GreenStep City Best Practices Environmental Management

Sustainable Purchasing
no. 15

Adopt environmentally preferable purchasing policies and practices to improve health and environmental outcomes.
  Best Practice Action 5      [ 1 2 3 4 5 6 7 8 ]       [all actions]

Set minimum standards for the percentage of recycled-content material in asphalt and roadbed aggregate or other construction materials, and for compost and warm mix asphalt use.

 
Follow latest MnDOT specifications for recycled glass and aggregate in roadbeds.
All paving projects incorporate recycled asphalt (RAP); report use of warm-mix asphalt; use recycled plastic manhole adjusting rings; use MnDOT compost specification 3890 for soil amendments in parks, boulevards, stormwater installations.
Follow MnDOT specs for RAP and shingles (asphalt shingle manufacturing scrap and/or shingle tear-off scrap) in asphalt mixtures.

Hutchinson

Date action report first entered:   03/02/2016
Date of last report update:   03/02/2016

Implementation details:
On all road reconstruction projects, 100% of asphalt is either reused in the project, or recycled. Generally, between 90-95% of asphalt is reused on the project to establish the aggregate roadbed, with the goal being to reuse 100% of reclaim. The remaining asphalt is recycled at the city-owned and operation Creekside facility to be used in other projects. Additionally, 100% of concrete from reconstruction projects is recycled at the Creekside facility, and is used as bitcon and crushed concrete.

Red Wing

Date action report first entered:   01/30/2013

Implementation details:
We currently recycle 100% of asphalt pavement. About 95% goes back into new asphalt and 5% goes into roadway aggregate. We currently recycle approximately 95% of the concrete/blocks/bricks/etc. into roadbed aggregate. The remaining 5% has metal reinforcing bars/mesh that is too hard to put through the crusher. We currently reuse approximately 40% of our roadbed aggregates. It’s hard to increase this amount because of contamination with the sub-grade materials during the reconstruction process. We recycle 100% of our old manhole castings, valve boxes, metal pipes, old signs/posts, etc. The only one of these items we typically purchase as a recycled material is the asphalt, which is allowed to have up to 20% recycled material. The other items, except the metal, we recycle ourselves and use on our own projects, so the costs of salvaging, hauling, crushing, etc. are the cost of the recycled material.
