Q, SCALE IN FEET
Q. POROUS PAVEMENT NOTES:
TO PREVENT COMPACTION WHEN INSTALLING THE
AGGREGATE BASE, THE FOLLOWING STEPS (BACK DUMPING)
SHOULD BE FOLLOWED:
• THE AGGREGATE BASE IS DUMPED ONTO THE SUBGRADE
FROM THE EDGE OF THE INSTALLATION AND AGGREGATE IS
O THEN PUSHED OUT ONTO THE SUBGRADE;
• TRUCKS THEN DUMP SUBSEQUENT LOADS FROM ON TOP
rR OF THE AGGREGATE BASE AS THE INSTALLATION
V PROGRESSES. AVOID SUBGRADE PREPARATION DURING
z WET PERIODS (SOIL COMPACTION INCREASES
Y SIGNIFICANTLY IF SOIL IS WET).
• IF MACHINERY MUST ACCESS THE FINAL GRADE, LIMIT THE
Q ACCESS TO A SPECIFIC TRAVEL WAY THAT CAN BE TILLED
a. BEFORE APPLICATION OF THE BASE AGGREGATE OR PLACE
z HEAVY STEEL PLATES ON SUBGRADE AND LIMIT TRAFFIC TO
O THE PROTECTIVE COVER.
• EXCAVATE THE SUBGRADE LEVEL TO ALLOW EVEN
z DISTRIBUTION OF WATER THROUGH THE AGGREGATE BASE
w AND MAXIMIZE INFILTRATION ACROSS THE ENTIRE PARKING
AREA
• IMMEDIATELY BEFORE PLACING BASE AGGREGATE AND
1
U) PAVEMENT, REMOVE ANY ACCUMULATION OF FINE
U) MATERIAL (IF PRESENT) WITH LIGHT EQUIPMENT AND
w SCARIFY SOIL TO A MINIMUM DEPTH OF 6 INCHES TO
PREVENT SEALING OF THE SUBGRADE SURFACE.
• WHILE THE SUBGRADE IS EXCAVATED LEVEL, THE
X PAVEMENT SURFACE SHOULD MAINTAIN A MINIMAL SLOPE
W OF 1 TO 2 PERCENT.
w PAVEMENT OR WEARING COURSE INSTALLATION
J • THE POROUS ASPHALT PAVEMENT INSTALLATIONS USE THE
SAME EQUIPMENT AND SIMILAR PROCEDURES AS
CONVENTIONAL ASPHALT WITH THREE NOTABLE
DIFFERENCES:
• MIXING TEMPERATURE SHOULD BE 260 -280 F AND 240 -260
(f� F FOR LAY DOWN. AIR TEMPERATURE SHOULD BE NO
LOWER THAN 45 F AND RISING.
• THE STIFFER PERFORMANCE GRADE FOR THE BITUMINOUS
ASPHALT CEMENT ADHERES MORE TO DELIVERY TRUCKS
AND INSTALLATION MACHINERY; ACCORDINGLY,
ADDITIONAL TIME IS NECESSARY TO CLEAN EQUIPMENT.
• POROUS ASPHALT AGGREGATE BASE AND CHOKER COURSES
ARE RELATIVELY UNIFORM GRADATIONS AND LOW IN FINE
MATERIAL. AS A RESULT, EQUIPMENT OPERATING ON THE
AGGREGATE BASE WILL CAUSE MORE RUTTING THAN ON
MORE DENSELY GRADED BASE MATERIAL FOR
CONVENTIONAL PAVEMENT AND WILL REQUIRE MORE
HAND LABOR TO SMOOTH RUTS AND PREVENT AREAS
WHERE THE PAVEMENT IS EITHER TOO THIN OR TOO THICK.
MINIMUM INFILTRATION RATE FOR THE POROUS HOT MIX
ASPHALT
• THE MINIMUM INFILTRATION RATE FOR NEWLY PLACED
POROUS ASPHALT SHOULD BE 200 INCHES PER HOUR. USE
ASTM C1701 /C1701M -09 TO TEST INFILTRATION RATES AT
LOCATIONS REPRESENTATIVE OF THE PAVEMENT FINISHED
PRODUCT AT A MAXIMUM RATE OF 5,000 SQUARE FEET PER
TEST.
GEOTEXTILE AND GEOGRIDS
• USE GEOTEXTILE RECOMMENDED BY THE
MANUFACTURER'S SPECIFICATIONS AND
RECOMMENDATIONS OF THE GEOTECHNICAL ENGINEER
FOR THE GIVEN SUBGRADE SOIL TYPE AND BASE
AGGREGATE.
