D338518 Pdf [hot]: Astm

is the definitive international standard for field-measuring the infiltration rate of liquids into soils using a double-ring infiltrometer . Managed under the jurisdiction of ASTM Committee D18 on Soil and Rock , this active standard spans 8 pages and details the required engineering equipment, test setups, and formulaic calculations necessary to evaluate site drainage capacity. Civil engineers, hydrogeologists, and environmental scientists use the official ASTM D3385-18 Document to inform storm-water management design, agricultural irrigation layouts, and landfill liner efficiency. 1. What is the Core Purpose of ASTM D3385-18?

Planning irrigation schedules and designing drainage systems to prevent waterlogging. astm d338518 pdf

Heavy clay soils that exhibit macro-cracking or desiccation cracks allow water to bypass the soil matrix entirely via preferential flow paths, skewing the structural data. Heavy clay soils that exhibit macro-cracking or desiccation

The ASTM D3385-18 test method involves a simple and straightforward procedure to measure the permeability of porous concrete. The test apparatus consists of:

Once you have your licensed PDF, combine it with proper field training and quality control (per ASTM D3740) to produce reliable infiltration data that will stand up to peer review and regulatory scrutiny.
