Abstract:

This paper presents the results of a field investigation and laboratory testing program to evaluate the properties of two different polypropylene, thermally-bonded nonwoven geotextiles exhumed from seven existing unpaved road structures. The results of the field investigation and test program are used to assess the construction survivability and long-term durability characteristics of the two materials. Measured geotextile strengths after one to twelve years of burial range from 50 to 90% of their initial values. The conclusion is reached that almost all of the strength loss experienced by the geotextiles is due to mechanical damage that occurred during construction.
