Noise classification methods for urban road surfaces : user manual: measurement methods
- 2006
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Subproject F of the SILENCE project is concerned with the role of road surfaces in the generation of road traffic noise. The project focuses especially on noise abatement in urban areas, and consequently urban road surfaces and their noise emission properties are the main interest of subproject F. Within the subproject, work package F4 plays the important part of providing tools for other work packages to assess the success of new types of road surfaces or the maintenance of existing pavements. This document is the output of the work in task F4.2 and deals with the measurement methods suitable to assess the noise emission of urban road surfaces.The aim of this document is to- Discuss new and existing methods for determining the influence of road surfaces on road traffic noise emission- Point out the restrictions and special considerations that result from the application in urban surroundings- Provide a guideline for measuring the noise emission characteristics of urban road surfaces to the partners in SILENCE and for future use.

Konferensbidrag (refereegranskat)abstract
- ROSANNE is a collaborative project in the Seventh EU Framework Programme which aims at developing/harmonising measurement methods for skid resistance, noise emission and rolling resistance of road pavements as a preparation for standardization. To achieve this, the project is following the recommendations of key predecessor projects like TYROSAFE, HERMES, SILVIA, SILENCE and MIRIAM as well as considering the ongoing work in CEN and ISO groups.Work package 1 deals with skid resistance and aims at the harmonization of skid resistance measurement following the TYROSAFE Roadmap, by deriving conversion factors for friction indices based on similar groups of devices, namely longitudinal and sideways skid resistance measurement devices. During the first project year a first round robin test was carried out in Nantes, ten different devices participated to the test. The results of this test are collected in report D1.2 "Analysis of data from the first round of tests and initial development of the common scale".Work package 2 is dealing with the pavement influence on road traffic noise emission: the main objective of this work package is to combine the existing measurement methods of SPB (ISO 11819-1) and CPX (ISO/DIS 11819-2) into a stable and reliable harmonised pavement noise emission characterisation method. The project is validating procedure incorporating correction mechanisms for temperature influence and investigating its potential use for noise calculation methods like the one proposed by the CNOSSOS-EU project.Work package 3 is dealing with rolling resistance, where the ROSANNE project is mainly building on the results obtained in the MIRIAM project and is considering standardized trailer measurements of rolling resistance coefficients of road surfaces. After a first report D3.1 "State of the art on rolling resistance measurement devices including draft standard outline" the following main report was produced "Parameters influencing rolling resistance and possible correction procedures".In the frame of work package 4 the project is also exploring the potential for developments in the measurement of surface texture in order to find out parameters that better reflect the physical process of tyre/road interaction and that may improve the understanding of how the texture influences noise emission, skid resistance and rolling resistance. In addition to that this work package is also investigating the performance of reference tyres and pavements which are necessary for the measurement of all three road surface properties. The present paper summarizes the project status after the first 18 project months.

Rolling resistance : basic information and state-of-the-art on measurement methods. Final version
- 2011
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- MIRIAM has established a sub-project (SP), designated SP 1, to deal with measurement methods for rolling resistance and related issues. This subject forms the most fundamental basis for the MIRIAM ambition to consider rolling resistance in pavement management or other types of infrastructure systems. Without robust measurement methods and equipment that can use them there will be no reliable data as input to such systems and the end result will be most uncertain, if useful at all.In order to develop and study measurement methods, there must be a basic understanding of the influencing parameters as well as what energy losses that should be included in the concept of rolling resistance. These issues are, therefore, important parts of the work in SP 1.This report is intended to provide basic knowledge about the part of the tyre and road interaction which relates to rolling resistance; for example, the mechanisms that create rolling resistance, and the influence on rolling resistance of various tyre and road parameters. The intention is also to suggest a definition of rolling resistance for the purposes of this project, as well as to provide some detailed state-of-the-art knowledge about the measurement methods and equipment that are useful for collecting rolling resistance data.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- To manage the road network road managers and operators have to consider existing policies such as the requirement to keep the network in good condition, and to deliver this condition at minimum whole life cost. However, the condition should also meet the expectations of stakeholders. The management process has to optimise the total costs for society, whilst minimizing the effects of given condition levels on safety, reliability, environmental impact, economics and sustainability. This principle and its overall goals are equal for all road managers around Europe. Heroad will investigate the process (the combination of individual components, levels of assessment and the inclusion of a life cycle perspective) to incorporate also new challenges in the asset management. This includes:Look at data collection, assessment and reporting regimesConsidering new challenges (climate change, traffic configuration, new materials, LCC and the focus on road users expectations)Identify and assess the key technical components of these regimes and then determine whether they are best practice or notIdentifying and describe indicators at different assessment levels (for road operators complicated technical parameters are okay, for decision makers and public more understandable indicators that could be built from combination of technical parameters are needed)Then pick out the key good parts and provide advice to the customer on how they could use them.

Overall road asset performance
- 2013
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The HeRoad project has investigated the road asset management situation and what practises exist to collect performance measurements in Europe. This has been done in a view from the operational level using a holistic perspective, in the sense that multiple assets and the cross relation between those are included. HeRoad’s approach by addressing the need for condition performance measurements can be justified with some words from (AASHTO, 2011); “What´s measured gets done; if you do not measure results, you cannot tell success from failure.” This implies that the view of investigation has been from the operational level more than from the strategic level (bottom–up).
