Durability Assessment of Lightweight Cellular Concrete in Subgrade by the Method of Analytic Hierarchy Process Combined with Fuzzy Comprehensive Evaluation

Table 3

Grade classification of influencing factors of operation and management.

Assessment grade	Curing time (day)	Vehicle load	Drainage condition	Chemical corrosion (%)	Temperature change
Excellent	[10, ∞)	No overload	Excellent	[0, 1)	Minimal
Good	[8, 10)	Very little overload	Good	[1, 3)	Quite small
General	[7, 8)	A small amount of overload	General	[3, 10)	Large
Poor	(0, 7)	A lot of overloads	Poor	[10, ∞)	Quite large
