THE TIME LAG IN SOIL-CEMENT DESIGN TESTING AND LOUISIANA'S APPROACH TO ITS REDUCTION

LOUISIANA, BEING PREDOMINANTLY A DELTA DEPOSIT LAND FORMATION, LACKS LARGE DEPOSITS OF SELECT MATERIALS FOR BASE COURSES. CEMENT-STABILIZED BASE COURSES WERE FIRST USED IN THE LATE 1930'S, AND SINCE 1939 THE SOILS UNIT OF THE HIGHWAY DEPARTMENT HAS MAINTAINED RECORDS OF ALL SOILS TESTED FOR CEMENT STABILIZATION. THE DEPARTMENT NOW HAS A CATALOG OF OVER 9000 SAMPLES FROM ABOUT 2200 PROJECTS. THIS CATALOG HAS BEEN ANALYZED TO DISTINGUISH SOIL TYPES BY PARISH, WHICH IS GENERALLY POSSIBLE WITH A FEW EXCEPTIONS. A SYSTEM FOR THE GENERAL RULE THAT ALSO EMBRACES THE EXCEPTIONS HAS BEEN DEVISED AND CORRELATED WITH SOIL CEMENT MIX DESIGNS. BOTH THE AASHO AND DEPARTMENT OF AGRICULTURE CLASSIFICATION SYSTEMS ARE USED IN DETERMINING THE PROPER APPLICATION RATE.
