INTERIM REPORT #1 - CONSTRUCTION DOCUMENTATION OF AN EXPERIMENTAL CONCRETE PAVEMENT

THE CATSKILL-CAIRO TEST ROAD COMBINES A VARIETY OF SUBGRADE CONDITIONS WITH VARIOUS SUBBASE AND BASE MATERIALS AND SEVERAL PAVEMENT DESIGNS. IN ALL, 30 DIFFERENT TEST SECTIONS HAVE BEEN SELECTED FOR STUDY FROM THE COMBINATION OF NATURALLY OCCURRING AND EXPERIMENTAL FEATURES. EXTENSIVE TESTING DURING CONSTRUCTION, SUMMARIZED HERE, PROVIDES THE NECESSARY BACKGROUND TO EVALUATE THE RELATIVE PERFORMANCE OF THE EXPERIMENTAL FEATURES. IN ADDITION, SEVERAL CONCLUSIONS ARE PRESENTED CONCERNING THE VALIDITY OF CERTAIN VARIABLES AND THE OVERALL DESIGN OF THE EXPERIMENT. AMONG THE MAJOR CONCLUSIONS PRESENTED IN THIS REPORT ARE: (1) THE TWO TYPES OF SUBBASE MATERIALS USED, FOR ALL PRACTICAL PURPOSES, ARE IDENTICAL. (2) THE SLIP FORM PAVER IS A SATISFACTORY METHOD OF CONSTRUCTING CONCRETE PAVEMENT. (3) THE VALIDITY OF THE PLATE BEARING TEST AND THE VALUE OF THE RESULTING SUBGRADE SUPPORT MODULUS K ARE QUESTIONABLE. (4) THE PAVEMENT THICKNESS VARIABLE WAS INVALIDATED DUE TO CONSTRUCTION VARIATION. SEVERAL OTHER CONCLUSIONS CONCERNING MATERIALS, TEST METHODS, AND DESIGN OF EXPERIMENT ARE ALSO PRESENTED AND DISCUSSED. /AUTHOR/
