COUNCIL GOAL AND PREVIOUS COUNCIL ACTION
Resolution No. 44 , Series of 1996, Reso lution No. 35 , Series of 1995, ResoMion No . 40 , Series of 1994,
Resolution No . 39, Series of 1993, Resolution No . 52, Series of 1992, and Resolution No . 38, Series of 1991,
app roving negotiating contracts and award ing negotiated contracts far Ile 1996, 1995, 1994, 1993, 1992, and
1991 Micro-surfacing Programs respectively .
RECOMMENDED ACTION
We are seeking Council approval of a Resol ution allow ing a negotut,ed contract 1"ith Bituminous Asphalt Seal ing
Specialists , Inc ., a.k.a., BASS , Inc .. in an amount not to exceed $380.000 for our 1997 Micro-surfacing Program .
BACKGROUND , ANALYSIS AND AL TERNA Tl\lES IDENTIFIED
Micro-surfacing is a cost effec.'i,e maintenance alternative that provides rut filling , leveling of existing pavements .
a surface seal and a new wealing surrace . The finished product is jet black, aesthetically pleasing, and exh ibits
more traction than the uriginal asphaltic concrete (improved safety ).
St~ff introduced "Englewood" micro-surfacing in 1991 . Our objective was to develop a maintenance alternativ e to
address tt.e maintenance needs of roadways subjected to excessive traffic volumes resulti ng in pavement rutting
and lan es requ irin g leveling treatments along with new weanng COIJ1Sl!!S and surface seals . BASS has
satisfactorily participated in a partnership arrangement with th e City fclr the last ten years to construct our slurry
and micro-s urfacing programs . having now placed a tota l of 1,750,000 square yards of cur design products
(approximately 703 bloc~s. or 88 miles of roadway ).
Micro-surfacing requires highly specialized construction equ ipme nt Based on our last six years of experience . we
know that the use of continuous micro-surfacing equipment produces a supenor product when compared to that
applied with truck-mounted lype mac hi nes . Continuous equ ipment provid es consistency of application and
minimizes seams by reducing equipment stops and starts . Truck-mounted equ ipment was used in the
constructio n of our earlie r slurry products . Continuous micro-surfacing equ ipme nt can apply standard slurry
products while standard slurry machines are not capab le of apply ing icro-surfacing . The number of continuous
micro-surfacing machines co nt inu es to grow throughout the country: SASS owns an~ operates two of these
mach ine s. BASS has successfull y constructed micro-surfac,ng on sellected arteri als , co l:-.:tors . industrial and
local serv ice streets in uur 1991 , 1992 . 1993. 1994 , 1995, and 1996 rrm:ro-surfacing programs .
Slaff continues to monitor slurry seal and micro-surfacing activities in cne metto area . The workmansh ir, of BASS ,
Inc .. particularly with micro-surfac in g, appears to remain superior Mocn inccinsisten cy exists in the mix designs
used by others in the metro area , although many jurisdictions ar, • agan requ1n11g the gray gran ;te aggregate that
we have specified since 1987 Many other user agenc ies continue tc modify their specifications, sugg esting that
they are not completely sat isfied with earl ier products . We have observed areas of iocalized fa ilure in micro -
surfac'ng products placed by others dunng 1992 an d 1993, 1ndicabng t>nly marg inally satisfactory results .
appears that many other cltles continue to settle for •l.'.lndard slurry prr,d11cts lnstel!<l of micro-surfacing . This
can be partially attrib\Jted to local contractors recommending and tef,1.:t11 ,,; lower priced , lesser quality
aimponents under competitive bid conditions . Also , alurry prod I,ct1 r~~~ to be r.iors user-friendly during
llX>IIS1ructlon than micro-surfacing . It 1hould be nolltd that micro !.utfr·.,r,1 has construction lldvanta~• ovor
slJJrries in that micro can be used for rut filling and :, velil1<J In addition o providing the 1urface seal a 1d ,,..,
~ng surface that is obtained witlt standard 1lurry •p:,tl:;:.\!J<JS .
roughout our ten year experience with "Englewtod" slurry , mlcro-surfa~lng , and BASS , Inc., cillze •, response
a,nbnues to only q11estion our not including more !ttreels in our annual micro-surfacing programs .
