Load Transfer Efficiency Analysis and Void Evaluation of Composite Pavement Cement Concrete Slab

Table 6

Deflection values of loaded and nonloaded cement concrete slabs under different void characteristics.

Void degree	Void size/m	Semivoid at slab corner				Full void of slab corner
		Loading slab/0.01 mm	Nonloaded slab/0.01 mm	Deflection difference/0.01 mm	Deflection load transfer coefficient%	Loading slab/0.01 mm	Nonloaded slab/0.01 mm	Deflection difference/0.01 mm	Deflection load transfer coefficient%
