USE OF WASTE MATERIALS
IN PAVEMENT CONSTRUCTION
1. Purpose. This Engineer Technical Letter (ETL) provides general information on the
types and uses of waste materials in pavement construction, including environmental
2. Applicability. This ETL applies to all HQUSACE elements and USACE commands
having military construction responsibility.
3. References. Appendix A contains a list of referenced and related publications.
4. Distribution. Approved for public release; distribution is unlimited.
a. The safe disposal of waste materials is an increasingly economic and
environmental concern in the United States and around the world. When applicable, the
inclusion of waste materials into pavement construction materials is a desirable goal.
However, due to the importance of roads to commerce and personal mobility, the
pavement structure should not become simply a waste disposal area. Waste materials that
are included in the construction of the pavement must meet certain engineering,
environmental, and economic criteria. The waste material must not have an unacceptable
adverse effect on the performance of the pavement. The waste material should not have
unacceptable health concerns to workers or users either during construction or while in
use. The waste material should be properly contained within the pavement structure
thereby posing no threat to the environment. The use of waste materials must be
economically sound both initially and over the life of the pavement.
b. This ETL provides general information on the types, uses, and environmental
considerations of waste materials in pavement construction. The information provided is
for the use of waste materials in various applications of pavement construction.
6. Action Taken. Pending publication of permanent guidance, Appendix B of this ETL
will be used to assist HQUSACE, major subordinate commands, district offices, and
FOA in the design and construction of pavements using waste materials.
