Title: PERFORMANCE OF CONCRETE PAVEMENTS ON GRANULAR SUBBASE
Accession Number: 00206942
Record Type: Component
Abstract: ALL NEW CONCRETE PAVEMENT IN ILLINOIS HAS BEEN PLACED ON GRANULAR SUBBASE WHERE THE NATURAL SOIL IS FINE-GRAINED AND HEAVY TRUCK TRAFFIC IS EXPECTED. THE LOWER COST OF CONSTRUCTING THE TRENCHED UNDRAINED SUBBASE WAS A DECIDING FACTOR IN THE PREFERENCE SHOWN FOR THIS TYPE OF SUBBASE. STUDIES OF THESE GRANULAR SUBBASES INDICATE THAT THEY HAVE BEEN EFFECTIVE IN THE CONTROL OF PUMPING. ALTHOUGH SOME PUMPING OCCURRED ON GRANULAR SUBBASE MATERIALS, THE PROBLEM HAS NOT BEEN OF IMPORTANCE. SHOULDER HOLES WERE FOUND TO BE FAIRLY COMMON, THOUGH NO PAVEMENT FAILURES COULD BE ATTRIBUTED TO THEIR PRESENCE AND NO DIRECT CONNECTION BETWEEN THEM AND PUMPING WAS ESTABLISHED. IT IS CONCLUDED THAT FILLING THE SHOULDER HOLES AND SHAPING HE SHOULDERS TO LINES AND GRADES THAT PREVENT THE ENTRAPMENT OF WATER ADJACENT OT THE PAVEMENT EDGES WILL BE A PROFITABLY EXPENDED MAINTENANCE EFFORT.
