Final answer:
Bituminous pavers offer a smoother surface, a more uniform application, and increased efficiency over motor graders, resulting in a high-quality roadway that is comfortable to drive on and requires less maintenance.
Step-by-step explanation:
When comparing the use of bituminous pavers to motor graders, some of the advantages include providing a smoother finished surface, a more uniform application of bituminous material, and increased operational efficiency. Bituminous pavers are designed to spread and compact the asphalt mixture in a continuous and efficient manner, leading to a high-quality roadway surface that can offer improved driving comfort and less maintenance over time.
On the other hand, motor graders are typically used for the initial leveling of the surface, which is not as precise for the final asphalt layer since it is not their primary function. Using bituminous pavers is therefore advantageous in achieving a superior finish for road construction.
