UNDERCARRIAGE EFFECTS ON (A) RIGID PAVEMENTS (B) FLEXIBLE PAVEMENTS

OBSERVED MODES OF FAILURE IN FLEXIBLE AND RIGID PAVEMENTS ARE EXAMINED AND CRITERIA FOR DESIGN AND EVALUATION, BASED UPON THESE OBSERVATIONS, ARE SUGGESTED FOR DIFFERENT CATEGORIES OF PAVEMENTS. FOR EACH CATEGORY, GRAPHS ARE PRESENTED OF LOAD PLOTTED AGAINST TIRE PRESSURE FOR A RANGE OF UNDERCARRIAGE ARRANGEMENTS AND FOR DIFFERENT SUBGRADE CHARACTERISTICS. THE GRAPHS ARE BASED ON TEST AND EXPERIMENTAL WORK AND COMPUTER CALCULATIONS; THEIR DERIVATION AND VALIDITY ARE DISCUSSED. THE CONCEPT OF THE EQUIVALENT SINGLE WHEEL LOAD AND THE LOAD CLASSIFICATION NUMBER IS BRIEFLY DESCRIBED AND SOME INCOMPATIBILITIES ARE IDENTIFIED. A DISCUSSION IS APPENDED. /TRRL/
