Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0023] FIG. 1 shows a perspective view of a roll of asphaltic membrane of a unique layer of asphaltic bitumen according to the present disclosure.

[0024] FIG. 2 shows a perspective view of a roll of asphaltic membrane of two layers of asphaltic bitumen according to the present disclosure.

DETAILED DESCRIPTION

[0025] The asphaltic mass needs a protection to filter the UV rays so as to avoid its aging and to extend its useful life. This function is performed by the superior coating layer that, in the art, may be a metallic foil, preferably aluminum or copper, or slate, or ground rock introduced within the superior part of the asphaltic mass, or polyester films coated with acrylic paint. When a membrane coated with a polyester sheet, generally of non-woven material, is preferred, what it is seeked is the resistance of the waterproof solution against possible aggressions due to pricking and above all, the aptitude for its trafficability.

[0026] The asphaltic membrane with trafficable colored multi-layer coating to waterproof in the present disclosure, that includes at least three layers of material.

[0027] A first inferior layer 1, called non-stick layer, is formed by a sheet of synthetic polymers that help the membrane to manipulate, to conform its laying and, specially to allow its provision in rolls 2 without the asphaltic layer being stuck.

[0028] An intermediate asphaltic layer 3 is stuck to said inferior layer 1, identified as asphaltic layer comprised of asphaltic bitumen that plays the role of waterproofing.

[0029] The third layer 4 of the asphaltic membrane, the superior one known as coating, is a multi-layer laminated assembly obtained from coating by extrusion with resistant characteristics against UV rays, which, in turn, may be provided in a range of different colors.

[0030] The characteristics of the superior layer, that is of the multi-layer laminated assembly, is that same is comprised of a polyester sheet 5 of high resistance and a sheet 6 of synthetic polymers that contain anti-UV additives and is pigmented with different decorative colors, each other adhered by a mass 7 comprised of mixtures of polymers of Pead and/or Pebd, applied at high temperature (coated by extrusion) thermally conforming said laminated assembly, and turning same in a layer of superior coating of the membrane.

[0031] In a second embodiment, the asphaltic layer 8 is made of two asphaltic layers, each other separated by a reinforcement or central core 9. This reinforcement is comprised of a synthetic polymer, preferably a polyester, a polyetilene, or a polypropylene.

[0032] The above description and drawings are only to be considered illustrative of specific embodiments, which achieve the features and advantages described herein. Modifications and substitutions for specific conditions and materials and otherwise can be made. Accordingly, the inventions are not considered as being limited by the foregoing description and drawings, but are intended to embrace all such alternatives, modifications, substitutes and variances.

[0033] The objectives of the disclosures include any combination or sub-combination of the elements of the different types and/or disclosures described herein. People skilled in the art will recognize that those properties and, consequently the scope of the present inventions, should be construed in the light of the following claims and everything equivalent to them.
