A Comparative Study on Skid Resistance of Concrete Pavements Differing in Texturing Technique

Abstract

The paper presents a comparison of the skid resistance of concrete pavements textured with different techniques in the process of simulating phenomena occurring in actual road conditions. Tests were carried out on five different texturing methods for concrete pavements: burlap drag (BuD), brush drag (BrD), transverse tining (TT), longitudinal tining (LT) and exposed aggregate concrete (EAC). Changes in the skid resistance were recorded by measurements with a British pendulum tester and a circular texture meter before and during the simulation of the abrasion (1st phase of test) and polishing (2nd phase of test) of specimens using a slab polisher. The results of BPN (British pendulum number) and MPD (mean profile depth) allowed us to determine the influence of microtexture and macrotexture on skid resistance. Analysis of variance showed that the method of texturing concrete pavements has a significant influence on the mean BPN values as well as the MPD parameter at each stage of the test. In order to distinguish homogeneous groups in terms of BPN and MPD levels at the particular stages of the process, the Tukey’s HSD (honest significant difference) post-hoc test was performed. It was found that EAC obtained the most favorable results of all the tested pavement types. Due to the high value of the MPD coefficient after the test and the appropriate values of the friction coefficient, it was confirmed that the EAC pavement will be a durable solution due to the guarantee of skid resistance on high-speed roads during its service life.

Comparison of Exposed Aggregate Cement Concrete Surface and Stone Mastic Asphalt Surface Noise Emissions by Close-Proximity Method

“…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.…”

Research on surface treatment technology for quickly improving the skid resistance of tunnel concrete pavement

“…The anti-skid performance of the road surface is mainly determined by both macro and micro textures [16][17][18]. Therefore, the most effective way to improve the anti-skid performance is to simultaneously improve the macro [19] and micro [20] textures of the original concrete pavement [21]. The re-making anti-skid structures method only enhances the macro texture of the road surface, so the effect of this method on improving the anti-skid durability performance is not significant.…”

Toughness Behavior of SBR Acrylate Copolymer-Modified Pervious Concrete with Single-Sized Aggregates

“…Normal pervious concrete is mainly composed by virtue of large aggregates with little to no fine aggregates [ 2 ]. Many countries have adopted pervious concrete to infiltrate and purify the rainwater, to reduce traffic noise, and to raise the pavement skid resistance [ 3 , 4 ] due to its significant air void ratio and well-textured surface [ 5 ]. However, confined by the defects of easy cracking, pervious concrete is merely applied in traffic roads or parking lots subject to lower traffic load.…”
