FLEXIBLE BASE CONTROL

A METHOD IS DESCRIBED OF DETERMINING THE AMOUNT OF FLEXIBLE BASE MATERIAL REQUIRED FOR BASE SECTIONS. AFTER CALCULATING THE APPARENT ACTUAL DENSITY /DA/ OF THE MATERIAL FROM THE DESIGNATED MATERIAL SOURCE BY PRELIMINARY LABORATORY TESTS, FORMULAS ARE USED TO ESTIMATE THE QUANTITY FOR EACH GRADE OF FLEXIBLE BASE SPECIFIED PER 100-FOOT STATION. THE ALLOWANCE FOR CONTINGENCIES TAKES INTO CONSIDERATION DEFICIENCIES THAT MAY EXIST IN FINISHED SUBGRADES OR BOTTOM BASE COURSES, POSSIBLE SLIGHT VARIATIONS IN BASE WIDTHS, AND THE SMALL AMOUNT CUSTOMARILY ACCEPTABLE FOR THE BASE FINISHING OPERATION.
