“…The low viscosity of low-grade asphalt mixtures facilitates the formation of a dense asphalt film at high temperatures, thereby enhancing pavement shear and deformation resistance. NASCIMETO et al [6] focused on hard asphalt mixtures as their primary research subject and assessed them using the Hamburg rutting test, which revealed excellent resistance to high-temperature deformation.…”

This study investigates the feasibility of low-grade hard asphalt in high-temperature regions. We conducted an analysis of the high-temperature rheological properties of asphalt before and after short-term and long-term aging using the dynamic shear rheological (DSR) test and multi-stress creep recovery (MSCR) test. Additionally, the road performance of the asphalt mixture was studied by rutting test and low temperature beam bending test. The results indicate that the 30# asphalt demonstrates superior anti-rutting performance compared to the 50# asphalt. Furthermore, the rutting factor and fatigue factor of the 30# asphalt during aging are significantly higher than those of the 50# asphalt. With increasing temperature, stress level, and stress action time, the strain of the asphalt gradually increases. The unrecoverable creep compliance of the 50# asphalt exceeds that of the 30#. Although the high-temperature performance of the 30# asphalt mixture outperforms that of the 50# asphalt mixture, it exhibits lower flexural tensile strength and deformation ability at low temperatures compared to the 50# asphalt mixture. Overall, low-grade asphalt demonstrates relatively stable stress variations and exhibits good high-temperature stability.

“…The IDT test is a test method developed by the Texas Transportation Research Center for evaluating the crack resistance of asphalt mixtures [ 30 ]. When it is used to evaluate the crack resistance of asphalt mixtures at low temperatures, a temperature of −10 °C ± 0.5 °C and a loading rate of 1 mm/min should be adopted.…”

With the promotion of cold recycled mixture (CRM) in cold areas and the improvement of its application layer, the enhancement of the low-temperature performance of mixtures is particularly important. The applicability of the current low-temperature bending test method to CRM is controversial. Firstly, the low-temperature crack resistance of CRM with different gradations and emulsified asphalt contents was studied by the indirect tensile (IDT) test and the semi-circular bending (SCB) test. Thereafter, the low-temperature performance evaluation index suitable for CRM was put forward. Then, the low-temperature performance of CRM with different gradations, fiber types, and contents was evaluated by using the above low-temperature evaluation index. The results show that the low-temperature performance of CRM with different gradations and emulsified asphalt contents can be distinguished by fracture work (W) and fracture energy (Gf). Not only do the test results have little variability (about 12% and 15%, respectively), but also the correlation coefficient with the new asphalt film thickness is the highest (0.8595 and 0.8939, respectively). Compared with coarse gradation (AC-25) and fine gradation (AC-13), medium-gradation (AC-20) CRM has higher low-temperature performance, and polyester fiber can significantly improve the low-temperature performance of CRM. Compared with non-fiber, the W and Gf of CRM of polyester fiber (0.3% content) can be increased by at least 42% and 30%, respectively.

“…Permanent deformation is damage to the asphalt mixture in the pavement structure. The factors that cause this damage are traffic loads, mixed design, environmental factors, and so on [1]. Asphalt, which has an important role in determining the durability of pavement performance, has a service life according to traffic needs and conditions.…”

“…The damage usually starts with micro-cracks and progresses to more complex damage such as permanent deformation [3]. Because the crack problem disappears, it can trigger new problems, namely permanent deformation [1]. A researcher stated that the addition of alginate to the mastic asphalt mixture could heal micro-cracks so that it could maintain a low pavement life [4].…”

This paper discusses natural asphalt deposits of Buton stone (asbuton) in Indonesia are very abundant, but the characteristics of asbuton are not yet suitable for road applications. So that the use of asbuton as a binder needs to be added with additives that can react independently to overcome the permanent deformation such as the addition of calcium alginate microcapsules to the asphalt mixture. The purpose of this study was to determine the effect of adding calcium alginate microcapsules to the permanent deformation of AC-WC with asbuton. The current problem is that road pavements are not able to heal themselves when cracks start to occur, so additional materials are needed that can stimulate self-healing to occur so that the cracks that have started to occur can be closed again even though it takes time so that the self-healing process can occur. The microcapsules are made with the main ingredients of water, sunflower oil, sodium alginate (C6H7O6Na) and calcium chloride solvent (CaCl2), which are encapsulated and embedded in the asphalt mixture as a material that can restore the structural function by a healing method self healing. The research method uses true experimentally. Specimen variations in the study were the addition of calcium alginate microcapsules of 0 %, 1 %, 1.5 %, 2 %. Wheel Tracking Testing was carried out with the AASHTO Standard: T 32-11 and CAL Testing with the Tex-245-F 2014 standard. The results showed that with the addition of calcium alginate microcapsules, there was no significant contribution; better than microcapsules, the mixture decreases in the number of passes so that the mixture is easy to change shape rutting. However, adding calcium alginate microcapsules can reduce the value of weight loss, causing the adhesion of the asphalt mixture to increase
