“…Moreover, ranking between binders, according to the ageing kinetics, is the same for natural and accelerated ageing. This study should provide a better understanding of the influence of ageing on pavement surface properties like skid resistance (Kane, Zhao, Chailleux, Delarrard, & Do, 2013).…”

Ageing of asphalt binders leads to evolution of pavements mechanical performances, due to changes in their rheological behaviour and in the binder composition. Ageing leads to a hardening of asphalt, mainly due to the oxidation of the asphalt binder itself. Oxidation rate is influenced by several parameters, namely outside temperature, ultraviolet (UV) radiation and intrinsic characteristics of the mixture constituents. In order to assess physical and chemical characteristics of the binders in aged pavements, mixture samples of several centimetres in thickness are usually cored from the field. Binders are extracted from these asphalt samples. This process of extraction is typical but it does not allow differentiating bulk and surface characteristics. Indeed, only the surface binder is exposed to UV rays and weathering. In order to assess the ageing of only the surface layer, to verify, for instance the influence of ageing on adhesion characteristics, it is necessary to extract and recover only the surface asphalt binder. A new test protocol, presented in this paper, has been developed to fulfil this purpose. This protocol consists in sampling only small particles at the surface layer, extracting the binder from the particles and performing Fourier transform infrared spectroscopy (FTIR) tests to assess the ageing of the binder. As the quantity of binder is very small, a specific FTIR test method is used. This method consists in keeping the binder diluted in the solvent and placing the solution in the ray of the spectrometer to perform the measurement. This new method has been compared to a more typical one, which consists in applying the binder on a transparent plate after having extracted the binder from the solvent. Once it has been checked that the two methods provide the same results for three kinds of binders, surface ageing tests have been performed. Two different ageing processes were considered: an ageing on site and an accelerated ageing protocol using a climate chamber named Weatherometer (SUNTERTXXL+). In this chamber, temperature, humidity and rain are controlled. The comparison between the ageing in the laboratory and the field allowed correlating both processes to establish an accelerator factor with respect to the increase in carboxyl group.

“…As the most commonly used materials in the pavement, the common asphalt mixtures' skid resistance development has basically thorough investigated. However, Qian's research on epoxy asphalt mixture shows that with the similar mixture gradation, the skid resistance development trend of epoxy asphalt mixture was the same as the asphalt mixtures but the peak value of epoxy asphalt mixture appeared later and also higher than that of the Kane et al also compared the changes in skid resistance and the carbonyl index, a chemical function linked to asphalt ageing and found that the ageing of the organic phase of the asphalt caused an increase of skid resistance in the first year (Kane, Zhao, Chailleux, Delarrard and Do, 2013). Hadiwardoyo et al investigated the relationship of skid resistance and asphalt penetration index, which shows a fairly strong correlation, the higher the penetration index, the larger skid resistance (Hadiwardoyo, Sinaga and Fikri, 2013).…”

The polyurethane-bound porous mixture (PPM) is a new type of pavement materials, which has shown some potentials of overcoming common asphalt mixtures mechanical failures, but little research has been done on its skid resistance performance. This study conducted a comparative study of the skid resistance development between PPM and asphalt mixtures at their early stage. In this study, three mixtures bonded by polyurethane, 70# virgin bitumen and SBS modified asphalt, respectively, were compared and were named as PPM, BAM and Pendulum Number peak value and stable value of PPM are lower than that of SAM. The order of the Number of Loading Times of Peak (NLTP) of three mixtures is SAM>PPM>BAM. Another good linear relationship is also found between BC and NLTP, and the R 2 of the fitting model is 0.85, which indicates the polishing property of binder is a good factor to predict the occasion that the skid resistance peak value occurs.
