EXPERIENCE WITH FLEXIBLE PAVEMENTS IN MARYLAND

THE HISTORICAL DEVELOPMENT IS PRESENTED OF THE DESIGN AND CONSTRUCTION OF FLEXIBLE PAVEMENTS IN MARYLAND AND THE STRUCTURAL ADEQUACY OF PAVEMENTS BUILT ACCORDING TO THE PROVISIONS OF THE METHOD OF DESIGN CURRENTLY IN USE. THIS METHOD UTILIZES CBR VALUES OF THE SUBGRADE SOIL AS A BASIS OF DETERMINING THE THICKNESS OF SUBBASE MATERIAL NECESSARY AS AN INTERFACIAL LAYER ON THE SUBGRADE BENEATH EITHER OF TWO STANDARD SECTIONS. ONE OF THE STANDARD SECTIONS IS FOR TRAFFIC OF 2,000 VEHICLES OR MORE PER DAY AND CONSISTS OF 10 INCHES OF MACADAM BASE AND 3 1/2 INCHES OF ASPHALTIC CONCRETE, THE OTHER IS FOR TRAFFIC LESS THAN 2,000 VEHICLES PER DAY AND CONSISTS OF 8 INCHES OF MACADAM BASE AND 2 INCHES OF ASPHALTIC CONCRETE. THE SERVICE BEHAVIOR OF THE MAJORITY OF PAVEMENTS BUILT IN THE STATE DURING THE PAST SEVERAL YEARS USING THE METHOD HAS BEEN SATISFACTORY. /AUTHOR/
