Abstract
A method for producing sound absorbing, vibration-damping and/or heat/cold insulating units (1) of rubber waste from for example tyres. The material is decomposed and mixed with a binding agent and is solidified in a mould. The units can be used as noise protecting screens along roads. Holder means (2) and lifting means (4) can be imbedded in the material before the solidification.
Claims9
A method for producing sound absorbing railway units constructed of rubber waste material, the method comprising the steps of:
- configuring a mold in the shape of a unit to be manufactured, said mold adapted to support a holder that is arranged to extend therein;
- decomposing the rubber waste;
- mixing a bicomponent glue used as a binding agent with said decomposed rubber waste to form a mixture;
- pouring the mixture into said mold;
- solidifying said mixture by cold-setting to form the unit;
- and
- removing said unit from the mold;
- wherein said units are adapted to be placed alongside a railway, said binding agent creating a unit having resilient and sound-absorbing properties.
A railway sound absorbing unit constructed of rubber waste mixed with a binding agent and bonded together, said binding agent having resilient cold-setting properties that creates a unit having resilient and sound-absorbing properties, said unit having at least one holder adapted to connect to at least one foundation positioned alongside a railway.
