Research on a Laboratory Technique for Tire-Pavement Noise Assessment of Asphalt Mixes

Abstract

Communication noise is classified as one of the pollutions for the current environment. Experimental techniques to measure tire-pavement noise generation from asphalt pavements in the laboratory have been limited. A series of experiments were conducted on six different asphalt mixtures to determine if Purdue University’s Tire-Pavement Test Apparatus (TPTA) could be used to overcome these limitations. The procedure produced samples with low tire-pavement noise; however, the air void contents of the samples were higher than designed. Despite these difficulties, the sample preparation technique and the TPTA testing protocol were shown to offer an effective approach for quick laboratory assessment of tire-pavement noise characteristics of hot mix asphalt pavements at a substantially reduced cost compared to field testing.

Low-Noise pavement technologies and evaluation techniques: a literature review

“…An 22 interchangeable tire travel along the surface and the noise is measured using OBSI microphone 23 conditions, and the test can take several days to complete the noise measurements alone. While the 24 samples sizes are larger, the top speed is only around 50 km/h(Kowalski et al, 2013).…”

Evaluation of mechanical properties for stone mastic asphalt containing textile waste

“…Additives such as fiber or polymer are used to fix the mastic in the stone framed structure and to prevent these infiltrations [26]. Besides, use of fibers can contribute to the reduction of traffic noise that occurs between wheels and surface of pavements [27,28]. Drainage of bitumen is considered as the portion of the mixture (fine materials and bitumen) that flows down the mixture, separating it from the sample as a whole [29,30].…”
