What is the main consequence of using the incorrect roller type on certain mixes?

The main consequence of using the incorrect roller type on certain mixes is damage to the pavement structure. Different types of roller equipment are designed to achieve specific compaction levels and cater to various materials. When the wrong roller is used, it may not adequately compact the asphalt or concrete, leading to inadequate density, which compromises the overall integrity of the pavement. This can manifest as surface cracking, deformation, or reduced load-bearing capacity over time.

Proper roller selection is crucial because the wrong type can also introduce imperfections. For instance, a roller that is too heavy might crush the aggregate, while a too-light roller may fail to compact the material sufficiently. Both scenarios can lead to structural weaknesses, ultimately resulting in costly repairs and maintenance.

Efficiency, higher compaction levels, and cost savings are desirable outcomes but depend heavily on using the appropriate roller type. If the roller type is incorrect, the risks associated with pavement damage overshadow any potential benefits in these other areas.
