EUGENE <br />VOLUNTEERS FROM OPPORTUNITY VILLAGE SIGN UP TO HELP MAINTAIN LOCAL PARK <br /> <br />AROUND THE CITY <br /> <br />New Sustainable Street Repair Process Eliminates Cement Dust <br />Eugene’s award-winning, sustainable road-repair practices have become even more healthful, thanks to a new technique <br />for constructing cement-treated road bases. <br /> <br />Eugene Public Works helped pioneer a process for recycling <br />streets in place. In this process, the asphalt pavement is mixed <br />with the road-base gravel and a few inches of soil using a 70,000- <br />pound rototiller. A cement slurry is then applied over the blended <br />material, rototilled a second time and compacted, creating a <br />cement-treated base. In the past, the cement was added in a <br />powder form, which was then watered, tilled and compacted to <br />form the reinforced base. However, the use of cement powder <br />often created “fugitive dust” that got on construction workers, <br />equipment, and even on residents and their vehicles if they drove <br />through the work zone before the cement was thoroughly worked <br />into the base. <br /> <br />The new process, which is being used on repairs to Shasta Loop, <br />Firland Boulevard and 43 Avenue, eliminates the cement dust <br />rd <br />factor. The contractor, Knife River, mixes cement powder, sand <br />Contractor’s crew applies thick slurry of cement and sand to <br />form road base on Firland Boulevard <br />and water, offsite, to create a thick cement slurry, which is <br />transported in a cement-mixer truck and spread over the prepared subgrade. The slurry is then tilled in and compacted to <br />form a cement-treated base as strong, or stronger, than the base formed using powdered mix. <br /> <br />City Public Works Engineering staff required the cement slurry process after researching road-building advancements in <br />other states. Other sustainable road-repair practices in Eugene include the use of reclaimed asphalt paving and reclaimed <br />asphalt shingles in asphalt mixes and the use of warm-mix asphalt, which saves on the energy needed to heat the asphalt <br />and also reduces off-gassing of volatile organic compounds. <br /> <br />For more on this year’s in-place road recycling projects, contact project manager Kerry Werner at 541-682-5477. <br /> <br />Writing Workshops at Library <br />In connection with Create! Eugene, the Downtown Eugene Public Library will host three, free writing workshops in August. <br /> <br />At the first workshop, on Thursday, Aug. 7, at 6 p.m., Melissa Hart will lead a fun, lively discussion, entitled “Writing About <br />Animals.” Hart’s work has been widely published, including her latest book "Wild Within: How Rescuing Owls Brought One <br />Family Together." Monday, Aug. 18, at 6 p.m., Oregon Book Award finalist Toni Hanner will teach “Jump-Start! A Poetry <br />Writing Workshop.” Finally, on Saturday, Aug. 30, at 1 p.m., learn how to “Write the Perfect 10-Minute Play” at a three-hour <br /> <br />EUGENE CITY COUNCIL NEWSLETTER PAGE 1 <br />August 7, 2014 <br />
