Due to the high price of crude oil, and consequently asphalt binder, the application of Reclaimed Asphalt Pavement (RAP) in pavement technology is widely considered. The present paper is the result of a laboratory research which was carried out to investigate the effects of adding a rejuvenating agent to Hot Mix Asphalt (HMA) with RAP. To this end, test samples comprised of Aged Asphalt Binder ...

Withania somnifera (Ashawagandha) is very revered herb of the Indian Ayurvedic system of medicine as a Rasayana (tonic). It is used for various kinds of disease processes and specially as a nervine tonic. Considering these facts many scientific studies were carried out and its adaptogenic / anti-stress activities were studied in detail. In experimental models it increases the stamina of rats du...

Conductive alginate capsules encapsulating a bitumen rejuvenator (HealRoad capsules) has demonstrated good healing abilities in pure and mortar mixes. HealRoad can efficiently heal damage via induction heating. They also release the encapsulated rejuvenator, thereby rejuvenating aged bitumen. These findings indicate that heating systems combined could represent possible asphalt pavement mainten...

Road degradation is an increasing problem for assets managers. Roads deteriorate mainly due to the combination of different factors, such as temperature, climate and traffic loads. This causes asphalt age and, consequently, bituminous mixtures become more fragile microcracks begin appear. To eliminate these effects, most widely used performed actions are based on renovation pavement achieve sur...

Despite asphalt self-healing with encapsulated rejuvenators having been intensively researched over the last decade, there is still uncertainty about performance advantages granted by this technology. As a way of adding to existing set research methodologies, study aimed test feasibility visual method investigate working mechanism in bituminous mixture. For purpose, clear mixtures were produced...

Abstract At the end of their service life, asphalt pavements exhibit distresses such as cracking and ravelling due to aged bituminous binder. The recycling process reclaimed should compensate for deteriorated binder properties. main objective this study is compare two common strategies: use a softer rejuvenator. Three percentages, 0%, 40% 70% were evaluated. All blends prepared with similar pen...

Natural resources are declining due to rising infrastructure, renovation, demolition, and recycling of existing structures that necessitate sustainable development. It urges the researchers modify aged asphalt binder in enhance performance life asphaltic pavements. The aim this research study is reutilize recycled materials through rejuvenation. This utilizes Cereclor rejuvenate collected from ...
