Recycling seal-coat pavements with self-cementing fly ash. Phase 2, progress report No. 1
The purpose of the proposed research is to evaluate the feasibility of recycling existing seal-coat pavements through stabilization with self-cementing fly ash. It is proposed that existing pavements can be pulverized in-place, sufficient quantities of Class C fly ash and water added, and the resulting mixture be compacted. The stabilized section could then be utilized as a base course section having greater support capacity than the original pavement section. The recycling process is intended primarily for existing pavements having up to 4 inches of asphaltic bound material underlain by a granular-base section of variable composition. The intent of the Phase II research is to establish more definitive criteria relevant to mix design and pavement thickness design for the proposed recycling process. The criteria is to be formulated through both laboratory and field tests on recycled pavements in a multistate area.
