Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies

(ISO member bodies). The work of preparing International Standards is normally carried out through ISO

technical committees. Each member body interested in a subject for which a technical committee has been

established has the right to be represented on that committee. International organizations, governmental and

non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the

International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards

adopted by the technical committees are circulated to the member bodies for voting. Publication as an

International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 15878 was prepared by Technical Committee ISO/TC 195, Building construction machinery and

equipment.

4 Operating principle

Asphalt pavers place and pre-compact concrete asphalt mixes using the floating/self-levelling screed method.

The weight of the screed and its forward motion combined with additional vibrating and tamping elements are

used to pre-compact the mixes.
5 Description of an asphalt paver
5.1 General

The design type of an asphalt paver is determined according to the following criteria: undercarriage type,

method of mix transfer from hopper to screed and screed type.
5.2 Undercarriage type
The following types of undercarriage are identified:
⎯ wheeled (see Figure A.1);
⎯ steel tracked with replaceable track plates (see Figure A.2);
⎯ rubber tracked (see Figure A.3).
5.3 Method of mix transfer from hopper to the screed
The following methods are typically used:
