Abstract
Description
technical field
[0001] The invention mainly relates to the field of road engineering design and construction, in particular to a method for testing the embedding ability of a coarse aggregate skeleton. Background technique
[0002] The strength of asphalt mixture mainly comes from two aspects: one is the cohesive force of the mixture formed by the cementing ability of asphalt to the mineral materials, and the other is the internal friction force formed by the mutual embedding of the mixture and mineral materials. For coarse aggregate dis-graded asphalt mixture, the intercalation ability of coarse aggregate with a particle size greater than 4.75 mm has a significant impact on the strength of the mixture.
[0003] Although the "embedding" ability is not a mechanical index in the strict sense, it is very important for the accumulation structure of granular particles. The mutual "occlusion" between skeleton coarse aggregate particles is one of the important factors affecting th...
