  • Abstract:
    This study examines the laboratory and field performance of two alternative materials used for the modification of unstable (CBR<6) subgrade soils. Modification is temporarily enhancing subgrade

    stability to improve the constructability of successive pavement layers. The alternative materials included a by-product hydrated lime (BHL) and a Class C fly ash (CCFA) meeting the requirements of

    AASHTO M 295. Three experimental projects were constructed incorporating these materials with a variety of soil types. The performance of sections treated with these materials was compared to that of control sections treated with a high calcium lime kiln dust (LKD) or dense graded aggregate, depending on site conditions. Information presented in this study includes laboratory background and

    mix design data, construction procedure evaluation, bearing value and subgrade rut depth data, pavement performance data, and recommended mix design procedures and specifications. The results indicate that BHL and CCFA are acceptable materials for subgrade modification.
