Oxidative aging induces significant stiffening of asphalt binders that leads to a pronounced reduction in the overall durability pavements. The strategic implementation antioxidant additives provides potential solution alleviate this issue. This work presents results from second phase global consortium for antioxidants research aimed at investigating effectiveness increasing binders. Sixteen laboratories around world participated effort and total 28 diverse geographical regions were tested....
InfraRed spectrometry is a powerful technique to characterise bituminous binders. The methodology not fully harmonised and may lead variability. RILEM-272-PIM-TG1, evaluated seven complex bituminous, for which eleven laboratories performed FTIR. While, the spectra showed similar trends, further analysis was needed improve comparison. A specific approach applied on two binders, unmodified polymer modified bitumen, ageing conditioning. Combining Gaussian distribution derivative confirmed good...
The utilization of Reclaimed Asphalt (RA) in the road construction sector induces considerable economic and ecological benefits. blending recycled material with new components is believed to be great importance for mixture’s properties. An extensive knowledge materials crucial optimizing use RA, especially at higher recycling rates. In this paper, applicability Fourier transform infrared (FTIR) microscopy attenuated total reflectance (ATR) mode study bituminous coating RA granulates...
Transparent binder is used to substitute conventional black asphalt and provide light-colored pavements, whereas nano-TiO2 has the potential promote photocatalytic self-cleaning properties. Together, these materials multifunction effects benefits when pavement submitted high solar irradiation. This paper analyzes physicochemical rheological properties of a transparent modified with 0.5%, 3.0%, 6.0%, 10.0% compares it base polymer binders (PMB) without nano-TiO2. Their penetration, softening...
The fatigue performance and healing ability of asphalt pavements are important for mixture design, rehabilitation, maintenance the roads. By analyzing these parameters in an mixture, it is possible to predict crack formation propagation cracks during rest periods. effect mixtures has been observed verified by many researchers different methods exist evaluate this phenomenon. However, current still inadequate fully observe quantify phenomenon mixtures. In study, a digital image correlation...
Rheological characterisation methods are important when it comes to a performance-based selection system for bituminous binders road applications. Standardised exist the determination of bitumen rheological behaviour based on dynamic shear rheometer (DSR) at intermediate and high service temperatures bending beam (BBR) low temperatures. Recently, with 4 mm parallel plates (4-mm DSR), has been proposed by Western Research Institute (WRI), as promising method determine Clear advantages 4-mm...
Incorporating reclaimed asphalt (RA) in surface layer mixtures is still limited due to performance concerns, and it becomes even more challenging when combining aged polymer-modified bitumen (PMB) with virgin PMB. This study aims evaluate, from a binder perspective, the feasibility of incorporating (RPMB) new mixtures. To address this challenge, blends RPMB PMB were investigated at three replacement rates (20%, 40% 60%) without tall oil-based rejuvenator. First, viscoelastic behaviour was...
With the increased use of reclaimed asphalt (RA), ability bituminous materials to resist fatigue cracking may face a decline mainly due aged binder (RAB), especially when RA is used at higher rates and not sufficiently treated. In this study, bulk scale (asphalt) its subscale (mortar) were employed evaluate effect on resistance RAB added, by considering three replacement rates: 0%, 40%, 70% RAB. The testing mixtures was carried out using four-point bending (4PB) setup, while mortars tested...
In Flanders, using Reclaimed Asphalt Pavement (RAP) is allowed in asphalt mixes for base layers. Primary economic and secondary laboratory-measured mechanical properties are given as justification higher amounts specific mixes. However, one should evaluate the performance of these on long-term by environmental impact production until end-of-life. this paper recommendations strategies RA, based current research, discussed a broader perspective such carbon-footprint tool warm-mix Flemish...
Industrial waste causes environmental, economic, and social problems. In Morocco, the Jorf Lasfar Thermal Power Station produces two types of coal ash with enormous quantities: fly (FA) Bottom (BA). FA is recovered in cement while BA stored landfills. To reduce effects disposal landfills, several experimental studies have tested possibility their recovery road construction, especially as a subbase. first phase this study, underwent physicochemical geotechnical characterization. The results...
In 2015, the ROAD_IT project initiated development and demonstration of an integrated coherent IT process control system for Flemish asphalt sector in order to modernize existing paving technologies obtain real-time data monitor pavement behavior. One test tracks is CyPaTs, construction a bicycle path built September 2017, using innovative (www.uantwerpen.be/cypats). Five are described this contribution. An solar collector (PSC) with piping was installed directly asphalt. Cold water during...
Currently, reclaimed asphalt (RA) is considered as one of the most recyclable materials in construction industry developed countries. The purpose this paper to investigate effect RA on manufactured mixtures Flanders and define a correlation between mechanical performance through statistical spectrum. In study analysis was carried out dataset 74 bituminous mixtures, certified (2009–2016). A bivariate used determine influential factors impact mixtures. addition, determination major properties...
Asphalt mixtures are the most common types of pavement material used in world. Characterizing mechanical behavior these complex materials is essential durable, cost-effective, and sustainable design. One important properties asphalt modulus elasticity. This parameter can be determined using different standardized methods, which often expensive, to perform, sensitive experimental setup. Therefore, recently, there has been considerable interest developing new, easier, more comprehensive...
Accurate determination of the mechanical properties asphalt concrete is very important in Road Engineering. The traditional method to calculate these run experiments using a hydraulic/pneumatic actuator and strain gauges apply stress measure strain. However, last decade optical measurement techniques have become popular for calculation on surface specimen detecting cracks surface. In this study, digital image correlation used estimate map an specimen, predict location crack initiation,...
