GENERAL NOTES (CONTINUE ON SHEET 2)

1. ALL GUARDRAILS SHOWN ARE MASH 2016 TL -3 COMPLIANT.

2. RATE OF SLOPE DEPENDS ON GUARDRAIL LOCATION:

A. FDR GUARDRAIL FACE 2 FT. DR LESS FROM THE NORMAL EDGE OF PAVED SHOULDER,

CONTINUE THE RATE OF SLOPE OF THE NORMAL PAVED SHOULDER TD THE BREAKPOINT.

B. FDR GUARDRAIL FACE MORE THAN 2 FT.FROM THE NORMAL EDGE OF THE PAVED SHOULDER,

THE SLOPE SHALL BE 10:1 DR FLATTER.

3. WHEN SPECIFIED ON THE PLANS, EXTEND A 2 IN. MINIMUM THICKNESS PAVED SURFACE TD 1 FT. BEHIND THE GUARDRAIL POSTS DR TD THE EROSION CONTROL CURB AS SHOWN ON PLANS.

ASPHALT CUTTING & PATCHING DR OTHER APPROVED METHOD SHALL BE USED TO MINIMIZE DAMAGE TD ALL PAVED SURFACES UNDER GUARDRAIL INSTALLATIONS. ALL REPAIRS TD THE PAVED AREA WILL NOT BE MEASURED AND PAID FDR SEPARATELY BUT SHALL BE INCLUDED IN THE COST OF THE WORK. A MINIMUM 3 IN. THICK FIBER REINFORCED CONCRETE PAVEMENT MAY ALSO BE USED FDR PAVING BENEATH THE GUARDRAIL. INSTALL THE POST IN A Y2 IN. OVERSIZED FORMED HOLE FDR GUARDRAIL RUNS AND TERMINALS AS DIRECTED. PAYMENT FDR THIS PAVED SURFACE WILL BE MADE UNDER A PAVEMENT DR CONCRETE PAY ITEM WITH QUANTITIES SHOWN ON THE PLANS.

4. THE MINIMUM GUARDRAIL OFFSET FROM PAVED SHOULDER EDGE SHALL BE:

0 FT.FDR SHOULDERS 8 FT. OR WIDER

2 FT. FDR SHOULDERS 6 FT. DR LESS

THE GUARDRAIL OFFSET FROM PAVED INSIDE SHOULDER EDGE OF A DIVIDED HIGHWAY SHALL BE;

0 FT. MINIMUM FDR SHOULDERS 6 FT. OR WIDER

2 FT.DESIRABLE FDR 4 FT. SHOULDERS

THE ABOVE 2 FT.GUARDRAIL TD SHOULDER OFFSET IS DESIRABLE BUT NOT REQUIRED FDR:

A. FDR AN EXISTING HIGHWAY WITH A DESIGN SPEED LESS THAN 50 MPH, THE MINIMUM OFFSET

IS 4 FT. FROM THE TRAVELED WAY.

B. FDR A ONE-WAY ONE-LANE RAMP, AND WHERE ONE OR MORE OF THE FOLLOWING ARE TRUE:

(I) THE NON-OFFSET GUARDRAIL BEGINS AT LEAST 100 FT. BEYOND RAMP NOSE.

(2) THE NON-OFFSET GUARDRAIL IS NOT LOCATED ON THE RAMP EXIT DR ENTRANCE

CURVE CONNECTION TD THE MAJOR HIGHWAY.

(3) THE RAMP SHOULDERS ARE 4 FT. DR WIDER.

USE OF GREATER THAN MINIMUM OFFSET DIMENSIONS IS ENCOURAGED TD MEET THE DESIRABLE

GOAL OF PLACING THE GUARDRAIL AS FAR AS POSSIBLE FROM THE TRAVEL WAY,EVEN FDR

SHORT DISTANCES, WHILE PROVIDING A SMOOTH CHANGE IN GUARDRAIL ALIGNMENT.

5. IF 2 FT. CANNOT BE PROVIDED BETWEEN THE BACK OF THE GUARDRAIL POST AND THE BREAKPOINT, USE 7 FT. GUARDRAIL POSTS. REFER TD THE "RESTRICTIVE ROADSIDE INST ALLA TIDN" DETAIL.

6. WHEN SPECIFIED ON THE PLANS, INST ALL 4 IN. HIGH TYPE 6 CURB WITH ITS FACE AT DR BEHIND THE RAIL FACE. AS AN ALTERNATIVE WHEN SPECIFIED ON THE PLANS, INST ALL A 2 IN. x 6 IN.

TREATED (AASHTD M 133) WOOD CURB. FASTEN WITH A 4 IN. LAG BOLT AND WASHER AT

EACH WOOD POST, DR WITH A 1#4 IN. DIA. BOLT WITH WASHER AND NUT AT EACH STEEL POST.

IF THE 2 IN. x 6 IN. WOOD CURB IS SPECIFIED, IT WILL BE INCLUDED IN THE COST OF THE GUARDRAIL.

IF APPROVED BY THE ENGINEER,A 2 IN. x 4 IN. TREATED WOOD CURB MAY BE SUBSTITUTED FOR THE 2 IN. x 6 IN. CURB AND SET ON TOP OF PAVEMENT SURFACE AND ATTACHED AS DESCRIBED ABOVE.

ND SPLICING SHALL BE ALLOWED IN WOOD CURBS. ADJACENT BOARDS SHALL BE BUTTED TOGETHER
