Investigation of Asphalt Pavement to Improve Environmental Noise and Water Sustainability

Abstract

Controlling environmental noise and reducing excessive noise is necessary to protect human health and provide auditory comfort. People are frequently exposed to traffic noise in their daily life and traffic noise is a considerable problem on the city scale. This study investigates the sound absorption coefficient in asphalt pavements so as to reduce traffic and environmental noise. The important parameters affecting the sound absorption coefficient in asphalt pavement, such as the use of porous asphalt pavements, clogging pores, the mixture content change, the thickness change, and getting wet, were identified. It is stated that the sound absorption coefficient in the asphalt layer can be increased with the use of a porous asphalt layer, and by changing the thickness and mixture content. In addition, with the effects of global warming, water supply problems are observable in cities. In this context, the use of rainwater is of vital importance. Permeability of the asphalt layer and storage of rainwater in the lower layer are recommended. The accumulation of rainwater with the aid of drainage in porous asphalt pavements has been investigated and the use of rainwater within the scope of recycling is explored. Within the scope of the research, the construction of porous asphalt pavements is suggested in a system that can store water, reuse rainwater with a new system proposal, and reduce environmental noise by increasing sound absorption performance. Accordingly, it will be possible to reduce the environmental noise level and to use rainwater within the scope of recycling. According to varying thicknesses, porous asphalt pavements were modeled using the finite element method, and the Von Mises stress and vertical deformation results of different thicknesses were compared.

Mechanical Characteristics of Environmentally Friendly Permeable Pavement: Enhanced Porous Asphalt

“…Furthermore, investigations by Liu et al (2023) and Bozkurt and Karakaş (2022) have focused explicitly on the acoustic benefits of porous asphalt. The unique structure of porous asphalt allows for sound penetration and absorption and has consistently proven effective in mitigating traffic-related noise, particularly in urban settings.…”

Applicable Conditions of Room-and-Pillar Mining Goaf Treatment Methods under a Traffic Load

“…The calculation of the model was performed in two steps. First, prior to analyzing the disturbance depth of the traffic load, the boundary constraint condition of the model was set as the elastic Note: (1) The surface layer is asphalt pavement, and the range of elastic modulus was determined by referring to the existing research [24,25] and specifications [26]. The rest of the parameters were determined according to engineering experience.…”

Adhesion Properties of Recycled High-Viscosity Asphalt–Aggregate Interface under Dynamic Water Erosion

“…Based on the surface-free energy introduction in Section 2.3.2 of this paper, the set of Equation (11) for calculating the surface-free energy of asphalt could be obtained by combining Equation ( 5) and the three known liquid surface energy parameters:…”

“…In China, up to 70 million tons of waste asphalt pavement materials are produced annually, and while the basalt aggregate used for the drainage of asphalt pavement has low reserves and the high-viscosity-modified asphalt cost is high, the use of recycled technology for pavement rehabilitation is particularly necessary [ 9 , 10 , 11 , 12 ]. On the one hand, researchers used the recycling agent to regenerate aged high-viscosity asphalt and evaluate the conventional performance of recycled asphalt.…”
