Soil problems<\/h2>\n
During the design stage, it was identified that the project was being developed in a terrain made up of fine soils of high plasticity, in which uncontrolled fills of excavated material from the site had been placed.<\/p>\n
These materials presented:<\/p>\n
- \n
- \n
low bearing capacity<\/p>\n<\/li>\n
- \n
high susceptibility to permanent deformation<\/p>\n<\/li>\n
- \n
risk of settlement and premature cracking<\/p>\n<\/li>\n<\/ul>\n
A conventional solution would have involved excessive settlement, rutting, increased thickness of granular material, higher costs and a high risk of early failure.<\/p>\n

Improvement of subgrade and granular layers<\/h2>\n
To mitigate the problem, the surface material was replaced by a layer of granular material, increasing the initial bearing capacity of the soil.<\/p>\n
However, due to the soft condition of the natural soil, the necessary thicknesses were too great. Therefore, it was necessary to complement with a system that would guarantee stability, confinement and structural performance without excessively increasing the volumes of material.<\/p>\n
Here, a high modulus woven geotextile type FORTEX<\/strong>who played key roles:<\/p>\n
- \n
- \n
separation between subgrade and granular material<\/p>\n<\/li>\n
- \n
material reinforcement and confinement<\/p>\n<\/li>\n
- \n
reduction of fines pollution<\/p>\n<\/li>\n
- \n
improvement of the structural capacity of the soil-pavement system<\/p>\n<\/li>\n<\/ul>\n
Thanks to this pavement reinforcement with geosynthetics<\/strong>In this way, a uniform platform was achieved, with greater resistance to deformation and volumetric change conditions.<\/p>\n
Subsequently, the subbase and granular base layers were constructed respecting the thicknesses and specifications of the design.<\/p>\n

Reinforcement of the asphalt layer with geogrids<\/h2>\n
A biaxial geogrid was included in the asphalt wearing course. FORTGRID ASPHALT<\/strong> with the objective of preventing cracking and extending pavement life.<\/p>\n
Among its main benefits:<\/p>\n
- \n
- \n
efficient distribution of efforts<\/p>\n<\/li>\n
- \n
fatigue and reflection crack retardation<\/p>\n<\/li>\n
- \n
reduction of future maintenance<\/p>\n<\/li>\n
- \n
improved structural performance under repeated loading<\/p>\n<\/li>\n<\/ul>\n
