Abrasion

Abrasiveness was measured using ASTM F1015 method (ASTM 2000e). Friable foam blocks were attached to a weighted platform that was pulled over the playing surface in four directions (Fig 25 and 26). The weight of foam abraded away determines the relative abrasiveness of the surface. The friable foam blocks used as the test material were rigid closed-cell isocyanurate. An abrasiveness index is calculated by taking the weight loss for each set of four blocks in grams and dividing by 0.0606 as per ASTM F1015.

abrasion testing

Abrasion data is shown in Table 17. All infilled treatments were less abrasive than Astroturf. For treatments receiving wear, the abrasion index was lower in 2004 (Table 18) compared to 2003. This trend was not evident in the no-wear treatments. Grooming tended to lower the abrasiveness of the treatments. We continue to try to modify the abrasion testing method so we can produce data on natural turf.

Treatment 7-Aug 30-Sep 31-Oct

¹Grooming of wear and no wear plots occurred on 9-10 Oct 2003.

²Abrasion index is determined by pulling foam blocks in a weighted sled across the plots in 4 directions and determining the loss (by weight) of the blocks. Abrasiveness index = [(starting block weight - final block weight)/6] *100.

³ 7 Aug testing performed after wear simulating 44 games. 30 Sep testing performed after wear simulating 88 games. 31 Oct testing performed after wear simulating 92 games.
