The Poroelastic Road Surface (PERS)

In September 2009, a consortium of 12 partners started to develop a durable, safe and extremely noise-reducing poroelastic road surface (PERS). PERS is a novel pavement type, containing a substantial amount of rubber (new or recycled, e.g. from...

Project PERSUADE

The paper gives a presentation of the Work Package 2 "Mixture optimization" of the European project PERSUADE; a project which aims at developing poroelastic road surfaces (PERS). The latter are assumed to provide a pavement material that provides...

Concept and design of selected innovations for interurban infrastructure

The NR2C vision 2040 designates four main concepts for the road of the future. The innovations considered in WP2 all deal with solutions for one or more of the above concept needs, and mainly with the green infrastructure by reservation of rare...

Improving the mechanical properties of a low noise section

The goal of this innovation initiated in a later phase of NR2C WP2 activities was to evaluate (and eventually to improve) the functional and the mechanical properties (durability) of low-noise poroelastic layers built on cement concrete blocks....

Beständighet hos asfaltbeläggningar

Brister i asfaltlagers beständighet kan antas orsaka stora kostnader församhället. För att förbättra beständigheten på asfaltbeläggningar harvattenkänsligheten undersökts på bitumenbundet bärlager. Av speciellbetydelse för bärlager är dess förmåga...
