Title: AN EXPERIMENTAL SELF-STRESSING CONCRETE PAVEMENT: II. FOUR-YEAR PAVEMENT EVALUATION
Abstract: DURING THE 1963 PAVING SEASON, AN EXPERIMENTAL REINFORCED CONCRETE PAVEMENT WAS CONSTRUCTED IN WHICH AN EXPANSIVE CEMENT WAS USED TO PRODUCE THIN PRESTRESSED SLABS. THE EXPERIMENTAL SECTION CONTAINS THREE SLABS 24 FT WIDE, 6 IN. THICK, AND APPROXIMATELY 490 FT LONG. THE CONVENTIONAL PAVEMENT, OF 40-FT CONTRACTION JOINT DESIGN, IS PLACED 9 IN. THICK IN TWO 12-FT LANES. THIS REPORT IS DEVOTED TO THE 4-YEAR, POST-CONSTRUCTION PERFORMANCE OF THIS PAVEMENT. SLAB MOVEMENT DATA, CRACK OBSERVATION, AND OTHER INFORMATION ARE PRESENTED, AS WELL AS SUGGESTIONS FOR THE FUTURE APPLICATION OF THIS SELF-STRESSING TECHNIQUE. EARLY CONSTRUCTION DIFFICULTIES AND PAVEMENT DISTRESS APPEAR TO HAVE SIGNIFICANTLY AFFECTED THE PAVEMENT PERFORMANCE TO DATE. TRANSVERSE CRACKING THAT HAS DEVELOPED IN THE TEST SECTION IS PROBABLY RELATED TO INSUFFICIENT PRESTRESS IN THE CONCRETE SLABS. /AUTHOR/
