The road roller is a common construction machine. It can deform and compact the rolled layer by its mechanical gravity. There are two types of rollers: steel wheel and tire. There are many factors to consider when it comes to choosing the right type of roller for your needs. Which one is right for you? The tire-type road roller is a new road roller developed based on the original drum roller. It has the advantages of good compaction performance, flexible steering and convenient operation. The following will help you choose the road roller that suits you!

A drum roller is a mechanical device that uses gravity and vibration to compact various construction and road materials. Asphalt concrete materials are widely used.
The tire roller can adjust the ground contact pressure by increasing or decreasing the counterweight and tire air pressure to adapt to the compaction of different materials. The rollers use pneumatic tires, and this type of road roller adopts a hydraulic, hydraulic or mechanical transmission system, single-shaft or all-shaft drive. The compaction process has a kneading effect, is uniform and dense, and has good manoeuvrability and fast running speed. Because of this, it is often used for the compaction of engineering cushions such as roads and airports.
(1) Drum rollers, the roller structures of the drum rollers include smooth rollers, grooved rollers and sheep foot rollers. Light grinding has a wide range of applications, mainly for the compaction of urban road surfaces. According to the axle layout, there are single-axle, single-wheel, double-axle, double-wheel, double-axle, three-wheel and three-axle three-wheel. Machinery and equipment use gravity and vibration to compact various construction and road construction materials. In highway construction, the shaker is suitable for compacting various non-cohesive soil layers, sand and gravel, sand and gravel mixture and various asphalt concrete raw materials, so it is widely used.
(2) Tire roller, a tire roller, is a machine that uses many pneumatic tires to compact urban roads. The machine drum adopts pneumatic tires, usually 3 to 5 front wheels and 4 to 6 rear wheels. If you change the inflation pressure, you can change the ground pressure, and the pressure adjustment range is 0.11 to 1.05 MPa.
(1) The steel-wheeled road roller adopts an articulated frame, hydraulic walking, vibration, and a fully hydraulic steering system. It has two vibration frequencies and two levels of amplitude, which can satisfy the compaction of layers of different thicknesses and various raw materials…
(2) The tire-type road roller can adjust the grounding specific pressure according to the increase or decrease of the counterweight and the tire air pressure, to satisfy the compaction of different raw materials. The front-wheel adopts a mechanical swing type suspension device with a service brake, parking brake, reliable performance, good sound insulation and vibration reduction effect.
A tire roller is a compaction machine that relies on its weight to increase the density of the working medium through the static compaction of the plying material by specially-made tires. In addition to the vertical compaction force, it also has the horizontal compaction force, which has the effect of compaction along the running direction of the machine and has the effect of compaction along the lateral direction of the machine. Because the compaction force can act on the material particles in all directions, combined with a “kneading effect” produced by the elasticity of the tire, it produces an excellent compaction effect so that the maximum density can be obtained. If the asphalt mixture is compacted with a smooth drum roller, the contact line of the drum will form a “bridge” phenomenon between the large particles of the asphalt mixture—even compaction. In contrast, the rubber tire flexes and compacts along these contours, resulting in a better-compacted surface and better compaction. At the same time, due to the tire’s flexibility, the asphalt mixture is not pushed in front of it. Still, the initial contact point is covered with the mixture, giving the material a large vertical force, which will avoid the frequent occurrence of smooth drum rollers—crack phenomenon. In addition, the tire roller also has the characteristics of increasing or decreasing the counterweight and changing the tire inflation pressure, which is more conducive to the compaction of various materials. Based on the above characteristics, tire rollers are widely used in the compaction of the base layer, sub-base layer, fill, and asphalt surface layer of various materials; especially in the compaction of asphalt pavement, the unique flexible compaction function of tire rollers It is irreplaceable by other compaction equipment, so it has become the main machine for recompression of asphalt mixture. It is also ideal compaction equipment for the construction of high-grade highways, airports, ports, dams and industrial construction sites.
A major feature of pneumatic tires is that the air pressure in the tire can be changed to limit the maximum compressive stress on the surface of the layup compacted material, thereby improving the compaction effect. Under the same gravity load, the maximum compressive stress of the pneumatic tire is smaller than that of the smooth steel wheel, so the bearing capacity of the surface of the ply material is also smaller so that the lower layer material can be better compacted. Therefore, the tire roller can improve its compaction performance and expand its range of use by changing the pneumatic tire’s load or adjusting the tire’s inflation pressure. In contrast, the drum roller can only change the line load by changing the roller’s bag. When the pneumatic tire is rolled many times, the radial deformation of the tire increases, while the deformation of the ply decreases due to its increased strength. The reduction of the ply deformation will cause the tire contact area to shrink, thereby increasing the compressive contact stress, and the pressure at the end of compaction is 1.5-2 times that of the first rolling. At the same time, the rolling resistance of pneumatic tires also decreases with the increase of ply strength, which can significantly improve the rolling effect and compaction quality. It can be seen that a tire roller using pneumatic tires as a working device can roll various types of materials, including viscous and non-viscous materials.
First, check tire pressure frequently. If the tire pressure is increased by 25%, the tire life will be reduced by 15%-20%; if the air pressure is decreased by 25%, the life will be shortened by about 30%. Driving under abnormal tire pressure will reduce the service life of the tire and increase the fuel consumption and even cause a tire blowout.
Second, clean up the debris in the carcass in time. Some sundries will be embedded in the tire surface when the car is running, such as nails, stones, glass, iron pieces, etc. If it is not cleaned up in time, the sundries will be inserted into the tire step by step, which will reduce the strength of the cord and cause delamination or even explosion. Fetal.
Third, the load should not be too large. If the car is overloaded, the tires will be overheated, the rubber will be aged, and the life of the tires will be shortened. Tests show that if the tire is overloaded by 10%-12%, the tire’s mileage will decrease by 20%-40%.
Fourth, when the vehicle is parked, it is also necessary to protect the tires and avoid parking them on the road surface with thick, sharp or sharp obstacles. In addition, it should be avoided as much as possible to park with petroleum products, acid substances and other materials that affect the deterioration of the rubber.
Fifth, check the tire tread, check whether the tire tread is punctured and whether there are stones stuck between the two wheels. Remove the stones embedded in the tire and, find a small hole on the tread, fill it with raw rubber to prevent sand and mud from invading the cord layer and causing voids.

