Asphalt mixture vibrating mixing indoor test operation method and device

Abstract

The invention discloses an asphalt mixture vibrating mixing indoor test operation method and an asphalt mixture vibrating mixing indoor test device. The asphalt mixture vibrating mixing indoor test device consists of a mixing tank, a machine frame, a mixing tank vibrator, a vibration-absorbing device, a stirring motor, stirring shafts, stirring arms, stirring blades, a shaft end sealing device, avibrating motor, a vibration exciter, a material quantity detecting device, a heating device, a heater, an electrical control system, a control panel and a discharge door. By the operation method of the asphalt mixture vibrating mixing indoor test device, simultaneous heating of the mixing tank and the stirring shafts is achieved, the vibrating frequency of the mixing tank and shaft bodies can becontrolled, the vibrating amplitudes can be controlled, and the discharge amount can be controlled. The asphalt mixture vibrating mixing indoor test device is convenient to operate and easy to popularize and apply; each material component is redispersed uniformly, the void ratio is reduced, and the mixing quality of a mixture is improved; and the asphalt mixture vibrating mixing indoor test deviceis of a great significance in stimulating the potential of materials, improving the road performance of an 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...
