BS EN 13043-2002 is a technical standard that specifies the requirements for aggregates used in road construction. It provides guidelines for the physical and mechanical properties of different types of aggregates used as fillers, base courses, and surface courses in road construction projects. This standard was published by the British Standards Institution (BSI) and it applies to natural aggregates as well as recycled aggregates.
Properties of Aggregates
The physical and mechanical properties of aggregates play a crucial role in determining the performance and durability of road surfaces. This standard defines various parameters that need to be tested and comply with specific requirements. These include particle size distribution, shape, strength, abrasion resistance, fines content, water absorption, and density. Each type of aggregate has different specifications based on their intended use within the road construction project.
Testing Procedures
BS EN 13043-2002 outlines the testing procedures to be followed in order to determine whether an aggregate meets the specified requirements. The tests include sieve analysis, clay and organic impurity content, flakiness index, water absorption test, particle shape index, polished stone value, and aggregate impact value. These tests ensure that the aggregates are suitable for their intended purpose and they can withstand the various loads and conditions experienced by road surfaces.
Benefits of Compliance
Complying with the specifications outlined in BS EN 13043-2002 ensures that the aggregates used in road construction meet quality standards. Using high-quality aggregates in road projects improves the performance and longevity of the road surface. It enhances stability, reduces deformation under traffic loads, minimizes rutting, and increases resistance to abrasion. Additionally, using recycled aggregates that comply with this standard promotes sustainable construction practices by reducing the demand for natural resources.
