Which type of roller is ideal for pavements placed over uneven surfaces?

Pneumatic rollers are particularly well-suited for pavements placed over uneven surfaces due to their design and function. These rollers have tires that can conform to irregularities in the ground. This adaptability helps them achieve better compaction in areas with variable elevations and fills. The rubber tires create a kneading action, allowing the roller to effectively compact the asphalt material without causing harm to the surface, which is especially important when working with uneven substrates.

In addition, pneumatic rollers provide uniform pressure distribution, leading to less segregation and better density of the hot mix asphalt. The flexibility in handling surface irregularities makes them an excellent choice for projects where the underlying base may not be perfectly level.

While static rollers are effective for straightforward compaction tasks and vibratory rollers are useful for dense and cohesive materials, pneumatic rollers specifically excel in scenarios involving uneven surfaces.
