What is BS EN 13924-1 - hard paving grade bitumen specifications about?  
The dynamic properties of bitumen make it a preferred ingredient in the construction of roads, helipads, highways, runways, asphalt pavements, and roofing.
The BS EN 13924 series discusses bitumen and bituminous binders. BS EN 13924-1 is the first part of the multi-series, and provides a framework for specifying the properties and relevant test methods for hard paving grade bitumens that are suitable for use in the construction and maintenance of roads, airfields, and other paved areas.
Who is BS EN 13924-1 - hard paving grade bitumen specifications for? 
BS EN 13924-1 on hard paving grade bitumen specifications is useful for: 
- Manufacturers of bitumen and bituminous products
- Manufacturers of binders and sealing materials
- Construction and civil engineers
- Product development teams / innovation teams
- Contractors
- Road maintenance authorities
- Quality control / testing personnel
Why should you use BS EN 13924-1 - hard paving grade bitumen specifications?  
The viscosity of bitumen makes it an ideal binder. BS EN 13924-1 provides general requirements and test methods, properties and related test methods, assessment, and verification of constancy of performance – AVCP, informative properties, test samples, testing, and compliance criteria.
The test methods described in BS EN 13924-1 are suitable for quality control purposes during the production of plant mix and for checking compliance with a product specification.
BS EN 13924-1 extends the range of grades specified in EN 12591 [2], following the wider use of materials for road construction and maintenance having very high modulus values.
BS EN 13924-1 can be read in conjunction with National Guidance Documents.
For hard paving grade bitumens, the testing of the five essential characteristics, according to the mandate M/124 also gives an indication that its intrinsic cohesive properties are adequate for its normal use. 
BS EN 13924-1 guidelines enable you to manufacture bituminous binders while evaluating the anti-cracking capabilities of the binder at low temperatures. As a result, you can improve the quality of construction materials for optimum durability and performance. BS EN 13924-1 contributes towards ensuring the longevity of paving solutions so that users have uninterrupted access to them.
