Pavement Messages3M Polyurea MessagesNot successful. Painted over after 1 year.
6
Energy ConservationMilford Wind TurbineWind power is a very productive and powerful resource when sited and effectively harnessed.
7
Energy ConservationMoab Solar ArrayThe system has been performing as designed
8
Energy ConservationCenterville Solar ArrayThis is by far the best example of how renewable energy and energy conservation work well together.
9
Energy ConservationClearfield Solar ArrayThe system makes good use of an old structure still being used.
10
Guard Rail/Concrete Barrier
Rubber Guardrail Offset BlockBlock is unrotated and still flexible after ten years.
11
Guard Rail/Concrete Barrier
GPS Crash Cushion InventoryA database of crash cushion locations was initiated and established.
12
Hard Surface MaintenanceHorizontal Drill RigUse this jig to simplify small scale dowel bar retrofit projects.
13
Hard Surface MaintenanceHeatwurxTM Asphalt Pavement Repair DemonstrationA specification has been developed and a statewide contract has been executed with HeatWurx.
14
Hard Surface MaintenanceWarm Mix Asphalt Using Warm WaterReg.1 is taking the lead on this evaluation.
15
Hard Surface MaintenanceWarm Mix Asphalt Using EvothermInformation given to Reg. 2 for their follow up.
16
Hard Surface MaintenanceFlexible MicrosurfacingReg.1 is taking the lead on this evaluation.
17
Hard Surface MaintenancePerma Patch on I-15Region 3 is buying what they need on a P-card and doesn't Central to create a contract.
18
Hard Surface MaintenanceFiberCrete on SB I-15 at 1300 SReg. 2 uses it quite a bit.
19
Hard Surface MaintenanceUnitex High Friction Surface CourseTraffic and Safety Division will assume responsibility of this test.
20
Litter Pick UpRoad Rake-Automated Debris RemovalAll crews that used the device recommend immediate purchase of a unit for their region.
21
Litter Pick UpLitter Picker-Automated Litter RemovalWithout refinement this machine is not suited for use on roadsides with dry brush and grass.
22
Litter Pick UpWork Force Services Work CrewThe WFS/UDOT partnership has worked well. The crew has been productive and substantial roadside maintenance tasks have been accomplished.
23
OMSMesoWest Weather Data WarehouseData is cleaned, verified, and presented in coherent statewide displays.
24
OMSFeature Inventory Data Extraction from Plan SetsThis method alone does not meet the requirements for feature inventory data extraction
25
Pavement MessagesThermoplastic Route ShieldsProduct has been shown to minimize driver confusion and be durable enough to weather one winter plowing season.
26
Pavement MessagesVisilok BeadsHelps reduce dry times, hence, track times, especially in colder weather.
27
Pavement StripingState Spec Beads and 3M Elements on SR-8The project was initially successful in demonstrating the product and method of application to our State forces.
28
Pavement StripingVisimaxTM Wet Reflective BeadsThis successful proof of concept was the foundation of subsequest research that is currently in progress
29
Pavement StripingWet Night Bead ComparisonsVisual inspection in the fall of 2013 showed the new, ungrooved water based paint with regular beads in was brighter in the rain than the wet night, year old, applications. We will reapply the test deck in another location that has a flatter profile so run-off is more consistent between product applications.
30
Pavement StripingState Spec Beads and 3M Elements On I-84Project was painted over 2 years later because groove wasn't deep enough to protect this application.
31
Signs & DelineatorsFlexible Base DelineatorsThe SHUR-TITE Delineator system works and has reduced delineator maintenance costs where it has been used.
32
Signs & DelineatorsIsland ReflectorsSuccessfully implemented as a special provision.
33
Snow FenceLiving Snow FenceLiving snow fence is a viable alternative where adequate precipitation exists to sustain tree growth.
34
Snow FenceWyoming A-Frame Snow FenceUDOT should not adopt the Wyoming style A-Frame snow fence as our standard
35
Snow FenceStraw Bale Snow FenceUse this style fence where right of way issues are critical and life cycle cost justifies. No permanent disturbance is required.
36
Snow FenceSnow Predator Snow FenceUse this style fence where life cycle cost justifies. Snow Predator fence took one tenth the effort to install and requires only tightening of the tension wires annually.
37
Snow FenceDelineator Post Snow FenceUse this style fence where right of way issues are critical and life cycle cost justifies. This system required no special tools to install.
38
Station AdministrationCell Phone Antenna BoosterNo reported benefit in mountain areas. Reception and transmission in the Sevier and Colorado River drainages was not enhanced.
39
Station AdministrationSand Bag FillerSuccessful. Share statewide.
40
Station AdministrationPetroleum-based Products Inflation ModelUDOT used the model to request budget relief for oil price increases
41
Winter MaintenanceHigh Performance SaltSalt from the Redmond salt dome performs better at lower temperatures.
42
Winter MaintenanceSpreader Empty Belt AlarmSuccessful. Share with other sheds.
43
Winter MaintenanceMobile Fog Dispersal "Fog Busters"This concept is valid and net savings are immediately realized.
44
Winter MaintenanceSimple Spreader CalibrationSpreadsheet and procedure are easy to use and greatly simplifies calibration
45
Winter MaintenanceGround Speed Spreader ControllersGround speed controllers work and are viable
46
Winter MaintenanceMesoWest Weather Data WareHouseMesoWest serves UDOT data to the public within 2 minutes of transmission.
47
Winter MaintenanceHigh Capacity Anti Icing TankerThe 5000 gallon tanker reduces deadhead time, adds an additional vehicle to the winter maintenance fleet, and reduces time required to treat I-15 prior to winter storms.
48
Winter MaintenanceRock PlowThis concept is valid and net savings are immediately realized.
49
Winter MaintenanceWing Plow Guidance SystemSuccessful. Share statewide.
50
Winter MaintenanceVitrified Expanded Shale Road GritVitrified expanded shale road grit is an acceptable traction aid. Use is dependent on delivered cost at the point of use.
51
Winter MaintenanceMaterial PrewettingPrewetting works as previously demonstrated by Michigan DOT in nationally published studies.
52
Winter MaintenanceJOMA Snow Plow BladesUsing JOMA blades has reduced the number of blade changes needed per truck on a statewide basis.
53
Winter MaintenanceTow PlowThe devices have been problem free and are responsive and straight-forward to operate for experienced drivers.
54
Winter MaintenanceSpreader Calibration SystemThe Scale-Tecâ„¢ Calibrator system is cost effective and simple to use with minimal training. We recommend continued use of this system for calibrating dry material spreaders
55
Winter MaintenanceRoad Condition CameraInstall additional cameras as locations and funding are identified by station supervisors and region managers
