with expanded clay or with mineral wood fibres The factors that mostly affect the efficiency of acoustic barriers are sound-insulation linked to the masses involved and sound-absorption linked to the porosity and shape of the materials. The noise barrier consists of two layers, one of normal reinforced concrete with a density of 2200-2400 kg/mc, having a supporting function, one of light porous concrete with a density of 900-1100kg/mc. FIP and TECNOACUSTICA offer a noise barrier consisting of a 100mm-thick prefabricated structure of self-stable reinforced concrete and a Greek-fretted facade made of lightweight concrete panels with expanded clay and/or mineral wood fibres for a total thickness of 120mm.
The standard length of panels is 292 cm, which permits a typical centre distance of 3 metres. In terms of height, standard measurements of individual panels are 1.5 metres and 2 metres. Panels are fitted onto metal frames that are dimensioned so as to withstand the stress resulting fro

The 6W64 wall consists of very thin reinforced concrete elements that, by alternating voids and fills** during fitting, create a set of pots to be filled with soil; more than 50% of the front surface consists of exposed soil which is arranged according to its natural sloping angle. The foundation elements rest on a concrete slab or on prefabricated elements; they are fitted by alternating right and left elements** and fixing is ensured by steel bars. The fill-in soil shall be green, rich in humus or in any case so as to ensure taking root of vegetation. The soil filling and compacting (to be accomplished by poleaxe) shall be performed every other layer of the structure, in order to let the soil fill completely the space available. It is preferable to fit an automatic sprinkler system during the mounting phase: the low cost is appropriately offset by the saving of maintenance costs and by the advantages in terms of sound-proof performance and appearance. The 6W64 wall can be placed bo

This type of joint was specifically designed for highway use within structures creating horizontal movements up to 15 mm and vertical movements up to 5 mm. Due to its characteristics, it can be fitted on any type of structure, whether it is made of reinforced concrete, prestressed concrete or steel. It consists of: • a Hypalon gutter, ending at its extremes with a mesh securing it to the slab; • a neoprene ribbed bulb, of suitable section, resting onto its upper wings on the edges of the slab heads, recessed within the gap. The Hypalon gutter ensures watertightness of the deck and drainage of waters outside of the road bed. It is a seamless type of gutter and it covers the entire road bed with the right slope and it is fixed to the slab by means of a mesh with epoxy adhesive and primer.

 The function of the neoprene bulb is to support the overhanging pavement. JOINT TYPE HEIGHT H (mm) WIDTH *X (mm) GAP *Y (mm) Bulbo piccolo 43 45 Max 20 Bulbo medio 77 80 Max 40 Bulbo grande 90

They insulate the surroundings from trams, trains and undergrounds-induced vibrations by means of rubber mats, or dull them by means of tuned mass dampers. FIP INDUSTRIALE has developed a wide range of systems to reduce the effects of vibrations. In the railway, tramline and underground sectors, the use of special rubber mats under the ballast or under the reinforced concrete platforms, permits to isolate the surroundings from travelling trucks-induced vibrations. In other sectors vibrations can be dulled by means of tuned mass dampers or some types of seismic devices. TYPES: Damping mats Tuned mass dampers
