In the current recycling process of reclaimed asphalt pavement (RAP), due to serious damage aggregate gradation and large amount aged still wrapped around surface treated aggregate, low rate poor performance recycled mixture are major problems RAP. view shortcomings RAP technology, it is urgent research new treatment methods design specialized asphalt-stripping equipment solve existing problems...

In this paper, annoyance ratings from traffic noise recorded on cobblestones, dense asphalt, and open asphalt rubber pavements are assessed with regard to car speeds and traffic densities. It was found that cobblestones pavements are the most annoying; also while open asphalt rubber pavement imposes less annoyance than dense asphalt it is not significantly different. Higher car speeds always le...

During the last decades, extensive research has been carried out on using reclaimed asphalt pavement (RAP) material in production of hot recycled mix asphalt. Unfortunately, aged, stiff, and brittle binder RAP typically increases mixture stiffness can therefore cause fatigue low-temperature damages. In scientific literature, there are many studies concerning aging rejuvenation bitumen, but is a...

The utilization of reclaimed asphalt pavement (RAP) contributes significantly to reducing resource waste and protecting the environment. However, due performance rejuvenator, fatigue cracking has always been one important constraint on development pavements. Based studies previously conducted by our group, this paper investigated properties rubber/oil (WRO) rejuvenated common dynamic shear rheo...

This study investigated the effect of distribution aged binder from reclaimed asphalt pavement (RAP) on fracture tolerance recycled mixtures. Two RAP sources (one coarse, one fine), virgin polymer-modified binder, and four contents (0 %, 20 30 40 %) were used to produce a total seven Fracture was assessed in terms energy density (FED) at three levels: interstitial component (IC) (composed effec...
