2. SUPERELEVATIONS ARE SHOWN ON THE SUPERELEVATION DIAGRAMS.
3. EXACT LOCATIONS AND TYPES OF DIKE, CONCRETE BARRIER, AND METAL BEAM
GUARDRAIL ARE SHOWN ON THE LAYOUTS. EXACT LIMITS OF PROPOSED
STRUCTURAL SECTIONS ARE SHOWN ON THE LAYOUTS.
4. PRIOR TO PLACEMENT OF NEW CONCRETE PAVEMENT, GRIND EDGE OF EXISTING
CONCRETE PAVEMENT WHERE IT INTERFACES WITH NEW CONCRETE PAVEMENT A
I.AINIMUM WIDTH OF 3 FEET.
5. FOR LOCATION AND DE TAILS OF RETAINING WALLS AND SOUNDWALLS, SEE

9. AREAS OF UNSUITABLE MATERIAL ARE DEFINED AS HAVING A R VALUE LESS
THAN 10 AND A PI GREATER THAN 12 WITH IN LIMITS OF ROADWAY EXCAVATION.
10. FOR OVEREXCAVATION LIMITS SHOWN IN TYPICAL SECTIONS, EXCAVATE 4' BELOW
FINAL FINISHED GRADE UNDER THE ENTIRE WIDTH OF PROPOSED PAVEMENT AND
REPLACE TO THE GRADING PLANE WITH SOIL THAT HAS A MINIMUM R VALUE OF
25 AND A PI LESS THAN OR EQUAL TO 12.
11. UNSUITABLE MATERIAL MAY BE PLACED AS EMBANKMENT , BUT SHALL NOT BE
PLACED WITHIN 4 FEET OF FINAL FINISHED GRADE BELOW NEW PAVEMENT .
12. IF UNSUITABLE MATERIAL IS ENCOUNTERED AT THE PAVEMENT SUBGRADE LEVEL
BENEATH PROPOSED PAVEMENT OUTSIDE OF THE LI MITS INDICATED ON THE
PLANS, THE RESIDENT ENGINEER MAY DIRECT THE CONTRACTOR TO REMOVE AND
REPLACE AS DESCRIBED IN NOTE 10 ABOVE.
13. IN LOCATIONS WHERE TRAFFIC STAGING PLANS REQUIRE THE USE OF HIGH EARLY
PCC FOR THE JPCP SURFACE LAYER, THE 0.25'HMA LAYER IN JPCP STRUCTURAL
SECTIONS 1, 2, 3, AND 4 MAY BE REPLACED BY POLYETHELENE SHEETING BONO
