Rutting Model for HMA Overlay Treatment of Composite Pavements

Table 1

Ranking of overlay treatment based on dominant distress types occurring after application of each of the treatments (a ranking of 1 is the most dominant distress type).

Treatment type	PH	BL	CR	RV	FC	TC	LC	RT	FT	CB
Structural overlay (>2 in)	5.0	8.5	4.7	4.7	3.8	2.3	2.5	2.5	8.5	9.5
Nonstructural overlay (≤2 in)	4.0	8.5	4.7	3.7	3.0	2.3	3.0	2.3	8.5	9.5

PH: potholes; BL: bleeding; CR: corrugation; RV: raveling; FC: fatigue cracking; TC: transverse cracking; LC: longitudinal cracking; RT: rutting; FC: faulting; CB: corner break.
