“…As the high-temperature performance parameter of asphalt, the larger the rutting factor G * /sinδ is, the smaller the energy dissipation is, and the smaller the permanent deformation of asphalt at high temperature is [33]. It can be seen from the analysis in Figure 5(b) that for the rutting factor of high modulus asphalt, the smaller quartile Q1 of the basic modified high modulus asphalt is 1.02 kPa, the median Q2 is 1.63 kPa, and the larger quartile Q3 is 2.45 kPa, and 50% of the rutting factor of high modulus asphalt is between 1.02 kPa and 2.45 kPa, indicating that the difference in the research results of different units can reach 1.43 kPa or more.…”

With the increase in traffic volume and axle load, the requirement of road quality is continuously improving, and high modulus asphalt has attracted the attention of researchers due to its excellent road service performance and economic benefits. In order to further improve the durability and use quality of Chinese roads, realize the scientific evaluation of the performance of high modulus asphalt and its mixture, and further promote the development of high modulus asphalt technology in China, the performance indexes of high modulus asphalt and its mixture in China were comprehensively investigated. The differences in high- and low-temperature performance of matrix asphalt, basic modified high modulus asphalt, and composite modified high modulus asphalt were compared and evaluated. Based on the results of mathematical statistics and the relevant specifications of high modulus asphalt in China, the performance grades of high modulus asphalt and its mixture were proposed. The results showed that compared with the basic asphalt, the softening points of the basic modified high modulus asphalt and the composite modified high modulus asphalt were increased by 18.76% and 82.89%, respectively, and the rutting factors were increased by 2 and 9 times, respectively, but the improvement effect of the low-temperature performance of the high modulus asphalt was not obvious. Based on the data statistics node and relevant Chinese regulations, high modulus asphalt and its mixtures were divided into four grades: excellent, good, fair, and poor, aiming to provide scientific suggestions for the wide application of high modulus asphalt.

“…The research of Sybilski et al [9] showed that the limestone minerals could be suitable for HMAC aggregate. The usage of HMAC in asphalt pavement structure allows reduction in comparative deformations and to slower deformation timing, at the same time increasing rutting resistance and durability [16].…”

“…HMAC could be used for the construction of asphalt binder and base layers. For this purpose, the special bitumen binders and the optimal composition of aggregates (which could consist of weaker mineral aggregates), are used [3][4][5][6][8][9][10][11][12][13][14][15][16][17][18]. Viscous elastic properties of asphalt materials are significantly influenced by temperature.…”

High value of traffic flow influenced the need to build long lasting pavement structures with design life of more than 20-40 years. Current budget for maintenance and reconstruction is not sufficient for preventing the rutting on the existing asphalt pavement roads and streets. These factors lead to search for new materials, mixtures, and methods for preparation of asphalt mixes. The high modulus asphalt concrete is regarded as one of possible solutions. The laboratory study of the high modulus asphalt concrete with different types of bitumen binder and mineral aggregates is presented in the paper.

“…Garba [21][22][23] investigated the influence of load, temperature, and mixture type on the permanent transformation of hard petroleum asphalt mixture, and through a triaxial test and a creep recovery test, the prediction model and method for determining the permanent deformation of the hard petroleum asphalt mixture were obtained. Ouyang et al [24] proposed the improvement of asphalt pavement rutting by enhancing the modulus of the asphalt mixture, and the results showed that the application of hard petroleum asphalt to intermediate layers could maximize the reduction of pavement rutting. Wu et al [25] tested the dynamic modulus and fatigue parameters of asphalt mixture with high modulus (AC20, Sup20, and EME20) prepared hard petroleum asphalt, based on LPC asphalt mixture design guidelines.…”

Hard petroleum asphalt, which is a high modulus asphalt binder material, is used for improving asphalt pavement rutting distress. This property is attributed to the good high-temperature rheological characteristics of hard petroleum asphalt. The study investigates the performance of hard petroleum asphalt and Styrene-Butadiene-Styrene polymer modified asphalt (SBSPMA) based on three aspects: asphalt oil source, asphalt grade, and aging degree. The short-term and long-term aging of four hard petroleum asphalts and SBSPMA of comparative samples were measured using the rolling thin film oven test (RTFOT) and the pressure aging test (PAV). Firstly, the viscosity-temperature curve of hard petroleum asphalt was obtained using the Brookfield viscosity test at different temperatures combined with the improved REFUTAS formula. The complex shear modulus ( G ∗ ), phase angle (δ), and rutting factor ( G ∗ / sin δ ) of each asphalt sample were then measured by the dynamic shear rheometer test (DSR). Furthermore, the temperature sensitivity of each asphalt sample was calculated using the complex modulus index method (GTS). The compaction and paving temperature ranges of each asphalt were then confirmed. The results showed that the high-temperature rheological characteristics of hard petroleum asphalt were similar to those of SBSPMA. The temperature sensitivity of hard petroleum asphalt was basically the same as that of SBSPMA, while the influence of aging on the G ∗ of hard petroleum asphalt was greater than that of SBSPMA. In addition, the hard petroleum asphalt construction temperature was lower than that of SBSPMA.
