Settlement ** C C C N N C
Patch deterioration C C C C C C Possible causes of roughness: Poor load transfer, loss of support, subbase pumping, backfill settlement, freeze thaw and moisture related settlement/heave, curling and warping and poor construction practices.
Surface Polishing N C N N P N Possible causes of surface polishing: High volumes of traffic, poor surface texture, wide uniform tine spacing, wide joint reservoirs, and wheel path abrasion because of studded tires or chains.

Surface Defects
Scaling N N C C P P
Popouts N N C C P C
Crazing N N N C C P
Plastic shrinkage cracks N N N C C P Possible causes of surface defects: Over-finishing the surface, poor concrete mixture, reactive aggregates, and poor curing practices.
* P= Primary Factor C= Contributing Factor N= Negligible Factor ** Loss of support is an intermediary phase between the contributing factors and these distresses. Loss of support is affected by load, water and design factors.

Blow-ups C N N P C N
Joint Seal Damage ** C C C C P C Possible causes of joint/crack deterioration: Incompressibles in joint/crack, material durability problems, subbase pumping, dowel socketing or corrosion, keyway failure, metal or plastic inserts, rupture and corrosion of steel in JRCP, high reinforcing steel.
