Asphalt concrete quality monitoring method and equipment thereof

Abstract

The invention relates to an asphalt concrete quality monitoring method and equipment. The method comprises the following steps: acquiring a sample, and collecting sand grains screened out in an asphalt concrete production process; screening sand grains, and screening the sand grains into materials with different particle size ranges; weighing the materials, and obtaining the weights of the materials in different particle size ranges through weighing; calculating the numerical value to obtain the proportion of the materials in different particle size ranges in the total sample amount; comparing the numerical values, comparing the proportions of the materials in different particle size ranges in the total amount of the sample with a qualified range, and when the proportion of the material in at least one particle size range in the total amount of the sample exceeds the qualified range or is lower than the qualified range, remaining the produced asphalt concrete in an asphalt concrete plant to wait for reprocessing; and when the proportions of the materials in different particle size ranges in the total amount of the obtained sand grains are all within the qualified range, allowing the asphalt concrete to be transported out of a factory. The method has the effect that the situation that unqualified asphalt concrete is transported out of a factory after being produced is reduced.

Description

technical field [0001] The present application relates to the technical field of quality monitoring, in particular to a method and equipment for monitoring the quality of asphalt concrete. Background technique [0002] Asphalt concrete, commonly known as asphalt concrete, is artificially selected mineral materials with a certain gradation composition (crushed stone or crushed gravel, stone chips or sand, mineral powder, etc.) and a certain proportion of road asphalt materials, under strict control conditions Blended mixture. [0003] The production process of asphalt concrete usually includes drying and heating cold aggregates, screening hot aggregates, subpackaging hot aggregates, measuring hot aggregates, adding asphalt and mineral powder and mixing, and asphalt concrete leaving the factory; among them, screening hot aggregates The material is to convey the hot aggregate to the screening machine, so that the hot aggregate is screened into coarse grains (below 25-40 mm), m...

AI Technical Summary

Problems solved by technology

[0004]Because the produced asphalt concrete is time-sensitive, the asphalt concrete needs to be transported to the construction site in time to keep the asphalt concrete at a suitable temperature, so after the asphalt is produced, Quality inspection of it will often affect the timeliness of asphalt concrete; and the asphalt concrete production process lacks monitoring of asphalt concrete quality. When the asphalt concrete is used and it is found not to meet the construction requirements, the asphalt concrete factory needs to pay for cleaning. Unqualified asphalt concrete used in construction will cause considerable economic losses to the asphalt concrete plant
