GENERAL NOTES

(1) RATE OF SLOPE DEPENDS ON GUARDRAlL LOCATION:
-FOR GUARDRAIL FACE 2 n. OR LESS FROM THE NORMAL EDGE OF PAvED
SHOULDER. CONTiNUE THE RATE OF SLOPE Of THE NORMAL PAVED SHOULDER
TO THE BREAKPOINT.

-fOR GUARDRAIL rACE MORE l'HAN 2 fT. FROM THE NORMAl EDGE OF THE PAVED
SHOULDER, THE SLOPE SHALL BE 10" OR FLATTER,

(2) wHEN SPECifiED ON THE PLANS. EXTEND A 2 IN~ ~INIMU~ THICKNESS PAVED
SURFACE TO 1 fT, BEHIND THE GUARDRAlL POSTS OR TO THE POSTS. WITH,
EROSiON CONTROL CURB. PAYMENT FOR THIS PAVED SURFACE WILL BE MADE
UNDER A PAVEMENT PAY ITEIo4 WITH QUANTITIES SHOWN ON THE PLANS.

(J) THE MINIMUM GUARDRAIL OFFSET FROU PAVEO SHOULDER EDGE SHALL BE:
0' FOR SHOULDERS 8' OR WIDER
2' FOR SHOULDERS 6' OR LESS

THE ABOVE 2' GUARDRAIL TO SHOULDER OFfSET IS DESIRABLE BUT NOT REOUIRED fOR

1. EXISTING HIGHWAY WITH DESIGN SPEED OF LESS THAN 50 MPH. MINIt.fUM OFFSET
OF RAIL IS O' fRO~ ANY WIDTH PAVED SHOULDER OR l' fRO~ TRAVELED WAY.

2. A ONE -WAY ONE -LANE RAMP AND:

- THE NON-OFFSET CUARDRAIL BEGINS AT lEAST 100' BEYOND RAMP NOSE.

- THE NON-OfFSET GUARDRAIL IS NOT LOCATED ON THE RAMP Exn OR ENTRANCE
CUR~E CONNECTION TO THE MAJOR HIGHWAY.

- THE RAMP SHOULDERS ARE 4' OR WIDER.

USE Of GREATER THAN ~INI~U~ OffSET OI~ENSIONS IS ENCOURAGED TO MEET THE
DESIRABLE GOAl OF PLACING THE GUARDRAIL AS F"AR AS POSSIBLE FROM THE TRAVELED
WAY. EVEN FOR SHORT DISTANCES. WHILE PROVIDING A SMOOTH CHANGE IN GUARDRAIL
ALIGNMENT.

(.) IF 2 FT. CANNOT BE PROVIDED BETWEEN THE BACK OF THE GUARDRAIL POST AND
THE BREAKPOINT. USE 7 n. GuARDRAIL POSTS. REFER TO THE "RESTRICTIVE
ROADSIDE INSTALLATION" DETAIL.

(5) WHEN SPECifiED ON THE PLANS. INSTAlL 4" HIGH TYPE 6 CURB WITH ITS fACE AT OR
BEHIND THE RAlL fACE. PAY fOR AS ITE~ 609, AS AN AlTERNATIVE WHEN SPECIFIED
ON THE PLANS. INSTALL A 2" x 6" (NOMINAL) TREATED (M 133) WOOD CURB WITH
A 4" LAG BOLT AND WASHER AT EACH WOOD POST. OR A 1/4" DIA, BOLT WITH WASHER
AND NUT AT EACH STEEL POST, If THE 2" ,,6" WOOD CURB IS SPECifiED IT WILL BE
INCLUDED IN THE COST OF THE GUARDRAIL.

(6) WHERE A POST ~UST BE O~ITTED IN A GUARDRAlL RUN, SUCH AS AT A PIPE CULvERT
WITH MINIMU~ COVER. THE W-BEAM RAlL SPANNING THE D~ITTED-POST GAP SHAlL BE
DOUBLED (ONE RAlL NESTED IN THE OTHER), If NECESSARY. TWO CONSECUTIVE POSTS
MAY BE OMITTED IN GUARDRAIL WITH 6'-3" SPACEO POSTS. EXTEND THE NESTED RAIL
IN BOTH DIRECTIONS AT lEAST 6'-3" BEYOND THE Ot~lnEO-POST GAP TO A RAIL SPLICE
DEPENDING ON RAIL SPLICE LOCATION, ONE QUlffiO POST REQUIRES EITHER 25' OR
37'-6" OF NESTEO RAIL, AND TWO OMITTED POSTS REQUIRE 37'-6" OF NESTED RAIL
USING 12'-6" LONG RAIL SECTIONS.

(7) WHEN GUARDRAIL IS FLARED AWAY FRQU NORMAL GUARDRAIL AND CURB ALIGNMENT,
SUCH AS THE TYPE 3E END fLARE ON SHEET 5. THE CURB MUST EITHER fLARE WITH
THE GUARDRAlL OR BE ELI~INATED.
