Civil engineering structures, such as bridges, flyovers and underbridges, are discontinuities in a concrete road. Usually, the concrete pavement has to be cut across and in those cases, such as small underbridges, where the concrete pavement can be laid without any discontinuity, differential settlements between embankment and structure have to...
Connecting devices between concrete road pavements and existing highway structures
Side drainage and sub-soil drainage layer operation and performance
A very favourable result emerges from the assessment of the soundness of structural arrangements adopted and developed over the past ten years (3rd International Conference at Purdue, April (985). After briefly reviewing this positive achievement resulting from closely concerted action of road managers, practical engineers and researchers, the authors more...
Spanish realizations of steel fiber pavements
The development of the steel fiber reinforced concrete pavements has experienced a big apogee in Spain in the last three years. The object of this work is to display the most important realizations made in the field of roads. harbours, airports, etc., analyzing their characteristics and behaviour. ROADS - Base...
Economic appraisal of cement concrete versus asphaltic concrete pavements
1. Introduction Since 1962 no cement concrete had been used in the governmental road sy~tem as a paving material. After 1975 the need to use this material again was felt more and more. Somewhere about 1982, during the decision making period regardi~g the type of pavement to be chosen for...
