porous asphalt noise reduction

  • NOISE REDUCTION WITH POROUS ASPHALT

    Although two-layer porous asphalt pavements are more expensive than ordinary dense pavements, comparisons done as part of the project of the cost of porous asphalt, noise barriers and sound insulation shows the asphalt to be economically attractive where there is a need for reduction of the traffic noise.
