1. SEE ADJACENT DETAIL.
2. A SEPARATION GEOTEXTILE SHALL BE PLACED UNDER THE SPALLS TO PREVENT FINE SEDIMENT FROM
PUMPING UP INTO THE ROCK PAD. THE GE07EXTILE SHALL MEET THE FOLLOWING STANDARDS.
GRAB TENSILE STRENGTH (ASTM D-4751) .....................200 PSI
GRAB TENSILE ELONGATION (ASTM D-4632) ..................30% MAX.
MULLEN BURST STRENGTH (ASM D -3786-80A) ........... 400 PSI MIN.
AOS (ASTM D-4751)........................................................20-45 (U.S. STANDARD SIEVE SIZE)
J. HOG FUEL MAY BE SUBSTITUTED FOR OR COMBINED WITH QUARRY SPALLS IN AREAS THAT WILL NOT BE
USED FOR PERMANENT ROADS. THE EFFECTIVENESS OF HOG FUEL IS HIGHLY VARIABLE, BUT IT HAS BEEN
USED SUCCESSFULLY ON MANY SITES. IT GENERALLY REQUIRES MORE MAINTENANCE THAT QUARRY SPALLS.
THE INSPECTOR MAY AT ANY TIME REQUIRE THE USE OF QUARRY SPALLS IF THE HOG FUEL 1S NOT
PREVENTING SEDIMENT FROM BEING TRACKED ONTO PAVEMENT OR IF THE HOG FUEL IS BEING CARRIED
ONTO PAVEMENT. HOG FUEL IS PROHIBITED FROM PERMANENT ROADBEDS BECAUSE ORGANICS IN THE
SUB -GRADE SOILS CAUSE DIFFICULTIES WITH COMPACTION.
4. FENCING SHALL BE INSTALLED AS NECESSARY TO RESTRICT TRAFFIC TO THE CONSTRUCTION ENTRANCE.
5. WHENEVER POSSIBLE, THE ENTRANCE SHALL BE CONSTRUCTED ON A FIRM, COMPACTED SUBGRADE THIS
CAN SUBSTANTIALLY INCREASE THE EFFECTIVENESS OF THE PAD AND REDUCE THE NEED FOR MAINTENANCE.
