this study was conducted in order to evaluate the effects of long term ageing on toughness andresilient modulus of asphalt concrete mixtures containing electric arc and basic oxygen furnacesteel slags. after initial evaluation of the properties of steel slags using x-ray diffraction andscanning electric microscope, eleven sets of laboratory mixtures were prepared. each set wastreated replacing ...

this paper is a state-of-the-art in sulphur-asphalt (sa) design technology based on a comprehensive analysis of current practice and technical literature, in order to investigate the possible use of sa pavements in iran. in this paper, the major aspects(material, technology, properties, production, placement, quality assurance, design, and field varification) of sa pavements are considered. fer...

Standard asphalt mixtures for road infrastructures consist of natural aggregate and bitumen. A number of research efforts have successfully investigated the possibility of replacing the conventional aggregate skeleton with industrial by-products such as slag originating from steel production process. However, little is known on the effect of steel slag on the mixtures functional performance and...

In order to study the evolution law of mechanical properties asphalt pavement mixture in cold regions under long-term load, rotary accelerated loading equipment was used carry out a total 500,000 tests on full-scale pavement, and dynamic modulus test before after wheel load carried respectively. The master curve ratio (dynamic value / load) at -20ºC were established predict response low tempera...
