Final answer:
The UFC for rigid/flexible pavement surveys is UFC 3-270-01, which guides maintenance and repair of asphalt and concrete pavements, typically used by civil engineers in the Department of Defense.
Step-by-step explanation:
The UFC that governs rigid/flexible pavement surveys is UFC 3-270-01, which is titled “O&M: Asphalt and Concrete Pavement Maintenance and Repair”. Pavement management systems and surveys are crucial for maintaining the integrity and safety of pavement in airfields and highways. This UFC provides guidance on how to assess the condition of both rigid and flexible pavements and outlines procedures for maintenance and repair activities. It is used not only to maintain and extend the pavement life but also to ensure cost-effective allocation of resources towards pavement maintenance and repair. The guidelines in this document are typically followed by civil engineers and professionals responsible for infrastructure maintenance within the Department of Defense.
