Recycled aggregate mixture and application thereof

[0034] Example 1:

[0035] A recycled aggregate mixture is composed of ordinary Portland cement, recycled aggregate, primary aggregate and primary stone powder, wherein:

[0036] The primary aggregate content is 35%-43%;

[0037] The content of the regenerated aggregate is 18%-25%;

[0038] Described primary stone powder content is 25%-27%;

[0039] The content of the regenerated stone powder is 12%-15%.

[0040] In a preferred solution, the primary aggregate has a particle size of 5mm-37.5mm, an apparent density of 2.616-2.626g / cm³, and a mud content of 0.5-1.5%.

[0041] In a preferred solution, the regenerated aggregate has a particle size of 5mm-37.5mm, an apparent density of 2.590-2.611g / cm³, and a mud content of 0.7-1.7%.

[0042] In a preferred solution, the particle size of the rough stone powder is 0-5mm, the apparent density is 2.596g / cm³, and the mud content is 3.4%.

[0043] In a preferred solution, the re-stone powder has a particle size of 0-5mm, an appar

[0044] Example 2:

[0045] The pavement structure based on the recycled aggregate mixture described in Example 1 is as follows:

[0046] Two layers of recycled aggregate mixture are spread on the compacted soil base to form a sub-base 1 and a base 2, a concrete cushion 3 is poured on both sides of the base 2, and a cement mortar 4 is poured above the concrete cushion 3, and then the vertical teeth 5 are set. Between the vertical teeth 5 on both sides of the base layer 2, from bottom to top, emulsified asphalt permeable layer 6, coarse-grained asphalt concrete 7, medium-grained modified asphalt concrete 8 and asphalt mastic crushed stone mixture 9 are sequentially paved.

[0047] Example 3:

[0048] The specific ratio of the sub-base 1 and the base 2 and the cement content are determined through experiments:

[0049] The sub-base layer 1 is paved with 4% cement-stabilized recycled aggregate mixture (the cement content is 4%), and the base layer 2 is paved with 5% cement-stabilized recycled aggregate mixture (the cement content is 5%).

[0050] Specifically, in the sub-base 1, the recycled aggregate mixture is a 4% cement-stabilized recycled aggregate mixture, including:

[0051] Primary aggregate, the particle size is 5mm-37.5mm, the content is 35%, the apparent density is 2.616-2.626g / cm³, and the mud content is 0.5-1.5%;

[0052] Recycled aggregate, particle size is 5mm-37.5mm, content is 25%, apparent density is 2.590-2.611g / cm³, and mud content is 0.7-1.7%;

[0053] Primary stone powder, particle size 0-5mm, content of 25%, apparent density of 2.597g / cm³, and mud content of 3.2%;

[0054] Recycled stone powder, particle size 0-5mm, con
