IMPROVING STORMWATER QUALITY USING A NOVEL PERMEABLE PAVEMENT BASE MATERIAL
Permeable pavements provide new opportunities to unseal transportation infrastructure and to improve the urban climate. Because of limited durability, conventional materials for permeable pavements are used only selectively in urban areas. Thus, the development of innovative infrastructure materials for durable permeable pavements are required. A full substitution of bitumen by an innovative synthetic binder was restrictively applied within road-construction engineering so far, although the performance potential as well as the characteristic versatility are very high. Particularly, regarding the considerate exploitation of raw materials, polyurethane PU can be used as an alternative to bitumen. In this context it could be identified that polyurethane, for which production is mainly based on renewable raw materials, is appropriate to replace conventional bitumen. The created pavement material PU-asphalt presents high porosity with high material strength and low sensitivity of temperature at once.
Permeable Pavements: New Technique for Construction of Road Pavements in India
Ikenna Uju , University of Central Florida. This thesis presents a study on the strength properties of the different pervious pavement systems installed at the Stormwater Management Academy field laboratory at University of Central Florida UCF , Orlando. The strength tests were performed both in the laboratory and in the field.
Permeable pavement is utilised in order to alleviate flooding in towns, cities and other urban areas, but it is prone to clogging, has relatively low strength and requires regular maintenance. We have developed a novel permeable pavement with low tortuosity pore structure that can be cast on-site that is not only resistant to clogging, but also has high permeability and strength. This high strength clogging resistant permeable pavement CRP was prepared by introducing straight pore channels of varying size and number into self-compacting mortar.
