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 ...

Asphalt binder modification techniques are beneficial for the performance improvement of roads because they can be durable, present less permanent deformation, and provide longer fatigue life. The main agents involved in this process polymers, fillers, fibers, and, more recently, nanomaterials, which have presented technical economic feasibility. nanoparticles were added to base asphalt at a co...

The application of asphalt hot mix recycling is one challenge in sustainable road pavement research. In addition to the vast amount research on performance recycled asphalt–concrete, frictional resistance still limited. effects aged and aggregates skid were investigated this carefully extracted from field-reclaimed pavement, engineering mechanical properties virgin measured. degradation was sim...

This study explores the effects of polyphosphoric acid (PPA) on rheological performance styrene butadiene (SBS) and crumb rubber (CR) modified asphalt binders at high temperatures. Four PPA concentrations were selected: 0.4%, 0.8%, 1.2%, 1.6% by weight virgin asphalt, one SBS binder with 5% was used as a reference binder. Laboratory tests performed to simulate short-term long-term aging. Temper...

The article reviews the option of how to make top pavement asphalt-concrete mixture adhere reliably base, which is underlying cement-concrete coating. bitumen-latex emulsion suggested as a binder for two layers.

A significant problem associated with asphalt concrete mixtures is the lack of durability resulting from an inadequate asphalt cement content. Additional asphalt cement added to increase durability results in flushing, bleeding and a significant loss In stability. Fibers have been used in stone matrix asphalt and open-graded friction course pavements successfully throughout Europe to allow high...
