PAVEMENT DESIGN AND CONTROL

THIS REPORT DESCRIBES TWO RATIONAL METHODS OF DESIGNING FLEXIBLE PAVEMENTS SUBJECTED TO HEAVY TRAFFIC AND A PROCEDURE FOR DETERMINING THE PROPERTIES OF THE ROAD BED. THE FIRST METHOD IS BASED ON THE ULTIMATE ELASTIC DEFLECTION UNDER A STANDARD TRUCK WHEEL, WHICH FOR A GIVEN TRAFFIC INTENSITY DOES NOT RESULT IN PAVEMENT FATIGUE OR FLEXION STRESSES GREATER THAN ALLOWABLE. THE SECOND METHOD IS BASED ON THE PREVENTION OF LOCAL SHEARING IN THE COHESIONLESS MATERIALS OF THE ROAD BED AND SUBSEQUENT COURSES. BOTH METHODS CAN BE USED TO DESIGN FLEXIBLE PAVEMENTS, DETERMINE THEIR STABILITY AND ESTABLISH LIMITING WHEEL LOADS DURING UNFAVOURABLE SEASONS. TWO PIECES OF TRUCK-MOUNTED EQUIPMENT ARE DESCRIBED FOR MEASURING THE HOMOGENEITY OF THE ROAD BED AND SUBSEQUENT COURSES. /AUTHOR/
