ASPHALT CONCRETE PAVEMENT AND PERMEABILITY

THE PERMEABILITY OF ASPHALTIC CONCRETE PAVEMENTS TO AIR AND WATER APPEARS TO BE A PRIMARY FACTOR IN CONTROLLING PAVEMENT DURABILITY. A HIGH PERMEABILITY OF AN ASPHALTIC PAVEMENT CAN SERIOUSLY AFFECT THE DURABILITY OF A ROADWAY. THE SUBJECT OF THIS PAPER IS A VERY GENERAL ONE AND TOUCHES ON THE PROBLEM OF PERMEABILITY AND CONSTRUCTION PRACTICES. THE PERMEABILITY MEASUREMENTS IN THIS INVESTIGATION WERE MADE USING AIR AND WATER PERMEABILITY DEVICES. BOTH INSTRUMENTS WERE PORTABLE AND THE METHODS OF MEASUREMENT WERE RAPID. DATA ACCUMULATED IN THE FIELD ARE ALSO SHOWN. THE RESULTS OF THIS STUDY INDICATE /1/ THE USE OF SOME TYPE OF FLOW RATE DEVICE SEEMS WARRANTED AS AN INDICATOR OF IN- PLACE ASPHALTIC CONCRETE COMPACTION DURING CONSTRUCTION, /2/ ON VERY DENSE PAVEMENTS AIR FLOW RATES SEEM TO BE MORE SENSITIVE INDICATORS OF COMPACTION THAN WATER FLOW RATES, AND /3/ BASED ON TRENDS SHOWN, MUCH CARE SHOULD BE TAKEN IN THE ROLLING AND COMPACTION OF HOT ASPHALTIC CONCRETE. /AUTHOR/
