Statistical monitoring for continual quality control of railway ballast

作者：

Highlights：

• An innovative statistical monitoring system for railway ballast is introduced.

• It bridges the gap between the traditional biannual material inspections.

• It allows for closer test intervals ensuring better detection of fluctuations in ballast quality.

• It thus can help to reduce maintenance costs.
