The use of waste materials in highway construction in the UnitedStates and applications of selected waste materials, including waste tires, waste glass, reclaimed paving materials, slags and ashes, building rubble, and sewage sludge are discussed. An evaluation based on technical, environmental, and economic factors has indicated that reclaimed paving materials, coal fly ash, blast furnace slag, bottom ash, boiler slag, steel slag, and rubber tires have significant potential to replace conventional materials for various applicationsin highway construction and should be projected for future construction. Specific applications of the waste products and the potential problems associated with their usage in highway operations, which must be addressed before their extensive use, are included
