UNICAL DRAIN BIKE

UNICAL DRAIN BIKE has been formulated for the construction of bicycle and pedestrian paths, especially in a rural or rural context where the subgrade soil is subject to deformation over time and variability along the route.‎ In these applications, rather than the load to which they are subjected, drainage pavements must resist deformations imposed by the subgrade, which must in any case be correctly designed and executed.‎ Performance references In this concrete, hydraulic parameters such as porosity and permeability are adequate for the application.‎ A minimum of 150 mm has been assumed on ballast with a minimum thickness of 200 mm depending on the type of subgrade.‎ The choice of fine aggregate ensures sufficiently comfortable transit for bicycles, wheelchairs, scooters.‎ The UNICAL DRAIN BIKE formulation is suitable for all types of paving: with a vibratory paver, with rollers, with a straight-edge and mechanical trowel.‎ The maintenance of workability is on average sufficient for all types of product application.‎ The Unical Drainage Concrete DRAIN Although not one of the newest construction technologies, drainage concrete is experiencing renewed interest, especially among administrations, which are increasingly committed to sustainable stormwater management.‎ The high water flow rate, which can drain through the porous matrix of the material, allows rainfall to be captured and percolate into the ground.‎ This results in a number of benefits.‎ The most significant of these are the recharge of the water table, improvements in the quality level of the water returned to the water body, and a reduction in the runoff of rainwater from impermeable surfaces in metropolitan areas into watercourses during increasingly intense rainfall events.‎ The drainage pavement and ballast can act as a useful lamination reservoir to compensate for the considerable difference in permeability between the pavement and the underlying soil.‎ Their porosity therefore allows water from the most intense meteorological events to be stored and then reintegrated.‎ All these hydraulic advantages are obtained against a floor bearing capacity that cannot be found in any other similar solution, such as, for example, draining ballast.‎ However, to achieve these results, it is necessary that the construction details are carefully carried out at the construction site and the laying methods adhere to the design specifications.‎ Advantages of drainage pavements Appropriate design of Unical DRAIN drainage concretes gives them the following characteristics.‎ Permeability: is the volumetric flow rate of water that passes through the surface unit of a draining concrete slab in the unit of time: it is an index of its ability to allow the infiltration of water from intense meteorological events.‎ Load-bearing capacity: this is the capacity of the floor system to bear the loads on it which, in turn, is a function of the substrate, thickness and flexural strength of the draining concrete slab.‎ Porosity: represents the amount of voids within the drainage concrete floor slab: it is an indication of its ability to act as a storage layer.‎ Pollutant removal: drainage pavement systems have a considerable capacity to remove pollutants that rainwater intercepts on the surfaces over which it drains.‎ Mitigation of the urban heat island: drainage concrete improves thermo-hygrometric conditions, decreasing the heat island effect typical of densely populated urban areas.‎ Colouring: drainage concrete can be pigmented throughout the entire thickness of the pavement by colouring the paste that surrounds the aggregates.‎ This feature gives the product a uniform colour.‎ Architectural finish: with a particular workmanship on site, it is possible to obtain a surface in keeping with a rural context given the changing colouring of the aggregates on sight.‎ Photoluminiscent finish: it is possible to achieve an attractive photoluminiscent finish thanks to the use of materials capable of emitting light at night after having absorbed light energy during the day.‎
