CONDITION SURVEY OF ROUTE 66
THE ROUTE U.S. 66 CONDITION SURVEY FURNISHED A LARGE QUANTITY OF ESSENTIAL DATA THAT WAS USED IN MODIFYING THE FORMULAS DEVISED TO DEPICT THE LOAD-CONDITION RELATIONSHIPS DEVELOPED AT THE AASHO ROAD TEST TO PRODUCE PAVEMENT DESIGN EQUATIONS THAT REPRESENTED ACTUAL SERVICE CONDITIONS IN ILLINOIS. THE SURVEY ALSO FURNISHED A CONSIDERABLE AMOUNT OF QUALITATIVE INFORMATION ON PAVEMENT AND SHOULDER DESIGNS AND MATERIALS IN USE IN ILLINOIS. THIS FINAL SUMMARY REPORT BRIEFLY DESCRIBES THE LOCALE OF THE STUDY, THE PAVEMENTS AND OTHER FEATURES UNDER OBSERVATION, AND THE SURVEY TECHNIQUES EMPLOYED. RESULTS, PRIMARILY OF A QUALITATIVE NATURE, ARE PRESENTED. A RETROSPECTIVE CRITIQUE OF THE SURVEY IS INCLUDED FOR THOSE GIVING CONSIDERATION TO UNDERTAKING CONDITION SURVEYS. A VARIETY OF RIGID PAVEMENT DESIGN FEATURES THAT FOLLOWED NATIONAL TRENDS THROUGH THE YEARS BEGINNING IN 1926 WERE INCLUDED IN THE OBSERVATION. BITUMINOUS CONCRETE RESURFACINGS BECAME A PROMINENT FEATURE DURING THE LATTER YEARS OF THE SURVEY. GRANULAR SUBBASES TO COMBAT MUD-PUMPING WERE A PART OF THE RIGID PAVEMENT CONSTRUCTION BEGINNING IN THE EARLY 1940'S. PAVED SHOULDERS ADOPTED DURING THE LATTER STAGES OF THE SURVEY WERE STUDIED IN AN AUXILIARY INVESTIGATION. /AUTHOR/
