ISO 15878:2021 - Overview
ISO 15878:2021 specifies the content of commercial specifications for paver‑finishers used in road construction and maintenance for the placement and pre‑compaction of paving materials. It defines the machine (tractor and free‑floating screed), components, terminology and parameters for technical characteristics, measurements and configurations. The standard clarifies scope and terminology, introduces defined compaction types and consolidates machine description and operating principles into commercial specification requirements. Note: it does not cover commercial specifications for road wideners.
Key topics and technical requirements
- Definitions and terminology for paver types (pre‑compaction, compaction, high‑compaction), screeds, hopper, conveyor, mat, GRP (ground reference plane) and more - enabling consistent specifications and communication.
- Commercial specification structure including type of paver‑finisher, basic and additional characteristics, and optional equipment.
- Material feed and transfer: conveyor and auger options (slat, screw, gravity), conveyor flow controls and conveyor capacity calculation based on bulk density, tunnel area, speed and efficiency.
- Screed features: fixed vs extendable screeds, crown and crown control, extension slope, bracing and attachments (cut‑off plates, bevel edgers).
- Control systems: automatic grade control, 3D grade/paver control and automatic screed/feeder systems for profile and material flow accuracy.
- Operator and machine measurements: operating vs shipping configurations, operating mass, shipping mass, overall dimensions (height/width/length), clearance circle, paving speed and material bulk density measurement procedures.
- Health/environment features: emission reducing devices (ERD) for screed/operator station areas.
- Annex A: informative examples of structure and dimension characteristics for asphalt pavers.
Practical applications
- Preparing consistent tender documents and procurement specifications for municipal authorities and contractors.
- Guiding OEM product data sheets and comparison charts to match buyers’ requirements.
- Assisting site engineers and fleet managers in selecting paver models that meet dimensional, control and material‑handling needs.
- Supporting equipment integration (3D control systems, feeders) and ensuring interoperability.
- Informing testing laboratories and conformity assessment on measurement conditions and definitions.
Who uses this standard
- Equipment manufacturers and designers
- Procurement/specification writers for public works and contractors
- Road construction engineers and fleet managers
- Testing labs, certification bodies and standards committees
