1. EXCAVATE TO THE ELEVATION OF THE FREE -DRAINING

2. PREVENT SEDIMENT AND RUNOFF FROM ENTERING BED
DURING CONSTRUCTION.
3. COMPACT UPPER 12" OF EXISTING SUBGRADE SOIL TO
ENSURE 90-92% STANDARD PROCTOR
4. AVOID OVER -COMPACTION BY RESTRICTING ACCESS TO
THE AREA FOR MATERIAL STOCKPILING & HEAVY
CONSTRUCTION VEHICLES
5. FINAL GRADING SHOULD BE COMPLETED BY MACHINERY
OPERATING ON A PRELIMINARY SUBGRADE THAT IS AT
r
LEAST 12 INCHES HIGHER THAN FINAL GRADE OR

STEEL PLATES OR AGGREGATE BASE MATERIAL). FINAL

O
GRADE IS EXCAVATED.
6. TO PREVENT COMPACTION WHEN INSTALLING THE
AGGREGATE BASE, THE FOLLOWING STEPS
U
(BACK -DUMPING) SHOULD BE FOLLOWED: 1) THE
AGGREGATE BASE IS DUMPED ONTO THE SUBGRADE FROM
THE EDGE OF THE INSTALLATION AND AGGREGATE IS THEN
PUSHED OUT ONTO THE SUBGRADE; 2) TRUCKS THEN
DUMP SUBSEQUENT LOADS FROM ON TOP OF THE
AGGREGATE BASE AS THE INSTALLATION PROGRESSES.
7. AVOID SUBGRADE PREPARATION DURING WET PERIODS
(SOIL COMPACTION INCREASES SIGNIFICANTLY IF SOIL IS
WET).
8. IF MACHINERY MUST ACCESS THE FINAL GRADE, LIMIT THE
ACCESS TO A SPECIFIC TRAVEL WAY THAT CAN BE TILLED
BEFORE APPLICATION OF THE BASE AGGREGATE OR
PLACE HEAVY STEEL PLATES ON SUBGRADE AND LIMIT
TRAFFIC TO THE PROTECTIVE COVER.

NOTE: ALLOWING HEAVY MACHINERY ON PERMEABLE

SAND SPECIFICATION:
Q
THE SAND MUST CONSIST OF A MEDIUM SAND MEETING THE
SIZE GRADATION (BY WEIGHT) GIVEN IN TABLE 1. THE
CONTRACTOR MUST OBTAIN A GRAIN SIZE ANALYSIS FROM
THE SUPPLIER TO CERTIFY THAT THE SAND MEETS THE NO.
