1. EXCAVATE TO THE ELEVATION OF THE FREE -DRAINING
SAND OR GRAVEL BASE.
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
�--
LEAST 12 INCHES HIGHER THAN FINAL GRADE OR

STEEL PLATES OR AGGREGATE BASE MATERIAL). FINAL
co
EXCAVATION THEN PROCEEDS AS MACHINERY IS PULLING

BACK AND TRAVELING ON PRELIMINARY GRADE AS FINAL
0
GRADE IS EXCAVATED.
6. TO PREVENT COMPACTION WHEN INSTALLING THE
T
AGGREGATE BASE, THE FOLLOWING STEPS
{_)
(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
C0
TRAFFIC TO THE PROTECTIVE COVER.

SAND SPECIFICATION:
THE SAND MUST CONSIST OF A MEDIUM SAND MEETING THE
0
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.
100 AND NO. 200 SIEVE REQUIREMENTS. (NOTE: STANDARD
BACKFILL FOR SAND DRAINS, WA. STD. SPEC. 9-03.13, DOES
NOT MEET THIS SPECIFICATION AND DO NOT USE SPEC
9-03.13 FOR SAND FILTERS.)
