Abstract:

Many important issues about bearings were identified by Fritz Leonhardt, keynote speaker at the Congress. His main point was that bearings should be designed and installed to function effectively for up to 100 years. Problems in achieving this goal were discussed. . .The session identified areas in which additional work is needed; these are summarized in a table. The resolution, carried during the Congress, to form a permanent technical committee on bearing systems, a companion to ACI Committee 504, Joint Sealants, is a first step in improving communications. The Congress, attended by over 300 people, was an outstanding success.

Abstract:

This technical note describes the influence of wind speed on the thermal behavior of bridges. It supplements the paper 'Thermal Movements of Concrete Bridges: Field Measurements and Methods of Prediction' published in Volume 1 of the Proceedings. A theoretical method of calculating bridge termperatures was developed which gave good agreement with measured values. Using this theoretical method, it is shown that the influence of the wind speed is greater on the values of the maximum bridge temperature than on the minimum values.

Abstract:

Many years experience has proven there are essential elements that must be considered in designing joints in Portland cement concrete pavements for highways and airfields, to insure longevity of the sealant to perform to keep the joints sealed against the infiltration of water, moisture, or incompressibles, or against the infiltration of water, moisture, or incompressibles, or jet fuel spillage in airfield critical areas.

Abstract:

This technical note describes several expansion joint and drainage details used on bridges in Europe. The details include a technique to prevent deterioration of bituminous surfacings at expansion joints, an adjustable drainage grating, a combination drainage/ventilation element and an expansion bellows to prevent damage to utility pipes from movement of the bridge.

Abstract:

Major advances in the field of tunnelling have been achieved in the post-War period, particularly in relation to machine mining and the development of precast concrete segmented linings. The principal challenge which must now be overcome is the perfecting of waterproofing systems for segmented linings. . .The other waterproofing components: interior linings, patching techniques and the development of superior concretes could form the basis of a subequent paper on the subject.
