Comparison of pavement noise properties on selected road sections using different CPX measuring systems: self-powered vehicle and special test trailer
Abstract
The recently published ISO standard intended to measure the noise properties of road surfaces in a standardized method (ISO 11819-2:2017) precisely defines measurement procedure of the influence of road surface on traffic noise. According to it, two types of test vehicles may be utilized: a self-powered vehicle fitted with one or more test tyres and a trailer towed by a separate vehicle with one or more test tyres mounted on the trailer. The microphones are located in the close-proximity of the test tyre in strictly defined positions. Round Robin Test using both types of test vehicles was carried out in Poland. The objective was the comparison of noise properties of selected pavements in terms of noise levels obtained when using different CPX measuring systems and to determine if pavement ranking regarding the noise properties is the same. Twelve road sections of six different wearing course mixes were selected for this purpose. Measurements were performed by two independent teams operating two different CPX measuring systems equipped with different test tyres. The RRT results show significant differences in CPX noise levels ranging from –0.9 to +2.3 dB. The pavement ranking is generally the same with some exceptions for less noisy road surfaces.