~rience with applying our product is crucial to a successful project. We continue to monitor and evaluate slurry
and micro-surfacing contractors In the Denver area, and we may chooae lo recommend others for future years
'tll0!1<, depending upon their performance on other projects . However, our local choices remain extremely limlted
at this ti me .
Vance Bros ., Inc. of Kansas, had establls~C!'d a Oen ·;er office, snd In 1993, constructed a Littleton micro-surfacing
dBmonstration project. with marginal resulis . Va;,-, Bros . had s.>me less than satisfied slurry custor:,ers in 1994,
and the ir key Co:orado coordinator left their em,~,., it. ~drly 1995 . Vance Bros . closed the ir Denver office in late
995.
lnlermountain Resurfacing , Inc. (IMR ) remains in the slurry market, and rumor has it that they are attempting to
enter the micro-surfacing market with continuous lype equipment. Englewood had a contract dispute witlt th is
,company in 1986-1987. Using older truck-mounted equ 1pment, their micro-surfacing experience with the Colorado
Department of Transportation (Coon on Belleview fl•.·., ,ue was less than satisfactory . In an earlier COOT micro-
surfacing pro]'!::! on 1-25, in Pueb lo , IMR sublet prod ,pplication to another contractor , with very discourag ing
,esulls. Wh ile we will continue to monitor the activiti•' ~r this company , we have not been impressed with their
;,erformance lo dare , and are concerned that they are no longer members of the International Slurry Surfacing
• Association (ISSA the organization thal has estab li shed all cunrent industry standards .
•
uality Resurfacing Company of Commerce Cily is the newest slurry contractor in our area . Th is company was
established in 1994 , and lhe prin ci pa ls appear to have many years experien ce in the general pav ing ind ustry . This
company uses lare model truck-mounted lype equipment and appears to ha Je successfu lly tackled severa l
s:an dard slurry projects during the 1994, 1995, and 1996 sea sons . They do not have conti nuo us micro-surfacing
equip ment or experience plac ing our temperamental Englewood micro-surfacing prod uct. W• will also monitor the
performance of th is company and may , depend ing on the qualily of their work on other proj ects , wish to consider
o,e m for future work in Engle wood .
We prefe, to use the only con tractor that has de mo nstrated successful applications uti lizing the products and mix
designs th at we ha·,e developed , and that achieve our desired results . We are satisfied with product performa nce
ID date and are particul arly pleased with performa nc e on our local se rv ice streets. Th e contractor . BASS , Inc ., is
available to accompl ish our 1997 project in late May or early June this yea r.
Our 1997 Micro-surfacing Program will ta rget local serv ice and collector streets . We co ntinue to specify micro-
surfaci ng over standard slurry because of its ftex ibil ily of use . Slurry seal Is a single thickness appl ication product
Micro-surfac ing has the capabilily of being app li ed in whatever thickness necess aa, to add ress our maintenance
requiremeo 1s. Micro-surfacing is used for rut filling and leveling as well as for overall roadway sealing . In ea rty
years. che mical makeup caused a 17 second break time with our mic ro-surface specificati on. Mod ification in
prod uct ch em istry in 1993, 1994 , 1995 and 1996 increased break time to about 40 seco nds . Th is grea tiy
m proved the workabil ily of the mix wh il e maintain ing our ab ili ly to open streets to throu gh traffic in 20 to 30
mmu tes . if requ ired .
Our desig n con tin ues to specify the qual ity custo m crushed , gray gran ite aggregate su pp lied by Asphalt Pav, ,g
Compa ny, Golden , Colorado . We will con tinue to use the improved EAG ON em ulsion , as dev el•iped for ou r 1393,
1994 , 1995. and 1996 program s. However . our specified EA GO N emu ls ions are no longer manufact ured in the
Denv er area. In 1997, as in 1995 an d 1996 , emu lsions must be tra nsporte d from Wa co . Texas .

