The articles share some tips on how to select small road rollers
The quality of road rollers is not only relevant to construction quality and process but also strongly to the project cost budgeting.
Different brands, models, performance, prices, and quality in the market bring more options, but at the same time, it also increases the difficulty of choosing. To reduce the risk of investment and receive higher benefits, we should do reasonable procurement which according to site construction requirements. Think wiser on evaluating products.
Generally, road rollers have 2 types: Static and Vibratory. Static rollers could be divided into tandem smooth wheel roller, triple smooth wheel roller, pneumatic tired roller, and so on; Vibratory rollers could be divided into single steel wheel roller, tandem steel wheel roller bump wheel roller, etc.
Work efficiency
1) .Technical data of static and vibratory rollers:
Type | Compaction thickness | Walking speed | Rolling frequency |
Vibratory roller | 50-60 cm | 0-8km/h | 4-6 |
Static roller | 25 cm | 0-4km/h | 8-10 |
As for static roller: It performances the compactness according to its own weight, linear load, time of rolling compaction, and walk speed.
2).Construction principle
The construction principle of vibratory roller: high frequent vibration generates impact forces. Under the forces, small macadam will fill in road gaps.
As for static roller: It performances the compactness according to its own weight, linear load, time of rolling compaction, and walk speed.
3) . Assuming that a 6 km length concrete road is under construction.The work efficiency of 2 rollers is as follows:
Type | Road length | Average rolling frequency | Average walking speed | Construction time |
Vibratory roller | 6km | 5 | 4km | 7.5h |
Static roller | 6km | 9 | 2km | 27h |
It can be seen from that it saves about 72% time with vibratory rollers.
Therefore, shorter construction season regions also should choose vibratory rollers.
