Discuss Bituminous Pavement Saw and Seal <br />By: Brian E. Olson, Principal City Engineer <br /> <br />P.W CASE <br /> <br />Background: <br /> <br />The term "Saw and seal" refers to the practice of sawing and sealing joints in pavement <br />to control transverse cracking. In 1996, the State of Minnesota issued a report on the use <br />of the "saw and seal" procedure to accomplish this task. <br /> <br />The purpose of this case is to discuss the possibility of taking a proactive approach to the <br />transverse cracking that occurs on our City Streets and discuss the options to see if this <br />practice should be considered for future projects. <br /> <br />The cost to saw and seal according to the recommendation on the attached guidelines <br />from MnDOT amounts to about $10,000 per mile and $500 per intersection. This is based <br />on a 30 foot separation between joints. <br /> <br />Two candidate projects (see attached) that provide some time to discuss this activity are <br />the new section of Sunwood Drive between County Road 116 and Sunfish Lake <br />Boulevard as well as the new section of Yakima Street that was installed in the Highlands <br />at River Park subdivision. Sunwood Drive NW is a Municipal State Aid route with heavy <br />traffic expected. Yakima Street between Alpine Drive and 155th Lane NW is a local <br />residential road with moderate traffic and 155th Lane NW between Yakima Street NW <br />and the culdesac is a low volume local residential road. <br /> <br />The "saw and seal" of the bituminous on Sunwood Drive NW could be done after the <br />final layer of bituminous is installed and could be done at a cost of ~$5,500. The "saw <br />and seal" of the bituminous for Yakima Street and 155th Lane NW at a cost of -$9,500. <br /> <br />Committee Action: <br /> <br />Based upon discussion <br /> <br />Reviewed by: <br /> <br />City Administrator <br />Public Works Director <br /> <br />PW: 08/19/02 <br /> <br /> <br />
