Abstract
Successful uses of pozzolanic fly ash for modification of a highly plastic clay, and of natural and stabilized fly ashes to effect economy in road construction, are described. Three fly ashes collected in dry, moist, and sludge states were investigated in detail for modification of a highly plastic clay. Laboratory investigations were conducted to determine suitability of natural fly ash for structural fill, and lime and cement stabilized fly ashes for base course construction. Field trial sections were constructed and performance tests made to evaluate technical and economic feasibility. Laboratory and performance data on trial sections indicate that: (1) It is possible to modify a highly plastic clay with a pozzolanic fly ash to provide stable subgrades; (2) structural fills of compacted pozzolanic fly ashes gain strength with time and are lighter and stronger than clay or sand fills; and (3) base courses of cement stabilized fly ashes can be constructed with available equipment.
