Unbound and Hydraulically Bound Mixtures - Test Method for the Determination of California Bearing Ratio, Immediate Bearing Index and Linear Swelling
Also Known As:
BS EN 13286-47:2012 is a standard that provides test methods for determining the California Bearing Ratio (CBR), Immediate Bearing Index (IBI), and Linear Swelling of unbound and hydraulically bound mixtures. The standard is applicable to mixtures with a maximum particle size of 22.4 mm and includes the determination of vertical swelling when specimens are immersed in water during curing.
The California Bearing Ratio is a measure of the load-bearing capacity of the mixture, while the Immediate Bearing Index is a measure of the material's bearing capacity immediately after construction. These tests are important for assessing the suitability of the mixture for construction applications.
Additionally, this standard includes the determination of linear swelling, which is the change in volume of the specimen when immersed in water. This allows the evaluation of the potential for swelling or shrinkage of the material when exposed to moisture.
