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.

— Verfahren mit einem Stahlwalzensegment.
Dieses Dokument gilt für Asphalte, die im Labor oder im Asphaltwerk hergestellt wurden.
Mélanges bitumineux - Méthodes d'essai - Partie 33 : Préparation de corps d'épreuve au compacteur de plaque
Ce document spécifie les méthodes de compactage des éprouvettes parallélépipédiques (plaques) de mélanges bitumineux, qui doivent être utilisées directement pour des essais ultérieurs ou à partir desquelles des éprouvettes sont prélevées.
Pour une masse donnée de mélange bitumineux, les éprouvettes peuvent être préparées soit à une énergie de compactage contrôlée, soit à volume spécifié, et par conséquent une teneur en vides d’air est obtenue.
Ce document décrit les méthodes de compactage suivantes :
— méthode utilisant une ou deux roues équipées de pneumatiques,
— méthode utilisant un rouleau en acier, qui comprend 3 procédures différentes :
— rouleau en acier ;
— rouleau en acier monté sur une roue équipée de pneumatiques ;
— rouleau en acier se déplaçant sur des couteaux en acier verticaux ;
— méthode utilisant une portion de rouleau en acier
Ce document s’applique aux mélanges bitumineux fabriqués en laboratoire ou en centrale d’enrobage.
Bitumenske zmesi - Preskusne metode - 33. del: Preskušanci, pripravljeni z valjastim zgoščevalnikom
Ta evropski standard določa metode za zgoščevanje paralelepipednih preskušancev (plošč) iz bitumenskih zmesi, ki se uporabljajo neposredno za nadaljnje preskušanje ali iz katerih se izrežejo preskušanci.
Pri določeni masi bitumenske zmesi se preskušanci pripravijo z regulirano zgoščevalno energijo, ali dokler ni dosežena določena prostornina in posledično vsebnost zračnih votlin.
Ta evropski standard opisuje naslednje metode zgoščevanja:
– metoda s pnevmatikami;
– metoda z jeklenimi valji;
– metoda s predeli jeklenih valjev.
Ta evropski standard se uporablja za bitumenske zmesi, izdelane v laboratoriju ali obratu za mešanje.

including order of execution, and extent of lateral translation 4 Principle A given mass of bituminous mixture is compacted in a rectangular mould under a load applied by a smooth steel roller or its sector or equivalent, or by one or more wheel(s) fitted with pneumatic tyres. The smooth steel roller may run directly on the bituminous mixture, or on a number of vertical sliding plates, which apply a kneading action to the mixture. The wheel(s) or roller performs passes at constant velocity, according to a specified sweep plan if applicable. 5 Apparatus 5.1 Method using a wheel or two wheels fitted with pneumatic tyres 5.1.1 One or more moulds with specified interior dimensions ± 2 mm. Usual dimensions are: — L = 500 mm, l = 180 mm, h = 100 mm or h = 50 mm, or — L = 600 mm, l = 400 mm, h = 150 mm or h = 200 mm. For moulds 600 mm × 400 mm × 150 mm or 600 mm × 400 mm × 200 mm, dimensions are those of the upper part. In order to facilitate demoulding, moulds may have the shape of a truncated pyramid within the interior dimension ranges specified in order to release the specimen. Other dimensions may be used, according to the requirements of specific test methods. 5.1.2 A device to compact the bituminous mixture which shall: — enable application of an adjustable load, F, in range 1 kN ± 10 % to 10 kN ± 5 %, onto the wheel(s); — comprise of one or more wheels equipped with threadless tyres of 400 m 8 size; — enable translation of the rolling load at constant velocity, Vt ± 10 %; — comprise a system for positioning wheel(s) along the different axes of compaction according to predetermined set values for (a ± 20 mm); — enable operation in blocked axis and freed axis modes; — comprise a system capable of periodically bringing the surface flush with the upper edge of the mould during compaction; — one or more blocks of a suitable size (only required if the required thickness of the slab, e, is less than the height of the mould, h). SIST EN 12697-33:2019
When the method is used to prepare slabs at a specified volume or air voids content, a vibrating roller or table may also be used. The device shall enable application of a static load, F, such as: F
· l × 2 × D × 10 «5 (1) where F is the load, applied onto wheels or rollers, in newtons (N); l is the interior width of mould, in millimetres (mm); D is the diameter of the wheel(s) or roller, in millimetre (mm). The diameter of the steel roller, D, shall be in the range 350 mm to 1 100 mm. When the method is used to prepare slabs at a specified volume or air voids content, for a mass as specified in 6.1, the width of the steel roller, b, shall be greater than: — the internal width of the mould, l, if the roller compactor is not equipped so that compaction stops when the desired height of the slab is reached, or — the internal width of the mould, l, minus 8 mm if the roller compactor is equipped so that compaction stops when the desired height of the slab is reached. The load, F, shall be of such magnitude that the specified volume or air voids content is achieved at a number of roller passes between 10 and 50. When the method is used to prepare slabs under controlled compaction energy, the width of the steel roller shall be equal to the interior width of the mould minus (10 ± 5) mm. 5.2.2 Steel roller used on wheel fitted with pneumatic tyres 5.2.2.1 One or more moulds as specified in 5.1.1. 5.2.2.2 A device to compact the bituminous mixture which shall conform to the device in 5.1.2 and comprise, if required, a smooth metal cylinder of diameter, D 400 mm to 800 mm, thickness between 4 mm and 8 mm, and width equal to the interior width of the mould minus (5 ± 2) mm.
