Overview

The EN 13863-6:2024 is a European standard developed by CEN that specifies a precise test method for determining the tensile strength of concrete on cylindrical discs used in concrete pavements. This standard defines procedures for preparing test specimens-either manufactured separately or extracted from cores of finished pavements-and outlines the equipment, testing procedure, and calculation of tensile strength. The test method is critical for assessing the durability and structural performance of concrete pavements, ensuring safety and quality in road construction materials.

Published in March 2024, this standard contributes to the EN 13863 series on concrete pavement testing and focuses specifically on uniaxial radial loading to measure tensile strength until concrete failure. It applies broadly within European countries and is set to be adopted as a national standard in member countries by September 2024.

Key Topics

• Test Method Scope: Defines tensile strength determination on cylindrical concrete discs with diameters around 100 mm and height-to-diameter ratios near 0.5.
• Test Specimen Preparation:
  • Specimens can be cast cylinders sliced into discs or cores drilled from existing pavements.
  • Preparation includes sawing, grinding, and storage under controlled temperatures and humidity.
• Apparatus and Equipment:
  • Cylindrical steel moulds for specimen casting.
  • Precision load testing machines (minimum 100 kN capacity).
  • Special test devices with concave hardened steel bearing strips and felt intermediate strips to apply radial force.
• Testing Procedure:
  • Controlled uniaxial radial compressive force applied at a constant rate until specimen failure.
  • Careful alignment and centering of specimens during testing.
• Calculation and Interpretation:
  • Tensile strength calculated using maximum load with established formula.
  • Results reported to 0.01 MPa precision.
• Precision and Reliability:
  • Repeatability and reproducibility data with coefficients of variation between 6.2% and 8.9% depending on specimen type.
• Reporting Requirements:
  • Detailed information on specimen dimensions, preparation, failure load, fracture pattern, and testing conditions must be documented to ensure quality and traceability.

Applications

EN 13863-6:2024 is essential for professionals in the fields of:

• Road construction and maintenance who need to evaluate concrete pavement tensile strength as a measure of performance and longevity.
• Materials testing laboratories providing certification and quality control for concrete pavements.
• Civil engineers and designers employing tensile strength data to validate structural pavement designs.
• Infrastructure project managers ensuring compliance with European standards for concrete materials.
• Research organizations studying concrete behavior under stress conditions typical for pavement applications.

By standardizing tensile strength testing on cylindrical discs, this method enables consistent evaluation and comparison of concrete pavement materials, supporting safer, longer-lasting road surfaces.

Related Standards

EN 13863-6:2024 is part of a comprehensive suite of standards focused on concrete pavement testing:

• EN 13863-1: Test method for determining pavement thickness by survey.
• EN 13863-2: Determination of bond strength between pavement layers.
• EN 13863-3: Measuring pavement thickness from cores.
• EN 13863-4: Wear resistance testing against studded tires.
• EN 13863-5: Determination of dowel bond stress in concrete pavements.

Additionally, normative references relevant to this test method include:

• EN 12390-1: Specifications for concrete specimen shape and dimensions.
• EN 12390-2: Procedures for making and curing concrete specimens.
• EN 12390-4: Testing machines requirements for compressive strength.
• EN 12390-7: Measurement of hardened concrete density.

These standards collectively provide a framework for comprehensive testing and quality assurance of concrete pavements across Europe.
