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.

Shanghai EXPO museum is the first BIM pilot project financially invested by Shanghai government. Start with the "Cloud of celebration", this paper mainly introduces the application of BIM technology in Shanghai EXPO museum in design stage, construction stage and operational stage, as well as how to manage the models, drawings, documents and workflows in the whole life-cycle process through the collaborative platform. Application of the BIM technology has increased the capacity of project management effectively, and solved the problems at the design stage and construction stage of 'Cloud of celebration' at the same.
