COMPARISON OF UNDERBOLD AND THE CONVENTIONAL METHOD

   

 CONVENTIONAL

 LOCAL ENVIRONMENT Asphalt and other existing contaminants or loads must be disposed of in landfills for a fee

DENSITY Lower density as air pockets become filled with water or remain empty. This causes movement of material particles which in turn causes constant damage to the asphalt sur-face

GLOBAL ENVIRONMENT Due to the longer construction time as well as the extensive logistics, the CO2 impact with the conventional method in the same example is 863,537 kg.

 

 

UNDERBOLD-POD30

LOCAL ENVIRONMENT Asphalt and other existing contaminants or loads are immobilized by the mix in place procedure, eliminating the need to dispose of the old material.

 DENSITY With the UNDERBOLD method, a very high density is achieved, as the air pockets are filled up to the micro-range with the nanoparticles instead of remaining empty, thus causing a stable layer.

 GLOBAL ENVIRONMENT The impact on the environment is significantly reduced with the UNDERBOLD method due to the shorter construction time. Example: For the renovation of a 17km highway, the CO² impact is 37,673 kg 

 With UNDERBOLD-POD30

RESISTANCE TO TEMPERATURE CHANGES  

Due to the high water impermeability, a very high resistance to temperature changes is achieved, with changes between day/night, winter/summer and thus the tendency to crack formation is considerably minimized.

DURATION OF THE CONSTRUCTION PHASE  

With the UNDERBOLD POD30 method about 3-4 times faster than with a conventional method. Example: for 1km of road, 10 meters wide, you need 3-4 days

MATERIAL 

The UNDERBOLD method can be used on all soils as long as the organic content is not too high. In case of rehabilitation, the existing asphalt layers can be incorporated.

BEARING CAPABILITY  

Any desired bearing capacity can be achieved by adjustments in the UNDERBOLD cement mix.

 

 CONVENTIONAL

RESISTANCE TO TEMPERATURE CHANGES  

Very high tendency to crack due to temperature changes due to high water permeability. 

DURATION OF THE CONSTRUCTION PHASE  

Construction time for 1km road, 10 meters width is 10-14 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 bearing capacities are limited depending on the existing soil material. To achieve higher bearing capacities, the thickness of the asphalt layer must be increased.