Road roller Truck (sometimes called a roller-compactor, or just roller) is a compactor-type engineering vehicle used to compact soil, gravel, concrete, or asphalt in the construction of roads and foundations. Similar rollers are used also at landfills or in agriculture. Road roller Truck are frequently referred to as steamrollers, regardless of their method of propulsion.
This is a prosaic style of a roller, which is lightweight and may be handled by the blue-collar or by domiciliary creatures. It is usually assembled by iron, concrete, or stone.It generally estimates around 1 m in diameter and 1.5 m long & generated ground pressure is around 7kg/cm2.
They encompass a network of grid-like steel bars which can even be ballasted with concrete blocks or steel adjuncts. These sorts of rollers are generally towed or pulled behind a tractor at speeds amidst 5 & 24 km/h
The grid design churns out a high contact pressure with bijou kneading venture on compaction job. They are most fitted on well-graded, boorish soils, disintegrated rocks, and for sub-grade and sub-base road constructions.
Pneumatic rollers are colossal, ride-on roller with series of rubber tires at the front or at the occiput part. The rubber tyre supplies 80% coverage area & invariable pressure disseminated throughout the breadth of the tires.
They are typically utilized for highways, streets, dams and might aid to shine a project, but additionally are extraordinary for cold-laid bituminous veneers & veneers of loose soil.The pneumatic roller has the ductility to exercise contact pressure ranges from 500 – 700 Kpa or 7k g/cm2. The weight of the roller is 6-10 tonnes which are surged to 25 tonnes by ballasting.
The utmost bulk is acquired by 8 passes & the optimum speed of the roller retains somewhere between 6-24 km/h.
Sheepsfoot rollers are occasionally called padfoot or tamping rollers. They have innumerable rectangular-shaped lugs or “feet.” They’re adept in compacting soil & silty clay during a construction job.

The sheepsfoot drum’s weight might be surged by ballasting (with water, damp sand, or mounting steel sections). The area of each & every portion can range from 30 to 80 cm2. About 10-20 passes are required to provide thorough coverage.
Coverage Area is about 8-12 % because of boots on drums. Contact Pressure ranges from - Kpa. The soupiness of compacting layer is about 5 cm extra the length of every foot.
The factors that govern the quantity of compaction of soil are given subsequently:-
There are 2 kinds of smooth wheeled rollers: single & double drum roller. They are again noted as static rollers. Smooth wheel roller and vibratory rollers are basically alike. Both have identical features. There’s just one point of distinction, i.e., vibratory equipment. Smooth wheel roller has no vibrator attached and is best suited to rolling of fragile aggregates and in compacting asphalt pavements.
The tandem, or double drum roller, has one steel drum at the front and another at the rear. As soon as the two drums move, the Road roller Truck moves. These Road roller Truck are adept in compacting silty or sandy or flat soil with gradual surfaces like asphalt but are not nominated for any distinctive job.
According to the number of wheels on the rear, it is of subsequent two types:
Tandem rollers (having one wheel at the rear and one wheel in front)
Three-wheeled rollers (having two wheels at the rear and one in front)
Traveling across Quang Binh to stunning cinematic locations .The weight of the tandem roller varies from 2 to 8 tonnes, and the two-wheeled roller ranges from 8 to 10 tonnes.
They possess a steel drum at the front & 2 special wheels at the rear. Single drum rollers can toil at tighter spaces due to their bijou size. They are adept at creating foundations for buildings and paving highways or sidewalks.
The ground coverage is 100%. The pondage of the roller is surged by filling the within space of the drum with water or wet sand. This process is named ballasting. The ground pressure exercised by tandem rollers is about 10 to 17 kg/cm2.
The optimum working speed has been found to be 3 to 6 km/h, and about eight passes are ample for compacting 20 cm layer. Smooth wheel rollers are most fitted for blending stone soling, gravel, sand, hardcore, ballast & surface dressings. The paramount grade a road roller can climb is 1 in 5.
Vibratory rollers are nearly indistinguishable from smoothing wheel rollers aside from one major distinction: i.e., the vibrating component. Since soil, asphalt, and concrete have natural bare spaces, they will cause a vandalization to the structure of the building.
Employing a vibratory roller retains the building’s structural integrity. This style of the roller is usually fitted with 1 or 2 smooth surfaced steel wheels 0.9 m to 1.5 m in diameter and 1.2 m to 1.8 m wide.
Self-propelled vibratory rollers are now obtainable pounding from 4 to 6 tonnes. Vibrations are generally generated by the swiveling of an eccentric crankshaft present within it.
Vibratory rollers are utilized for compacting granular base courses. It’s frequently utilized for asphaltic concrete jobs. They have higher outputs and improved performance juxtaposed to other rollers but also generally come at a lofty cost.
