Comparison Between Second-Hand XCMG Road Rollers and Road Compactors

On road construction sites, numerous types of construction machinery are used, among which road rollers and road compactors are often confused. However, there are key differences between the two. As an industry expert with 23 years of experience in the second-hand construction machinery field, Hefei Gangjia Construction Machinery Co., Ltd., leveraging over 8,000 equipment transactions, offers a detailed analysis of the fundamental differences between these two core road equipment categories.

Working Principle Comparison

The fundamental difference between a second hand road roller and a road compactor lies in their working principles. Road rollers are primarily divided into static and vibration types:

• Static Road Rollers: For example, the classic XCMG light-wheel series, which relies on mechanical weight to apply continuous static pressure to the ground. Through repeated rolling with steel wheels or rubber wheels, the surface material undergoes permanent deformation and compaction. These machines are suitable for compaction of asphalt layers and can form smooth, even surfaces.
• Vibratory Road Rollers: These machines add vibratory force on top of their own weight. The high-frequency vibrations help to reorganize the material particles, making them ideal for non-cohesive soil bases such as sand and gravel. Their impact depth can reach up to 0.8 meters.

In comparison, road compactors (such as impact compaction equipment) represent a disruptive technology:

• They use non-circular polygonal rollers, which accumulate significant kinetic energy due to the difference in center of gravity when the towing vehicle moves.
• When the roller’s corners impact the ground, they release a concentrated impact force of 250-300 tons, creating a pressure of over 1500 kPa.
• This “compaction + rolling + kneading” compound effect allows the shockwave to penetrate over 5 meters deep, far exceeding the 0.8-meter impact depth of vibratory rollers.

Application Scenario Comparison

Road Rollers: Precision in Action

• Tire Rollers: With flexible rubber tires, these rollers achieve a “kneading effect” during asphalt compaction, preventing aggregate breakage. They are essential for re-compaction of highway surface layers.
• Sheep’s Foot Rollers: With a block structure that can break clay lumps, these are particularly suitable for compaction of cohesive soils with moisture content within ±2%.
• Vibratory Steel Wheel Rollers: These are highly efficient in gravel roadbed construction, but material moisture content must be carefully controlled to avoid springing soil.

Compactors: Heavy-Duty Tools

• Impact Compactors: These are highly adaptable to moisture content and are irreplaceable in high embankment foundations and subgrade improvement projects.
• They can directly crush old concrete pavements and compact the debris into the base, eliminating the need for excavation, which reduces the construction period by more than 30%.
• In specialized fields like surface coal mine compaction and deep reinforcement of airport runways, these machines have a distinct advantage.

Second-Hand Road Roller Market Value

• Price Advantage: The cost of purchasing a second-hand XCMG road roller is 30-50% lower than that of a new machine, shortening the investment recovery period to 12-18 months.
• Value Retention: A re-manufactured 20-ton vibratory road roller from XCMG can have a core vibration wheel life of over 15,000 hours.
