Performance Evaluation of JPCP with Changes of Pavement Mix Design Using Pavement Management Data

Table 3

Grade of pavement performance index of HPCI component for HPMS.

Grade	HPCI	IRI	SD (m^2)	SD (%)	Action
1	4.0 or more	Below 1.5	0	0	Do nothing
2	4.0–3.5	1.5–2.0	Less 1.0	0.3	Preventive maintenance
3	3.5–3.25	2.0–2.5	1.0–18	0.3–5	Maintenance and repair if necessary
4	3.25–3.0	2.5–3.0	18–36	5–10	Maintenance and repair
5	3.0–2.5	3.0–3.5	36–52	10–15	Rehabilitation, if necessary
6	2.5–2.0	3.5–4.0	52–72	15–20	Rehabilitation
7	Below 2.0	4.0 or more	72 or more	20 or more	Preferred rehabilitation

SD (%): unified surface distress per unit area of pavement surface.
