Stone mastic asphalt (SMA) has become widely used in the field of pavement engineering. Using specific additives SMA is necessary due to climate change and load condition variations. Thus, it essential utilise a modern mixture with high capacity survive traffic loads. The current study aims use combination waste polyethene terephthalate (PET) Nano-silica (NS) as newly developed hybrid additive ...

Stone mastic asphalt pavements are preferred worldwide as they more resistant to heavy traffic loads. The stone pavement design involves the use of 70-80% coarse aggregate, 8-12% filler, 5-7% binder, and approximately 0.3-0.5% fibre. gap-graded structure high binder content cause bitumen drain down from aggregates. Marshall test Schellenberg drainage performed in this research on samples prepar...

Stone mastic asphalt (SMA) mix amended with sugarcane bagasse fibers (SBFs) as a stabilizer was investigated experimentally in the present study. The SBF content combination varied (0, 0.15%, 0.30%, 0.45% and 0.60%) to produce different mixtures. prepared mixtures were then assessed for properties, such Marshall stability, tensile strength, draindown, which are crucial performance of flexible/b...

background:  controversy exists as to the potential of asphalt fumes to induce respiratory symptoms and lung functional impairments. objective: to examine the respiratory effects, if any, of occupational inhalation exposure to asphalt fumes. methods:  in this cross-sectional study, 74 asphalt workers and 110 unexposed employees were investigated. the prevalence of respiratory symptoms among sub...
