Q:Cushion, waterproof layer construction to do what information

2, bedding (bed course) refers to the structure below the grass-roots level. Its main role is to water, drainage, antifreeze to improve the grass-roots and soil-based working conditions, the water stability requirements are better. The cushion layer is a structural layer between the base layer and the soil base. When the soil quality is poor, it is used to improve the water stability of the soil base, improve the water stability and frost resistance of the pavement structure and disperse Load to reduce soil deformation.

Q:When the cushion is used, the thickness of the protective layer is not less than ()

Not on the roof: the general waterproof layer above can be used 15 ~ 25mm cement mortar protection.
