DETAILED DESCRIPTION
[0022] The utility model will be specifically introduced below in combination with the drawings and specific embodiments.
[0023] High modulus asphalt mixture is a kind of asphalt mixture by using specific raw materials, scientific and reasonable design, its remarkable feature is with high dynamic modulus, this means that under the action of vehicle load and other external force, can show stronger deformation resistance, simply speaking, ordinary asphalt mixture can appear rut, deformation and other conditions under the repeated rolling of vehicle, and high modulus asphalt mixture can better keep the flatness and stability of pavement.
[0024] High modulus asphalt mixture generally uses hard asphalt, which has a higher softening point and viscosity than ordinary asphalt, allowing the asphalt to maintain good bonding properties at high temperatures and not easily flow, thus effectively supporting the aggregate and enhancing the overall stability of the mixture. For example, some high modulus asphalt mixtures use 70# asphalt with a smaller penetration or harder asphalt varieties to meet their high modulus performance requirements.
[0025] The aggregate occupies an important proportion in high modulus asphalt mixture and is generally selected from hard, wear-resistant, and angular stone. High-quality aggregate can provide a good interlocking structure for the mixture, enhancing its resistance to external forces. Commonly used aggregates include basalt and diabase, which have high compressive strength and good adhesion to asphalt, effectively improving the durability and skid resistance of the mixture. Mineral powder, as an important filler in asphalt mixture, is also indispensable in high modulus asphalt mixture. It can fill the voids between aggregates and form asphalt mortar with asphalt, improving the performance of asphalt. The small particle size and large specific surface area of mineral powder allow it to fully contact and react with asphalt, increasing the viscosity and strength of asphalt mortar and thus enhancing the modulus of the entire mixture.
[0026] The most prominent performance of high modulus asphalt mixture is its high dynamic modulus, which enables it to effectively resist deformation of the pavement under high temperature and heavy load conditions. According to relevant research, the dynamic modulus of high modulus asphalt mixture can be 30%-50% higher than that of ordinary asphalt mixture, significantly improving the load-bearing capacity of the pavement and reducing the occurrence of rutting, heaving, and other diseases. Due to the increasing traffic flow and increasing vehicle load, the fatigue resistance of pavement materials is crucial. High modulus asphalt mixture, with its reasonable composition and material properties, can effectively disperse stress and delay the development of fatigue cracks when subjected to repeated loads. In actual road use, the fatigue life of pavement paved with high modulus asphalt mixture can be extended by 2-3 times compared to ordinary pavement.
[0027] Despite the use of special materials such as hard asphalt in high modulus asphalt mixture, its workability during construction can still be good through reasonable mix design and the use of additives. Construction personnel can perform operations such as paving and rolling as with ordinary asphalt mixture, ensuring construction quality and improving construction efficiency. The gradation design of high modulus asphalt mixture is reasonable, forming a relatively dense structure after compaction that effectively prevents water infiltration. Good water sealing performance can prevent strength reduction and loosening of the pavement due to water damage, extending the service life of the pavement. Relevant test data shows that the water permeability coefficient of high modulus asphalt pavement can be controlled at a low level, significantly reducing the erosion of surface water on the base and subgrade compared to ordinary asphalt pavement.
[0028] On heavy traffic roads, the vehicle load is large, the driving frequency is high, and the performance requirements of the pavement material are extremely harsh. High modulus asphalt mixture can withstand repeated rolling of heavy vehicles, effectively resist rutting and deformation, and ensure the flatness and safety of the pavement. Therefore, in the construction of roads with heavy traffic such as ports and mines, high modulus asphalt mixture has been widely used. Municipal roads not only have to bear the daily traffic flow, but also have to consider the influence of surrounding environmental factors. The good workability, water sealing performance and fatigue resistance of high modulus asphalt mixture make it very suitable for the construction of municipal roads. It can reduce the impact of road construction on the surrounding residents' life, improve the performance and aesthetics of the road, and provide reliable protection for urban traffic. Bridge deck pavement directly bears the load of vehicles and environmental factors, and due to the particularity of bridge structure, the performance requirements of paving materials are higher. High modulus asphalt mixture has high strength and anti-deformation ability, which can adapt to the vibration and deformation of the bridge during vehicle driving. At the same time, its good water sealing performance can prevent water from penetrating into the bridge structure and corroding the steel bars, prolonging the service life of the bridge. In many large bridge deck pavement projects, high modulus asphalt mixture has become the first choice of materials.

[0038] During work, the worker first pours the high modulus asphalt mixture into the spiral extrusion cylinder 6 through the feeding hopper 7, and then starts the driving motor 22, so that the driving motor 22 drives the extrusion screw 23 to rotate, the extrusion screw 23 performs spiral extrusion on the high modulus asphalt mixture in the spiral extrusion cylinder 6, and the mixture is preliminarily extruded and pushed to advance the feeding, so that the mixture enters the stirring tank 4 through the connecting pipe 17.
