This paper presents an investigation on the low-temperature properties of asphalt mixture determined with indirect tensile (IDT) and semi-circular bending (SCB) experimental methods. First, IDT notched unnotched SCB tests are performed a set ten different mixtures. Then, maximum stress (strength) along crack surface specimens is estimated using commercial finite-element software cohesive zone modelling. Finally, simple linear relations between numerically strength nominal value...
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...
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 irreversible phenomenon, effective ARA must have capability improve flexibility bituminous and their...
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...
In this paper, the effect of combined use re-recycled Reclaimed Asphalt Pavement (RAP) on performance properties Warm Mix (WMA) was experimentally investigated at both binder and mixture scales. First, a virgin 50/70 Pen Grade fresh Gabbro aggregates were used to prepare conventional Hot (HMA) for surface layers as reference mixture. Then, same mix type produce designed with 40% RAP, 160/220 binder, Sasobit first generation (WMA-1) Next, WMA-1 artificially aged simulate design adopted second...
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...
A large amount of solid waste, such as steel slag (SS), is generated annually. At the same time, shortage road construction materials becoming a concern. In this study, to recycle and reuse SS substitute for natural aggregates achieve resource conservation sustainable development roads were conducted. First, electromagnetic performance was explored evaluate its wave-absorbing properties. Next, effect different contents on heating properties, surface temperature, uniformity, ice melting time...
In this paper, the effect of physical hardening and aging temperatures on low temperature rheological properties asphalt binder is experimentally investigated modelled. First, Dynamic Shear Rheometer (DSR) tests are performed from −30°C to 80°C four virgin binders corresponding long-term aged binders, which were previously short-term at three different (123°C, 143°C, 163°C). Master curves generated evaluate impact temperatures, while also addressed through a simple testing procedure. Then,...
In this paper, the combined effect of aging temperatures and cooling medium on rheological properties asphalt binder was experimentally investigated evaluated. Two 70/100 penetration grade binders, which were part core materials used by active RILEM committee CMB-252, selected for purpose. The artificially aged to six different conditions, first with Rolling Thin Film Oven Test (RTFOT) at three (123°C, 143°C, 163°C), then, standard Pressure Aging Vessel (PAV). Next, temperature frequency...
Inter-laboratory experiments were designed to evaluate the impact of plastic waste blended directly in bitumen and assess properties, using conventional advanced bituminous binder testing.The blends targeted 5% 95% bitumen, two types polyethylene (PE) primary (pellets) secondary (shreds) waste.The showed that addition PE does not alter chemistry blending is physical.The DSR results indicate a strong dependency on testing temperature as at low temperatures composite material behave both...
In the present study, effects of adding fibers and Reclaimed Asphalt Pavement (RAP) on low temperature performances open graded asphalt mixtures for surface layer dense surface, binder, base layers were investigated. Two different kinds used: a combination aramid polyolefins utilized preparing fiber reinforced porous mixtures, while polyacrylonitrile employed producing conventional layers. Reference made with virgin materials as benchmark to study fibers' addition. Moreover, composed 30% RAP...
