Use of incinerator ash in construction of highway pavement layers may havethe potential to significantly reduce the quantity of ash that must be disposed of. However, thephysical properties of ash are not optimal for construction of normal asphalt pavement. Whendesigned and applied properly, foamed asphalt provides a way of obtaining good coating on granularmaterials made from ash and hence adequate cohesion of pavement materials. Also, foamed asphaltprovides a way of using materials with relatively high percentage of fines and moisture content.This paper briefly reviews foamed asphalt and its use, production of aggregate from incinerator ash,and describes design, construction, and evaluation of a parking lot pavement using foamedasphalt-treated ash. Based on the results obtained from mix designs it was recommended that 2 30650784mebe added to a mix with 100ash (at optimum moisture content), and that 1 16me be used when 75ashis combined with 25recycled concrete-the recycled concrete be
