PAVED ROAD IMPROVEMENT PROJECTSConcrete Panel ReplacementsSharidan Hills SubdivisionConcrete panel replacement is anannual maintenance project that removes and replaces individual, distressed concrete panels - first withfilter fabric, then base rock, rebarand finally new concrete. This is aproactive approach that restores theoverall integrity of the road and maydelay the need for more extensiverehabilitation by many years.Asphalt Overlay Preparation—Golf ViewGardens SubdivisionIn preparation for an asphalt overlay, crewscomplete dig out repairs, replace culverts,accomplish shoulder and right-of-way work,etc. In 2014, this comprehensive preparation was applied to roads, Pin Oak Blvd,Golf Blvd, and Locust Grove Dr. in the GolfView Gardens subdivision. Implementingthis approach before an overlay preservesand improves the paved surfaces by reducing the possibility of future sub-grade failures.Prep Work: Dig Out Repairs Step by Step Saw and excavate 12 inches deep Filter fabric is installed in the sub gradeto keep pavement breakdowns from occurring Six inches of surface rock is distributedon top of the fabric Two 3” lifts of asphalt are installed andcompacted between lifts3

RURAL ROAD IMPROVEMENT PROJECTS — NORTH AND SOUTH BOONE COUNTYReplacing Culverts—Improving drainageacross northern and southern BooneCountyNumber of crossroad culvertinstallsNumber of CulvertsBCPWs “proactive instead of reactive” mainte100nance strategy, has resulted in an increase ofcrossroad culvert installations over the past50three years. The Rural Road Improvement pro0gram, already in place, establishes regular main2014 2013 2012tenance cycles of ditching, profile crowning,grading, etc. In collaboration with the engineering division, specific locations were targeted for culvert replacements and new culvert installations.Replacing crossroad culverts improves drainage and the overall condition of the road. The crossroad culverts installed are poly-coated pipes and have a lifespan of 30-50 years.The blue line featurerepresents a crossroadculvert on Low CrossingsRd. Each culvert is identified by a unique valuewhich facilitates trackingand organization of information.Replacing crossroad culverts along Old Plank RdTwo crossroad pipes were replaced on Old Plank Rd justsouth of Smith Hatchery Rd. this past year. One of the culverts had collapsed due to a tree root growing inside thedrainage structure. TheTree root that was in culvertnew pipe installed in thislocation, was slightly larger than the original. Thelarger pipe will help withdrainage for this area andkeep the road in saferdriving condition.Using Technology to Track Culvert InstallationsRoad Maintenance Superintendents useArcGIS For Mobile mapping software tolocate where the culvert install will takeplace. Tracking the information in a mapping application allows management tovisualize where the culvert will be installed and include new attribute information for that new culvert.New Culverts:48” barrel, 44 ft in length96” barrel, 50 ft in length4

BRIDGE DECK SEALING PROGRAMIn 2010, the department initiated a preventative maintenance program to protect BooneCounty bridges from deterioration caused by weather and saltused for ice control. In 2012, webegan a work plan where crewscleaned and sealed 37 bridges.In 2013, a regular 3-year rotation of preventative maintenance was implemented to keepthese bridges in top condition.Compared to roads and culverts,bridges are more expensive tofix, therefore preservation provides a significant cost benefit.Geospatial technology is used toplan and prioritize bridge maintenance. This is an effective tool toidentify the bridges targeted forsealing in the 3-year rotation. Thisbridge on Burr Oak Rd will be resealed in 2015.Each point on the map represents the bridgesthat were power washed and sealed for 2012,2013 and 2014. For the 2015 year, the bridgesin the SE and SW quadrant of Boone Countywill be completed.What kind of sealantis used?The sealant used forBoone County concrete bridges is anenvironmentallysafe, penetratingsealer that is sprayapplied to the surface to seep into theconcrete and providea protective barrieron the bridge deck.How do we deck seal?Bridge deck sealing consists of two steps. Thefirst step is power washing the bridge to removeany dirt, aggregate, orexcess residue that maybe on the bridge. Thesecond step isdistributing the sealanton the bridges to keep itfrom deteriorating.Quick Fact: There are 128concrete bridges in BooneCounty.5