FINANCIAL IMPACT
We expect thal bids for slandard s!ur,y· lio 'IM metro area , using local ex>ntractors and lower quality components
than our specifications (appn,Jdmaaly 5 hour traffic timM), should range from $0 , 70 lo $0.95 per squani yard In
199'!. Quick NI, polymer-modified slumes wiltl characleristics similar lo our specifications (2 lo 3 hour traffic
times) will likely bid at $1 2510 $1 .35 penquare yPJd . The City of Greeley appears lo be the only Fronl Range
City specifying products :;imilar to 01n. Th'.lir 1993 bid price was S1 .23 per square yard . A competilive bid for a
micro-surfacing demonslration p,ajecl ""' :~3. in b'le City of Littleton, was in the S1 .65 per square ya'd range .
Littlelon may again lry a mlc:rtHurfac:ingoemonstration project in 1997 . With ou r specified qual ity emulsion,
aggregale , and application equipmen~ our comparabl11 coverage cosl in 1993 , 1994, 1995, and 1s: Ii averaged
s1.2a per square yard .
Preliminary conversations with BASS so,west a willingness to return to Englewood In 1097 and construct micro-
surfacing al a unil price comparable le last year's conlract ($161 .18 per Ion)', even tho ugh ineeases in the price
of aggregate and emulsion could run 4" to 5% ovar 1996. The 1991 contract was for $280 ,000 (approximately
160,000 square yards or60 blocks -Sf .15 per square yard -and Incl uded heavy application ra te on Soulh
Broadway ). Funding for 1992 was lmllad to $260,000 for micro-surfacing (approximately 185 ,000 square yards or
70 blocks -$1 .41 per square yard). I 1993, we cons~ approximately 201,000 square yards (76 blocks) at
a cost of $305 ,r-n •• $1 .52 per square yard. In 1993, rut fiHing , surface leveling and slightly incre ased application
rates generated a higher per square yar:tl construction cost than ou r 1992 experience. Our 1994 experience was
aga in In the $1 .50 per square yard ra,,ge , bas&d upon 207,000 square yards of product and a contract price of
$315 ,000. In 1995 and 1998, ,nil map, inc:'ealies In costs of materials and an approximately 20% increase in
applica tion ralss to do heavy ".II tilling and ieYeling , we placed 209 ,000 square yards of micro-surfacing al a lolal
cosl of $339 ,000 -$1.&2 per square yard -and 223 ,000 square yards al a lolal cost of $358 ,000 • S1 .61 per
square yard -respeclively . This axst remains in the ma,gnitude of 40% of the cost of asphallic concrete overlay
while still allowing us to correct many cflthe irregularities within a structurally sound roadway surface . Increases
incurred In 1997 micro-surfacing consc:uction and material costs would also be reflected in construction cosls for
3spha lti c concrete ove rlays in 1997.
For the 1997 prog ram , we recorrmenc; m ntractin g with BAS S, Inc. for approximately 235 ,000 square yar ds of
mic ro-surfac ing at a un~ price comparable to that negotiated in 1996, resulting in a contract of approximately
$380 ,000. $645 ,000 is available ., the oad and Bridge PIF account for 1997. The balan ce of funding in the 1997
Road and Bridge PIF accou nt wil be ui:mzed lor asphaltic concrete overlays by Englewood forces , and assoc ialed
mainlenance program adm in1str.mon. rzsting program stud ies 3nd inspecti on . Additionally, in 1997, Eng ineering
will continue discuss ions with BASS , Ct>b~. and Koch Materials to evaluate the development of new slurry and
micro-su rfacing product designs. inc!udmg ing some local aspha lt products . This effort is lo orov ide
Englewood with qual ity , cost effeclive slurry and micro-surfac ing products for future yea rs ' programs .
LIST OF ATTACHMENTS
For your information , lh e attached lists streets proposed fo r inclusion in our 1997 overlay and micro-surfacing
programs . They are intended to be reoresenta : ,e of the proposed programs and are , of course. subject to your
review and comment Since 1987, w" have addres sed the mainlenance needs of some 88 mil es of our
approx imately 120 mile roadway systam. The 1997 program will add aboul anolher 12 miles to that total.
Consequently , many deserving ma intenance candidates exist with in our streel system . A progressive slurry
seal/micro-s urfac ing program would aodress all of the streets with the sy stem over a seve n year pe riod,
suggestin g that the annua l budge'. for :n,s aaiv,ty rema ins at approx imately 60% of idea l funding levels .
