Description

Technical Field

[0001] This utility model belongs to the field of highway technology, specifically relating to a side limiting device for cement-stabilized crushed stone base course of highways. Background Technology

[0002] Cement-stabilized crushed stone uses graded crushed stone as aggregate, with a certain amount of cementitious material and sufficient mortar volume to fill the voids in the aggregate, and is spread and compacted according to the interlocking principle. Its compaction degree is close to its density, and its strength mainly relies on the interlocking and bonding principle between the crushed stones, while sufficient mortar volume fills the voids in the aggregate. It has high initial strength, and its strength increases rapidly with age, quickly forming a slab, thus possessing high strength, good impermeability, and good frost resistance. The cement content in cement-stabilized crushed stone is generally 3%~6% of the mixture, and its 7-day unconfined compressive strength can reach 5.0 MPa, higher than other subgrade materials. After cement-stabilized crushed stone is established, it does not become muddy after rain, and its surface is firm, making it an ideal base course material for high-grade pavements.

[0003] When using existing devices, the baffles on both sides of the laying device need to be manually pulled and adjusted, which is laborious and inconvenient; there are gaps between the baffles and the ground, which may make the device unstable when moving and require support.
