for you and assist you with quality assurance?
Asphalt tests
Asphalt is a highly versatile construction material. It possesses nearly ideal properties that make it ideally suited for road construction as well as for bridge, building,
and hydraulic engineering:
Asphalt is versatile, flexible, environmentally friendly, and, when properly processed, reusable.
For over 50 years, as a recognized testing laboratory under RAP STRA 15, we have specialized in road construction testing in accordance with applicable technical regulations and standards.
Our range of services includes, among other things:
- Routine inspections and additional inspections
- Arbitration investigations
- In-house monitoring
Performance-oriented tests such as:
- Behavior of asphalt at low temperatures using uniaxial tensile and cooling tests
- Fatigue resistance using the uniaxial tensile-compression test
- Deformation behavior using the compression-compression test for rolled asphalt
- Deformation behavior using the static and dynamic stamp penetration test for mastic asphalt
- Stiffness and fatigue behavior using the split-tensile-compression test
- Affinity using uniaxial tensile tests and split-tensile tests
Tests of Surface Properties:
- Flatness and skid resistance of roadways
- Radiometric density measurement
- Photometric properties of roadway surfaces and aggregates
- Calculated design using PADESTO
- Testing of thin layers in hot and cold construction methods (DSH, DSH-V, and DSK)
Our range of services is continuously adapted to comply with current European standards and the technical regulations of the FGSV.
The tests listed above represent a selection of the services we offer. If the test you require is not listed, please feel free to contact us.
Bitumen Tests
Testing of road construction bitumen, polymer-modified bitumen, and other bitumen-based binders in accordance with the applicable current European standards as well as the FGSV’s Technical Delivery Conditions and Technical Test Specifications.
For road construction bitumen and ready-to-use polymer-modified bitumen, TL Bitumen-StB 25 is particularly applicable. For bitumen emulsions, TL BE-StB 15 continues to apply; other special and modified binders are tested in accordance with the relevant regulations.
Binders and Types of Binders:
- Road-construction bitumen
- Polymer-modified binders
- Viscosity-modifying bitumen in accordance with TL VBit-StB 22
- Bitumen emulsions
- Special binders and bitumen-based preparations in accordance with TL Sbit-StB 15
Conventional tests:
- Needle penetration
- Ring-and-ball softening point
- Flash point
- Solubility
- Paraffin content
- Fraaß breaking point
- Elastic recovery
- Dynamic and kinematic viscosity
Performance and Rheological Tests:
The current TL Bitumen-StB 25 places greater emphasis on rheological properties in addition to the requirements of European product standards. The current TP Bitumen-StB guidelines are also taken into account.
- Dynamic Shear Rheometer (DSR)
- Bending Beam Rheometer (BBR)
- Force-Ductility (KD)
- Short-Term Laboratory Aging (RTFOT Aging)
- Long-Term Laboratory Aging (PAV Aging)
- MSCR Test (Multiple Stress Creep and Recovery Test)
- DSR Tests for Rheological Characterization and Bitumen Typing (BTSV)
- Determination of rheological properties across the relevant temperature range
The tests listed above represent a selection of our services. If the test you require is not listed, please feel free to contact us.
Road Marking
Inspections
The asphalt-labor is accredited by the “BASt” as a testing laboratory for measuring traffic-related and other properties of road markings in accordance with ZTV M 13, Levels 1 and 2.
We test road markings—both new and used—on completed projects as well as during the application process, in accordance with the applicable current regulations. Our testing is based in particular on ZTV M 13, TL M 23, and TP M 2024, as well as the relevant European standards, specifically DIN EN 1436 and DIN EN 12802.
Inspections and self-monitoring checks during application:
- Overrollability (drying time)
Geometry - Excess height, milling depth, width, and length
- Distribution and embedding of the top-coating material
- Visual assessment of the marking surface
- Verification of application conditions and the marking materials used
On the finished marking:
- Geometry
- Daytime visibility
- Nighttime visibility, dry conditions
- Nighttime visibility in wet conditions (Type II markings only)
- Traction
- Wear resistance (only before the warranty expires)
- Testing for compliance of the marking and construction materials used
in accordance with DIN EN 12802 - Additional verification tests
- Arbitration tests
The tests listed above represent a selection of our services. If the test you require is not listed, please feel free to contact us.
Condition Assessment &
Maintenance Planning
Through a meticulous on-site assessment of the condition—including the documentation of damage characteristics—as well as targeted laboratory analyses of samples taken during demolition, we develop detailed renovation proposals for you, including
possible alternative options.
Scope of Services:
- Flatness measurements in the longitudinal and transverse directions in accordance with TP Eben
- Coating thickness determination in accordance with the applicable technical testing specifications
- Tread pattern measurements using the lateral force measurement method (SKM) in accordance with TP Griff-StB (SKM)
- Skid resistance and, where applicable, roughness measurements using a pendulum device and flow meter in accordance with TP Griff-StB (SRT)
- Transverse profile measurements using a standard transverse profilograph (SQM)
- Non-destructive or minimally destructive density determination using radiometric measurement methods
- Visual condition assessment and evaluation of pavement surfaces
- Determination or computational estimation of the remaining service life of asphalt pavements
- Design of road structures in accordance with RSto and RDO
- Development of rehabilitation proposals, including possible alternative options
The investigations listed above represent a selection of our services. The specific scope of the investigation is tailored to the construction method, the condition of the structure, the project requirements, and the applicable regulations. Based on this, we are happy to develop customized proposals for maintenance, repair, or reconstruction.
