HOT-MIX ASPHALT PRACTICES - WEST GERMANY

GUSSASPHALT IS A DENSELY GRADE, POURABLE ASPHALTIC MIXTURE WITH ZERO VOIDS THAT WAS DEVELOPED BY WEST GERMAN TECHNOLOGISTS. AT PRESENT, FULLY FLEXIBLE CONSTRUCTION WITH VARIOUS TYPES OF ASPHALTIC CONCRETE MIXES ACCOUNT FOR 40% OF ALL NEW CONSTRUCTION IN WEST GERMANY. A COMMON PRACTICE IS TO PLACE A MINIMUM OF 7 INCHES OF ASPHALTIC CONCRETE BASE ON THE ROADWAY, 3.5 INCHES OF SPECIAL BINDER COURSE, AND 1.5 INCHES OF GUSSASPHALT. HOT-MIX PREPARATION AND TRANSPORTATION, AGGREGATES, THE MIX FORMULA, AND LAYING PROCEDURES ARE DESCRIBED. THE SPECIFICATIONS FOR AN IMPROVED VERSION CALLED RAUHGUSSASPHALT ("RAW MASTIC") ARE NOTED BRIEFLY. INSPECTIONS MADE 8--10 YEARS AFTER SURFACING ON ROADS WITH 87--124,000 ADT COUNTS SHOWED THE ROADS TO BE IN EXCELLENT CONDITION AND FREE OF REFLECTION CRACKING ON CHANNELING, EVEN UNDER HEAVY TRUCK TRAFFIC IN HOT WEATHER.
