CLAIMS

1. Composition of cement-polymer composite mixture for road infrastructure, based on Portland cement, aggregates, additives and water, characterized in that it consists of Portland Cement 14.5...16.5%, 0.5...3.5% polymer mixture, 0.2...0.25% fly ash, 1...1.15% carbon black coarse, 1...1.15% a coloring agent and 70...80% mineral aggregates consisting of 30...32% sand granulation pit up to 4mm, 11.32...13.32% granite grit of 4...8mm, 33...35% granite grit of 8...16 mm, up to 25% ceramic fibers, textile recycled fibers and / or textile fibers, the percentages being voJumetric.

2. Composition of cement-polymer composite mixture, according to claim 1 , characterized in that for a mountain road of dark color, the composition consists of Portland cement 14...16.5%, 0.5...3% mixture of polymers, 0,2...0.25% fly ash, 1...1.15% carbon black coarse, 70...80% mineral aggregates, up to 25% ceramic fibers, textile recycled fibers and / or textile fibers, as volumetric percentages.

3. Composition of cement-polymer composite mixture, according to claim 1 , characterized in that for a plain road, of light color, the composition consists of Portland cement 14...16.5%, 0.5...3% mixture of polymers, 1...1.15% zinc oxide, 75...80% mineral aggregates, up to 25% ceramic fibers, textile recycled fibers and/or textile fibers, as volumetric percentages.

4. Composition according to claim 1 , characterized in that the polymer mixture is in the form of emulsion and consists of a 1...3% precursor 1 consisting of sodium formate and polyethylene terephthalate in a ratio of 1 :1 , mixed with 0.5...1.5% polyvinyl alcohol, 0.2...0.5% precursor 2 consisting of acrylic copolymer and polyvinyl acetate in a ratio of 1 :1 , 0.05...0.2% precursor 3, consisting of carboxy methyl cellulose, and acrylic copolymer in a ratio of 3:1 , 80...96% precursor 4 consisting of river water.

5. Composition according to claim 1 , characterized in that the sand used with up to 4 mm grain is derived from granite aggregates with a hardness over 6% Los Angeles scale, and aggregates with dimensions of 4...8mm, 8...16 mm from granite compressive strength of 185MPa, elasticity of 34,000MPa tensile strength after freeze-thaw cycle of 22MPa.

6. Process for obtaining a composition of cement-polymer composite mixture, characterized in that for a dark road, they are stirred for 1-5 minutes at a temperature of -4°C...+60oC, preferably 10...+15°C, 15.25% Portland cement with 70% mineral aggregates, 1 % carbon black or another dark coloring agent, plus 0.2% fly ash, a mixture of ceramic fibers or textiles, then added the mixture of polymers previously done separately by mixing and stirring for 15min, and defined in claim 4, continued mixing for another 10...15 minutes.

7. Process for obtaining a composition of cement-polymer composite mixture, according to claim 6, characterized in that for a light road, suitable to the thermal conditions caused by global warming, they are mixed for 1-5 minutes at a temperature of -4°C...+60°C, preferably 10...15°C, 15.25% Portland cement with 70%mineral aggregates, 1% zinc oxide or other pale coloring agent, is added 0.2 % fly ash, tnen is added the polymer emulsion containing the mixture previously done

separately by mixing and stirring for 15 min, and defined in claim 4, ceramics or textile fibers, mixing continued for another 10...15 minutes.

8. Process of application of a composition of cement-polymer composite mixture for road infrastructure, characterized in that on a preexisting layer of 20...40cm of granite mixed with 10% fly ash, which is compacted with a roller compactor of 8-16 tons vibrating and wetting, on which is mounted the casing on the paved road sides (for a road with one lane) or mounted on the shaft road casings (for two lanes of traffic), apply a continuous cement-polymer mixture as defined in claim 1 , with the thickness of 10 to 11cm, using a distributor for concrete, vibration occurs in the depth of the mixture, the surface is vibrating with a vibrant mixture beam to define the running surface, leave it to rest up to 24 hours for drying and after drying, apply 7 hours for smoothing the final layer of polymer, through spraying, when it reach a thickness of 10...11cm layer of running, while still leaving the material to relax a time of 7... 24 hours to accept traffic on paved road.

9. Use of the composition of the cement-polymer composite mixture for construction of road infrastructure, highways, roads and infrastructure, highways, secondary roads, county roads, road pavements, platforms and parking spaces, parking strip, wrapping bands, verges, road forestry roads or agricultural operations, bicycle paths, sidewalks, curbs and gutters, walkways, building, coastal zone stabilization and envelopment, consolidation, stabilization and envelopment dams, decorative paving, pools, water tanks, roofs, gutters and ditches for water reception channels rainwater drain or sewage, pit access, etc..
