Embodiment Construction

[0029] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0030] see figure 1 , The cohesion testing device of the cold-patched asphalt mixture of the present invention includes a vibrating part, a screening part, a transfer part, a weighing part, a main control part and a support protection part. The bottom of the box is provided with a support 2, and the side is provided with a protective door 13. A protective door handle 14 is installed on the protective door 13. The support 2 is used for the instrument to be placed on the platform smoothly. The effect of bottom plate 3 is to fix the position of vibrating table and electronic scale, and provide vertical support. The function of the protection door 13 is to isolate the excessive contact between the instrument and the outside world, and reduce the impact of the instrument on the surrounding environment. The effect of dividing plate 23 is to provide the platform and the sp...

Abstract

The invention discloses a device and a method for testing the adhesive aggregation performance of a cold patch asphalt mixture. The device comprises a vibration part, a screening part, a transferring part, a weighing part, a main control part and a support protection part, and is specially designed based on the adhesive aggregation performance test of the cold patch asphalt mixture; the screening part, the weighing part and the main control part used for controlling the screening part and the weighing part are arranged in a box body, so that the device for testing the adhesive aggregation performance of the cold patch asphalt mixture can be used for easily collecting the scattered cold patch material, and is capable of quantificationally evaluating the adhesive aggregation performance of the cold patch asphalt mixture by weighing. The device is reasonable in structural design, can be used for testing the adhesive aggregation performance of the cold patch asphalt mixture, and is simple in principle, convenient to operate and easy to popularize.

Description

technical field [0001] The invention belongs to the cohesion test field of cold-patch asphalt mixture for road engineering asphalt pavement, and in particular relates to a cohesion performance test device and test method for cold-patch asphalt mixture. Background technique [0002] At present, all countries are vigorously building asphalt pavements, but a series of diseases, such as spalling and potholes, have also appeared, which seriously reduce the comfort of road use. In recent years, cold-patch asphalt mixture, which can be mixed at room temperature without heating, has received more attention due to its good adaptability. This cold patch can be used in low temperature, humid environment. However, the cohesion performance of cold-patch asphalt mixture directly affects the service performance of asphalt mixture. In order to ensure the good service performance of asphalt pavement, it is urgent to test the cohesion performance of cold-patch asphalt mixture scientifically....
