Definitions
- the present invention relates to a method for producing pavement form layers.
- the first phase of the construction of a pavement corresponds to earthworks, carried out using special machines which consist of stripping certain parts in relief and recovering spoil which is used to fill the holes (embankments). This gives a base surface often called “leveling ground” relatively flat and made of coarse materials.
- This surface in addition to its coarse character, often has the drawback of not having sufficient lift to allow the circulation of the construction machinery necessary for the subsequent construction of the road layers.
- the form layer This responds to a wide variety of purposes: adjustment, frost protection, site traffic, protection of the basement against inclement weather, anti-contamination and homogenization of the bearing capacity of the road, etc.
- the characteristics (choice of materials, thickness) of this form layer depend essentially on the nature of the soil in place or the leveling ground, but also on other parameters such as the traffic that can be expected on the site, the time interval between the implementation of the subgrade and the implementation of the pavement, or the climatic conditions of the period of the year during which the site takes place.
- this form layer can be manufactured from a supply of local materials or brought to the site which may or may not undergo a particular treatment, for example using hydraulic binders; these materials can be constituted by natural aggregates or by industrial by-products or by synthetic materials. It also happens that the form layer is simply constituted by the upper part of the leveling ground previously treated over a given height with various materials such as lime, cement ...
- the object of the present invention is to remedy these drawbacks by proposing a form layer essentially containing the aforementioned type of sand, but having satisfactory characteristics, in particular from the point of view of lift, and which can be manufactured at low cost without causing of particular nuisance for the surrounding network.
- the length of the synthetic fibers used in accordance with the invention can vary from a few millimeters to several tens of centimeters depending on the granularity of the sand. These fibers may, in accordance with the invention, have very varied origins.
- transformed natural polymers viscose, acetate, etc.
- synthetic polymers polymers
- mineral fibers glass, carbon, etc.
- metallic fibers glass, carbon, etc.
- the material corresponding to FIG. 1 intrinsically has an index bearing immediate IPI (measured in accordance with the specifications of the Central Laboratory of Bridges and Roads) equal to 22. If one adds to this material 1 per thousand by weight polyacrylonitrile fibers with a diameter equal to 38 microns, we manage to raise
- This corrective sand can in particular be constituted by a crushing sand rich in fines and in coarse elements of particle size 0/4, the particle size curve of which is shown in FIG. 2.
- PROCTOR the operating mode of which was developed by the Central Laboratory of Bridges and Roads. This test is based on the fact that, when samples of the same soil are compacted identically to different water contents, it is found that the density
- REPLACEMENT SHEET apparent dry soil (dry density) varies and goes through a maximum which is obtained for a well determined water content called optimal water content.
- the purpose of the PROCTOR test is to determine, for a standardized compaction of given intensity, the optimal water content and the maximum dry density.
