Develop and design projects that identify and incorporate safety improvements. Economic considerations are also a major factor in determining the priority and scope of 3R projects.  \n3R projects include resurfacing, pavement structural and joint repairs, widening of lanes and shoulders, minor alterations to vertical and horizontal alignment, bridge repairs, and removal or protection of roadside hazards.  \nFactors influencing the scope of a 3R project:  \n1. Roadside conditions  \n2. Funding constraints  \n3. Environmental concerns  \n4. Changing traffic and land use patterns  \n5. Surface deterioration rate  \n6. Accidents or accident rates  \n3R-type improvements are normally made within the existing right-of-way but to carry out the necessary improvements, additional right-of-way may be considered.  \n3R-Design Exceptions  \nIt may be appropriate and cost effective to deviate from the following design guidelines if properly analyzed and justified. These deviations will require approval of the UDOTPreconstruction Engineer and must be supported by engineering analysis.  \nDefinitions  \nThe following definitions apply:  \nMaintenance-Maintaining the existing roadway and related appurtenances as necessary for safe and efficient operation and to control the natural deterioration of the pavement (see“Pavement Management and Pavement Design Manual”) . Design improvements are not the normal intent of maintenance operations. Pavement repairs such as seal coats, full width patching, crack sealing, thin plant mix resurfacing for sealing of the pavement surface, correcting minor surface irregularities, etc. , are generally considered maintenance activities. This work is not considered a 3R activity.  \nResurfacing-Application of a new or recycled layer or layers of pavement material to existing pavements to provide additional structural integrity or improved rideability.  \nRestoration-Rebuild or bring back the original design capability of the facility. This may include minor pavement widening, addition of paved extensions, other drainage improvements, correction of superelevation, and other safety improvements. Generally, restoration activities are confined within the existing right of way.  \nRehabilitation-Reconstruction of limited portions of the project’s length in order for the facility to better serve existing and short term traffic requirements. Additional right-of-way may be required.  \nReconstruction-Fifty percen","cbCaiuBQQ3UO0U8B","https://ap.wps.com/l/cbCaiuBQQ3UO0U8B","pdf",79189,15,"English","# Introduction\n# Design Speed\n# Alignment\n# Lane & Shoulder Widths\n# Bridge Width, Vertical Clearance and Structural Capacity\n# Grades and Cross Slopes\n# Side Slopes and Clear Zone\n# Intersections\n# Safety Enhancements\n# References","[{\"question\":\"What is the primary purpose of 3R projects in this standard?\",\"answer\":\"The primary purpose is to provide a better riding surface, enhance safety, improve operating conditions, and preserve and extend the service life of existing non-freeway projects.\"},{\"question\":\"What types of work are included within 3R projects?\",\"answer\":\"3R projects can include resurfacing, pavement structural and joint repairs, lane and shoulder widening, minor vertical/horizontal alignment alterations, bridge repairs, and removal or protection of roadside hazards.\"},{\"question\":\"How is design speed selected for 3R projects?\",\"answer\":\"Design speed should be identified for selecting appropriate design element criteria across the full section, using the road functional class and terrain character, and based on 85th Percentile Speed considerations.
