    New Guide for Assessing Some Characteristics of Turfgrass Surfaces for Thoroughbred Horse Racing

    (What is a Work Item?)

    Developed by Subcommittee: F08.28 | Committee F08 | Contact Staff Manager


    1. Scope

    1.1 This guide covers the assessment of some characteristics of natural turfgrass thoroughbred horse racing surface systems (and other equestrian-turfgrass surfaces) using lightweight portable apparatuses. This practice is applicable for comparing natural surfaces and for assessing the effects of management practices on surface and sub-surface characteristics. This guide is applicable to the use of multiple devices including impact devices, penetrometers, shear vanes, and moisture probes. In the case of impact devices, they may also be used to assess the compactibility of natural surfaces by recording Gmax values, penetration of successive impacts, conversion/computation of CBR values, or any combination or all. 1.2 This guide provides a procedure for assessing characteristics in the field, on actual playing/running surfaces and on research plots using ASTM Test Methods and other methods. For impact testing ASTM F1702; ASTM D6780 for Time Domain Reflectometry (TDR) for soil moisture and density; ASTM D7380 for soil compaction determination using a dynamic cone penetrometer; and ASTM D2573 for Field Vane Shear Test (with modified shear vane for turf application, such as Turf-Tec TSHEAR2-M). This guide may also be applicable for deployment of other apparatus and test methods.

    Horse track surface experts use or desire to use track evaluation and characterization methods to evaluate race track surfaces. However, there is no guidance as to type of equipment which may be utilized and in what manner to employ its use.
