FLEXIBLE PAVEMENTS OR USE OF CONCRETE?

STARTING WITH THE BURMISTER MULTI-LAYER THEORY THE AUTHOR ATTEMPTS TO ESTABLISH ROAD CONSTRUCTION METHODS WHICH ARE MORE ECONOMICAL THAN THE STANDARD CONSTRUCTION METHODS INTRODUCED IN THE FEDERAL REPUBLIC BOTH IN TERMS OF PRODUCTION COSTS AND THE EXPECTED LIFE OF THE STRUCTURE. THE DESIGN OF ROADS IN ACCORDANCE WITH THE MULTI-LAYER THEORY HAS SHOWN THAT OPTIMUM DIMENSIONS OF THE INDIVIDUAL LAYERS CAN BE ATTAINED IF THE STIFFNESS OF THE MATERIALS FORMING THE LAYERS INCREASES AS UNIFORMLY AS POSSIBLE FROM THE SUBSOIL TO THE SURFACING. AS A RESULT THERE ARE LESS STRESSES THAN WITH THE STANDARD CONSTRUCTION METHOD. THIS TYPE OF STRUCTURE IS ACHIEVED FOR EXAMPLE BY INSERTING A CONCRETE LAYER BETWEEN THE GRAVEL FROST BLANKET AND THE BITUMINOUS ROADBASE. THE AUTHOR GIVES DETAILS OF AN EXPERIMENTAL ROAD OF THIS TYPE WHICH HAS BEEN BUILT NEAR GOETTINGEN, AND COMPARES IT WITH THE FLEXIBLE METHOD OF CONSTRUCTION (BITUMINOUS ROADBASE DIRECTLY ON GRAVEL FROST BLANKET) USED ON A SECTION OF THE COLOGNE-FRANKFURT MOTORWAY AT CAMBERG. /TRRL/
