Summary of structural calculation and checking results of cement stabilized macadam base asphalt pavement.

Design deflection value (0.01 mm)	Computed-deflection values (0.01 mm)	Structure layer appellation	Allowable tensile stress (MPa)	Bottom tensile stress (MPa)
21.7	21.1	Coarse-graded bituminous concrete (8 cm)	0.21	−0.0561
		Cement-stabilized macadam (18 cm)	0.23	0.1377
		Cement-stabilized gravel mixed with crushed stone (32 cm)	0.18	0.126
