Bitumen draining in stone mastic asphalt mixtures has become a potential problem. Due to the storage and laying temperatures as well difficulties providing necessary compaction, of mix cannot be lowered prevent or reduce drainage. In asphalts, generally cellulose mineral-based fibers are preferred down bitumen. Conventional commonly used increase pavement costs because they expensive. The aim t...

The experimental investigation of the effects filler-bitumen interaction on stiffening and shearing characteristics asphalt mastic is presented in this paper. role filler particles terms particle dispersion, sedimentation rate, dissipation energy, their response as a function viscosities under different concentrations was analysed. Structural geometrical morphological tests were also carried ou...

When temperatures drop to significantly low levels, road pavements are subjected thermally-induced stresses, resulting in the appearance of thermal cracking, among other distresses. In these situations, polymers can be used as asphalt binder modifiers improve certain properties, such elastic recovery, cohesion, and ductility. Polymers also minimize some problems mixtures, fatigue cracking perma...

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...

Pistacia lentiscus L. is a dioecious shrub or small tree with high drought resistance, native in the entire Mediterranean basin. The variety ‘Chia’ (mastic tree) cultivated for production of mastic gum (a resin produced after wounding trunks and thick branches) Island Chios (Greece), but it also has significant ornamental value. In present study, ten male female genotypes P. var. Chia from natu...
