PD CEN/TS 13286-54:2014

What is PD CEN/TS 13286-54 - HBM freeze-thaw resistance about?  

If unbound and hydraulically bound mixtures are susceptible to constant freezing and thawing, then they create dangerous conditions for motorists and commuters.

PD CEN/TS 13286-54 serves specifications for unbound and hydraulically stabilized soils, enhancing the usability, application, and performance in road construction applications.

PD CEN/TS 13286-54 is the 54^th part of the ‘Unbound and hydraulically bound mixtures’ multi-series, specifies a test method for the determination of the resistance of a hydraulically bound mixture to the cyclic action of freezing and thawing.

The method described is suitable for hydraulically bound mixtures, including hydraulically stabilized soils, in accordance with BS EN 14227-1 to BS EN 14227-5 and the range of strengths covered by that standard.

When required, a method for determining the change in height of a hydraulically bound subject to freeze-thaw is also specified in PD CEN/TS 13286-54. When required, a method for determining the freeze-thaw resistance of a hydraulically bound mixture in the presence of salt also is specified in PD CEN/TS 13286-54.

Who is PD CEN/TS 13286-54 - HBM freeze-thaw resistance for? 

PD CEN/TS 13286-54 on unbound and HBM freeze-thaw resistance is useful for: 

• Relevant government / municipal authorities
• Highway and road transport authorities
• Manufacturers and suppliers of unbound and hydraulically bound mixtures
• Suppliers of binders such as cement, fly-ash needed to make hydraulically bound mixtures
• Civil engineers / contractors
• Product design engineers / innovation teams
• Inspection and quality assurance personnel

Why should you use PD CEN/TS 13286-54 - HBM freeze-thaw resistance?  

A hydraulically bound mixture is a mixture of aggregate, water, and hydraulic binder and is one of the most commonly used materials in pavement sub-base layers. For the optimum functioning of hydraulically bound mixtures and unbound mixtures, they need to be resistant to freezing and thawing.

PD CEN/TS 13286-54 provides you with guidance to conduct the freeze-thaw resistance test in terms of details on the apparatus, test specimens, and initial (first stage) curing of test specimen requirements for the fresh mixture.

PD CEN/TS 13286-54 guidelines enable you to standardize the requirements for hydraulically stabilized files, ensuring cost-effectiveness and limiting the environmental impact on roads, airfields, and other trafficked areas. Using the test methods described in PD CEN/TS 13286-54 help you to improve the service life of your construction, minimize costs, and prevent accidents.
