Abstract

The skid resistance of runway is critical for ensuring safety. To address durability assessment for runway material selection, this study presents a comprehensive method that couples indoor accelerated wear testing with full-spectrum texture analysis. Three types of asphalt mixtures with different binders (SBS-modified asphalt, polyurethane-modified asphalt (PU), and epoxy asphalt (EP)) were selected for tests under a ground contact pressure of 1.5 MPa at both high-temperature and normal-temperature conditions. The tests were carried out using a self-developed indoor accelerated wear device. Mean Profile Depth (MPD), Power Spectral Density (PSD), and fractal dimension were adopted as full-spectrum texture features, and the British Pendulum Number (BPN) was used to evaluate skid-resistance durability. Grey relational analysis was further applied to examine the relationship between surface texture and skid performance. The results indicated that SBS-modified asphalt exhibited early plastic deformation exceeding 5 mm under heavy aircraft loads. This thermoplastic behavior accelerated the loss of skid resistance. In contrast, the thermoset properties of epoxy and polyurethane asphalt mixtures ensured superior skid and wear resistance. Additionally, Stone Matrix Asphalt (SMA-13) graded mixtures outperformed Asphalt Concrete (AC-16) in wear resistance, indicating better texture retention capabilities. Fractal dimension showed strong correlation with MPD, proving valuable for characterizing surface texture evolution in asphalt mixtures.
