- ROSANNE is a collaborative project in the 7th EU Framework Program which aims at harmonizing measurement methods for skid resistance, noise emission and rolling resistance of road pavements as a preparation for standardization. The project started in November 2013 and is developing and improving standards in the field of working group CEN/TC 227/WG 5.Regarding the influence of the pavement on the road traffic noise emission, the main objective is to combine the existing measurement methods of SPB (ISO 11819-1) and CPX (ISO/DIS 11819-2) into a stable and reliable harmonized pavement noise emission characterization method. A respective procedure is being developed within the project and its potential use for noise calculation methods like the one proposed by the CNOSSOS-EU project is investigated. The first two years of research focused on analyzing and comparing existing noise measurement methods to specify the noise properties of road surfaces as well as investigating the temperature influence of possible correction measures; respective results will be presented in a separate paper on this issue within this conference. Activities related to the compatibility with the CNOSSOS-EU calculation method and to the experimental validation are still ongoing. The present paper shows the current draft of the procedure developed.

- A poroelastic road surface (PERS) consists of rubber granulates and stone aggregates, bound with an elastic resin, such as polyurethane. It does not contain bitumen. Thanks to its elasticity, porosity and texture, it is capable of yielding an unequalled noise reduction, typically 8 - 12 dB(A) with respect to reference dense asphalt concrete. Although already invented in 1979, some persistent problems, the most important being as durability, prevented the use of it for noise abatement.In 2009 the six year EU funded project PERSUADE started, aiming to develop a highly noise reducing, safe and affordable PERS with an acceptable durability. The approach of the PERSUADE consortium was at the same time holistic (all aspects of PERS were studied) and step-wise. It started with laboratory testing of mixes and adhesion to the sub layer. Then small scale pilot test tracks were constructed on parking lots and consequently full scale test tracks on real roads. An extensive monitoring program extracted as much as possible information from the test tracks.Many other relevant aspects, such as cost-benefit, fire safety, toxicity, sustainability, etc were thoroughly studied. This contribution outlines all the findings of the project and makes clear how one go further with this technology.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- 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 scrapped tires) and an elastic resin (like polyurethane). The work is carried out in the framework of the PoroElastic Road Surface for Avoiding Damage to the Environment (PERSUADE) project and has the financial support of the European Commission (EC).The project duration is 6 years, and in the first 3 years, the main focus was on the development of a mixture with a number of criteria: a high noise reduction, a sufficient raveling resistance, a sufficient binding to the sublayer and an acceptable drainability. The research of the consortium involved the testing of numerous samples with a variety of laboratory tests and led to two promising mix formulas. The consortium has started with the construction of five "full-scale" test tracks in five different countries and these tracks will be monitored. The PERSUADE project includes the study of environmental and economic aspects.
