AI Technical Summary
In existing technologies, the testing of the uniformity and stability of coarse aggregates mainly relies on visual observation, which leads to a large human factor and large deviation in results, affecting the compaction degree and void ratio control of asphalt mixtures, and thus affecting road quality.
By obtaining the apparent density and mass of coarse aggregate samples, calculating the average apparent density and total mass of each sample, determining the mass of miscellaneous stones, and then calculating the miscellaneous stone content of the coarse aggregate, a systematic approach is adopted to reduce human factors and improve detection accuracy.
This method enables objective and accurate detection of the coarse aggregate content, ensuring the accuracy of asphalt mixture testing and the quality of road construction, reducing the workload of testing, and improving the operability and objectivity of the test.
