Description

Assembled plastic base asphalt pavement structure and construction technology thereof

Technical field

The invention belongs to the technical field of road engineering, and specifically relates to an assembled plastic base asphalt pavement structure and a construction process thereof.

Background technique

Asphalt pavement has good performance such as smooth surface, no joints, comfortable driving, wear resistance, low vibration, low noise, easy maintenance and repair, etc. It is composed of asphalt as a binder to bond mineral materials to build the surface and various base layers. Pavement is the main form of pavement structure in my country. In the past 20 years, my country has built a considerable number of asphalt pavements, which are widely used on highways and urban roads. For asphalt pavement, according to the type of base material, it can be divided into flexible base asphalt pavement, rigid base asphalt pavement and semi-rigid base pavement asphalt pavement. The semi-rigid base asphalt pavement is soil or broken with inorganic binder such as cement and lime. The base layer constructed by gravel and industrial waste slag containing hydraulic binder has the characteristics of high strength and low cost, which is more suitable for China's reality. Therefore, more than 99% of the asphalt pavement base layer in China is made of cement stabilized gravel and two ash. Stable semi-rigid materials such as pellets, but the semi-rigid base is prone to cracks, and under the combined action of load, ambient temperature and other factors, the cracks in the base will gradually extend to the surface layer, forming reflective cracks, and seriously affecting the performance of the road.

Pavement is an important component of the transportation system, so the development of intelligent pavement is the focus of achieving intelligent transportation system. Literature 1 (WANG Linbing, Wang Hanxiao, Zhao Qian, Yang Hailu, Zhao Hongduo, HUANG Baoshan. Development and prospects of intelligent pavement[J].China Journal of Highway and Transport,2019,32(04):50-72.) Define intelligent pavement as specific It is composed of structural materials, perception networks, information centers, communication networks, and energy systems. It has multiple intelligent capabilities such as active perception, automatic discrimination, autonomous adaptation, and dynamic interaction, and can provide services for people, vehicles, and the environment. The intelligent pavement architecture is divided into four levels, namely the information perception and acquisition layer, the information integration processing layer, the integrated service layer and the energy supply layer. Among them, the energy supply layer refers to maintaining the operation of the intelligent system within the road area through self-supply. Specifically, it refers to the conversion of light energy, wind energy, heat energy, mechanical energy, etc. into electrical energy or direct use, and it is used as sensor devices, data base stations, Power supply for various road facilities and equipment such as traffic signs can also be used for road services such as melting snow and ice.

Therefore, it is an inevitable trend for the development of modern transportation to comprehensively solve the problems of traditional asphalt pavement and combine the current scientific and new technology to realize the intelligentization of asphalt pavement.

The structure design is reasonable, the plastic base layer is cheap, the construction is simple, and the maintenance is convenient. The insulation layer is laid on the plastic base layer to ensure that the plastic base layer is in No irreversible deformation occurs during the construction of the asphalt pavement surface layer, thus effectively ensuring the durability of the pavement structure. The metal plate is laid on the thermal insulation layer to effectively meet the requirements of the road load on the strength of the road surface. The metal plate is installed on the double-layer asphalt pavement. The installation system ensures that the asphalt pavement has good deformation followability, durability and road performance. This structure innovatively applies plastics, metal plates, and thermal insulation layers to the road structure, and reasonably considers the vehicle load during the road service period. And the impact of temperature changes on the pavement. On the basis of satisfying leveling, driving comfort, abrasion resistance, low vibration, low noise, and easy maintenance, it solves the most common problem of cracks in asphalt pavements and realizes the realization of the plastic industry and steel industry in China. The application in the transportation industry has contributed "road" power to China's industrial upgrading. The plastic base layer is used on the roadbed to replace the semi-rigid base layer in most existing asphalt pavements, which effectively solves the problem of reflective cracks caused by the semi-rigid base layer, reduces the construction cost of the asphalt pavement, saves construction time, and ensures the asphalt pavement The construction quality has subverted the traditional thinking. The plastic base material is made of waste plastic garbage. It is a hollow structure formed by compacting plastic slag after treatment, which effectively realizes waste utilization, protects the environment, and expands the "green" of asphalt pavement. "The connotation of development is that when the plastic base layer reaches its useful life, it can be recycled, broken, processed, and compacted to realize the recycling and reuse of the plastic base layer, saving a lot of resources.

Controlling the thickness of the bonding layer is to control the fluidity of the bonding material and ensure the bonding performance of the bonding material. Step 5: Prefabricating glass fiber reinforced polymer sheets in the prefabrication center saves cost, and uses split installation to ensure The installation quality speeds up the installation progress. After the installation is completed, the glass fiber reinforced polymer sheet is poured with a joint glue to form a stable overall structure; step 6 ensures the reliability of the bonding of the steel plate transition layer; proceed after step 6 Step seven is easy to operate in subsequent steps to ensure coordinated and orderly construction; Step eight fully considers the curing time of thermally conductive silicone, which saves construction time.
