(BASS), of North Little Rock, Arlu\I\Sas, for Englewood 's 1993 Micro-surfacing Program. PREVIOUS COUNCIL ACTION Resolution No. 52 , Series of 1992, and Resolution No. 38, Series of 1991, approving n~otiating contracts and awarding negotiated contracts for the 1992 and 1991 Micro-surfacing Programs respectively . BAC~GROUND Since 1987, an average of $260,000 h as been all oc.1ted :\I\I\ually in the Public Improvement Fund for contract street maintenance, primarily sll'1rry s~al and micro-surfacing . For the past six years, the City has negotiatro with BASS, Inc ., o r Nort.1-i Little Rock, Arkansas, to come to Englewood and construct our slurry and ·micro-suri~-ing ?rograms. BASS ha s now placed a total of 890,000 square yards of our design products (approximately 360 blocks or 45 miles of roadway). Bids for standard • . ...rry in the m£tro area for 1993, with local contractors and lower quality components arc expected to be in the $0.85 to $0 .95 per square yard range . Fall 199'.t. !:.;de for micro-surfacing by the Colorado Department of Transportation (COOT) yielded bids for a product that we believe to be far inferior to our own in the $130 .00 to $140 .00 per ton range . Typically our specified quality emulsion, aggregate, and application equipment tend to push those costs upward $20 .00 to $30 .00 per ton . Printed on Re cvcleo Piper - !>TAFF ANALYSIS Staff continues to monitor slurry seals and mic.ro-su•facing constructed in the metro area during th.e previous si x construdion seasons. The workmanship of others, particularly with micro-surfacing, appears to be of significantly lower quality than that continually pro\'ided by BASS, Inc ., and far below a performance level ;•cceptable to the City of Englewood . For \!!.\explained reasons, there remains much u,,::onsistenc.y in the typical mix designs utilized wit h in the metro area . The 1992 p roducts of ;:,tl-ier user agencies appear again significantly .iiffertnt than those specified in previous seasons. This leads us to continue to believe that co1,tractors and /or user a gencies are still experimenting and are not totally satisfied with earlier products . Most micro surfacing products placed by others during the 1992 season generall y appear at thi s time to be achieving only marginally satisfactory results; many areas of localized failure have been noted . Repxts by user agencies still suggest that 1992 _ lurries continu to have slow traffic ready times, ii' the 4 to 5 hour range . It is too early to fairl y evaluate the 1992 micro-surfacing \.est sections by others . Throughout o u r six yu r ex perience with "Englewood" slurry, micro-surfacing, and BASS , Inc .. ci tizen feedb a ck conti nues to q uestion our not including more streets in our annual micro-s urfaci ng programs . Minimal inconvenience during construction (our I ,affi c ready ti.:nes have remained under 2 hours1 and product quality appear to meet the expectations of our ci ti zenry . Sta ff continues to be pleased with our product's performance. The extended p aver,,ent longe vity from sl u rry and rni a ·o-surfacmg applications continues to look promising . •• As you will recall , in 1991 Englewood took the product development initiative to move • forward and address the mai ntenance needs of many of our more heavily utilized arterial, ,;ollector, and industrial streets . "Englewood '' :nicro-surfacing was introduced, a product d r_-s igned lo address the maintenance needs of roadways subjected to excessive traffic volumes resU! ti ng in pavement rutting and lanes requiring leveling treatment'.-1 addition lo wearing CO\:rses and surface seal s . "Engl ewood" micro-surfacing was designed , and has been constructed on selected arterials, collectors, industrial and local serv ice streets by Bituminous Asphalt Sealing Speciali sts (BASS ), Inc, in both our 1991 and 1992 micro-surfacing programs . As you will recall . micro-s urfac ing requires highly s pecial ized cons truction equipment. From our last two years experie1,ce, we know that continuous use of micro-surfacing eq uipment produces a s uperior product compared to that applied with truck mounted type machines, similar to those c.tilized in our earlier years slurry applications. Standard s!urry machines are not capable of co nstructil"'3 micro-surfacing. However, continuous micro-surfacing equipment can apply sta ndard ~.u-ry products. Although the number of continuous micro-surfacing m achines contin ues to grow 11-irou ghout the country, none