Fatigue sensitivity of four different asphalt binders and three mixes was evaluated in the study. Binders were subjected to Linear Amplitude Sweep (LAS) test at temperatures 10, 20, 30°C. Four-point beam bending (4PBBT) conducted on a temperature 20°C for strain amplitudes varying from 200 1000 microstrains. Tests like retained Marshall Stability indirect tensile strength (ITS) also carried out judge mix performance. Experimental studies demonstrated that elastomeric modified binder gave...
The main objective of the study was to characterize fatigue and rutting behavior polymer-modified asphalt binders, by determining effect temperature stress/strain levels on results multiple stress creep recovery (MSCR) linear amplitude sweep (LAS) test. modifiers included styrene butadiene (SBS) ethylene vinyl acetate (EVA). These effects were quantified means nonrecoverable compliance (Jnr) percent (R) values in MSCR, power law model Parameters A α LAS also compared with conventional VG 10...
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...
Various rutting susceptibility parameters for unmodified and modified bitumen were studied at three different temperatures of 40, 50, 60°C. Wheel rut testing was also conducted on bituminous mixes The test used to evaluate the performance correlated with mix results, best suited method identified. It found that ranking binders respect remained unaltered irrespective any method. Statistically, multiple stress creep recovery (MSCR) correlate more accurately wheel results as compared other...
The present study aims at studying ageing characteristics of conventional bitumen, polymer modified bitumen (PMB) and warm mix asphalt (WMA) by using FTIR. Results obtained FTIR spectrum were quantified calculating different indices finally based on these index the binders for short- long-term calculated. showed increased amount complex high molecular weight components binders. PMB was found to have greater resistance than In case WMA, results be inconclusive, requiring further investigation.
Abstract Latest research is focused on predicting the fatigue behavior of asphalt mixtures through cost-effective and simple test methods mastic level (asphalt binder + mineral fines). There are numerous for binders using dynamic shear rheometer (DSR). However, up to now, results different tests DSR have not been directly compared. Therefore, four mixes were prepared, each was tested with two most popular [linear amplitude sweep (LAS) time (TS) test] then compared other. The TS performed as...
AbstractStudying the effects of material variability on performance warm mix asphalt (WMA) is important to understand benefits reduced production temperatures. This study compares five different WMA mixtures prepared with two varying base binders and aggregate sources. The rutting, fatigue, moisture sensitivity were evaluated using cyclic compression test, indirect tensile cracking modified Lottman respectively. Additionally, a theoretical analysis was used compare energy consumption during...
Increase in traffic, new axle configurations and high temperature, demands the use of modified binders for resisting stresses induced. The primary goal modifier is to increase stiffness at temperature while maintaining its flexibility lower temperatures. It tends effective visco-elastic response binder. Among different modifiers, polymers have been very promising improving properties Ethylene Vinyl Acetate (EVA) a plastomer, obtained by co-polymerization ethylene vinyl acetate. Depending on...
This study evaluates the creep and recovery response of different asphalt binders in unaged short-term aged conditions. The multiple stress (MSCR) test has been carried out from 40 to 70°C at five levels. Two conventional, two polymer-modified, warm mix were used. Polymer modification led improvement permanent deformation characteristics binders. use zycotherm as a additive did not have any positive effect on response. temperature susceptibility increased with ageing variation Jnr levels was...
The use of waste cooking oil (WCO) and nanoclay (NC) in the modification asphalt binder can produce sustainable material for paving applications. This study evaluated change physical rheological properties attained by a conventional using varying percentages WCO NC; 0%, 2.5%, 5% was used to modify VG 30 binder, followed reinforcement four different dosages montmorillonite NC (0%, 2%, 4%, 6%). A total 12 combinations binders were produced (VG30, 2NC, 4NC, 6NC, 2.5WCO, 5WCO, 2.5WCO2NC,...
