MEASUREMENTS ON THE EXPERIMENTAL CONSTRUCTION WITHOUT THE REMOVAL OF THE SUBGRADE ON THE BREMEN-HAMBURG FEDERAL MOTORWAY, PART 2

MESSUNGEN AUF DER VERSUCHSSTRECKE HOCHEINBAU DER BAB BREMEN - HAMBURG, 2. TEIL

IN AN EARLIER PROJECT COMPREHENSIVE MEASUREMENTS WERE MADE ON A CONTINUOUSLY REINFORCED CONCRETE PAVEMENT BUILT WITHOUT REMOVAL OF THE EXISTING SUBGRADE. FURTHER OBSERVATIONS ARE TO BE MADE ON THIS EXPERIMENTAL SECTION OF ROAD FOLLOWING THE SEVERE FROST OF FEBRUARY 1978, AFTER WHICH SEVERAL JOINTS HAD OPENED WIDELY. IT IS INTENDED TO MEASURE THE JOINTS TWO OR THREE TIMES A YEAR, AND THESE MEASUREMENTS ARE TO BE UNDERTAKEN AT THE SAME TIME AS THOSE FOR ANOTHER PROJECT (SEE IRRD RESEARCH PROJECT NO 701932) TO REDUCE TRAVEL COSTS. IF NECESSARY MEASUREMENTS OF SETTLEMENT WILL ALSO BE CARRIED OUT TO EVALUATE BEARING CAPACITY.
