The overarching goal of the Road Construction Machinery cluster is to create a uniform understanding/standard for the definitions in ISO 15143. Within the ISO standard, some parameters are not regulated concretely enough. Furthermore, parts of the parameters listed there are not relevant for practical application.

Due to the lack of standardization, room for interpretation arises, which allows for different definitions on the OEM side and thus causes corresponding isolated solutions (data silos) on the user side.

This makes meaningful use, a manufacturer-independent comparison, and the integration of machine status data into internal systems and processes very difficult or impossible for machine users.

To increase the usability and deployment possibilities of the data, the parameters and their meanings must be defined in detail and clearly, in collaboration with all stakeholders, from the manufacturer and service providers to the end user.

This unification aims to create clear added value for the user regarding the machine status data defined in ISO 15143-3. Manufacturers benefit from a targeted, cross-manufacturer definition while simultaneously avoiding isolated solutions and proprietary interpretations.

The elaboration was carried out taking into account the following two requirements:

• The ISO standard is the guideline, and there must be no alteration of existing fixed definitions.
• The definitions refer to the OEM server's data interface. Data acquisition and data transmission to and from the machine are not part of this cluster.

Since ISO 15142-3 currently only includes machine status data, in the next step, required quality and process data for road construction machines will be developed. When defining this data, existing interim results, e.g., from the CECE initiative, will be reviewed and aligned with the requirements of OEMs and users. The goal is to define the required metrics clearly and unambiguously. This information is of great importance for users in order to further optimize construction site processes. For this purpose, it is necessary to define and consider machine types such as pavers, feeders, or asphalt rollers separately. For each machine type, main activities will be determined, and along with them, required data fields including descriptions and measurement accuracies (query frequency, unit) will be defined.
