En~neer Background: The term "Saw and seal" refers to the practice of sawing and sealing joints in pavement to control transverse cracking. In 1996; the State of Minnesota issued a report on the use of the "saw and seal" procedure to accomplish this task. The purpose of this case is to discuss the possibility of taking a proactive approach to the transverse cracking that occurs on our City Streets and discuss the options to see if this practice should be considered for future projects. The cost to saw and seal according to the recommendation on the attached guidelines from MnDOT amounts to about $10,000 per mile and $500 per intersection. This is based on a 30 foot separation between joints. Two candidate projects (see attached) that provide some time to discuss this activity are the new section of Sunwood Drive between County Road 116 and Sunfish Lake Boulevard as well as the new section of Yak/ma Street that was installed in the tJ_ighlands at River Park subdivision. Sunwood Drive NW is a Municipal State Aid route with heavy traffic expected. Yakima Street between Alpine Drive and 155th Lane NW is a local residential road with moderate traffic and 155th Lane NW between Yakima Street NW and the culdesac is a Iow volume local residential road. The "saw and seal" of the bituminous on Sunwood Drive NW. could be done after the final layer of bituminous is installed and could be done at a cost of -$5,500. The "saw and seal" of the bituminous for Yakima Street and 155th Lane NW at a cost of -$9,500.
