Forming equipment for asphalt mixture test piece and using method

Abstract

The invention discloses forming equipment for an asphalt mixture test piece and a using method. A discharging device comprises a material containing device which is through up and down, and stirring blades are arranged in the material containing device; a rolling forming device comprises two threaded rods, two limiting rails, a rolling wheel and a telescopic device used for applying pressure to the rolling wheel, forward threads are formed in each threaded rod from one end to the middle of the threaded rod, reverse threads are formed in each threaded rod from the other end to the middle of thethreaded rod, the two threaded rods are oppositely arranged in parallel, and the two threaded rods can synchronously rotate around the axes of the threaded rods; the two ends of one limiting rail arecorrespondingly connected with the forward threads of the two threaded rods in a matched mode, and the two ends of the other limiting rail are correspondingly connected with the reverse threads of the two threaded rods in a matched mode. The rolling wheel stretches across the two limiting rails, the telescopic device is arranged above the rolling wheel, the two ends of the rolling wheel are rotationally connected with telescopic rods of the telescopic device, and the telescopic device can reciprocate in the direction of the limiting rails. The influence of personal errors is reduced, and theforming efficiency of the test piece is improved.

Description

technical field [0001] The invention belongs to the field of road engineering tests, and in particular relates to a forming device and a using method of an asphalt mixture test piece. Background technique [0002] As one of the main paving materials for high-grade pavement, asphalt mixture has been widely concerned and researched for its excellent performance, convenient paving, convenient maintenance and good comfort. Nowadays, more and more high-performance pavement and functional pavement come into people's field of vision, and the construction technology and equipment of asphalt pavement tend to be perfected. [0003] In the indoor asphalt mixture performance test, the compaction method and the traditional wheel mill are usually used to form the test piece, but both have their own shortcomings. The compaction method cannot simulate the actual road surface rolling process well, and the compaction hammer is still It may cause stone crushing; the size of the traditional wh...

Problems solved by technology

[0003] In the indoor asphalt mixture performance test, the compaction method and the traditional wheel mill are usually used to form the test piece, but both have their own shortcomings. The compaction method cannot simulate the actual road surface rolling process well, and the compaction hammer is still It may cause stone crushing; the size of the mold of the traditional wheel mill is fixed, which can only meet the requirements of a small number of tests, and only one rut plate can be formed at a time, which is not efficient

In addition, both of these two methods require manual filling of the mixture, which is greatly influenced by human factors, which is likely to cause uneven loading, layered segregation, etc., resulting in differences between test pieces and adverse effects on test results.
