To investigate the influence of multiple cycles aging and rejuvenation on rheological, chemical, morphological properties styrene–butadiene–styrene (SBS)-modified asphalt-binders, asphalt-binders were aged using two laboratory simulation methods, namely a rolling thin film oven (RTFO) test for short-term pressure vessel (PAV) long-term aging. The then rejuvenated with three types rejuvenators (...

Wild animal hunters and photographers have long taken advantage of the attraction that catnip holds over members of the cat family, while domestic cat owners purchase dried catnip leaves for use as a rejuvenator and exerciser that will bring old cats to new life. Indeed, when cats have the leaves placed near them, they immediately approach, sniff, and shortly thereafter rub their faces into the...

BACKGROUND Pistacia integerrima (P. integerrina) insect galls are widely used in ayurveda and siddha system of medicine as karkatasringi. The use of leaf galls as a rejuvenator may be attributed to antioxidant property, however there is less scientific evidence. Therefore, the aim of this study was to evaluate the chemical composition and the antioxidant potential of leaf gall extracts (aqueous...

Morinda citrifolia (Indian mulberry or noni) fruit has been long used as a folk medicine for a wide range of health purposes as it is claimed to have analgesic, antiinflammatory, antioxidant, detoxifier, and cell-rejuvenator properties. A recent study has revealed central nervous system suppressant nature of its extract. Hence, the present study has evaluated the anxiolytic, sedative, and hypno...

Medicinal herbs have a rich history of their utilization for variety ailments. India is categorized among those countries which produced vast medicinal plants. also called as “Botanical garden the world”. plants are source discovery new drugs across world. Most available today some herbal content in them. Rubia Cordifolia (Manjishtha) climber herb having small flowers greenish white colour grou...

Reusing reclaimed asphalt pavements (RAPs) provides economic, social, and environmental benefits. To improve the performance of these materials, rejuvenating agents such as waste cooking oil (WCO) have been implemented. The annual amounts RAP WCO available in Área Metropolitana de Bucaramanga (AMB) were calculated to be 32 thousand 22 tons per year, respectively. Subsequently, international sta...

Abstract This study intends to examine the effect of using bio-rejuvenators (BioCS and BitutechRAP) on Reclaimed Asphalt (RA) binder as seen from asphalt stiffness modulus (Sbit) based laboratory testing Dynamic Shear Rheometer (DSR) Frequency Sweep which is compared Sbit resulting analysis Van der Poel nomograph under RTFO (rolling thin film oven) conditions. The comparison was analyzed by loo...

The molecular dynamics (MD) simulation method is proved as an efficient tool to explore the intermolecular interaction between rejuvenators and aged bitumen, but simple “single-molecule” model of rejuvenator would bring inaccuracy outputs due a huge difference with its realistic multi-component chrematistic. This study aims in-depth analyze chemical components four commonly-used Gas chromatogra...
