This RILEM round robin study with nine participating laboratories investigated bitumen ageing, its effect on chemical properties and reproducibility. The impact of temperature used for short-term (RTFOT) binder ageing the combined short- long-term (PAV) aged samples was investigated; thereby reduced mixing such as those relevant warm mix asphalt technologies long term examined. Four 70/100 penetration graded bituminous binders from different sources were selected. In addition to standard...
The use of waste plastics in partial asphalt binder replacement and substitute for polymer modification has the potential to contribute sustainability road infrastructure as well preservation natural resources. In this study, two types polyethylene (PE) PE-pellets PE-shreds (a by-product former, currently incinerated after production) were blended with a conventional order analyze their effect on chemo-mechanical thermal behavior. Particular attention was paid characterization PE description...
Crumb rubberized asphalt binder achieves value-added recycling of waste scrap tires, as well enhancement mechanical properties and aging resistance pavements. This paper provides a systematic literature review the evolution sustainability implications crumb based on peer reviewed publications during 1993–2022. The analysis shows that methods, chemical-microstructural characterization, rheological-mechanical properties, environmental benefits are main research directions in studying binder....
Properties of asphalt mixtures after ageing are fundamental parameters in determining long-term performance (e.g. durability) these materials. With increasing popularity reduced temperature mixtures, such as warm-mix asphalt, WMA, the question remains how a reduction short-term affects properties bituminous This paper aims to improve our understanding effect manufacturing on and resulting mechanical binder by studying short- different bitumen samples function temperatures. For this purpose,...
Significant volumes of waste materials such as plastics is generated every year worldwide with a potentially harmful impact on the environment. At same time, demand for asphalt modifiers has seen an increase over consequent higher costs these types additives. Therefore, combining large amounts available binder extender or modifier would improve paving material properties while limiting disposed waste. While several rheological studies have been performed in past, they were restricted to...
As a vital and integral component of transportation infrastructure, pavement has direct tangible impact on socio-economic sustainability. In recent years, an influx groundbreaking state-of-the-art materials, structures, equipment, detection technologies related to road engineering have continually progressively emerged, reshaping the landscape systems. There is pressing growing need for timely summarization current research status clear identification future directions in these advanced...
As the use of warm and cold asphalt mixing technologies provides an opportunity to save energy during production, it is important determine if this lower temperature also has a long-term effect on binder chemical rheological properties performance. In study, link between chemistry rheology bituminous binders with focus short-term aging proposed. This made using index (RAI), crossover (CAI). The RAI calculated difference in integration areas under shear modulus master curves generated from...
This research aims to determine if the observed improvements using polyethylene (PE) waste in asphalt binder translate into better performance at mixture scale laboratory environment while overcoming stability and homogeneity issues experienced level. is accomplished through a round-robin multinational experimental program covering four continents, with active participation of eleven laboratories within RILEM TC 279-WMR. PE modified AC16 mixtures were prepared employing dry process local...
