Abstract:

Oregon Senate Bill 66 directed the Oregon Department of Transportation to conduct a research project to evaluate the use of recycled plastic products and composite materials containing recycled plastic in construction maintenance. This report documents the installation throughout the state of snow poles, sign supports, fence posts, and a sound wall.

Recycled plastic materials may be more difficult to obtain than standard wood products. Upfront material and shipping costs are more expensive than comparable wood products. Handling of recycled plastic materials is similar to handling treated wood products except recycled plastic materials are heavier. Recycled materials may be more readily recyclable than treated wood products.

Recycled snow poles were easier to install than standard snow poles. Recycled plastic sign supports, fence posts, and sound wall materials, in general, were more difficult to install.

Recommendations from this study include the following:

1) Additional recycled plastic material installations should be encouraged to obtain more information regarding the constructability of recycled plastic materials;

2) Recycled plastic fence posts for installations in areas with dense soils should be ordered wit ha point at one end;

3) Recycled fence posts should be installed by pushing with steady pressure rather than driven with repeated blows; and

4) Recycled plastic boards for sound wall facing should have tongue and groove joints to insure proper interlocking and to reduce the amount of bowing.
