Abstract

The invention discloses an automatic Marshall compaction device and a test method. The automatic Marshall compaction device comprises a controller and a supporting part, wherein the supporting part is used for adding an asphalt mixture; a safety protection part and an inserting and tamping rod are arranged on the supporting part; the inserting and tamping rod is used for uniformly inserting and tamping the asphalt mixture; a compaction part which is used for compacting the asphalt mixture is arranged above the safety protection part; a power part which is used for driving the compaction part to operate is connected to the compaction part. According to the automatic Marshall compaction device, the supporting part which is used for adding the asphalt mixture and the compaction part which is used for compacting the asphalt mixture are controlled through the controller, and the compaction part is driven by the power part to repeatedly compact the asphalt mixture. The automatic Marshall compaction device is simple in design and convenient to use, a rotary shaft can be conveniently rotated, the inserting-tamping compaction time is shortened, and the compaction efficiency is improved.

Description

technical field [0001] The invention belongs to the compaction field of asphalt mixture in road engineering asphalt pavement, and in particular relates to a Marshall automatic compaction device and a test method. Background technique [0002] With the continuous development of asphalt pavement theory, more and more asphalt tests need to be designed for verification. Currently, Marshall specimens are widely used in asphalt tests because of their good adaptability. However, in the current production process of Marshall specimens, compaction is relatively time-consuming, especially when the front and back sides are alternately struck. In consideration of shortening the compaction time, it is necessary to improve the current compaction equipment. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, and provides a Marshall automatic compaction device and test method, the device has a simple structure, the test method is easy t...
