Soil compaction is done by Rollers. Many models of these rollers can be found in the market. Depending on the soil type and conditions, we chose rollers to work on them. For example, for soils with high % of clay we mainly use Sheepsfoot rollers and for granular soils we use vibrating rollers. The selection of roller depends on other factors like speed, desired compaction etc
The table below shows the average speeds, mi/h (km/h) under normal conditions:
| Type | mi/h | km/h |
| Grid rollers | 12 | 19.3 |
| Sheepsfoot rollers | 3 | 4.8 |
| Tamping rollers | 10 | 16.1 |
| Pneumatic rollers | 8 | 12.8 |
To calculate compaction production use the following formula
yd3/h (m3/h) = 16WSLFE/P
where
W = width of roller, ft (m)
P = number of passes
S = roller speed, mi/h (km / h)
L = lift thickness, in (mm)
F = ratio of pay yd3 ( m3) to loose yd3 ( m3)
E = efficiency factor for excellent =0.90, average=0.80, poor= 0.75

I want know types of road roller & How area compacted one roller per hour
Road roller Images also i want know
i want to know the types of compacting equipment and images
I like to know the different types of compaction rollers available in the industry and how they look like.
I like to know the different types of compaction rollers available in the industry and how they look like.
i like to know its cost and its rent per hour…for only purpose of assignment
what is the ratio of pay, explain futher.
We are exploring the possiablity to buy heavy soil compection equipemenst for the construction of dam. pls sugesst the tpye of equipemenst for the work with complete buyibng procedures.
Regards,
what does the “ratio of pay yd” mean in the formula where: F = ratio of pay yd3 ( m3) to loose yd3 ( m3)
