We've been stuck in a bit of a cold snap here in Wisconsin -- a nice time to kick back on the couch under a blanket with a warm cup of tea for some easy reading. "Easy reading" for me no longer means a steady diet ofÂ knitting magazines and Tony Hillerman novels,Â butÂ instead topics like pervious concrete and sustainable construction. A few great reads I've recently taken in include two white papers from L.M. Scofield -- "How Concrete Contributes to Today's Green Designs" and "Design and Construction of Pervious Concrete Pavements."Â If you've got a little time and want to increase your knowledge base on either of these topics, I encourage you to take a look at these publications.
