ABSTRACT:
Joint spaces within structural concrete bodies are filled with semi-rigid fillers to avoid adjacent concrete layer re-cracking and protect the concrete surface edges of the joint spaces against spalling by repeated impact loading. Inserts embedded in the fillers locationally restrict stress-induced fracture to the joint spaces and in spaced relation to the concrete bonding interfaces of the fillers so as to maintain filler protection for the concrete edges against spalling damage.
