The use of waste materials has been increasingly conceived as a sustainable alternative to conventional in the road construction industry, concerns have arisen from uncontrolled exploitation natural resources recent years. Re-refined acidic sludge (RAS) obtained material—acidic sludge—is an source for bitumen. This study’s primary purpose is evaluate resistance warm mix asphalt (WMA) mixtures c...

Porous asphalt (PA) mixtures are more environmentally friendly but have lower durability than dense-graded mixtures. Additives can be incorporated into PA to enhance their mechanical strength; however, they may compromise the hydraulic characteristics, increase total cost of pavement, and negatively affect environment. In this paper, were produced with 5 different types additives including 4 fi...

The present experimental research investigates the feasibility of partial substitution of styrene-butadiene-styrene (SBS) with ground granulated blast-furnace slag (GGBS) for the modification of bitumen and porous asphalt mixtures. The control asphalt mixture and the seven modified porous asphalt mixtures have been analyzed separately and their performance was compared. Modified bitumen and asp...

Observing the microstructure of bituminous binders with an environmental scanning electron microscope (ESEM) can contribute significantly to reveal underlying rejuvenation mechanism. In this study, three rejuvenators were selected regenerate aged SBS modified at five dosages, and their rheology was evaluated using a dynamic shear rheometer. ESEM employed examine as well, series parameters quant...

Weak bonding between layers of pavement leads to damages on the composite pavement. Bonding plays an important role in the durability and maintenance of composite pavement layers. The present study evaluates the factors effective in bond strength of the interface between concrete and asphalt pavements. The factors considered for this purpose include steel slag percentage in the concrete pavemen...

When temperatures drop to significantly low levels, road pavements are subjected thermally-induced stresses, resulting in the appearance of thermal cracking, among other distresses. In these situations, polymers can be used as asphalt binder modifiers improve certain properties, such elastic recovery, cohesion, and ductility. Polymers also minimize some problems mixtures, fatigue cracking perma...

The aim of the work is to develop a polymer-bitumen insulating composition based on petroleum bitumen and secondary products chemical industry. Investigated physical properties product production polypropylene, adsorbent oil gas industry, powder crushed tires. It has been established, technology their introduction into compositions influence technological physical-mechanical investigated, optim...
