Laboratory Evaluation Of Prefabricated Highway Edge Drains, Ahmed Mohamed Elsharief
JTRP Technical Reports
This study evaluated prefabricated highway edge drains to improve the existing practice and to set guidelines for their proper selection. Two primary evaluations received attention: the first was the effect of installation and in service loading on the hydraulic and strength capacities of a prefabricated highway edge drain; and the second was the performance of the geotextile filter.
A limited field evaluation of prefabricated highway drains indicated structural failure of the core and an inefficient geotextile. Based on, the field study, laboratory testing and theoretical modeling, guidelines were given for the strength and hydraulic requirements of the drain. A retention …
