Safe, eco-friendly poroelastic road surface

The SEPOR project deals with development of an innovative poroelastic road surface characterized by extremely low road traffic noise, water permeability, properties of fire suppression from spills of liquid fuels, good properties in terms of rolling resistance and high skid resistance. World development of poroelastic pavements is stil lat the experimental stage where insufficient durability is one of the most important issue to be solved. Poroelastic pavement consists of 20% (by weight) of rubber granulate coming from scrap tyres. That leads to saving of natural stone aggregate and optimal utilization of used car tyres. That implementation of poroelastic wearing course leads to important traffic noise reduction (up to 12 dB comparing with a typical widely used SMA11 pavement) and makes if difficult, or even eliminate the spread of tire of spilled liquid fuels, making them ideal for use in tunnels, gas stations and terminal areas. The main goals of SEPOR project is to improve its durability by optimization of poroelastic mix composition, improvement of the production proces and increasing the interlayer bonding strenght. The project also aims to optimize skid resistance and noise reduction. Experimental test sections of poroelastic pavements will be constructed within a trafficked road and tested for noise, rolling resistance, skid resistance and fire suppression properties.

  • Poroelastic Road Surface – a Promising Road Traffic Noise Abatement Solution
    Publication

    - Year 2018

    Road surfaces have a direct impact on the generation of noise by rolling tyres, the main and dominant source of noise of moving vehicles, as well as may affect propagation of noise emitted by all noise sources of a vehicle. Thus there is no doubt that pavement should be considered as one of the major potential road traffic noise abatement measure. Low noise pavements of existing types may in new conditions provide up to 8 dB of...

  • Poroelastic Road Surfaces - State of The Art
    Publication

    - Year 2018

    Poroelastic Road Surfaces (PERS) constitute a specific group of pavements containing a great amount of crumbled rubber. In most cases rubber aggregate constitutes about 20% of the mixture (by weight) and a polyurethane resin is used as a binder. As a result, PERS is characterized by a much higher elasticity than asphalt and a high porosity typical for drainage pavements. Due to this, tire/road noise is greatly reduced and on top...

  • TIRE/ROAD NOISE AND TIRE ROLLING RESISTANCE ON PROTOTYPE PERS SURFACE

    Poroelastic road surfaces are characterized by low noise of tires running on them.Road pavements of this type are promising solution to problems related to traffic noise in cities and on rural roads. Some technical problems still have to be solved, in particular regarding durability and skid resistance on wet surface. Ongoing and planned works are to contribute to create a quiet, durable and safe road surface, which will become...
