AUTOBAHN ASPHALTOBERBAU

FULL DEPTH PAVEMENT CONSTRUCTION ELIMINATES THE NEED FOR A FROST PROTECTION LAYER UNDER THE BASE COURSE. IT CONSISTS OF EMPLOYING ASPHALT MIXTURES FOR ALL COURSE ABOVE THE SUBGRADE OR IMPROVED SUBGRADE. TWO TEST SECTIONS WERE PLACED ON A FEDERAL (GERMAN) HIGHWAY BEFORE ISSUANCE OF A PRACTICAL THICKNESS DESIGN METHOD SUITED TO GERMAN CONSTRUCTION. FOLLOWING TESTS, FULL-DEPTH WAS USED FOR REBUILDING AND WIDENING A SECTION OF ONE OF THE COUNTRY'S MOST HEAVILY TRAVELED ROUTES. THE PROJECT SERVED TO DEMONSTRATE THE EFFICACY OF THE METHOD AND ITS INHERENT ECONOMY. THE CAMBERG FULL-DEPTH DESIGN COMPRISES 16 INCHES OF ASPHALT MIXTURES PLACED DIRECTLY ON IMPROVED SUBGRADE. GUSSASPHALT WAS APPLIED TO THE PAVEMENT AS A DURABLE, SKID-RESISTANT FINISH. PERFORMANCE EVALUATIONS ON THE PROJECT ARE CONTINUING. BENKELMAN BEAM DEFLECTION MEASUREMENTS, TEMPERATURE AND SOIL MOISTURE CONTENTS, SMOOTHNESS AND SKID RESISTANCE READINGS WILL BE MADE.
