Bituminous mixtures - Test method - Part 33: Specimen prepared by roller compactor

This document specifies the methods for compacting parallelepipedal specimens (slabs) of bituminous mixtures, to be used directly for subsequent testing, or from which test specimens are cut.
For a given mass of bituminous mixture, the specimens are prepared either under controlled compaction energy, or until a specified volume and therefore air voids content is obtained.
This document describes the following methods of compaction:
- method using a wheel or two wheels fitted with pneumatic tyres;
- methods using a steel roller, which includes 3 different procedures:
- steel roller;
- steel roller used on wheel fitted with pneumatic tyres;
- steel roller running on vertical sliding steel plates;
- method using a steel roller sector.
This document is applicable to bituminous mixtures manufactured in the laboratory or in a mixing plant.

Overview

SIST EN 12697-33:2019/oprA1:2022 is a European standard developed by CEN that specifies test methods for preparing specimens of bituminous mixtures using a roller compactor. This standard focuses on the creation of parallelepipedal specimens, commonly referred to as slabs, which can be directly tested or further cut into test specimens. It sets out detailed procedures to achieve consistent compaction either by applying controlled compaction energy or by achieving a specified specimen volume and air void content.

Designed for both laboratory and mixing plant environments, this amendment to EN 12697-33 ensures improved accuracy and reproducibility in the preparation of bituminous mixture specimens. The specified compaction methods include different types of rollers and wheel configurations fitted with pneumatic tyres or steel rollers.

Key Topics

• Specimen Preparation: Guidelines for producing parallelepipedal specimens of bituminous mixtures for testing purposes.
• Compaction Methods:
  • Use of one or two wheels fitted with pneumatic tyres.
  • Steel roller methods with three distinct procedures:
    • Standard steel roller.
    • Steel roller on wheels with pneumatic tyres.
    • Steel roller running on vertical sliding steel plates.
  • Steel roller sector method.
• Compaction Control: Specimens can be compacted based on:
  • A defined compaction energy level.
  • Achieving a predetermined specimen volume and corresponding air void content.
• Load Application: The amendment clarifies the application of static load (F) on wheels or rollers, introducing a formula that includes a roller compaction parameter (W), interior mould width (l), and wheel or roller diameter (D).

Applications

• Road Construction and Maintenance: Enables reliable characterization of bituminous mixtures, essential for pavement performance and durability studies.
• Material Testing Laboratories: Assists labs in preparing standard specimens that reflect field compaction conditions, facilitating quality control and mix design validation.
• Mixing Plants: Provides standardization for specimen preparation to ensure consistency in production quality assessment.
• Research and Development: Offers a precise and repeatable compaction method critical for developing new asphalt formulations and additives.
• Quality Assurance: By standardizing specimen compaction, it supports manufacturers and contractors in meeting technical specifications and regulatory requirements.

Related Standards

• EN 12697 Series: Contains complementary parts covering various test methods for bituminous mixtures, including stiffness, fatigue, moisture susceptibility, and more.
• EN 13108 Series: Specifies requirements for asphalt mixtures, aligning with specimen preparation procedures.
• CEN/TC 227 Standards: Under the umbrella of road material testing, these standards provide comprehensive guidelines on performance evaluation of paving materials.
• ISO 13473: Controls aggregate particle shape and size, relevant for preparing bituminous mixtures according to EN standards.
