Product Information
- Name : Roller
- SKU : BLT-119
- Category : road-rollers
Rollers are road compaction machinery that rely on their own weight and vibration forces to compact roadbeds and asphalt pavements, squeezing sand, gravel, and asphalt mixtures into a dense state to enhance road hardness and stability. The three main types—single-drum, double-drum, and pneumatic-tired rollers—feature compact structures and high compaction force, making them essential equipment for the final stages of road construction.

Working Principle
The engine drives the machine forward, with the steel drum rolling tightly against the ground. Standard static pressure models rely on the machine's own weight to achieve basic compaction. In vibratory rollers, the high-speed rotation of an internal eccentric shaft generates high-frequency excitation force, which, combined with the machine's own weight, causes soil and pavement material particles to interlock tightly, eliminating voids. This ensures that the roadbed and pavement structure remain firm, resistant to settlement and cracking.
Application Fields
1. Highway and Municipal Engineering: Compaction of asphalt layers on main roads and rural roads, as well as layered compaction of roadbeds.
2. Infrastructure Sites: Compaction operations for parking lots, factory areas, and building backfill.
3. Water Conservancy and Dams: Layered compaction and reinforcement of earthwork on river embankments and dam bodies.
4. Small-Scale Projects: Compaction and leveling of backfill in community roads, sidewalks, and trenches.
