Abstract [en]

Exposure to excessively high noise levels is a relevant health problem in Europe and road traffic noise is the most widespread noise source. When considering cold climate countries, the available scientific literature on noise emission properties of winter tyres is still very limited. In order to contribute into filling this knowledge gap, this paper investigates the acoustical performance of different types of tyres, with focus on winter tyres, on different road surfaces, at different speeds, and with different states of wear. The results indicate that studded winter tyres have, indeed, an increased noise level at frequencies between 315 Hz and 10 kHz, having a significantly different response especially at frequencies higher than 4 kHz. The acoustical response also depends on the tyre type when comparing different road surfaces, as a result of conflicting vibrational and aerodynamic noise generation mechanisms. Additionally, the relationship between labelled and measured values was explored, however, no statistically significant relationship was found between them (and labelling is not applied for studded tyres). A frequency spectrum correction was attempted based on previous measurements on an ISO track, which reduced the difference between measured and labelled values, however, further investigation is still required to properly understand differences between label and road measurements, where the label is determined on a test track with a special, smooth surface.

Abstract [en]

Multichannel Analysis of Surface Waves (MASW) is a seismic exploration method to evaluate shear wave velocity profiles of near-surface materials. MASW was applied at seven locations in or close to the South Iceland Seismic Zone, providing shear wave velocity profiles for the top-most 15–25 m. The profiles were utilized for seismic soil classification according to Eurocode 8. The results indicated that the sites that are characterized by sandy glaciofluvial, littoral or alluvial sediments fall into category C and the sites where the deposits are cemented to some degree belong to category B. Furthermore, the MASW measurements were used to evaluate the liquefaction potential at a site where liquefaction sand boils were observed during an Mw6.3 earthquake occurring in May 2008. The simplified procedure of assessing cyclic stress ratio to normalized shear wave velocity revealed that liquefaction had occurred down to 3–4 m depth, which is consistent with observations on site.

Abstract [en]

An experimentally based prediction model of road abrasion wear due to studded tyres is available in Sweden and has been found to work well. However, it has not been validated since 2007, and since then road surfaces and tyre design have developed, and the question has arisen regarding the model’s current validity. The abrasion wear model is used in the NORTRIP emission model (NOn-exhaust Road Traffic Induced Particle emission modelling), and the effect of a recalibrated abrasion wear model on the emission model is shown. In this paper, the abrasion wear model is compared to full-scale field measurements at several recently constructed roads in Sweden to investigate its validity, while also proposing changes to allow for continued use. It is concluded that the model overestimates the wear and an update is suggested. In addition, the impact on NORTRIP emission predictions is briefly investigated. There were also indications that NORTRIP is affected by the abrasion model overestimating the contribution of pavement wear to the particle emissions.

Abstract [en]

Open-Graded (OG) Unbound Granular Materials (UGMs) are generally used in permeable pavement constructions. In this study, the Permanent Deformation (PD) characteristics of two OG UGMs were investigated by means of Multistage (MS) Repeated- Load Triaxial (RLT) tests. The influence of moisture on the PD behavior was also investigated. Compared to a few standard UGMs, these OG UMGs exhibited slightly lower resistance against PD in relatively dry state. On the other hand, these materials were less sensitive to moisture. Therefore, at higher moisture content, the OG UGMs and the standard UGMs showed identical PD behavior. Furthermore, the accumulation of PD was modelled using a simple model which may be used for prediction of rutting, estimating bearing capacity, and for layer thickness design, using a suitable pavement design software.

Abstract [en]

A new Mechanistic-Empirical (M-E) approach is under development to predict the structural degradation of road structures as a function of time. The aim is that the method will become one of the backbones in a new pavement asset management system. The calculation scheme is based two main steps; i) a response calculation step for the different traffic loads applied taking into account the ambient climate and ii) a performance prediction step where pavement degradation is predicted in time steps and thereafter accumulated over the entire design period of the pavement structure. The paper describes the approach briefly and is thereafter demonstrated by a calculation of the degradation of an arterial road in Southern Sweden and compared with measurements from the Swedish Long Term Pavement Performance (LTPP) database. The arterial road had reached the critical 15 mm rut after 18 years in operation. The analysis shows that the rutting development can be simulated adequately although the calculations show slower rate than the measurements towards the end of the simulated period.

Abstract [en]

A pavement surface having deflections from a plane mostly directed downwards in valleys is said to have a “negative texture”, in contrast to a “positive texture” dominated by peaks. Negative textures are typical of porous asphalt pavements, but another way to achieve this feature is to grind off the peaks of the surface. This paper explores the effects of grinding off texture peaks in the horizontal plane on a number of Swedish asphalt pavements in order to reduce noise and rolling resistance. Noise measurements were made to evaluate the ground-off surfaces versus the original surfaces, and, in most cases, also rolling resistance, texture and friction were also evaluated. It was found that grinding led to a more negative texture, tyre/road noise reductions up to 3 dB and tyre/road rolling resistance reductions up to 15%. It is concluded that horizontal grinding provides a maintenance operation with a significant potential for reduction of noise and rolling resistance, without sacrificing friction, though with limited longevity.

