A walk-behind road compactor is used for compacting surfaces like asphalt, dirt, and concrete. They are often used on small projects, as they offer high compaction efficiency.Walk-behind rollers or trench rollers are perfect compactors for narrow work areas that need preparation, such as pavement, shoulders and sidewalks. When equipped with a smooth drum, these rollers compact granular soil such as gravel or sand.The roller is an agricultural tool used for flattening land or breaking up large clumps of soil, especially after ploughing or disc harrowing. Typically, rollers are pulled by tractors or, prior to mechanisation, a team of animals such as horses or oxen.

Basic components of rollers include a diesel engine, a canopy to shield the operator, drums—which may be either vibratory smooth drums or static smooth drums—tires, a compaction metre to gauge the degree of compaction, and a water system. The construction industry is known for its use of road rollers.A construction roller is also known as a road roller, compaction roller, or steam roller. Although these machines are not powered by steam anymore, they used to be and in some cases, the name stuck.The world's first motorised road roller, produced by HAMM, was clearly superior to the traditional steamrollers, and developed into the first big success. Alois Hamm develops the world's first all-wheel-powered and all-wheel-steered tandem roller, the technology of which was still first-class 20 years later.

Walk-behind vibratory rollers are designed for the compaction of all sorts of soils as well as for the compaction of asphalt. Modern machines feature an optimal combination of centrifugal force, vibration frequency and static weight, resulting in excellent compaction effect.Walk-behind rollers or trench rollers are perfect compactors for narrow work areas that need preparation, such as pavement, shoulders and sidewalks. When equipped with a smooth drum, these rollers compact granular soil such as gravel or sand.Rollers are most often used for road construction or for creating compact foundations for large areas although they can also be used in areas as diverse as on landfill sites or agricultural projects. The primary use for rollers is to crush, knead or vibrate loose materials by applying direct pressure.

A road roller (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.The roller is an agricultural tool used for flattening land or breaking up large clumps of soil, especially after ploughing or disc harrowing. Typically, rollers are pulled by tractors or, prior to mechanisation, a team of animals such as horses or oxen.Grid rollers models have a cylindrical heavy steel surface comprising a network of steel bars that form a grid with square-shaped holes. It is common for the roller to be ballasted with concrete blocks. This type of roller is generally a towed unit and provides high contact pressure but minimal kneading action.
