[0028] A preparation of a semi-rigid building solid waste self-maintaining roadbed, comprising the following steps:
[0029] (1) Destroy the construction waste into aggregates with a particle size of 5-40mm, and place the broken aggregates in a tube mill without grinding bodies and stir for 10 minutes, so that the fragile cement blocks in the aggregates can be ground and sieved and pre-wetted with 30% water of aggregate mass to obtain recycled aggregate.
[0030] (2) The raw materials are weighed according to the following mixing ratio: P.O 42.5 5% of cement, 5% of lime, 60% of recycled aggregate, 30% of crushed stone, and water is 8% of the solid mass of the first three.
[0031] (3) Mix cement, lime, crushed stone and recycled aggregate evenly; then add water and mix evenly to get the product.

[0033] A preparation of a semi-rigid building solid waste self-maintaining roadbed, comprising the following steps:
[0034] (1) The construction waste is broken into aggregates with a particle size of 5-40 mm, and the broken aggregates are placed in a tube mill without grinding bodies and stirred for 10 minutes, so as to grind and screen the fragile cement blocks in the aggregates , and pre-wet with 30% water of aggregate mass to obtain recycled aggregate.
[0035] (2) The raw materials are weighed according to the following proportions: P.O 42.5 5% of cement, 5% of lime, 60% of recycled aggregate, 30% of crushed stone, water is 15% of the first three solid masses, and the addition of PVA fiber is 0.8kg / m 3 , The amount of super absorbent resin added is 0.6kg / m 3 .
[0036] (3) Mix cement, lime, gravel and recycled aggregate evenly; add PVA fiber and superabsorbent resin and mix evenly; then add water and mix evenly to get the product.
