The SGC can be used to design mixtures that do not exhibits classic tender mix behaviour and do not densify to dangerously low air void contents under traffic action.
This percentage was established by looking at the average values for the following four asphalt contents: (1) asphalt binder content corresponding to maximum stability and flow (S/F) ratio; (2) asphalt binder content corresponding to maximum bulk specific gravity; (3) flow values between 2 and 3,5 mm; (4) asphalt binder content corresponding to designed air void percentage boundaries in the total mixture (between 3% and 6%).
Special attention should also be emphasized on the air void level, which should have a lower level to guard against water permeability.

The total volume of these air voids within the concrete is known as the air void content.
In road structure surveys, GPR has been used to measure layer thickness, to detect subsurface defects and to evaluate base course quality, to estimate air void content of asphalt surfaces and to detect mix segregation.
Coating at high speeds requires low air void volume in the coating color and viscosity control.
demonstrates that tungsten metal can be used not only as a mask for epitaxial lateral overgrowth but also for the formation of an air void underneath it to improve both internal quantum efficiency and extraction efficiency of the LEDs.
Marshall stability, flow, Marshall quotient, maximum density, air void content, voids filled with bitumen (VFB), voids in mineral aggregate (VMA) were investigated.
