Pitch spaying amount testing method and device

Abstract

The invention discloses a pitch spraying amount testing method and device.The method comprises the steps that a container with the specified containing area is arranged on the road surface where pitch needs to be sprayed, a weighing device is arranged on the container, efficient and rapid weighing is achieved, a sample collecting barrel for storing the weighed pitch is arranged below the container, a spraying system is connected to the sample collection barrel, and the spraying system is utilized for spraying the collected pitch to the road surface below the container.A conventional pitch spraying amount detecting method and national standards are broken through for the first time, the method and device capable of achieving in-situ weighing and evenly spraying the weighed pitch to the original area are provided, the whole testing working procedure and flow are simplified, the efficiency is improved, and the filling working procedure for pitch in a detection area in the later period can be omitted.

Description

technical field [0001] The invention relates to a method and a device for testing the amount of asphalt spraying, and belongs to the field of detection of highway engineering site construction. Background technique [0002] The multi-layer elastic layered system is the design theory system of asphalt pavement in my country. In actual construction, it is necessary to keep the continuous state between the layers of the structure as much as possible to avoid the sliding displacement between the layers and maintain the integrity of the pavement structure. At present, in the design and construction of asphalt pavement in my country, functional layers such as permeable layer and sticky layer are used to bond each structural layer of the pavement into a whole, so as to better meet the requirements of design theory. [0003] The permeable layer is an organic binder permeable layer on the top surface of the inorganic binder base, used as an interlayer treatment between the lower laye...

AI Technical Summary

Problems solved by technology

This test method has the following deficiencies: (1) The sampling process will damage the integrity of the sprayed asphalt sticky layer and permeable layer

(2) After the test, it is necessary to sprinkle the area covered by the enamel plate or kraft paper, and it is difficult to guarantee the spraying amount and uniformity

(3) The weighing process is likely to cause asphalt loss and cause weighing errors

When the enamel plate is used, the mass needs to be weighed immediately after receiving the asphalt, and the enamel plate needs to be manually moved from the range of the road surface where the asphalt has just been sprinkled to outside the range of the road surface, which is not easy to operate

When kraft paper is used, it is necessary to wait for the asphalt to solidify slightly and lift the four corners slightly to weigh. Waiting for the asphalt to solidify slightly will cause loss of asphalt quality

(4) The test process is relatively cumbersome and needs to be calculated later, and kraft paper cannot be reused
