. ", . CITY OF ARDEN HILIB MIH:RANOOM TO: Dorothy A. Person, City 1\dministrator FRCK: Dan Winkel, PUblic works SUperint.......ent}VV DATE: February 3, 1993 SUBJECT: OIIerView of 1993 Pawment Manaqement Rating At'o.hAm.1le It appears that by reviewing the 1993 Pavement Management Report compared to the 1990 supplemental report, the City is realizing a more rapid deterioration of its streets than what was thought as recently as two years ago. It is also obvious to me that streets milt within the last 5 to 12 years are not going to realize their projected life span without at least an overlay, recycling, or reconstruction project. All three of these options are much more costly than the routine sealcoat that is generally used to exterxl. a street's life span. I believe that the city will have to monitor street construction and reconstruction IlIUch more closely to ensure proper construction practices. It was reported over and over again during the 1993 survey that a possible lack of = inadequate canparison may have contrib..1ted to the decline of the streets' surfaces. . A small sanple of canparisons between the 1993 and 1990 supplemental study will help to show how quickly same of these streets have deteriorated. '!he following list is based on a point system that used the same criteria for evaluating streets on both occasions. streets with a rating of 0 to 69 are in need of reconstruction. streets rated from 69 to 89 generally will require an overlay, whereas, streets rated from 89 to 94 usually require only a sealcoat. 'Ihe roadways with ratings of 95 to 100 require routine maintenance, such as crack filling and pothole repairs. Another option that is available, and costs between an overlay and a reconstruction project, is recycling. Recycling was done on Dunlap street and West Round Lake Road last year with goo::l.
