“…In the Czech Republic, in autumn 2012, the first test run section using EACC 8 surface was constructed (between exits No. 210 and 216 of the D1 motorway), because EACC shows good skid resistance [63,64] as well as low noise emissions [65,66]. However, based on the experience with transverse tining [67], the officials were not in favour of the application of EACC surfaces because, in their opinion, cement concrete surfaces with good skid resistance are still noisier than asphalt surfaces.…”

In this study, results from long-term monitoring of the tyre/road noises of the exposed aggregate cement concrete (EACC) with the highest grain size of 8 mm and stone mastic asphalt (SMA) surface with the highest grain size of 11 mm performed by close-proximity (CPX) method are presented. There are certain concerns that the EACC surface will have inferior noise properties than SMA. These concerns are based on previous experience with the cement concrete surface with transverse tining texture which is very noisy. The main aim of this article is to demonstrate that these concerns are unfounded. A section of the motorway was chosen for the measuring and the testing speed for all measurements was 80 km·h−1. Provisional results (based on six years of monitoring) show that the noise levels measured on both these surface types are similar over their lifetime and exhibit logarithmic acoustic behaviour.

“…Coarse aggregates larger than 4.75 mm can have a major impact on pavement skid resistance [27,28]; consequently, hemispherical shells with diameters of 7, 9, and 13 mm were used to represent different coarse aggregate grain sizes in three simplified pavements, each comprising a single grain size aggregate. The planar size of this simplified pavement was 200 × 200 mm, and the 7, 9, and 13 mm hemispherical shells were arranged in a matrix such that they numbered 28 × 28, 22 × 22, and 15 × 15, respectively.…”

“…The 3D models of the simplified pavements were drawn using the CATIA V5R20 software, as shown in Figure 8. The pavement mean texture depth (MTD) was used to characterise the differences between the macrotextures of the simplified pavements and is expressed as follows: Coarse aggregates larger than 4.75 mm can have a major impact on pavement skid resistance [27,28]; consequently, hemispherical shells with diameters of 7, 9, and 13 mm were used to represent different coarse aggregate grain sizes in three simplified pavements, each comprising a single grain size aggregate.

This study considered the effect of pavement aggregate grain size on tyre–pavement contact interaction during the late stages of pavement skid resistance. First, hemispherical shells 7, 9, and 13 mm in diameter were used to simulate coarse pavement aggregates. Subsequently, a three-dimensional finite element tyre–pavement contact model developed using ABAQUS was employed to analyse the contact interaction between each simplified pavement type and the tyre under steady–state rolling and braking conditions. Finally, the concept of occlusal depth was proposed and applied to characterise pavement skid resistance. The results showed that under steady–state rolling conditions, the peak contact stress of the simplified pavement increased with the pavement mean texture depth, whereas the contact area decreased. Under steady–state braking conditions, the effect of the contact interaction between the tyre and simplified pavement aggregates was ranked in order of superiority as aggregate grain sizes of 9, 7, and 13 mm, indicating that aggregate grain size did not exhibit any correlation with tyre–pavement contact interaction. Additionally, the squares of linear correlation coefficients between the pavement cumulative occlusal depth and horizontal braking force reached 0.921, 0.941, 0.889, and 0.894 for vehicle speeds of 30, 60, 90, and 120 km/h, respectively, indicating that they could be used to assess pavement skid resistance.

“…The road surface texture is a key factor in determining the skid resistance of pavements; good road surface macro-construction and micro-texture is crucial to improve the skid resistance, and the asphalt mixture gradation type, coarse and fine aggregate lithology, and other factors also affect the skid resistance of pavements [2][3][4][5][6][7]. However, in reality, the road surface texture is inevitably affected by external environmental factors, such as rainfall, snowfall, icing, and other pollutants, and the presence of these adherents affects the friction between vehicle tires and the road surface [8,9].…”

In this work, the long-term skid resistance attenuation law of asphalt mixtures in the presence of aeolian sand was studied. Four types of asphalt mixtures underwent skid resistance abrasion tests using an accelerated loading tester. The pendulum value (BPN) and structure depth (MTD) of these four mixtures were determined under various conditions of sand density and abrasion times. The correlation between the BPN and density and the number of times of abrasion were investigated, respectively, to analyze the skid resistance attenuation law at the microscopic and macroscopic levels. Our results indicate that the skid resistance of the four types of asphalt mixtures initially decreased and subsequently reached a stable state. Sand density primarily influences skid resistance during the initial stage, while the number of abrasions becomes the dominant factor affecting skid resistance in the later stages.
