To understand the complexities of driveway construction and maintenance, research has been conducted on the structural condition of reinforced concrete driveways, considering factors like design, construction, and potential environmental influences.

Structural Condition Assessment of Reinforced Concrete Driveways

The reinforced concrete structure of a driveway, constructed in the 1980s, is under examination. This single-story structure, approximately 66.00 m in length, is designed as a reinforced concrete skeletal system comprising 7 frames with cantilevers, spaced at 9.00 m intervals. Specifically, 3 frames in the horizontal section and 4 frames in the sloping section are utilized. The main beams of the driveway frames feature a rectangular cross-section and are supported by columns founded on spread footings, forming a monolithic structure. Prefabricated reinforced concrete hollow floor slabs were installed in the central portion, while the outer sections employed hollow clay slab blocks (Ackerman type). At the time of the investigation, the uppermost layers of the driveway consisted of a surface waterproofing layer and a concrete slab approximately 10 cm thick, laid on a 1 cm sand bed. Notably, an internal waterproofing layer, as per the original design, was absent. This paper details the methodology for determining the current technical condition of the reinforced concrete driveway structure, with particular emphasis on the object’s design and construction, its operational history (including considerations of concrete durability under potential marine environmental influences). Static and strength analyses were conducted, supported by concrete and reinforcement testing, to evaluate the conditions for continued serviceability and to develop rehabilitation strategies.
