“…The measurements of the tire/road noise were carried out following the CPX methodology used in previous acoustic characterizations of road surfaces [16,25]. Trailer Tiresonic Mk4-LA 2 IC ( Figure 3) is made up of a semi-anechoic chamber which isolates tire/pavement sound from the external traffic or wind noises, in a frequency range of 300 to 4000 Hz where the traffic noise emission is focused.…”

“…Usually, the incorporation of CR as modifier of the bituminous binder, via the wet process, has reflected an improvement of the acoustic performance of the asphalt roads, obtaining a decreasing of the generated sound levels in relation to the percentage of rubber employed in the binder and/or the maximum aggregate size (macrotexture) used in the mixture [14][15][16][17]. Another procedure to incorporate the CR is via the dry process, partially replacing the mineral aggregates in the grading and mixing prior to the addition of the bituminous binder [11,16,18]. Different designs, such as Rubit™ in Sweden and Plusride™ in the USA, have presented promising results reflecting a good sound behavior [19,20].…”

“…The study has been carried out by the Laboratory of Acoustics Applied to Civil Engineering (LA 2 IC) of the University of Castilla-La Mancha (UCLM) through close proximity (CPX) measurements with the semi-anechoic chamber Tiresonic Mk4-LA 2 IC [16] over the test section during its first year of service in order to evaluate its acoustical properties.…”

“…In the last decades, various technical and scientific studies have reported that the addition of CR and other polymers improves mechanical properties of the road surface, such as permanent deformation, stiffness or reflective and thermal cracking [9][10][11][12][13]. Usually, the incorporation of CR as modifier of the bituminous binder, via the wet process, has reflected an improvement of the acoustic performance of the asphalt roads, obtaining a decreasing of the generated sound levels in relation to the percentage of rubber employed in the binder and/or the maximum aggregate size (macrotexture) used in the mixture [14][15][16][17].

Noise Reduction Properties of an Experimental Bituminous Slurry with Crumb Rubber Incorporated by the Dry Process

Nowadays, cold technology for asphalt pavement in the field of road construction is considered as an alternative solution to conventional procedures from both an economic and environmental point of view. Among these techniques, bituminous slurry surfacing is obtaining an important role due to the properties of the obtained wearing course. The functional performance of this type of surfaces is directly related to its rough texture. Nevertheless, this parameter has a significant influence on the tire/road noise generation. To reduce this undesirable effect on the sound performance, new designs of elastic bituminous slurries have been developed. Within the FENIX project, this work presents the acoustical characterization of an experimental bituminous slurry with crumb rubber from wasted automobile tires incorporated by the dry process. The obtained results show that, under controlled operational parameters, the close proximity sound levels associated to the experimental slurry are considerably lower than those emitted by a conventional slurry wearing course. However, after one year of supporting traffic loads and different weather conditions, the evaluated bituminous slurry, although it conserves the original noise reduction properties in relation to the conventional one, noticeably increases the generated OPEN ACCESSCoatings 2014, 4 603 sound emission. Therefore, it is required to continue improving the design of experimental surfaces in order to enhance its long-term performance.

Abstract-Many researchers are trying to obtain a pervious concrete with better physical and mechanical properties to be used in pavement. To achieve the optimized pervious concrete, different researchers have been using different materials, especially those waste materials which are existing worldwide, specifically in the compactly populated areas. Discarded tires are among them and rubber tire particles are being currently used to be considered as recycled waste materials. In this paper a combination of polymer, silica fume and rubber aggregate from rubber tire particles were used to obtain an optimized pervious concrete. The produced concrete's properties were studied. The results indicate that this pervious concrete with the optimum replacing ratio of silica fume, polymer and rubber aggregate to mineral aggregate has higher flexural and compressive strength. The relative flexural and compressive strength of this pervious concrete has been increased 31% and 18% compared to the mineral aggregate pervious concrete. The most properties of this pervious concrete are enhanced. The impact resistance of this pervious concrete is improved 8% compared to mineral aggregate pervious concrete and the permeability meet the standard of Open-Graded Fraction Course. This pervious concrete significantly reduces the elasticity modulus of usual pervious concrete. The impact resistances improved remarkably
