SIMULATED APPLICATION OF A STATISTICALLY BASED SPECIFICATION FOR ASPHALTIC CONCRETE CONSTRUCTION

THE SIMULATED ACCEPTANCE TEST RESULTS OBTAINED FROM RANDOMLY SELECTED SITES OR SAMPLES SHOWED THAT THE CONTRACTOR'S PAYMENT WOULD HAVE AVERAGED APPROXIMATELY 97 PERCENT OF CONTRACT BID PRICE FOR 32 DAYS PRODUCTION. ACCEPTANCE WAS BASED ON SUCH FACTORS AS AGGREGATE GRADATION, ASPHALT CONTENT, CORE DENSITY AND RIDEABILITY. ON TWO OF THE THREE PROJECTS, MOVING AVERAGE OF 5, CONTROL PRODUCTION FOR THE NO. 50 AND NO. 200 SIEVES. MOST OF THE BID PRICE REDUCTION FOR THESE TWO PROJECTS WAS ALSO ATTRIBUTED TO ABOVE TARGET PRODUCTION AS INDICATED BY SIMULATED ACCEPTANCE TESTS. ON THE THIRD JOB MOST OF THE REDUCED PAYMENT WAS CAUSED BY ROUGH PAVEMENT READINGS ON ALL BUT 2 OF THE 13 LOTS. /FHWA/
