COMPARISON OF
UNDERBOLD POD30 TECHNOLOGY
AND
CONVENTIONAL METHOD
UNDERBOLD-POD30
CONVENTIONAL
LOCAL ENVIRONMENT
Asphalt and other existing contaminants or loads are immobilised, eliminating the need to dispose of the old material.
DENSITY
The UNDERBOLD-POD30 method achieves a very high density, as the air pockets are filled with nanoparticles down to the micro-range instead of remaining empty, thus creating a stable layer.
GLOBAL ENVIRONMENT
The impact on the environment is significantly reduced with the UNDERBOLD-POD30 method due to the shorter construction time.
LOCAL ENVIRONMENT
Asphalt and other existing contaminants or pollutants must be disposed of in landfills for a fee
DENSITY
Lower density as the air pockets are filled with water or remain empty. This causes movement of the material particles which in turn leads to constant damage to the asphalt surface.
GLOBAL ENVIRONMENT
Due to the longer construction time and extensive logistics, the CO2 impact is significantly higher.
RESISTANCE TO TEMPERATURE CHANGES
Due to the high water impermeability, a very high resistance to temperature influences is achieved when changing between day/night, winter/summer and thus the tendency to crack formation is considerably minimised
DURATION OF THE CONSTRUCTION PHASE
With the UNDERBOLD-POD30 method approx. 4-5 times faster than with a conventional method. Example: For 1km of road,
10 metres wide, takes 2 days
MATERIAL
The UNDERBOLD-POD30 method can be used on all soils as long as the organic content is not too high. The existing asphalt layers can also be worked in during renovation work
LOAD-BEARING CAPACITY
Any desired load-bearing capacity can be achieved by making adjustments to the UNDERBOLD-POD30 cement mix.
RESISTANCE TO TEMPERATURE CHANGES
Very high tendency to crack due to temperature changes as there is a high water permeability.
DURATION OF THE CONSTRUCTION PHASE
Construction time for 1 km of road, 10 metres wide is 10 days (binder course, base course)
MATERIAL
Existing soil/asphalt layers must be removed and disposed of at cost. New material must be procured
LOAD-BEARING CAPACITY
Achievable load-bearing capacities are limited depending on the existing soil material. In order to achieve higher load-bearing capacities, the thickness of the asphalt layer must be increased.
