OPTIMIZATION OF HAUL FLEET SIZE AND DISTANCE BETWEEN PLANT MOVES ON HIGHWAY PAVING PROJECTS
EQUIPMENT CONFIGURATIONS AND PROCEDURES ON HIGHWAY PAVING PROJECTS WERE INVESTIGATED, AND A MEANS OF OPTIMIZING HAUL FLEET SIZE AND DISTANCE BETWEEN PLANT MOVES IS DISCUSSED. THE SIMULATION PROGRAM USED TO PREDICT PRODUCTION RATES IS DESCRIBED, AND A METHOD IS GIVEN FOR OBTAINING PRODUCTION IN TRUCKLOADS PER HOUR FROM THE PLOTS OF THE SIMULATION RESULTS WITHOUT THE NEED TO RUN THROUGH SEVERAL APPROXIMATIONS. SIX PAVING CONFIGURATION AND PROCEDURE MODELS ARE ANALYZED WITH REGARD TO COST PER CUBIC YARD OF CONCRETE IN PLACE FOR DIFFERENT TRUCK FLEET SIZES OR FOR RATES OF PAVING ADVANCE IN CONJUNCTION WITH DIFFERENT DISTANCES BETWEEN PLANT MOVES FOR EACH MODEL, LEAST-COST COMBINATION, AND LEAST-COST MODEL. THE STUDY REVEALED THAT SIMULATION IS ONE MEANS OF OBTAINING THE PRODUCTION RATES NEEDED FOR ANALYSIS OF PAVING SPREAD CONFIGURATIONS AND PROCEDURES. PLOTS ON LOG-LOG GRAPH PAPER WERE FOUND TO PROVIDE AN ECONOMICAL MEANS TO EXTRAPOLATE THE SIMULATED DATA. SIMULATION SHOWS THAT STEADY STATE IS ALWAYS REACHED IN A PAVING OPERATION AND USUALLY BETWEEN THE SECOND AND THIRD HOUR AFTER START OF PRODUCTION. MATHEMATICAL MODELING, IT WAS FOUND, ALLOWS A MEANS FOR ANALYZING DIFFERENT PAVING SPREAD CONFIGURATIONS AND PROCEDURES. A CONSIDERABLE DIFFERENCE WAS NOTED IN COST OF CONCRETE IN PLACE, DEPENDING ON THE PAVING SPREAD CONFIGURATION AND PROCEDURE USED. THE SENSITIVITY OF MODELS IN THE AREAS OF PRODUCTION AND NUMBER OF TRUCKS, MAKES THE PROCESS OF PICKING THE LEAST-COST COMBINATION WITHIN A MODEL, A DIFFICULT ONE. DETAILS ARE GIVEN OF THE REDUCTION OF DATA AND THE RESULTS OF THE ANALYTICAL STUDY.
