Self Fertilising Geotextiles for Use in Pervious Pavements: A Review of Progress and Further Developments: Contrôle à la source; Assainissement routier; Source control; Highway stormwater management

Geotextiles incorporating inorganic nutrients (particularly phosphorous) to enhance the growth of oil degrading microoganisms when geotextiles are used in pervious pavement applications have been shown to be effective in the past. However the cost and manufacturing difficulties have been a barrier to their use. A polypropylene random mat geotextile incorporating an alternative polymer additive as a source of phosphorous has been investigated as a potential self-fertilizing geotextile. Initial
experiments are reported which investigate with nutrient leach rates, and both small scale, short term, and medium scale, longer term tests to determine the capability of the textile to support
biodegradation.
