Cezary Strąk, Ewelina Kozikowska, Marcin Małek, Marcin Wachowski
TL;DR
This study examines how synthetic sports surfaces degrade under accelerated aging, focusing on surface properties and microstructure changes.
Contribution
A new method combining UV radiation and water spray is introduced to simulate aging more realistically.
Findings
Surface degradation was more severe with the UV + spray aging method.
Slip resistance decreased in dry conditions but improved in wet conditions after aging.
Aged surfaces showed reduced differences between dry and wet performance.
Abstract
This study investigates the effect of accelerated aging on the microstructure and surface properties of synthetic sports surfaces, with the goal of developing a more representative laboratory simulation method. Three common types of polyurethane-based sports surfaces were examined: (1) a dual-layer SBR base with a thin EPDM spray topcoat; (2) a single-layer EPDM surface with a smooth finish; and (3) a dual-layer “sandwich” structure with a rough EPDM upper layer. Samples were tested for slip resistance (PTV), abrasion resistance, and surface morphology using SEM, as well as surface roughness and tensile properties before and after aging. Method combining UV radiation and water spray was introduced and evaluated. Microstructural analysis with roughness measurements revealed surface degradation in all materials, with more extensive damage observed in the UV + spray cycle. Slip resistance…
