Asphalt concrete pavements have a short life cycle, failing mainly due to temperature changes, traffic loading and ageing. Modified asphalt mixtures provide the technology to produce a bituminous binder with improved viscoelastic properties, which remain in balance over a wider temperature range and loading conditions. In this research, 60/70 penetration grade asphalt binder was modified by add...

Bio-oil is a dark brown, mobile liquid derived from the thermo-chemical processing of bio-mass. Bio-oils generally contain water and lignin. Lignins are highly-available, well-studied carbohydrate derivative known for their antioxidant properties. For asphalt pavements, oxidation can cause deterioration, a longterm aging process, and eventually result in cracking. Therefore, bio-oil could poten...

Abstract The performance of the asphalt mixture is affected by characteristics and gradation aggregate. Polymer-modified has been widely used to overcome road pavement damage such as cracking, spalling, yielding, due deformation grooves, curling, or rutting. used, both from plastomers elastomeric types. Elvaloy modification resulted conventional mixing process 60/70 with additives Dupont that a...

Asphalt is a visco-elastic material having properties of elastic solid at low temperature and viscous liquid at high temperature. Properties of asphalt binder depend upon temperature, rate of loading and aging conditions. Although asphalt binder is only 4-5 % of asphalt concrete mix by weight but it plays a vital role in defining the pavement performance. That is, pavement response is heavily d...

With the strengthened regulation on the mandatory use of recycled aggregate, development of construction materials using recycled aggregate has recently increased. This study aimed to secure the performance of asphalt concrete mixture by developing recycled-modified asphalt using recycled basalt aggregate from the Jeju area. The strength of the basalt aggregate from the Jeju area used in this s...
