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...

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...

This study quantifies the potential environmental benefits associated with incorporation of industrial by-products and recycled materials combined warm mix asphalt (WMA) additives in wearing course mixtures for pavement construction. An electric arc furnace (EAF) steel slag-based three incorporating slag fractionated reclaimed (RA) varying contents (i.e. 25, 40, 50%) were analyzed comparatively...

In this work, an aged asphalt was mixed with a new modified based on styrene–butadiene–styrene (SBS) in different proportions, and the warm mixing agent added to simulate fusion behaviour recycled fertilizer (reclaimed pavement, RAP) content. Low field nuclear magnetic resonance (LF-NMR), atomic force microscopy (AFM), Fourier transform infrared spectroscopy (FTIR) were used as analytical techn...

Abstract This recommendation is based on the results of an inter-laboratory study organised by RILEM technical committee TC 264-RAP "Asphalt Pavement Recycling"—Task Group 3 (TG3) focusing Asphalt Binder for Recycled Mixture. The TG3 aimed to evaluate effect a specific family materials known as asphalt recycling agent (ARA) aged binder under different configurations. Even though ageing irrevers...

The more reclaimed asphalt pavement (RAP) is used in production, the properties of depend on characteristics RAP. Crushing and sieving RAP into different fractions are most means processing that can allow ensuring consistency desired produced mixture. Currently, however, there no method to compare methods. Here we propose three indexes evaluate crushing screening – Chunk index, Breakdown Filler...
