Accelerated Slab Replacement Using Temporary Precast Panels and Self-Consolidating Concrete. Summary.

摘要

Researchers at Florida State University demonstrated the feasibility of using precast reinforced concrete panels to temporarily fill slab removal pits. The precast slabs can be driven on so traffic lanes can be open during the day, and new slab casting can be postponed, allowing for slabs to be removed during the entire work period. The researchers also developed a self-consolidating concrete (SCC) that speeds up slab replacement by eliminating the need for compaction of the concrete. Use of SCC reduces needs and costs of both labor and equipment.
