Where is the handbrake of the road roller located?

[MacColeman]

The handbrake of the road roller is located above the rear wheels. Functions of road rollers: In highway, railway, airport, hydraulic engineering, and construction projects, road rollers are mainly used for compacting roadbeds, pavements, embankments, cofferdams, and building foundations. Significance of compaction: Through methods such as rolling and impact, external forces overcome the friction between particles of soil, gravel, and asphalt mixtures, bringing them closer together and squeezing out water and air. This causes larger particles to rearrange, reducing the gaps between them, while smaller particles fill the gaps between larger ones, expelling water and air from the voids. Under external forces, particles may break, leading to further filling. This increases the friction and cohesion between material particles, resulting in denser compacted materials.
