NORTH CAROLINA DIVISION OF HIGHWAYSCONCRETE PAVEMENT CONDITION SURVEY

This manual has been developed to assist North Carolina Division of Highways personnel inconducting a condition survey of the concrete pavements in North Carolina. The survey is a 20% samplesurvey. The first .20 mile (CRC) or first 41 slabs (JCP) are rated. The manual is divided into four

sections as follows:

A) GENERAL

1) Shoulder Type Page 22) Shoulder Condition Page 23) Shoulder-Lane Drop-off Page 64) Shoulder-Lane Joint Seal Page 75) Surface Wear Page 96) Pumping Page 107) Ride Quality Page 11

B) JOINTED CONCRETE PAVEMENTS

1) Concrete Patches Page 122) Asphalt Patches Page 123) Longitudinal Cracking Page 134) Transverse Cracking Page 145) Corner Breaks Page 156) Spalling Page 167) Joint Seal Damage Page 178) Faulting Page 18

6) Pumping Number of joints or areas Description: Seeping or ejection of water from beneath the pavement through cracks or joints. Finematerial may be present near joints or cracks staining the surface and there may also be depressions.

7) Ride Quality Percent of area

Description : Ride quality is what the general public perceives as an indicator of howwell a road is performing. The average operating speed is the speed at which mostdrivers would travel a section of road.

L: Operating speed easy to maintain. A few bumps and dips (up to 25% of section). Joints are fairly smooth.

M: Slightly difficult to maintain safe operating speed. Some joints appear to be faulted. Joints or cracks cause bumps and unevenness.

S: Difficult to maintain safe operating speed. Most joints severely faulted.Cracks cause unevenness and surface may be broken, cracked or worn away.

4 ) Transverse Cracking Number of slabs with transverse cracks

Description : Cracks that are predominantly perpendicular to the pavement centerline.

L: Crack widths less than 1/8 inch, no spalling, no faulting

M: Crack widths from 1/8 to 1/2 inch, or with spalling less than 3 inches, or faulting up to 1/4 inch, may be sealed.

S: Crack widths greater than 1/2 inch, or with spalling greater than 3 inches, or faulting greater than 1/4 inch.

5) Corner Breaks Number of slabs with corner breaks Description : A portion of the slab separated by a crack which intersects theadjacent transverse and longitudinal joints, approximately at a 45 degree angle. Thelength of the sides is from 1 ft. to 1/2 the width of the slab, on each side of the corner.

L: Crack well sealed or hairline, no faulting or spalling, no break-up.M: Crack spalled at low to moderate severity, faulting less than 1/2 inch, no pieces

broken.S: Crack spalled at moderate to severe severity, faulting greater than 1/2 inch,

broken into two or more pieces.

7) Joint Seal Damage Number of joints with joint seal damage

Description : Condition which enables materials or water to infiltrate the joint. Also,includes extrusion, hardening, adhesive failure, cohesive failure or complete loss of sealant.

L: Joint seal damage exists in less than 10% of the joint.M: Joint seal damage exists in 10% to 50% of the joint.S: Joint seal damage exists in more than 50% of the joint.

L: Boundary of punchout is well defined but still has good aggregate interlock,cracks are tight and no spalling around boundary.

M: Boundary of punchout is spalled, has faulting and shows signs of movement.S: Loss of material and developing secondary cracks.
