Final answer:
After laying the surface with a paving machine, the required work is to properly compact the material to ensure density and durability. Additional finishing touches might include applying sealants and paint for lines or textures.
Step-by-step explanation:
The only work required after the surface has been laid with the paving machine involves the compaction of the newly laid pavement materials. This is a crucial step as it significantly influences the long-term performance and durability of the pavement surface. Compaction needs to be achieved before the material cools down if dealing with asphalt, or sets if dealing with concrete.
Proper compaction ensures adequate density and material properties, providing a pavement layer that can withstand traffic loads and environmental factors. Sometimes, finishing touches may also include application of joint sealants and line painting or surface texturing for safety and navigational purposes.
