Method for Quality Testing of Material of Coarse-Grained Soils, in Particular of Sports Surfaces

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention provides a method for quality testing materials of coarse-grained soils, especially for sports surfaces. The process involves preparing a smooth, horizontal section of the soil, positioning a special testing cone above it, allowing the cone to drop into the soil, and then measuring how far the cone penetrates using a distance sensor.

Use CasesContent extracted from patent full text and abstract with AI.

• Quality control of sports field surfaces (such as running tracks, football fields, and playgrounds)
• Assessment of soil compaction and consistency in civil engineering and construction projects
• Routine inspection and maintenance of artificial turf or granular sports grounds
• Research and development in soil mechanics and material testing laboratories

BenefitsContent extracted from patent full text and abstract with AI.

• Enables objective, repeatable assessment of soil or sports surface quality
• Supports maintenance and durability of sports surfaces by detecting improper compaction or material degradation
• Simple and efficient testing method, potentially saving time and resources compared to traditional sampling and lab analysis
• Can help optimize ground preparation for enhanced athlete safety and performance
