Roadway Sampling
  • Between 300 and 400 roadway segments per district
  • Sample four road types Interstates, Other NHS,
    Other SP SS, Rural Secondary
  • Randomly selected

9
MRP Format
  • Once a year main data collection June-September
  • Option to perform retroreflectivity Feb/March
  • Yes/No inspection forms

10
Necessary Equipment
  • Clipboard and pencils
  • MRP inspection forms
  • Rolling wheel measure
  • Upside down spray paint cans
  • Rut measuring rod
  • Ruler (6 or longer)
  • Reflectometer for striping (if possible)
  • Traffic paddles
  • Safety vest for each inspection team member
  • DMI equipped vehicle with flashing lights
  • Route log

11
Procedure
  • Each roadway section is 500 feet
  • Sections should be free of bridges,
    intersections, or construction zones. If not,
    team should move forward to first clear section.
    Sections should be skipped if first clear zone
    reaches another section.
  • Be aware of safety

12
Procedure Contd
  • Mark beginning mile point with paint and every
    100 feet
  • Inspect both sides of the roadway section unless
    noted (usually Interstates and Parkways)
  • Always mark 0 when there is no measure to be
    recorded. Do not leave blanks, mark with dashes
    or NA.

13
(r1) General Aesthetics
  • General appearance of roadway and roadside
  • Includes potholes, cracking, grass, weeds,
    patching, striping, signs, litter, guardrail,
    shoulders, etc.
  • 1Excellent
  • 2Good
  • 3Acceptable
  • 4Poor
  • 5Unacceptable

(r2) Roadway/Shoulder Obstructions
  • Is there roadway or shoulder with less than 15
    vertical clearance?
  • Should be free of canopy (tree or other
    vegetation) or other obstructions for minimum
    height of 15

29
(r3) Visual Obstructions
  • Are there visual obstructions of intersections,
    curves or signs, etc.?

30
(r4) Right of Way Fence
  • Is there right of way fencing?

31
(r5) Fence Not Providing Barrier
  • Is there fence not providing a positive barrier?
  • Fences should deny access to roadways
  • Check for breaks, holes, rusting out, downed
    fence, or missing fence
  • Covered in vines may still be effective

32
(r6) Guardrail
  • Is there guardrail?

33
(r7) Guardrail Outside Specification
  • Is there guardrail outside height specifications
    (25 to 29)?
  • Measured with respect to near edge of road or
    shoulder
  • Outdated end treatments do not count

34
(r8)Guardrail With Damage
  • Is there guardrail with post or accident damage?
  • Due to vehicular hits or other factors
  • Structural integrity or functionality is lost

35
(r9) Guardrail Attenuators/Rail Ends
  • Count and record the total number of
    attenuators/end treatments
  • Include guardrail radius as end treatment

36
(r10) Damaged Attenuators/Rail Ends
  • Count and record the total number of
    attenuators/rail ends that are damaged
  • Due to vehicular hits or other factors
  • Structural integrity or functionality lost

37
(p1) Pavement Potholes
  • Bowl shaped hole or depression in surface
  • Broken into smaller pieces due to cracking or
    localized disintegration
  • Count each pothole that measure 6x6x1 or
    larger
  • Record 20 as max

38
(p2)(p3) Rutting
  • (p2)Outside wheel path at 0 feet
  • (p3) Outside wheel path at 100 feet
  • Surface depression of pavement in wheel path
  • Lay straight edge across wheel path and measure
    rut depth
  • Circle closest measurement

39
(s1) Pavement Drop Off to Shoulder
  • Is there pavement drop off to shoulder greater
    than or equal to 1.5?
  • Decrease in elevation between traffic lane and
    shoulder or absence of shoulder

40
(s1) Pavement Drop Off to Shoulder Contd
  • Consolidation, displacement, settlement
  • Measure about 6 from edge of driving lane

41
(s2) Shoulder Drop Off to Ground
  • Is there shoulder drop off to ground greater than
    or equal to 3.0?
  • Elevation decrease between improved shoulder and
    adjacent ground at outside edge of shoulder
  • Due to consolidation, erosion or run-off
  • Measure at edge of shoulder

42
(s3) High Shoulder
  • Is there high shoulder?
  • Opposite of pavement drop off to shoulder
  • Due to frost heave, swelling soils, unmowed grass
  • Creates ponding of water on pavement

43
(s3) High Shoulder Contd
44
(s4) Shoulder Potholes
  • Bowl shaped hole or depression in surface
  • Broken into smaller pieces due to cracking or
    localized disintegration
  • Count each pothole that measure 6x6x1 or
    larger
  • Record 20 as max

45
(d1) Drainage Structures
  • Count and record the number of drainage
    structures
  • Do not count entrance pipes
  • Do not count edge drains

46
(d2) Drainage Structures Inhibited
  • Count and record the number of drainage
    structures with 25 or greater flow inhibited

    direction
  • No bolts or rivets missing
  • No sign face turned more than 45 from the line of
    sight of traffic flow
