“…Results of the Austroads report (2015), as well as Sabouri et al (2015a;2015b) reinforce the 76 previously published general trends that an increase in RA content leads to an increase in 77 stiffness of the asphalt, a reduction in fatigue life, and an increase in permanent deformation 78 resistance. The results do not suggest the RA content has an appreciable impact on moisture 79 sensitivity of the asphalt specimen.…”

“…Instead, when RA mixtures were manufactured with 83 even 40% of soft RA, here called "short-term aged", results of performance-related tests 84 provided evidence of a little impact of the RA. This is justified from the little differences 85 between RA and virgin materials stiffnesses (Sabouri et al, 2015a;Sabouri et al, 2015b). 86…”

“…Fatigue tests for different gradations and different mixture components were conducted, based on the stress-controlled and the strain-controlled mode, respectively [10][11][12]. Results indicated that, in the strain-controlled mode, fatigue life increases as the initial modulus decreases.…”

The fatigue properties of asphalt mixtures are important inputs for mechanistic-empirical pavement design. To understand the fatigue properties of asphalt mixtures better and to predict the fatigue life of asphalt mixtures more precisely, the energy-controlled test mode was introduced. Based on the implementation theory, the laboratory practice for the energy-controlled mode was realized using a four-point-bending fatigue test with multiple-step loading. In this mode, the fatigue performance of typical AC-20 asphalt specimens with various reclaimed asphalt pavement (RAP) contents was tested and evaluated. Results show that the variation regulation of the dissipated energy and accumulative energy is compatible with the loading control principle, which proves the feasibility of the method. In addition, the fatigue life of the asphalt mixture in the energy-controlled mode was between that for the stress-controlled and strain-controlled modes. The specimen with a higher RAP content has a longer fatigue life and better fatigue performance.

“…According to McDaniel and Anderson, the stiffness of the mixture can dramatically increase with the inclusion of RAP [27]. When using high RAP content, the fatigue resistance can be reduced due to the addition of aged binder that stiffened the mixtures [28]. Nevertheless, the addition of RH-WMA improves the fatigue resistance in comparison with a mixture containing RAP only.…”

Environmental impact and emissions produced from asphalt road construction, promote research on green materials by combining the recycling and warm mix asphalt additive which aims to reduce the environmental impacts. This study evaluates the effects high reclaimed asphalt pavement (RAP) content incorporated with wax warm mix asphalt additive. Milled reclaimed asphalt pavements obtained from local roads were incorporated with a warm mix additive named RH-WMA. These materials were evaluated for the physical and rheological properties, optimum binder content and mechanical properties. It was found that RH-WMA has softening effects on the binder. The additions of 3% RH-WMA content into 40% RAP mixture decreased the optimum binder content and energy consumption. Tests on mechanical properties indicated increased on stiffness with the addition of RAP which indicated better resistance to rutting. Additions of RH-WMA on specimens that subjected to combined effects of moisture and aging showed improvement in fatigue resistance. Hence, integration of RAP and RH-WMA showed potential as a green road construction material.
