Abstract
To thoroughly explore the relationship between concrete pavement texture characteristics and tire/pavement noise of grooving concrete pavement, the surface texture, i.e., roughness, macrotexture, and microtexture, was investigated in numerous highway pavements. The On-Board Sound Intensity (OBSI) method was used to test the pavement/tire noise. The statistical correlation between concrete pavement texture characteristics and tire/pavement noise was quantitatively described by two correlation analysis methods for highway concrete pavement: origin of linear regression and the Pearson two-sided test method. The results indicate that the effect of pavement roughness on tire/pavement noise is significant, while the noise level is minor for the flat pavement. The macro texture depth also has a marked impact on the tire/pavement noise. In addition, a large grooving depth of concrete pavement could cause a high tire/pavement noise level; however, there is no clear correlation between side-way force coefficient (SFC) and tire/pavement noise.
Highlights
With the rapid development of the economy, concrete pavement design should meet the basic requirements of vehicular traffic, and improve its surface functions, such as skidding resistance, durability, and low noise
Tire/road noise mainly comes from the air pumping effect and vibration effect, which depend on the surface texture characteristics of grooving concrete pavement [21]
Concrete pavement noises are collected by an on-board sound intensity system (OBSI) and statistical analysis results show that there are different correlations between pavement surface texture characteristics and the noise value
Summary
With the rapid development of the economy, concrete pavement design should meet the basic requirements of vehicular traffic, and improve its surface functions, such as skidding resistance, durability, and low noise. A serious concern in engineering to reduce the noise of concrete pavement, especially in heavily populated areas, highways near the city, and tunnels [1,2]. Noise barriers, green forest, and other ways were often used to reduce the tire/pavement noise level. Some results have shown that concrete pavement surface textural features are closely correlated to the tire/pavement noise. Utilizing a “quiet” concrete pavement texture has a significant advantage in noise reduction on pavements [4,5,6]
