Abstract
The invention discloses an indoor test operation method and device for asphalt mixture vibration mixing. Asphalt mixture vibratory mixing indoor test device includes mixing tank, rack, mixing tank vibrator, shock absorbing device, stirring motor, stirring shaft, stirring arm, stirring blade, shaft end sealing device, vibration motor, vibrator, material volume It consists of detection device, heating device, heater, electric control system, control panel and discharge door. The operation method of the vibratory mixing indoor test device for asphalt mixture realizes simultaneous heating of the mixing tank and the mixing shaft, controllable vibration frequency of the mixing tank and the shaft, controllable vibration amplitude, and controllable discharge volume. The invention is easy to operate, easy to popularize and apply, each material component is evenly redispersed, the porosity is reduced, and the mixing quality of the mixture is improved; it is of great significance for stimulating the potential of the material, improving the road performance of the asphalt pavement, and prolonging the service life of the asphalt pavement.
Description
technical field [0001] The invention belongs to the technical field of road engineering, and relates to an indoor test operation method and device for asphalt mixture vibration mixing. Background technique [0002] With the development of road construction and research in our country, according to relevant highway statistics and construction experience in various places, the main problem of asphalt pavement is the gradual damage of the road surface caused by local damage, which is often one or two years after the pavement is completed. Early failure in years or years in the form of cracks, water damage, loosening, potholes, and excessive car removal. Early failure of asphalt pavement has always been a major problem in the engineering field. The inhomogeneity of asphalt mixture is the main cause of early failure of asphalt pavement. The degree of uniformity of asphalt mixture is directly related to the mechanical properties and service life of asphalt pavement. [0003] Asph...
