16. Abstract

Geotextiles, one among the different geosynthetic products, can be used for a number of functions or applications in

pavement design. The benefits of using geotextiles in pavements and other transportation applications have triggered

a proliferation of products. While this abundance of new products has led to reduction in costs, it has also made it

difficult for TxDOT personnel to choose appropriate products based on their engineering properties. Consequently,

this report provides the basis for (i) guidelines for proper use and selection of geotextiles in pavements, (ii) material

specifications for geotextiles in pavement applications, and (iii) draft construction specifications.
