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

• Includes potholes, cracking, grass, weeds,
  patching, striping, signs, litter, guardrail,
  shoulders, etc.

37
(p1) Pavement Potholes

• Bowl shaped hole or depression in surface
• Broken into smaller pieces due to cracking or
  localized disintegration

  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
