URBAN PAVING IN STATE ROADS COMMISSION, DISTRICT 3 (MONTGOMERY AND PRINCE GEORGES COUNTIES)

EXAMPLES ARE GIVEN OF HIGH TYPE URBAN HIGHWAYS CONSTRUCTED OF FLEXIBLE PAVEMENTS IN THE PAST FEW YEARS. ACTIVITIES DISCUSSED ARE: (1) UTILITY PREPARATION AND REQUIREMENTS, (2) MAINTENANCE AND CONTROL OF TRAFFIC DURING CONSTRUCTION, (3) VARIOUS PAVEMENT DESIGNS AND THEIR PLACE IN URBAN PAVING, (4) CONSTRUCTION TECHNIQUES AND REQUIREMENTS FOR SUCCESSFUL PAVING EFFORT, AND (5) ACTIVITIES SUBSEQUENT TO PLACING THE URBAN PAVING AND TRAFFIC ON THE FINISHED ROADWAY. THOSE PAVEMENTS DESIGNED AND CONSTRUCTED USING MAINLY BITUMINOUS CONCRETE HAVE PROVIDED THE QUICKEST, MOST STRUCTURALLY CAPABLE, EFFICIENT, ECONOMICAL, AND SATISFYING CONSTRUCTION EFFORTS. ADVANTAGES OF USING THESE PAVEMENTS ARE: (1) LESS EXCAVATION, (2) LESS CONSTRUCTION TIME, (3) SAME EQUIPMENT AND MEN CAN BE USED ON THE BULK OF THE WORK, (4) INSPECTION FORCES HAVE LESS DIFFERENT TYPE OF MATERIALS TO INSPECT, (5) MAINTENANCE OF TRAFFIC IS SIMPLIFIED AND LESS COSTLY, (6) ONCE BITUMINOUS CONCRETE BASE COURSE IS PLACED THERE ARE NO DELAYS AFTER INCLEMENT WEATHER, (7) NO WAITING FOR A SECOND, THIRD, OR FOURTH TYPE OF MATERIAL, AND (8) NO EXTENDED CURING PERIOD. IT IS SHOWN THAT THE USE OF OLD PAVEMENT AS A PART OF THE PAVEMENT SECTION WAS BENEFICIAL IN THE URBAN PROJECTS. TWO RECOMMENDATIONS ARE MADE TO EXPEDITE CONSTRUCTION AND SAVE MONEY ON URBAN PROJECTS: (1) SIMPLIFY PAVEMENT DESIGNS BY ELIMINATING THE MULTITUDE OF THE VARIOUS GRADED AGGREGATE COURSE, AND (2) ELIMINATE THE CALENDAR DATES FOR BITUMINOUS CONCRETE PAVING, EXCEPT FOR SURFACE COURSES.
