BS EN 13179-1:2013

What is BS EN 13179-1 - Delta ring and ball test for filler aggregate about?  

BS EN 13179 is a European standard on tests for filler aggregate used in bituminous mixtures. The main aim of the BS EN 13179 series is to provide best industry practices to determine the quality and performance of construction materials to meet your specific engineering needs. 

BS EN 13179-1 is the first part of the BS EN 13179 series that specifies the procedure used to determine the stiffening effect of filler aggregate when mixed with bitumen. 

Who is BS EN 13179-1 - Delta ring and ball test for filler aggregate for? 

BS EN 13179-1 on tests for filler aggregate is useful for: 

• Manufacturers of waxes, bituminous materials and other petroleum products 
• Civil engineers 
• Contractors 
• Manufacturers of mineral aggregates 
• Manufacturers and suppliers of construction materials 

Why should you use BS EN 13179-1 - Delta ring and ball test for filler aggregate?  

Mineral filler aggregates play an important role in asphalt mixtures because they fill voids in the paving mix and improve the cohesion of the asphalt binder. The bituminous mixes are to be properly designed to satisfy the design requirements of stability and durability. 

In this regard, BS EN 13179-1 navigates you through the test procedure to determine the stiffening effect of filler aggregate when mixed with bitumen. 

BS EN 13179-1 covers guidance on the delta ring and ball test and walks you through the test procedure. 

Compliance with the tests can help evaluate aggregates that are fully coated with bitumen and ensure the voids within the bituminous material are sealed up. As such, the durability of the pavement/road can be enhanced by the impermeability achieved. Thus, demonstrating the presence of stiffening effect can ultimately determine the mixture performance that plays a crucial role in enhancing the service-life of your construction works. 

What’s changed since the last update?  

BS EN 13179-1:2013 supersedes EN 13179-1:2000. BS EN 13179-1:2013 includes some technical changes with respect to EN 13179-1:2000. These include: 

• Clause 7 has been completed by the following sentence: "For some types of filler, the stiffening effect may make the mixture of filler and bitumen so stiff that a homogeneous mixture cannot be obtained by stirring for the specified time. If a homogenous mixture cannot be obtained, the test shall be stopped. The result shall be recorded (9.1 (b)) as “greater than 25 °C”
