Earthworks - Part 4: Soil Treatment with Lime and/or Hydraulic Binders
Also Known As:
The DIN EN 16907-4 standard provides guidelines and requirements for the treatment of various materials during the construction and maintenance of earth structures. This standard specifically focuses on the treatment in layers rather than by columns and applies to natural soils, weak rocks, intermediate rocks, chalk, recycled materials, and artificial materials.
The standard covers the constituents of the mixtures used, the methodology for preliminary laboratory testing, performance classification in the laboratory, execution, and control. It distinguishes between two types of treatments: improvement and stabilization. The laboratory performance classification for improvement is based on short-term performance, while stabilization considers medium to long-term performance.
The standard includes informative annexes that provide examples of good practices for execution and control. It is worth noting that this standard differs from EN 14227-15, which focuses solely on stabilization in pavement applications. The performance classification for stabilization in EN 16907-4 generally aligns with the classification in EN 14227-15, with the exception of the performance classification diagram according to "Rt and E" specific to pavements in EN 14227-15. In EN 16907-4, this diagram is replaced by a performance classification diagram specific to earthworks.
