Description

Kit of components for the manufacture of pavement construction elements and method of manufacturing such elements

The present invention relates to a kit of components for the manufacture of pavement elements, such as imitation elements of paving or pavement imitating, in particular, natural stone and a method of manufacturing such elements pavement development.

It is common to have on the roadway elements of development such as slabs or paving stones that can serve as decorative elements or marking on the ground. The marking on the ground is used, for example, for the delimitation of roundabouts, axial strips separating lanes and pedestrian crosswalks, for marking parking spaces in car parks and for the laying of the median central. In decorative elements, slabs and pavers can be placed at the entrance of buildings or at the edge of gutters.

As shown in FIG. 1, and conventionally, the installation of the development elements on the roadway 10 first requires pouring a concrete slab 13 inside the foundation layer 11 of the roadway 10. A layer of mortar laying 14 is then placed on the concrete slab 13. pavers, such as blocks 2 and 3, next to each other on the laying mortar 14 and inside a mix 12, once said laying mortar 14 has taken. A joint mortar 15 is then cast between each block.

However, in the more or less long term, we often see deterioration of these elements of development, especially on the so-called heavy traffic roads, that is to say on which heavy vehicles circulate. These deteriorations are mainly due to infiltration of water between the pavements, repeated passages of vehicles, cycles of freezing and thawing, foundations that are not sufficiently stable. In addition, the laying mortars are often poorly proportioned and the joint mortars are friable and brittle.

In order to limit these problems, one solution is to use elements imitating the paving or paving. It is then possible to get rid of the use of real pavers as well as laying mortars and joint mortars.

Unfortunately, these imitation paving or paving elements remain sensitive to heavy traffic.

The object of the present invention is therefore to propose a kit of components for the manufacture of pavement layout elements that can be used for the manufacture of imitation elements of natural pavers or slabs, particularly cobblestones or stone slabs, in pavement layout, on a support such as concrete or asphalt, such landscaping elements not having the disadvantages mentioned above.

For this purpose, a kit of components for the manufacture of pavement layout elements according to the invention is characterized in that it comprises:

a powder component comprising a mixture of: cement,

- silica flour,

quartz particles having a particle size of between 0.2 and 1.6 mm,

quartz particles having a particle size of between 0.8 and 1.8 mm,

synthetic polypropylene fibers, a liquid component comprising synthetic polymer resin.

The components of the kit according to the invention, once mixed, allow the manufacture of a mortar of very good quality and very good performance that can be used for the manufacture of pavement elements. In particular, the mortar obtained after mixing the components has the advantage of being easy to apply because very malleable, to be applicable in thin layer and to adhere to a certain way to its support. Polypropylene synthetic fibers ensure the internal cohesion of the mortar once cured. Quartz particles help to delay the wear of pavement elements.

This surface aggregate component is an optional component included in the composition of the pavement layout elements. For example, silicon carbide particles are used to cause reverberation of light on the elements. Their very high coefficient of hardness also makes it possible to significantly reduce the wear over time of the pavement management elements and to avoid the phenomenon of surface slippage. The quartz particles distributed on the surface of the elements of arrangement make it possible to give them a granite aspect.

The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, said description being given in relation to the attached drawings, among which:

Fig. 1 represents in section a pavement arranged in a conventional manner with paving stones,

Table I illustrates the composition of a kit according to one embodiment of the invention and FIG. 2 shows in section a pavement fitted with development elements according to the invention.

A kit of components according to the invention for the manufacture of pavement elements, such as imitation paving or paving elements comprises a powder component A, a liquid component B and, in this method of embodiment, a component of surface aggregates C, whose compositions are reported in Table I, according to: Table I

A kit comprising 28 kg of component A, 5 L of component B and 20 kg of component C can be used for the production of pavement elements over an area of 5 to 6 m2.

The powder component A, the composition of which is given in Table I, can be bagged.

The liquid component B is a polymeric synthetic resin preferably packaged in a can.

For 28 kg of powder component A, 5 liters of liquid component B is required, ie 0.178 L of component B / kg of component A. The kit according to the invention may further comprise a component of aggregates C. This component is intended to be distributed on the surface of the landscaping elements. It allows to provoke a reverberation of the light on the elements of arrangement. It also helps to slow the wear of the elements manufactured. Component C is packaged in a bag of 20 kg, for example.

The kit is used in the method of manufacturing pavement elements as described below.

The first step of the process consists of a cleaning of the support, for example the coating of the roadway. In the next step, a powdered component, such as the powder component A, the composition of which is given in Table I, is mixed with a liquid component, such as the liquid component B, the composition of which is given in FIG. Table I. The liquid component B is gently poured onto the powder component A until a homogenous mortar composition is obtained. This mixing step can be performed using a mixer used at low rotational speed.

In the next step, a matrix delimiting at least one space of specific shape, in this example, the shape of a block, is placed on the support of the roadway. A single matrix allows the manufacture of several pavers. Each matrix thus has a parallelepipedal shape and has walls of a height, for example, of 2 mm, delimiting a void space.

Advantageously, the walls of the dies may be non-parallel to each other and the empty space then takes the form of an inverted trapezium. This will facilitate the removal of the matrix, as explained in the following. A thin layer of the mortar obtained during the mixing step is spread on the matrix and then penetrates inside the empty spaces. The affixed layer may be slightly greater than the height of the walls of the matrices.

At the surface of the mortar, a surface aggregate component, such as component C, the composition of which is given in Table I, can be sprinkled so as to completely cover the layer spread in the previous step.

In a variant of the invention, the component C of surface aggregates is not sprinkled so as to create an effect of concrete pavers.

The mortar is then pressed against the die, without excessive pressure, using a roller, such as a paint roller. Once the layer of mortar has been spread and the surface aggregate component sprinkled, the matrix can be gently removed.

Another clamping step can then be performed using a roller such as a painter's roll. This step is necessary if you want the pavers to have rounded corners.

Fig. 2 illustrates a pavement comprising paving stones manufactured by a method according to the invention, such as the method described above. The roadway 10 is composed of a foundation 1 1 covered with a layer of a mix 12. The landscaping elements such as the pavement 2 are arranged on the asphalt 12. Unlike the conventional method of placing pavers on the roadway, as illustrated in FIG. 1, the method according to the invention does not require pouring of concrete slab in the foundation 11, nor is it necessary to use a laying mortar and a joint mortar .

The method according to the invention thus makes it possible to manufacture pavement layout elements in a simple and effective manner.
