Recycling seal-coat pavements with self-cementing fly ash. Phase 2, final report
The study evaluated the feasibility of recycling existing chip-seal pavements through stabilization with self-cementing fly ash. It was proposed that an existing pavement could be pulverized in place, sufficient quantities of Class C fly ash added, and the resulting mixture be compacted, providing a stabilized base having greater support capacity than the original pavement section. The Phase II program expanded the Phase I laboratory evaluation of stabilized, recycled material, with the focus of the testing being directed at three field projects. The field test sections were selected in regions having different sources of Class C fly ash; the three sources selected were conventional fossil fuel plants using subbituminous, low sulfur coal. The amount of gravel and asphaltic bound particles in the recycled material influenced the degree of stabilization achieved but to a lesser degree than the condition and amount of fines.