are owned or operated by Colorado contract ors . BAf', Inc . owns a nd operates 2 of these machines . They continue to be the onl y contractor availa ble in our area with d01lonstrated r.ucoessful ~pplications utilizing the Ergon products and mix desi3ns that we have develoi:-ed , and that achieve our desired res ults. We ha,·e confidence that this specialized contrac'tcr, with whom we h ave 6 years o f progressive successful experience , can accomplish our 1993 project to our sa tis fa ct; ')n in a ti mely and cost effecti ve manner. BASS, Inc. is currently committed to • ,nulti -y ear contracts in Honduras , San Sal vador, and Nicaraguz However, the equipment necessary to a cc omplish our 1993 project can be made available in t!:i e latter part of June. •• Although our efforts in 1993 will be concentrating on local service and minor collector streets, we believe that our micm-surfacing product is superior to previous years standard slurry seal applications, allowing much more flexibility in use . The individual components of our "Engl ewood " micro-surfaci:,g design are very similar to those in our earlier slurry seal products. However, micro-su,-facing utilizes a polymer modified Ergon emulsion, more chemically complex than our earlier siurry applications . Slurry seal is a single thickness application product. Micro-surfacing has the capability of being applied in whatever thickness is necessary to address our maintenance requirements. It can be utilized for rut filling and leveling as well as for overall roadway sealing . In past years, chemical makeup allowed for 17 second break times . Applications on collector an d arterial streets could be opened to through traffic in 20 to 30 minutes, if necessary . Our design will con ti nue to specify the quality gray granite aggrrgate from Asphalt Paving Company, Golden , C olorado. However, staff has recently worked w ith the ERGON materials laboratory in Jackson , Mississippi , to "fine tune" our micro-s urfa cing emulsion formula . Hopefully, we will be able to slightly retard the products breaktime and provide extra seconds for "'hand work" arounr ·eet intersections . FINANC ,L i.MPACT S-l06 ,000 is a,·a il able in the Public Improvement Fund , Road and Bridge account for 1993 . Preliminary com·ersations with BASS , In c. suggest a willingness to return to Engle\\'ood in 1993 and construct micro-surfa cing at a unit p:ice similar to that in our 1991 and 1992 contracts ($152 .18 per ton). The 1991 cortract ·.vas for $280,000 (approximately 160,000 square yards or 60 blocks). Funding for 1992 was limited to $260,000 for micro-s urfacing • (approximately 185 ,000 squ,,re yards or 70 blocks). In 1992, with minor rut filling , surfacing le\'eling and normal residential application rates, we had a prod uct yield that generated per square ya rd costs of approximately $1.37. This cost remains in th e magnitude of -10"1, of the cost of asph altic concrete overlay w hile still allowing us to co rrect many of the irregularities within a structurally sound roadway surface. • For 1993, we are recommending a contract with BASS , Inc . for approximately 20-1 ,000 s.:iuare yard s of micro-s urfacing (80 blocks -approximately 10 mil es of Englewood streets). At a unit price similar to that negotiated in both 1991 and 1992, thi s would result in a co ntract in the $310,000 to S315 ,000 range . The balance of funding in the 1993 Road and Bridge PTF acco unt will be utilized for asphaltic concrete overlays and associated maintenance program administration, testing, and inspection . Note : D ue to the varying application rates of micro-surfacin~, , .. ;th ever changing roadway conditions, micro-surfacing 1s contracted by unit weight apphtc.i (tons). OTHER The attached li sts of streets and avenues proposed for inch.:sion in our 1993 overlay and micro-surfacing programs are for your information . It is intenJeJ to be representative of the proposed programs and is , of course, subject to your re view and comment. Since 1987, we have addressed the maintenance needs of only 45 miles of our approximately 120 mil e roadway system . The 1993 program will add only about 10 miles to that total. Consequently, many deserving maintenance candidate--•is t within our street system. A progressive slurry seal /micro-surfacing prog ram woul. address all of the streets within the system over a se,·en year period, suggesting that the annual budget for this activity rem i\ins at 45 % of id ea l funding level s.
