R4U operates a specialized team of experienced technicians who conduct field tests to verify and ensure the highest quality of our road infrastructure projects. Our testing activities are a crucial part of the investment process, guaranteeing compliance with technical standards and ensuring investor satisfaction.

Comprehensive Scope of Field Testing

Our mobile laboratory is equipped with modern measuring instruments, allowing for a wide range of tests to be performed directly on the construction site. We focus on key aspects of construction, including:

• Subgrade and Sub-base Bearing Capacity Tests: We perform dynamic and static bearing capacity tests of the ground, sub-base layers, and cement stabilization. We use specialized equipment, such as the dynamic plate VSS and the DPL penetrometer, which enable fast and precise assessment of technical parameters.

• Soil and Pavement Compaction Tests: We control the degree of compaction for embankments, sub-base layers, and asphalt mixes. This ensures the durability and stability of the entire road structure.

• Bituminous Pavement Tests: We analyze the quality and parameters of asphalt pavements, including their thickness, impermeability, and composition. We also perform tests on the placed asphalt to verify its physical properties after installation.

• Concrete and Cement Mix Tests: We conduct quality tests on concrete and stabilizing mixes, checking their compressive strength and other key properties.

• Geodetic Measurements: We verify the geometric compliance of the constructed infrastructure elements with the design, including the transverse and longitudinal slopes of the pavement.

The Importance of Laboratory Testing for Road Projects

Field and laboratory tests are the foundation upon which the safety and durability of every road investment are built. Regular quality control during construction allows for the early detection of any non-conformities, which minimizes the risk of future problems and costly repairs.

Thanks to our services, clients can be confident that all materials and construction processes meet rigorous standards. Our test reports provide objective documentation that confirms the quality of the work performed and is essential for the technical acceptance of the investment.

R4U's testing services are a key element of the comprehensive support we offer in the road sector, from the design stage to final project acceptance.
