When it comes to the project that you’re working on, there are several factors that determine the roller that you’ll use for your job. Simply put, there are cylindrical rollers, grid rollers, pneumatic rollers, sheepsfoot rollers and even the vibratory wheeled rollers available for compacting your soil. Our article features the popular rollers which can be found within Pakistan.
First, we’ll look at the cylindrical roller. This particular road roller for sale in Pakistan is a bit of a classic and it can lightly roll concrete, iron or even stone. And it is used by either hand or animal and comes in a variety of sizes. However, the ground pressure which is generated by this particular machine is roughly 7kg/cm2.
Second on our list is the sheepsfoot roller. This particular machine is known widely by its name since its rolling drum is made up of several rectangular or even round protrusions on it. However, they are available in a series of different drum widths as well as different diameters and the feet can even have varied shapes. As such, these rollers typically cover up to 12% of their work area and can compact up to a whopping 5cm more than the overall length of a single foot.
The sheepsfoot roller has been known to be used for compacting highly cohesive soils like that of silty clays and even heavy clays. However, they cannot be used where there is sandy soils since they are non-effective. And if you’re interested in increasing the drum’s weight, you can simply add some damp sand or water.
Third on our list is the pneumatic wheeled roller. This particular machine is known for having up to six tyres which are closely spaced as they transport a pretty heavy wagon. When it comes to the compaction applied, it is typically based on either the contact area or the tyre pressure. In some cases, the pressure in the tyre is roughly 7kg and this ensures that up to 80% of the area is covered.
However, this particular roller also produces a weight between either 6 or 10 tonnes and this can easily be increased up to 25 tonnes if you were to ballast with a steel section. Additionally, this roller is used for compacting pavements that are made from bitumen, loose soil and even some course-based materials. And it can even be used for the purpose of compacting closely graded sands and even finer soils.
Fourth on our list is the vibratory roller, also called the driving road roller, you can find from this site: https://aidomachinery.pk/driving-road-roller-for-sale-in-pakistan/. This state-of-the-art roller has been created with either one or two smooth surface wheels that come in varied diameters. This machine is also self-propelled and can weigh a whopping 6 tonnes.
