Laboratory fatigue evaluation of modified and unmodified asphalt binders in Stone Mastic Asphalt mixtures using a newly developed crack meander technique

Experimental investigation on mineral and organic fibers effect on resilient modulus and dynamic creep of stone matrix asphalt and continuous graded mixtures in three temperature levels

“…Marshall Stability and Resilient modulus of SMA specimens were reported more than HMA control specimens in this research [18]. Same fiber (COPF) was used and compared with Ethylene Vinyl Acetate (EVA) as selected asphalt modifiers in other study [13]. Tire rubber was used in a laboratory study to investigate moisture susceptibility and rutting resistance of stone matrix asphalt [4].…”

“…The comparison was performed at three temperature levels of 5°C, 25°C and 40°C [12]. Muniandy et al studied the fatigue behavior of modified and unmodified asphalt binder in SMA [13]. Behnood and Ameri conducted an evaluation on SMA containing steel slag [14].…”

“…Also stabilizing methods on SMA mixtures were evaluated by Lyons and Putman [21]. Study result by Muniandy et al [13] showed the non-modified SMA has the longest crack length while EVA showed the less crack length. In Oda et al [20] all fibers showed excellent tensile performance.…”

The influence of temperature on the fatigue behaviour of bituminous materials for pavement rehabilitation

“…Several studies have assessed the mechanical performance of these bituminous materials against fatigue and cracking (Wong & Suo 2009;Moghadas et al, 2010;Hintz & Bahia, 2013;Muniandy et al, 2014). As expected, due to the presence of high dosages of bitumen, their resistance is considerably higher than that offered by other types of bituminous mixtures.…”

Sensitivity analysis of dynamic response and fatigue behaviour of various asphalt concrete mixtures

“…15 Zhang et al 16 investigated the permanent deformation and fracture resistance using dynamic modulus test and concluded that dynamic modulus and phase angle of the asphalt mixtures remained constant with the load cycles. Muniandy et al 17 investigated the effect of the unmodified and modified asphalt binder in stone mastic asphalt mixtures by the use of crack meander technique, compared crack analysis with tensile strain and concluded that crack appearance can be used as a surrogate to determine fatigue behaviour instead of strain/ dynamic modulus. Zhao et al 18 constructed the triaxial master curves for three asphalt mixtures and proposed a model of vertical shift factor, which was a function of reduced frequency and confining pressure.…”
