Special Issue Information

Dear Colleagues,

The use of low-noise surfaces is a popular and cost effective way to coat road surfaces aiming at reducing traffic noise and consequently its pernicious effect on people. Porous asphalt and thin layers are traditionally used to reduce noise, because of their high porosity and optimized macrotexture. A few attempts to introduce alternative materials and new techniques have been made, challenging current practices. Also, substantial reductions of tyre–road noise levels are soon expected due to the ongoing research on a new generation of low-noise surfaces—the poroelastic surfaces. Research work on durability, acoustic ageing and acoustic classification of the road surfaces is in constant demand. Impacts with social repercussions, such as safety and annoyance, are also being analysed. The goal of this Special Issue is to present the most promising materials (including cement concrete), techniques and methods under development, to address these research needs and to identify new ones. Further, to promote the use of low-noise surfaces by giving a better insight of the cost/benefit when selecting such a noise mitigating measure and, at the same time, the impact on society.

The interdisciplinary nature of the work calls for cooperation in many fields to provide high performance low-noise surfaces.

Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Coatings is an international peer-reviewed Open Access quarterly journal published by MDPI.

Durability of Low-noise Pavements Depends on More than Technology Alone
Wim van Keulen
Low-noise pavements have proven that they can be effective and efficient in reducing annoyance from traffic noise. Not only they reduce noise levels but, probably more important, there subjective impression is considered to be very positive. On the other hand, the durability of low-noise pavements is still a major problem which limits their application significantly. From practice it has been shown that technological research alone is not sufficient to prolong the durability. This paper will present a number of aspects from acoustics, psychology, policy and legal contracts that will facilitate the quest for more durability.

In almost all urban contexts and in many extra-urban conurbations, where road traffic is the main noise pollution source, the use of barriers is not allowed. In these cases, low-noise road surfaces are the most used mitigation action together to traffic density reduction. Selecting the optimal surface is just the first problem that the public administration has to face. In the second place, it has to consider the issue of assessing the efficacy of the mitigation action. The purpose of the LEOPOLDO project was to improve the knowledge in the design and the characterization of low-noise road surfaces, producing guidelines helpful to the public administrations. Six experimental road surfaces have been tested. Moreover, some measurement methods have been implemented aiming to select those that are suitable for a correct assessment of the pavement performance laid as mitigation planning. In this paper, the experience gained in the LEOPOLDO project will be described, focusing on both measurement methods adopted to assess a low-noise road surface performance and criteria by which the experimental results have to be evaluated, presenting a comparison of the results obtained and its monitoring in the time.
