Abstract

Evaluates how effective stress-absorbing layers are in reducing the seasonal build-up of lateral pressures caused by thermal expansion of the deck of an integral bridge. Relates measurements taken of changes in deck length, strains and temperatures in the deck, lateral earth pressures acting on the abutments, changes in the thickness of the stress absorbing layers and settlement behind the abutments. Identifies instrumentation used. Discusses the implications of the findings upon the design procedures for integral bridges.
