GEOSYNTHETIC PREFABRICATED DRAINS BEHAVIOR DURING A THUNDER RAINFALL IN EXPERIMENTAL LASALLE MUNICIPALITY ROADWAY

This paper presents an overall discussion on water behavior and the analysis of edge drain response to the heavy rainfall, in the experimental roadway in LaSalle Municipality in Quebec, Canada. Eight (8) experimental road sections, equipped with different types of edge drains were constructed in 1995. One section was not equipped with drain, and was monitored as a reference section. Each section was equipped with various monitoring instruments. The project was developed in collaboration between SAGEOS Geosynthetics Technology Centre, and three Canadian governing levels (Federal - Canada, Provincial - Quebec, and Municipal - LaSalle Municipality) under the 'Canada-Quebec Infrastructures Program (94)'. It was found that edge drains are an excellent means to stop water entry in the road foundation, by cutting the natural, preferential water flow paths. Drain response to rainfall was found to be rapid, and flow rates up to two liters per minute per linear meter of drain were recorded.
