In order to study the application technology of ATB-25 asphalt stabilized macadam mixture on asphalt pavement in depth, this paper firstly selected the raw materials and grading of the test, and designed the target mix ratio of ATB-25 through the Marshall test. The road performance of ATB-25 mixture was studied through indoor test to determine the high temperature stability, low temperature crack resistance and water stability. In view of the ATB-25 asphalt stabilized macadam mixture, the construction technology of ATB-25 upper base is also discussed from different aspects, from the beginning of mixing to the joint treatment after the completion of rolling. The results show that the best oil-stone ratio of ATB-25 asphalt stabilized macadam mixture production ratio is 3.7%. The ATB-25 asphalt stabilized macadam mixture possesses good road performances, and can be applied to the base layer on asphalt pavement. The study result is of great significance to improve the structural performance of asphalt pavement and prevent the occurrence of reflective cracks in the base layer.

With the upgrading of building industry, intelligent construction and intelligent operation and maintenance, it has been a trend to deepen the application of BIM technology in construction projects. Taking the large-scale industrial park project as the research object, this paper gets rid of the difficulty of positioning and integrating the group project model by using the method of shared coordinates in BIM software. In the aspect of deepening mechanical and electrical pipelines, the visual programming software Dynamo plug-in is used to realize the color filling of different beam heights with one-key operation according to the complex characteristics of basement elevation changes. What's more, the clearance under the beam is intelligently analyzed, so as to provide a basis for the comprehensive layout of electromechanical pipelines. The research results can provide reference for similar projects.

In recent years, with the guidance of national policies and industry trends, there are increasing prefabricated projects. Combining the BIM technology with project management, this paper puts forward the use of BIM technology to solve fabricated generally encountered in the process of project construction tower crane selection, precasting yard, prefabricated management solutions and prefabricated construction quality problems, which expects to provide certain reference for future engineering practice and promote the further development of BIM technology.
