Chapter 19 Noise pollution and its impact on human health and the environment

This chapter deals with (1) the basic theory of sound propagation; (2) an overview of noise pollution problem in view of policy and standards by the World Health Organization, the United States, and the European Union; (3) noise exposure sources from aircraft, road traffic and railways, in-vehicle, work, and construction sites, and occupations, and households; (4) the noise pollution impact on human health and the biological environment; (5) modeling of regional noise-affected habitats in protected and unprotected land areas and the marine environment; (6) noise control measures and sustainability in view of sustainable building design, noise mapping, and control measures such as barriers and berms along roadsides, acoustic building materials, roadway vehicle noise source control, road surface, and pavement materials; and (7) environmental noise pollution management measures and their impact on human health

Photodegradation test of asphalt binder using pressed thin film samples

The photodegradation behavior of a straight asphalt was investigated using a new method "photodegradation test of asphalt binder using pressed thin film samples". Although the photodegradation caused by outdoor exposure is limited to the near surface, the results confirmed that the degree of degradation during 1 to 2 months is more severe than that by the pressure aging vessel (PAV) test, which is designed to simulate the degradation that will occur in the asphalt pavement over 5 to 10 service years.Le comportement à la photodégradation d'un asphalte sans additif a été étudié en utilisant une nouvelle méthode, « essai de photodégradation d'échantillons de minces couches pressées de liant routier ». Bien que la photodégradation engendrée par l'exposition aux éléments soit peu profonde, les résultats ont confirmé que le niveau de dégradation durant 1 à 2 mois est plus élevé que celui indiqué par l’essai de vieillissement PAV (pressure aging vessel) qui est conçu pour simuler la dégradation du revêtement en asphalte durant une période de 5 à 10 ans