Abstract [en]

One possible solution to reduce noise resulting from tyre-pavement interaction is to use a porous pavement surface. A porous surface will reduce noise by decreasing air pressure gradients in the tyre-pavement contact as well as by decreasing the acoustical impedance of the road surface and reducing the horn effect. While reducing noise, other functional aspects of a pavement such as abrasion wear which impacts on air pollution through generation and suspension of particles, friction and rolling resistance need to be addressed. This paper analyses the acoustical behaviour of a Double Layered Porous Asphalt (DLPA), applied in the city of Linköping, Sweden, as a solution to mitigate noise, compared to a non-porous Stone Mastic Asphalt (SMA) pavement used as reference. The analysis is based on Close Proximity noise measurements, both in absolute value and as frequency spectra, acoustical homogeneity over the surface length and sound absorption measurements. The acoustic analysis is combined with analyses of air quality measurements of PM10 (Particulate Matter with aerodynamic diameter < 10 µm) from two Tapered Element Oscillating Microbalance (TEOM) measurement stations placed near each different pavement section. The initial results indicate that the porous pavement results in a noise reduction of up to 5 dB for light vehicles, and up to 4 dB for heavy vehicles. So far, the DPLA shows approximately 52 % lower PM10 concentrations than the SMA. It should be noted that PM10 is influenced also by meteorological conditions, like humidity, background sources as well as vehicle properties, e.g. use of studded tyres, and that some of the observed decrease can be due to other aspects than porosity e.g. road surface moisture and wind direction. In conclusion, the use of a porous pavement shows promising results from both acoustical and air quality aspects, given the initial, short term results

Abstract [en]

An experimentally based prediction model of rut development due to studded tyres is available in Sweden and which had been found to work well. However, since it has not been validated since 2007, during which traffic as well as road and tyre design have developed, the question has arisen regarding the model’s current validity. Also, since the prediction model is used in the NORTRIP (NOn-exhaust Road Traffic Induced Particle emission) emission model, a natural question is how a change in the wear model will affect the emission model. In this paper, two versions of the abrasion model are compared to measurements at several recently constructed roads in Sweden to investigate the validity, while also proposing changes to allow for continued use. In addition, the impact on NORTRIP is briefly investigated. The paper first describes the abrasion models and their calibration, as well as the test sections for calibration. Both versions of the model, as expected, overestimated the wear and an update was suggested. It was also found that NORTRIP is indicatively affected by overestimating the contribution of pavement wear to the emissions.

Abstract [en]

Multichannel analysis of surface waves (MASW) is a seismic exploration method for determination of near-surface shear wave velocity profiles based on analysis of horizontally travelling Rayleigh waves. This paper aims to propose a methodology and recommendations for combining dispersion data from several multichannel records. The dispersion curves are added up within logarithmically spaced wavelength intervals and the uncertainty of the mean phase velocity estimates is evaluated by using classical statistics and the bootstrap. The results indicate that combining multiple dispersion curves, which have been gathered by receiver spreads of different lengths (but with the same midpoint), can increase the investigation depth of the survey, improve its resolution at shallow depth and overall improve the reliability of the results as compared to the use of a single record. Moreover, the uncertainty of the combined mean dispersion curve can be determined and further used to present the shear wave velocity profile with upper and lower boundaries.

Abstract [en]

In Europe, the regulation on weights and dimensions of trucks are complex : European rules are given by EC Directive 96/53/EC as modified by Directive (EU) 2015/719 [1]. These rules apply for international traffic, but countries can decide to add specific national rules. Moreover, these rules are often different from one country to another, due to policy choices and local history. More specifically, the impact of trucks on infrastructure has not always been the primary fact for defining these rules. But in other countries or other research domains, performance based standards (PBS) are used to determine what is allowed, in terms of performance. For example, vehicles may be allowed in terms of their induced damage on bridges (Bridge Formula, see [2]) or dynamic behavior (PBS as in Australia for example). In another context, materials and structures are now often defined in calls for tender in terms of performance (durability, resistance for example). In this context, the work package (WP) C (Fit for purpose road vehicles to influence modal choice) of CEDR project FALCON (Freight And Logistics in a multimodal CONtext) aims at developing Performance Based Standards [3]. For that, the first step is to create a state-of-the art of the European situation concerning vehicle policy and infrastructure. This paper summarizes this work: the first section gives insight on the European vehicle policy. The second section presents the infrastructure catalogue developed within the FALCON project. Finally, these infrastructure elements are characterized in terms of design criteria in Section 3.
