Built-in layer
After installation, the finished layer will be checked for its density, layer thickness, and compaction. These parameters are crucial for load-bearing capacity, service life, and acoustic performance.
Core drill analyses:
Core samples provide information about:
- Layer thickness and uniform execution, within target values.
- Bulk density and void content
- Degree of compaction in relation to the laboratory value
Non-destructive testing methods on the construction site
Supplementary non-destructive methods are available for monitoring construction processes. Their main purpose lies in ongoing process monitoring and fine-tuning during installation. They provide the site manager with direct feedback on the achieved compaction, thereby supporting uniform installation quality.
-
Electromagnetic probes (PQI): Measurement of density via electrical impedance.
-
Radiometric probes (Troxler): Measurement via gamma backscatter.
The application requires experienced and trained personnel to ensure accurate measurements and reliable interpretation of results. The responsibility for compliance with target values and correct process management lies with the executing construction company.
