Thermoreversible aging
Webb28 apr. 2024 · For bituminous bound materials, the aging of asphalt binder has a crucial impact on durability and recyclability. Because asphalt binder is organic by nature, the thermal and oxidative aging processes affected by chemical and structural changes occur when asphalt mixes first are produced and applied and continue over the course of their … WebbInfluence of Aging Time at 20’C The results presented in Figure 2 were compared with results obtained from experiments in which the aging time at 20°C was 1 day instead of 3 days. The results indicated that melting points do not differ within the accuracy of the experiment. At relatively high water content of 20% the

Webb14 juni 2024 · To sum up, most of the existing studies on the wax of asphalt only focus on the wax-based mixture side, analyzing the effect of wax on the thermoreversible aging and moisture sensitivity of asphalt, but not the effect of the molecular weight distribution and branching of wax on the moisture sensitivity of asphalt binder. Webb12 feb. 2024 · Materials were aged in the pressure aging vessel and investigated by infrared spectroscopy, modulated differential scanning calorimetry, and dynamic shear …
WebbAdditionally, an aging gradient was found within the asphalt layer, indicating that the degree of aging is spatially dependent and the most severe aged material is located in the surface layer. This aging gradient was also reported by Soenen et al. (Citation 2024), who investigated 15 different recovered binders with a service life of 8–21 years. WebbThe analyses and conclusions of this study may be 1) industrially relevant to products that age on commercial timescales, such as paints and pharmaceuticals, 2) applicable to other dynamically arrested systems, such as metallic glasses, …
