ATTEMPTS HAVE BEEN MADE TO OBTAIN THE BENEFITS OF CONTINUOUS PAVEMENT DESIGNS WITHOUT THE LARGE AMOUNTS OF STEEL IN CONTINUOUSLY REINFORCED AND RANDOMLY CRACKED ROADS. THE DESIGNS USE WEAKENED PLANE JOINTS WITH STEEL TIES CROSSING THE JOINTS (ELASTIC JOINTS) TO FORM TRANSVERSE HINGES ACROSS THE PAVEMENT. IN COMMON PRACTICE, CONTRACTION JOINTS HAVE BEEN USED INTERMITTENTLY AS EVERY FOURTH OR FIFTH JOINT TO AVOID EXCESSIVE STRESSES IN THE CONTINUOUS STEEL IN BETWEEN. CONTINUOUS PAVEMENTS USING ELASTIC JOINTS EXCLUSIVELY HAVE BEEN EXPLORED IN SWEDEN. CONTROLLED SLAB TENSION TESTS AND JOINT-WIDTH MEASUREMENTS HAVE GIVEN DATA ON JOINT-CRACKING FORCES AND MOVEMENTS AND ON FULL-SECTION CRACKING. THE EFFECTIVENESS OF DIFFERENT BAR BOND BREAKERS AND CORRESPONDING ELASTIC JOINT FORCES WAS OBSERVED. AN INITIAL SHORT HIGHWAY INSTALLATION INDICATED THAT 0.2 PERCENT CONTINUOUS STEEL AND ELASTIC JOINTS COULD BE USED, WITH THE BARS COATED WITH ASPHALT TO PREVENT BOND FOR A SHORT DISTANCE UNDER THE ELASTIC JOINTS. THE HIGHWAY INSTALLATION WAS INSPECTED AFTER THREE YEARS OF USE AND FOUND TO BE IN EXCELLENT CONDITION. NO RANDOM CRACKS OR OTHER DETERIORATION COULD BE SEEN. ALTHOUGH TRAFFIC WAS LIGHT COMPARED TO THAT ON AMERICAN DIVIDED HIGHWAYS, A LARGE PERCENTAGE WAS TRUCKS. /AUTHOR/
