In this study, the presence of hazardous organic chemicals in surfaces containing recycled rubber tires is investigated. Direct material analyses using solvent extraction, as well as SPME analysis of the vapour phase above the sample, were carried out. Twenty-one rubber mulch samples were collected from nine different playgrounds. In addition, seven commercial samples of recycled rubber pavers ...

Growing demand for road infrastructures and accompanying environmental footprint calls the replacement of pavement materials with recycled options. The complexities in real-world usability are dependent upon project-specific characteristics affected by budgetary constraints local governmental agencies, material applicability, climatical conditions. This study conducts a comprehensive lifecycle ...
