ASTM WK36211

    Work Item: ASTM WK36211 - New Test Method for MEASUREMENT OF SYNTHETIC TURF SYSTEM INFILL MATERIAL DEPTHS IN THE LABORATORY AND FIELD USING A CONSTANT GROUND PRESSURE 3-PRONG GAUGE

    Developed by Subcommittee: F08.65 | Committee F08 | Contact Staff Manager



    1. Scope

    THIS TEST METHOD PROVIDES A CONSISTENT AND REPEATABLE METHOD FOR MEASURING THE DEPTH OF INFILL MATERIAL ABOVE THE CARPET BACKING IN INFILL SYNTHETIC TURF SYSTEM. THE METHOD MINIMIZES DEPTH GAUGE ERRORS ASSOICATED WITH NON-UNIFORM INFILL MATERIAL COMPACTION, AND NON-UNIFORM DEVICE GROUND PRESSURE BY AN INDIVIDUAL OR BY DIFFERENT INDIVIDUALS.

    THE RELATIONSHIP BETWEEN INFILL DEPTH AND G-MAX, ALTHOUGH NOT PRECISELY DEFINABLE AT THIS TIME, IS SIGNIFICANT WITHIN THE FRAMEWORK OF ANY GIVEN SYSTEM OF INFILL SYNTHETIC TURF. THE MEASUREMENT OF INFILL DEPTH HOWEVER HAS BEEN ACCOMPLISHED BY MANY USING A WIDE VARIETY OF DEVICES AND APPROACHES. VARIATION IN DEVICE SIZE AND BEARING SURFACE AREA, GROUND PRESSURE OF THE DEVICE, NUMBER AND SIZE OF PROBES, MEASUREMENT SCALE, READING ACCURACY MEASUREMENTS, VARIATION IN THE DENSITY OF IN PLACE INFILL, VARIATION IN THE DEPTH OF INFILL WITHIN SMALL AREAS, AND OTHER CONDITIONS SUCH AS BURIED FIBERS AND THIN BACKING SYSTEMS, MAKES CONSISTENCY NOT POSSIBLE. THIS METHOD IS INTENDED TO PROVIDE A CONSISTENT METHOD WITH STANDARDIZED DEVICES FOR MEASUREMENT OF INFILL DEPTH.
