Technical and Economic Criteria to Select Pavement Surfaces of Port Handling Plants

Abstract

A port is an intermodal system in which many logistics activities requiring properly constructed areas occur. The large extension of these areas poses a major problem in choosing materials with technical and economic implications. Choice and design of pavements are directly related to the port handling systems and procedures for the disposal of the cargo units. The paper presents the design and verification procedures for three equivalent pavements for a handling pavement in an Italian medium-sized port trafficked by reach stackers moving containers. An asphalt pavement, a concrete pavement, and a concrete block pavement have been considered during the 20-year service life. Empirical and analytical methods have been adopted to design and verify the pavements. The structures have been examined in terms of economic concerns during the overall service life, considering both construction and maintenance costs, in order to determine the most cost-effective option. The results demonstrate the inappropriateness of asphalt pavement, in the examined case, from a construction costs point of view. Furthermore, the overall discounted costs show an inversion of convenience between block concrete pavement and cast in situ concrete: the latter is the cheaper solution. The proposed methodology can balance often conflicting objectives in matters of durability and funds management, providing answers to a complex topic.

Jointed Plain Concrete Pavements in Airports: Structural–Economic Evaluation and Proposal for a Catalogue

“…Although not modeled in FAARFIELD 1.42 [18], a geosynthetic sheet underlay was provided to avoid contamination of the subbase layers with fine material of the subgrade [18]. Finally, the results from FAARFIELD were verified using the Westergaard theory [20]: the maximum tensile stresses at the bottom of the slab for a load at the interior and at the edge of slab or at the top of the slab for a load at the corner were compared to MOR [41]. Finally, construction costs of each catalogued pavement were calculated using national price lists [42], regional price lists [43,44] and price lists provided by experience of the 8th Gruppo Genio Campale.…”

Deep Convolutional Neural Networks for Pavement Crack Detection using an Inexpensive Global Shutter RGB-D Sensor and ARM-Based Single-Board Computer

“…Statistics from America's Infrastructure Report Card published by the American Society of Civil Engineers (ASCE) (1) show that U.S. highways and roads are in poor condition from aging, environmental conditions, and traffic overload. A pavement crack is a critical failure of a pavement structure and presents a potential threat to transportation systems (2)(3)(4)(5)(6)(7). Pavement cracks are the most significant type of pavement distress that has been studied for years because of the complicated pavement crack patterns (8).…”
