“…In addition, various statistical analyses, machine learning, and optimization methods are recommended for further investigation [27][28][29][30][31][32][33][34]. Pavement failures can endanger trafc safety, and various additives and nanomaterials can be taken into account in this regard, which can be examined in a feld investigation that is in line with this study [35][36][37][38][39][40]. Simulation devices and vehicles can also be adopted in incorporation with the Internet of Tings (IoT), vehicle-mounted equipment, and sensors to develop the potential of driver motion and physiological signal monitoring [41][42][43][44][45].…”

A horizontal curve’s geometric design is considered an important factor in highway accidents, and simple and spiral curves are regarded as the most common types of horizontal curves. Various factors affect the safety of horizontal curves, one of the most important of which is the side friction factor in the horizontal curves. Therefore, in this study, the safety of simple and spiral horizontal curves was investigated for the E-class sedan, E-class SUV, and two-axle conventional truck based on the side friction factor. In this regard, CarSim and TruckSim vehicle dynamic simulation software were utilized using 360 scenarios, including vehicle speed, vehicle type, curve radius, and road geometry. It was revealed that the maximum side friction factor for all vehicles in the simple horizontal curve was higher than the spiral horizontal curve. Also, the process of increasing the side friction factor was carried out with a gentler slope in the spiral horizontal curve. Except for the radius of 0.7 times the maximum radius of the spiral horizontal curve (R) for the truck and the radii of 0.7 R and 0.9 R for the sedan and SUV, the maximum side friction factor in simple and spiral horizontal curves was lower than the AASHTO recommended values, which shows that the spiral horizontal curve was better and safer compared to the simple horizontal curve based on the side friction factor.

To enhance the moisture damage performance of hot mix asphalt (HMA), treating the aggregate surface with a suitable additive was a more convenient approach. In this research, two types of aggregate modifiers were used to study the effect of moisture damage on HMA. Three different aggregate sources were selected based on their abundance of use in HMA. To study the impact of these aggregate modifiers on moisture susceptibility of HMA, the indirect tensile strength test and indirect tensile modulus test were used as the performance tests. Moisture conditioning of specimens was carried out to simulate the effect of moisture on HMA. The prepared samples’ tensile strength ratio (TSR) and stiffness modulus (Sm) results indicated a decrease in the strength of the HMA after moisture conditioning. After treating the aggregate surface with additives, an improvement was seen in dry and wet strength and stiffness. Moreover, an increasing trend was observed for both additives. The correlation between TSR and strength loss reveals a strong correlation (R2 = 0.7219). Also, the two additives indicate increased wettability of asphalt binder over aggregate, thus improving the adhesion between aggregate and asphalt binder.

“…Thus, researchers have conducted extensive tests to distinguish the causes of failure and maintenance methods [1,2], which can be used to achieve further benefits from this national treasure. Considering that most of the main roads are paved by hot mix asphalt, studies about the properties of asphalt mixtures have significant importance [3].…”

This research aims to study the bitumen structure components and tests to get a better understanding of bitumen, which is one of the main components of asphalt mixtures. In this work, a brief explanation of other research findings on the organic compound was investigated. Moreover, a review of previous research conducted with bitumen that was modified with different oils was made, eventually. By comparing the results of this study and previous studies, it can be concluded that samples containing rhamnolipid biosurfactant had a better behavior against fatigue compared to samples made with bitumen modified with other oils. The present project was equipped with Remote Sensing (RS) facilities, sensors, modems and a data logger system. Modern technology through advanced sensors and modems was applied for the detection of asphalt mixtures data.
