“…Typical values for the permeability of gravel materials are given for loosely compacted specimens; however, according to Lambe and Whitman [35] the permeability is minimum at maximum compaction, which means that the values in Table 5 are less than most table values. We believe, the permeability of 0-32 mm sub-base gravel was larger than the permeability of 0-8 mm sub-base gravel because the tortuosity of the pore system is less for 0-32 mm sub-base gravel, as discussed in Lund et al [20].…”

Pearl-Chain Bridge technology is a recently developed prefabricated arch solution for road and railway bridges allowing faster, more environmentally friendly, and cheaper bridge construction. This study compared the strength and durability properties of three different types of fill material to find the most optimal fill for Pearl-Chain Bridges. Sub-base gravel, cement-stabilized gravel, and pervious concrete were tested with respect to compressive strength, stiffness, splitting tensile strength, permeability, freezethaw durability, and shrinkage. This paper summarizes the advantages and disadvantages of implementing the different types of fill material in arch bridges, particularly in Pearl-Chain Bridges.

“…The compaction degree, defined as the ratio between the actual dry density of the specimen and the optimal dry density determined from laboratory tests, was above 97% for all specimens. A more detailed description of the preparation of the specimens is found in Lund et al [20].…”
