| Sumario: | ABSTRACT: This doctoral thesis evaluated the potential of an open-cell phenolic foam as a water barrier system for Permeable Pavement Systems (PPS). OASIS® Floral Foam as a highly absorbing material was evaluated for its ability to enhance or even replace conventional geotextiles in PPS. The effect on the hydraulic performance and compaction of pavements resulting from the inclusion of such water barrier was evaluated in laboratory settings. Both OASIS and Inbitex geotextile found to improve the water retention and attenuation of PPS in comparison to unlined “conventional” PPS systems. PPS with OASIS found to respond better under low intensity consecutive rain events retaining and attenuating larger cumulative water volume than Inbitex geotextile PPS, and performed better in every scenario before reaching its saturation point. The influence of the phenolic foam on the structural integrity of the pavement and the effect of compaction on its water holding capacity were investigated against various placement configurations, placement depths and sizes. It was found that placement of OASIS as an infill in the sub-base aggregate does not result to significant pavement compression and it was identified that the placement configuration plays a role on the water retention capability of pavements, suggesting that an OASIS infill placement can be a feasible option for PPS. |
