Temperature Correction and Analysis of Pavement Skid Resistance Performance Based on RIOHTrack Full-Scale Track

Abstract

The pavement skid resistance performance index is one of the most important indexes to ensure driving safety. Based on the test data of RIOHTrack full-scale track, this paper analyzes the decay law of pavement skid resistance performance, including the sideway force coefficient (SFC), British pendulum number (BPN), mean texture depth measured by sand patch method (MTD) and sensor measured texture depth by laser method (SMTD), under different equivalent single axle load times (ESALs). The paper analyzes the influence of different methods and conditions on the different indicators and excavates the internal correlation of different pavement skid resistance performance indexes, aiming to improve the effectiveness and accuracy of pavement skid resistance performance detection. The shortcomings of the temperature correction method of BPN and SFC are verified, which cannot correct the skid resistance performance effectively in different temperatures. Based on the assumption that there is a sensitive range of temperature influence on skid resistance performance, a new temperature correction method of skid resistance performance index is proposed based on the Boltzmann model and equivalent temperature of the asphalt surface layer. It can truly reflect the decay law of skid resistance pavement performance. At the same time, the internal correlation between BPN and MTD indicators is analyzed. It is found that there is a linear growth law between two indexes whose correlation coefficient is 0.999, which provides a reference for the research of pavement skid resistance performance.

Complex network approach for the evaluation of asphalt pavement design and construction: a longitudinal study

“…However, the pairwise comparison in 2017 is not significant. This result is in line with a study that used the Boltzmann fitting curve for temperature variations in the pavement TD, which shows a negative correlation between the TD and temperature of an asphalt surface [40]. In addition, an opposite pattern was revealed in the RD measurement, where a high temperature provides a high RD value.…”

Skid Resistance Performance of Asphalt Mixtures Containing Recycled Pavement Materials under Simulated Weather Conditions

“…In addition, at low temperatures, the BPT slider is stiffer and more elastic due to the slider's viscoelastic nature and thus, more energy is needed (generation of hysteresis) for the slider to capture the profile of the aggregates (i.e., microtexture) [42]. Hence, the gripping action of the BPT slider, which is dependent on the surface microtexture, is amplified when the temperature decreases [42,62].…”

“…Again, at low temperatures, the BPT slider becomes stiffer, so a specimen with an increased air void content, which corresponds practically to a rougher surface (i.e., improved macrotexture), makes it more difficult for the slider to bypass its surface (generation of adhesion). In other words, more energy is dissipated, resulting in higher BPN values [42,62]. Therefore, the difference in the air void content appears to be more critical at lower temperatures.…”

Study on the Attenuation of Long-Term Skid Resistance of Asphalt Mixtures under Aeolian Sand Conditions

“…Under freezing conditions, ice and snow fill the road surface voids and reduce the depth of the structure, hindering the direct contact between the tires and the road surface, and the anti-skid performance is then seriously reduced [7,[18][19][20], resulting in the loss of the original stability of the vehicle braking and an increase in the braking distance, which poses a potential hazard to driving safety. There are other pollutants on the road surface, such as sand, salt, and oil leakage, which will also negatively affect the anti-skid performance of the road [21,22] over a long period of time; as the wheels roll over, these pollutants on the road surface are diffused, leading to compaction, thus blocking the asphalt pavement gaps and reducing the roughness of the road surface, so that the road surface loses its original anti-skid performance, especially in the presence of wind-accumulated sand. In addition, changes in temperature also affect the anti-skid performance of pavements [23,24], and the anti-skid performance in summer is generally lower than that in winter under the conditions of a clean road surface.…”
