EN 12697-10:2017 (E) 3 European foreword This document (EN 12697-10:2017) has been prepared by Technical Committee CEN/TC 227 “Road materials”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2018, and conflicting national standards shall be withdrawn at the latest by June 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12697-10:2001. The following is a list of significant technical changes since the previous edition: — the series title no longer makes the method exclusively for hot mix asphalt; — Terms and definitions deleted, [3.1] to [3.10]; — definition of compactability and compaction resistance have been added, [3.1]and [3.2]; — [6.2] 2nd paragraph. "At least three tests shall be carried out on each mixture"; amended to: "At least three specimens shall be compacted on each mixture"; — more detailed explanation of regression analysis for impact compaction method [7.1.2]; — change of regression procedure for impact compaction procedure by considering only thickness measurements between impact 30 and 200 in reduce effect of manual mould filling [Figure 2]; — “force” added in Clause 8, List Entry e). The applicability of this European Standard is described in the product standards for bituminous materials. A list of all parts in the EN 12697 series can be found on the CEN website. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 12697-10:2017 (E) 4 1 Scope This European Standard describes three test methods for characterizing the compactability of a bituminous mix, by the relation between its density or void content and the compaction energy applied to it, using an impact (Marshall) compactor, gyratory compactor, or a vibratory compactor. This European Standard applies to bituminous mixtures, both those prepared in laboratory and those resulting sampled from plant produced mixtures. The results of the test method serve to supplement the results of mixture design. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

EN 12697-10:2017 (E) 5 Note 1 to entry: High values of C and T will indicate a mixture for which high compaction energy is required to obtain a given void content decrease. 4 Principle The bituminous mixture is compacted at a prescribed temperature with varying compaction energies using one of three optional types of compaction methods: a) impact compaction b) gyratory compaction c) vibratory compaction. Two methods of monitoring the compactability can be applied: — Method 1: two or more specimen are compacted with different amounts of compaction energy and their densities are measured. — Method 2: one specimen is used and its increase in density during the compaction process is determined from its decrease in thickness. The following Table 1 defines the compaction type to use depending of the compactness of tracking method and gives the clause of test procedure. Table 1 — Compaction type
Procedure clause according to compaction method impact gyratory vibratory Compaction of specimens with varied compaction energy 6.1.1 n. a. 6.3 Measurement of specimen thickness during compaction 6.1.2 6.2 n. a. A graph is drawn of density (or voids content) against compaction energy. When the impact compaction is used, the compaction energy is characterized by the number of blows, when the gyratory compaction is used, by the number of gyrations and when the vibratory compactor is used, by the duration in seconds. A mathematical formula is derived from the experimental results, the parameters of which formula characterize the compactability of the bituminous mixture. 5 Apparatus 5.1 Impact compaction 5.1.1 Marshall compactor in accordance with EN 12697-30. 5.1.2 Measuring device for automatically recording the thickness of the specimen after each blow of compaction wit
