Application of Small Road Rollers in Subgrade Construction
Release time:2022-12-12
Small road rollers play a crucial role in road construction, and different stages of the project call for distinct considerations. Below is an overview of key points for subgrade construction provided by a small road roller manufacturer, intended to assist you.
1. When using a small roller for subgrade construction, it is essential to first ensure proper drainage facilities to prevent water damage.
2. For subgrade embankment construction, first establish the boundary lines, remove the topsoil to the edge of the roadway, backfill and level the excavated areas, then compact them to ensure embankment stability and prevent settlement.
3. Small road roller manufacturers remind you to carefully select subgrade fill materials to ensure soil stability and that the soil’s strength and particle size meet construction requirements.
4. During embankment construction, the steps of successive layers must be lapped and the interface between new and existing material properly bonded. On sloping surfaces, steps should be cut, and staged filling with stepped profiles should be employed, while adjacent construction layers are placed in overlapping fashion.
5. For embankments constructed with mixed fill of different soil types, the fill material should be layered according to soil characteristics and graded based on strength and permeability to prevent subgrade instability.
