In flooring construction point of view VDF is The Vacuum Dewatered (VD) Flooring. 
It is a system for laying high quality concrete floors with superior cost-effectiveness.
It is used in industries where flooring subjected to considerable wear and vibrations. 
The key to the use of this method is the dewatering of concrete by vacuum process surplus water from the concrete is removed immediately after placing and vibration, reducing the water cement ratio to an optimum level. 
Therefore, adopting the VD flooring method facilitates use of concrete with better workability than what is normally possible. 
A lowered water to cement ratio due to vacuum dewatering leads to improvement in each of the properties of concrete like high wear resistance high compressive strength, reduced shrinkage, minimum water permeability and should be free of pores. 
In transportation engineering point of view VDF is The Vehicle Damage Factor it is a multiplier for converting the number of commercial vehicles of diff erent axle loads and axle con figurations to the number of standard axle-load repetitions. 
It is de nied as equivalent number of standard axles per commercial vehicle. 
The VDF varies with the axle confi guration, axle loading, terrain, type of road, and from region to region.
