NOTE: IN THOSE AREAS WHERE THE EXISTING ROAD, AFTER

RECONDITIONING IS WIDER THAN THE DESIGNED WIDTH OF

AGGREGATE, CENTER THE LIFT OF AGGREGATE ON ROAD

SURFACE AND FEATHER TO EXISTING SHOULDERS. WHEN

PLACING THE ADDITIONAL XXXX WIDTH OF AGGREGATE IN

NOTE: OUTSLOPED ROADS SHOULD BE USED WHEN ROAD

GRADES ARE GENTLE TO MODERATE (0% TO 8%) AND WHERE

CUTSLOPES ARE DRY. OUTSLOPED ROADS SHOULD BE

CONSTRUCTED WITH ROLLING DIPS FOR DRAINAGE. THERE

SHOULD BE NO DITCH ON THE INBOARD SIDE OF THE

OUTSLOPED ROAD.

NOTE: INSLOPED ROADS SHOULD BE USED WHEN ROAD

GRADES ARE MODERATE TO STEEP (6% AND UP) AND WHERE

TERRAIN MAY BE STEEP OR SLIPPERY. INSLOPED ROADS

ARE ALSO IDEAL FOR HIGHLY ERODIBLE AREAS. EXTRA

ATTENTION SHOULD BE PAID TO ESTABLISHING DITCHES AND

DRAINAGE FOR INSLOPED ROADS.
