METHOD FOR CALCULATING EQUIVALENT 18-KIP LOAD APPLICATIONS
AN INVESTIGATION INTO FACTORS AFFECTING 18-KIP SINGLE-AXLE LOAD APPLICATIONS (EWL 18) WAS MADE BY USING RESULTS OF TRUCK WEIGHT AND LOADOMETER DATA FROM 47 STATES. IT WAS FOUND THAT EWL 18 CORRELATED WELL WITH THE NUMBER OF HEAVY TRUCKS, BUT THE CORRELATION COEFFICIENTS VARIED CONSIDERABLY AMONG STATES. A SIMILAR STUDY USING ONLY ADT ALSO SHOWED CONSIDERABLE VARIATION AMONG BOTH STATES AND HIGHWAY CLASS WITHIN A GIVEN STATE. BOTH OF THESE WERE NOT AS GOOD AS RELATIONSHIPS USING SOME MEASURE OF AVERAGE AXLE WEIGHT OR AVERAGE TRUCK GROSS WEIGHT. THE MOST USEFUL RELATIONSHIP AND HIGHEST CORRELATION OF ALL THOSE INVESTIGATED WAS FOUND AMONG EWL 18, LEGAL AXLE LOAD LIMIT, AVERAGE HEAVY TRUCK WEIGHT, AND NUMBER OF HEAVY TRUCKS. /AUTHOR/
