The specifications for geotextiles in railway projects typically include factors such as material type, weight, strength, permeability, and durability. These geotextiles are required to have high tensile strength and puncture resistance to withstand the heavy loads and dynamic forces exerted by train traffic. They should also possess appropriate permeability to allow for effective drainage and prevent water accumulation. Additionally, geotextiles used in railway projects should be chemically stable, resistant to degradation from UV exposure, and capable of withstanding various environmental conditions.
The specifications for geotextiles in railway projects generally include requirements for strength, durability, permeability, and filtration. These geotextiles should have sufficient tensile strength to withstand the dynamic loads imposed by trains and maintain their integrity over time. They should also be resistant to degradation caused by UV exposure, chemical exposure, and biological factors. The permeability of geotextiles is crucial to ensure proper drainage and prevent water accumulation, which can lead to instability. Additionally, the geotextiles should possess excellent filtration properties to prevent the migration of fine particles and maintain the stability of the railway subgrade.
The specifications for geotextiles in railway projects typically include factors such as the tensile strength, puncture resistance, elongation properties, and durability of the material. The geotextile should also have the ability to separate and stabilize the soil layers, provide filtration to prevent soil fines from clogging drainage systems, and possess adequate permeability to allow for efficient water drainage. Additionally, geotextiles used in railway projects must meet certain standards for dimensional stability and resistance to environmental factors such as UV radiation and chemical degradation.
