A Study of Asphalt Mats for Gravity-type Maritime Structures

Abstract

Asphalt mats with cold ocean gravity structures is an economic construction method because the coefficients of friction can be increased. However, flexibility and the visco-elastic response of mats which contribute much to the sliding resistance decrease at sea water temperatures below 0°C. In summer, temperatures inside the asphalt mats rise at manufacturing yard. An investigation has been made to develop mix proportions of asphalt mats which are less sensitive to temperature, and so suitable for the wide change in temperatures in cold oceans.
