Soil compaction, with leaf abrasion of secondary importance, was concluded to be primarily responsible for the inability of grass to survive in heavily travelled footpaths. Several materials were used in the construction of a grassed walk designed to absorb traffic energy, eliminate compaction and afford wear protection to intermingled grasses. Inverted Coke bottles, bricks, and crushed stone were the experimental materials. The growth of the p i s s was best in the bottle area. However, the bottles were slippery when wet and presented some hazard. Orientation of the bricks to direction of traffic was found to be important. Bricks perpendicular to direction of travel were much more satisfactory than those placed parallel. ‘Manhattan’ perennial ryegrass (Lolium perenne L.) and ‘Merion,’ ‘Pennstar,’ ‘Nugget,’ and Fylking' bluegrasses (Poa pratensis L.) were evaluated as a mixture in these trials. An excellent sod was maintained with the bricks and bottles but not with the crushed stone.
