There was also a consensus of opinion that the time had come to give up the universal application of rigid construction usual in Britain and to adopt a more generally flexible construction. He was very much in agreement with that, and he was attracted to the idea put forward on the subject of composite construction—flexible pavements in conjunction with rigid slabs.
