Abstract:
In restoring failed pavements, the most economical and effective solution may be to attack the problem deep within the pavement, rather than at the surface, by recycling the pavement into a strong new base. Highway projects in Florida, Louisiana, and Nevada illustrate in-place recycling of bituminous materials and granular bases by pulverizing, mixing with cement and water, and compacting into new soil-cement bases. Airport projects in Georgia and Oklahoma illustrate crushing of old concrete for use in cement-treated bases for concrete pavement. Aggregates are conserved and haul costs reduced.
