreyates. The la~ter will generally be formed of chippings (for example 6/10 mm), spread at the rate of 2 to 10 l/m2, for example approxima-tely 5 l/m , but other particle sizes and measurements may be envisaged. These aggregates do not need to be rolled. A
prefabricated lattice may also be used, in particular a metal lattice or a lattice made of polypropylene. In cer-tain cases, a second layer of binder may be applied.
The wearing course is produced in a conventionalmanner, possibly with prior interposition of a road base or base cour~e according to current technology. The invention applied equally well in the case of a hot-road asphalt as in the case of a chip seal.
The following examples illustrate the invention.
EXAMPLE 1 : Repair of the road which is very cracked due to a lack of ~tructure.
An asphalt-polymer emulsion lnatural latex, such as Neoflex R manufactured by the company SCREG Sud-F.st) is employed, using a spreader, at a rate of 1.2 kg/m2 (i.e.
approximately 0.8 kg/m of residual binder).
13215~
Polyester threads ~4 thread~ 167 decitex of 30 strands e~ch, purchased from the company Rhone-Poulenc) is projected onto the layer of binder at a rate of 50 g/m2 by means of a compressed-air spray gun, so as to obtain a net-work of interlocked threads.
6/10 chippings are then spread at a rate of 5 l/m2.
Finally, the wearing course is produced by em-ploying a traditional road asphalt (a~phalt concrete n / 1 o ), using a finisher, at a rate of 80 kg/m2.
By way of comparison, on the same section, a layerof the same road asphalt as above was spread, at a rate of 120 kg/m2. After the passage of traffic, the cracks in the support began to reappear, unlike the reinforced bed obta;ned above according to the invention.
EXAMPLE 2 : Repair of a cracking road at a town exit;
After having spread an asphalt emulsion at the rate of 1.2 kg/m2 (0.8 kg/m2 of residual a~phalt), a com-pressed-air gun is u sed to project a polye~ter thread of 20330 deci.tex and 60 strands (from the company Rhone-Pou-lenc), from a roller of 80 threads, at a rate of 80 g/m2.
Thi~ is covered with 5 1/m2 of 6/10 chippings, then as asphalt concrete wearing course is produced (Compoflex~
from the company SCREG Sud-Est), spread at a rate of 80 kg / m A~ in Example 1, a pavement is obtained whic~
comprises a reinforced road membrane (binder + threads) and which combines ~reat qualities of solidity and fleXibility.

A further subject of the invention is a device which may be used in the carrying out of the method des-cribed above to perform the projection, as a network, of a thread or set of threads, characterized in that it compri-ses a frame, preferably a movable frame, on which are fixedmeans for storing the thread~, means for guiding the - threads and means for eiecting the threads in the direction of the ground.
The mean~ for storing the threads consist of at least one roller support, preferably slaves to by a speed regulator for the roller.
The mean~ for guiding the threads are used to direct the threads from the roller to the means for ejecting the threads.
The means for ejecting the threads consist, in particular, of ejector tubes which are substantially ver-tical, operating with the aid of an air compre~sor. These tubes may be usefully equipped with protection casings. The ejector tubes are preferably arranged by means of a support on an extendible ramp which makes it possi.ble to sweep a desired width of road.
According to one embodiment, the extendible ramp is formed from a set of rods which are articulated toge-ther, the two rods forming the ends of the ramp interacting with a jack which mames it poqsible to adjust the width of the ramp.
The following description with respect to the appended drawings illustrates an embodiment o~ the ~evice 7 1321~
according to the invention. In these drawings :
- Fig. l is a view in elevation of a device accor-ding to the invention for projecting, as a network, a thread or a set of threads;
- Fig. 2 i9 a plan view of the device shown in Fig. l.
In these drawings, the device comprises a movable frame l on which are fixed means for storing the threads consisting of a support 2 for a roller slaved to a ~peed regulator 3 for the roller ~', means 4 for guiding the threads and meanq for ejecting the threads, making it pos-sible to project them, as a network, on the layer of binder already applied, or at the same time as this.
The means 5 for ejecting the threads consist of a ~et of ejector tubes 6 which are substantially vertical, connected to an air compressor 7 and are equipped with pro-tection casings 8 (Fig. l). These ejector tubes 6 are dis-posed by means of their support 9 (Fig. 1) on an extendible ramp formed from a set of rods 10 which are articulated to-2Q gether, the end rods of the ramp interacting with a jack 1l which makes it possible to adjust the width of the ramp according to the width of road being repaired.
The device according to the invention may be dis-posed on a drawn or self-propelled frame. In the case in which the frame is drawn, this frame may be equipped with an integral binder ramp, thereby avoiding the assembly being driven on the layer of binder.
Of course, in the ca~e in which the frame doe~: no~
13?,1~
comprise an integral ramp, u~e is make of a ramp, for exam-ple, of a spreader drawing this frame.
In the ca~e in which the frame is self-propelled, it comprises an integral binder ramp as well as a binder reservoir.
~y way of example, the production line on board the frame comprises :
a power sou-rce consisting, for example, of a ther-mal engine producing power, permitting the hydraulic power supply of the uncoiling devices, the pneumatic power supply of the ejector.~ and also the electricpower supply needed for the a~sociated control and slaving devices;
means for storing threads having the form of coils or rollers of 15 kg to 2 tons of threads of widths which may vary from 0.15 to 3.7 m and comprising a bundle of branched-strand thread~ coiled in units as multi-threads which can exceed which can exceed 1,000 units. These sto-rage rollers or coils are progres~ively braked during operation a~ a function of their weight;
a system of uncoiling devices permits the uniform unrolling of the thread~ as a function of the desired feed-ing, and a ~erie~ of air ejector~ accepting the thread~ at the exit of the uncoiling devices in order to proiect them onto the pavement.
If appropriate, the ejectors are equipped with deflector~ making it possible to deflect the threads in order to improve their distribution on the pavemerlt.
The subject o~ the present lnvention is a method for the manufacture n sity of a road membrane reinforced with continuous threads and a device that may be used for this method.
