Slaff introduced 'Enelewood" micro-surfacing in 1991 . Our objective was to develop a maintenance altematlve to address the maintenance needs of roadways subjaclad to exceulYe traffic volume,, resulting In pavement rulling and lanes requiring leveling trealmt!nts along with new wearing COUIHS and surface seals. BASS, Inc. has satisfactorily participated in a partnership arrangement with the City for the last nine years to construct our sluny and micro-surfacing programs, having now placed a total of 1,500,000 square yards of our design products (approximately 615 blocks , or n miles of roadway). Micro-surfacing requires highly specialized constr~.:tion eq....-it From our last five years' experience , we ~ that the use of continuous micro-surfacing equipment produces a superior product compared to that applied - truck mounted type machlnet . Continuous equipment provides consistency of application and minimizes HM'II by reducing equipment stops and starts. Truck mo!Jntad equipment was used in the construction of our earlier slurry products . Continuous micro-surfacing equipment can apply standard slurry products while standard slurry machines are not capable of applying micro-surfacing . The number of continuous micro-surfacing mach · es continues to grow throughout the country ; BASS , Inc . owns and operalal 2 of these machinea . BASS, Inc. ha successfully constructed micro-surfacing on selected -.;aJs, cottectors , industrial and local se!Vice streets in our 199 1, 1992, 1993, 1994 and 1995 micro-surfacing programs . Sta ff continues to monitor slurry seal and micro-surfa ci ng activities in the metro area . The workmanship of BASS , Inc .. particu~•rly with micro-surfacing , ap~Ja rs to rema in superior . Milch inconsistency exists In the mix deslgns used by othe r,.· in the metro area, although many jurisdictions are again requiring !!le gray granite aggregate that we have rocom."8nded and specified since 1987. Many Olher user agencies continue to modify their specificati ons , su~g• sting that they are not completely satisfied with earlier products . We have noted areas of localized failure in ,,iicro-surfacing products placed by others during 1992 and 1993, indicating only marginally satisfactory resu lts.

LIST OF ATTACHMENTS For your inlonnalion, the atta ched lists streets and aventMS proposed for indusion In our 1996 CMlflay and micro- surfacing proscams . They are Intended to m, repn,sentative of the proposed programs and are, of course, subject to your review & id comment. Since 1987, we have addressed 1he maintenance needs of some 77 miles of our approximately 120 mile roadway system . The 1998 program will add about another 10 miles to that tolal. Consequently , many deserving mainlenance cand idates exi5t within our street system . A progressive slurry seaVmicro-surfacing program would address all of the streets with the •Y i tam over a seven year period , suggesting that the annual budget for this activity rema ins at appro xi mately 50% of Ideal funding levels .
