Which items are included in the steps to a good quality pavement?

• A. Pavement design (Thickness, mix type); Mixture design (Material selection, binder %); Subgrade preparation; Base construction; Asphalt concrete production; placement and compaction; Acceptance and Payment
• B. Surveying and site clearing only
• C. Final acceptance testing only
• D. Payment scheduling and contract closure

Answer: (A)

The main idea is that a good quality pavement comes from controlling every step from design through construction to acceptance. This includes designing with the right thickness and mix type, performing a mixture design to select materials and binder content, preparing the subgrade, constructing the base correctly, producing the asphalt mix to specification, placing and compacting it to achieve proper density and compaction, and finally conducting acceptance testing (to verify the work meets standards) and handling payment. Each stage ensures the pavement will perform as intended; skipping or rushing any part can undermine durability and performance. The other options omit essential stages like design, subgrade preparation, or compaction, and thus don’t address the full set of steps that contribute to pavement quality.
