Complex environmental factors can significantly influence the micro-properties of porous asphalt (PA) mixture. Therefore, effects short-term and long-term thermal aging moisture immersion on micromechanics properties, micro-morphology, chemical element distributions interfacial transition zone (ITZ) PA mixture were studied to reveal mechanisms by which degradation impact performance means nanoi...

The aggregate in an asphalt mixture is coated with mastic consisting of bitumen (dilute phase) and filler (particulates phase). interaction packing plays important role the properties mastics. micromechanics models from composite rheology can be used to predict stiffening effect a suspension. In this research, fillers was investigated based on mastic. frequency sweep tests dynamic shear rheomet...

Viscoelastic characterisation of asphalt mixtures is an important component for modelling and performance prediction flexible pavements. In this study, using spherical indentation testing measuring the viscoelastic properties explored. Indentation may provide interesting alternative to existing experimental techniques, as it capable characterising small material volumes. Thus, become a useful t...

Asphalt resources in Buton Island, Southeast Sulawesi Province are the only natural asphalt deposits Indonesia. In addition to Indonesia, found Trinidad Islands, Albania and Iraq which used for road coatings, building roofs, mastic flooring, paving mixes paint mixtures. This study analyzes levels of Nitrogen, Phosphorus Kaliam at three mining locations, namely: heaps from processing, unprocesse...

SMA is a gap graded mix composed of high concentration coarse aggregate that held together in thick asphalt film by matrix mineral filler and stabilizers. Since natural aggregates have become expensive, hence Reclaimed Asphalt Pavement (RAP) can be reused pavement construction to reduce the environmental hazardous due disposal problems. RAP contains used aggregates, it highly prone fatigue, the...

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...

The cracking resistance of asphalt mixture is a non-negligible issue. However, the evolution law, motivated by two factors (thermos-oxidative aging degree and test temperature), not yet well understood. aim this investigation to gain more insight into effect thermos-oxidative temperature on mixture. Asphalt (AC-13) stone mastic (SMA-13) were selected exposed different thermo-oxidative degrees (...
