Abstract

The disposal of industrial by-products constitutes a mounting problem of global dimensions. Among these, the disposal of fly ash is very problematic, for the increasing demand for electricity from coal burning power stations has been resulting in growing amounts of stockpiled fly ash, inevitably causing environmental problems. The use of this fly ash in road pavements provides an opportunity to use high volumes of this material, however, the ash needs to be stabilized to improve its performance when utilized in upper pavement layers. Because the principal input in mechanistic-empirical analyses is resilient modulus, the aim of this study is to investigate the effect of stabilization on resilient modulus of a Class F fly ash.
