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.

Slab on grade is a slab directly supported on the soil. Slab on grade is used for construction of industrial floor and rigid pavement. For construction of slab on grade, fibers mainly steel fibers are used with specified doses. Addition of the fiber in the slab on grade improved the ductility and post cracking nature of the load verses deflection curve. Area under load deflection curve is called toughness. Peak load of SFRC is higher than the plain cement concrete. Steel fibers are more appropriate to used in slab on grade that synthetic and polypropylene fiber. Non linear fracture mechanics of concrete between cracks is evaluated to understand the performance of the SFRC. Parametric study carried out to evaluate the effect of type of steel fiber, dose of steel fiber and load -deflection curve on the depth of the slab on grade. Some equations and charts are proposed for the calculation of dose of fibers based on loading criteria and minimum depth of slab on grade. Plastic method, yield line analysis and non linear fracture mechanics methods consider for analysis and design of slab on grade. Slab on grade should be sustainable to perform satisfactorily intended use and economical. To design slab on grade with minimum slab thickness and optimum dose of fiber based on serviceability criteria reflects sustainability construction approach.