During an emergency storm response event, Boone County Public Works road crews and sign technicians putall other projects on hold to respond to severe weather. When a storm hits Boone County, roads and bridgesare affected due to flash floods, lightning, and strong winds. Because Public Works employees are officiallyregarded as first responders , they have an important role in planning, preparing and responding to disasters.Road crews will inspect roads during these events and communicate back to the public works office which intersections are impassable or closed. This information is then reported to Boone County Emergency Management.FLOODED ROADSWIND DAMAGEVEGETATION DEBRISLeft: Woodie Proctor Rd BridgeRight: Fox Hollow Rd Low Water CrossingEmergency storm response events occur across BooneCounty every year. Each one of these point locations represent acombination of, clearing vegetation debris from bridges, cleaningout driveway and crossroad culverts, removing fallen trees fromthe middle of the road, replacing traffic control signage and setting up flood advisory signs. During a storm event, these tasks areprioritized to allow emergency vehicles to access the roads if necessary. Several days after the storm has occurred, crews continueto spend 15-20% of their time completing these tasks due to thelocation of these affected areas.6

RESPONDING TO WINTER WEATHERPRIORITY ROUTES AND EMERGENCYRESPONSESDuring the initial phase of a majorsnow event, nearly all resources arededicated to keeping priority roads(paved surface roads that serve critical facilities and provide access between state highways and communities) open. Paved roads are treated with a salt mixturethat prevents the snow and ice from bonding and sticking to the road surface.GRAVEL ROADSGravel roads are primarily cleared bygraders, which operate during daylighthours. Once snow has stopped, ittakes approximately 3 complete 12hour shifts to make a pass over allgravel roads. Motor grader operators take windrows ofexcess rock and distribute it along the roadway creating more traction for motorists.SUBDIVISIONSThe main streets within the subdivisions are often cleared by our largedump trucks with follow-up on theside streets and cul-de-sacs with ourone-ton trucks.When a winter storm isforecast for the area,BCPW will have employees and equipmentstaged and ready tobegin clearing the 800 miles of county roads.For a major snow/iceevent, all 40 drivers arescheduled to work 12hour shifts around the clock. Equipment available for snow removal includes: 16 dump trucks, 5 one-ton trucks, and 8 graders. The overall effectiveness of the snow removal effort is enhanced by an organized, consistent approach to the task.POLAR VORTEX AFFECTS BOONE COUNTY PUBLIC WORKSBattling any winter weather event is a huge challenge, especiallywhen extreme cold temperatures are present and visibility is lowdue to blowing snow conditions. This is what BCPW experiencedWinter 2014. Due to a polar air mass that blanketed most of thecentral Midwest, where temperatures were several degrees belowzero for multiple days, BCPW experienced frozen fuel lines, difficulty with equipment and ineffective salt mixtures. At subzerotemperatures it is too cold to use salt mixtures effectively. Refreezing, causing more hazardous conditions, is too much of a risk.Snow and Ice Operations 2012 - 2014800000700000600000CUL-DE-SACS AND DEAD-ENDSTREETSCul-de-sacs are at a disadvantagewhen it comes to snow removal because snow plow drivers are facedwith the problem of maneuverabilitywithin the cul-de-sac as well as limitedoptions for depositing the extra snow.These streets are addressed after thehigher volume roads.Sources: climate.missouri.edu, 000003000002012200000201310000020140Labor HoursLabor CostEquipmentMaterial CostCostTotal CostThe chart above displays hours, labor, equipment and material costfrom 2012 to 2014. Because 2014 showcased multiple record breaking winter events, more time and money were dedicated to snowoperations. Our snow crews are dedicated and work very hard serving the citizens of Boone County and will continue to do so.7
