Today’s Agenda Project Description & Approach Alternative Solutions Final Design Results –Proposed Roadway –Horizontal & Vertical Alignment –Pavement Design –Hydraulic Design –Construction Plan –Cost Analysis Summary - Q & A

Project Description 13-acres of land Multiple curves in the road, storage buildings, railroad tracks and other outdoor storage 0.6-mile road connects the main access highway to the storage facility Recent changes in ordinance transport have brought up this issue

Project Description Challenges –Railroad crossings must be limited –Crossing can not be over a “frog” –Road must meet Navy, INDOT, and AASHTO codes and regulations

Project Approach Site Assessment - walkthrough, site survey, map overview Existing Subsurface Conditions - Soil assessment - Boring samples from ATC Associates Codes and Regulations - challenges - must comply with Navy, AASHTO and INDOT codes and regulations

Project Approach Assessment of Design Constraints –Wildlife protection, subgrade conditions, hydrological issues Design –Consider possible alternatives –Design appropriate solution based on criteria

Alternative Solutions Five alternative solutions Developed by RH Roadways with suggestions from client & faculty Created Evaluation Matrix Design of best alternative

Alternative 1 – Existing Road

Alternative 2 – Modify Existing Road

Alternative 3 – New Alignment South

Alternative 4 – New Alignment North A

Alternative 5 – New Alignment North B

Evaluation Matrix

Comparison Existing Roadway Roadway conditions fair/poor 7 RR crossings 85-feet radius of curvature 10% maximum vertical grade Little signage Proposed Roadway Excellent roadway conditions 5 RR Crossings 500-feet minimum radius of curvature 3% maximum vertical grade Proper signage (posted 25mph)

Comparison Existing Roadway Lack of pavement markings Width of 16-feet Average thickness of 4-inches Proposed Roadway Adequate markings (centerline, edges, etc.) Width of Road 24-feet with shoulders and ditches Pavement total thickness of 10- inches

Pavement Design Computed an Equivalent Axel Load (EAL) –Traffic Study – 200 trucks per day each way –Used traffic data and tractor trailer dimensions and weight for EAL design Million EAL –Calculated Stacker EAL – insignificant Pavement Thickness –CBR value from ATC Associates + EAL –Asphalt Institute Manual to design 4 options

Pavement Options Option1: 2” Asphalt Concrete Surface 9” Asphalt Concrete Base Option 3: 2” Asphalt Concrete Surface 8” Asphalt Concrete Base 6” Untreated Aggregate Subbase Option2: 2” Asphalt Concrete Surface 15” Type III Emulsified Asphalt Base Option 4: 2” Asphalt Concrete Surface 13.5” Type III Emulsified Asphalt Base 6” Untreated Aggregate Subbase

Pavement Cost Data collected from INDOT website detailing their project costs for HMA costs include labor and equipment.

Final Pavement Design 2” Asphalt Concrete Surface 8” Asphalt Concrete Base 6” Untreated Aggregate Subbase

Hydraulic Design Place 3 culverts –Corrugated Metal Pipe – 12” Diameter Ditches –Flow of 1.27 cubic feet per second –Depth = 0.5 feet –Slope = 3:1

Culvert Locations

Construction Alternatives Traffic Control - Three Options Method 1: –Complete shutdown of road with a detour to divert traffic during construction Method 2: –Shut down one lane while remaining lane stays open for traffic flow Method 3: –Same as method 2, save an added detour to ease traffic flow through the project area.

Traffic Detour Route

Erosion & Sediment Control Plan Erosion control points of interest: –Minimum clearing and grading –Minimum erosion due to short project time –Runoff is non-existent – no present streams –After bare soil removed, silt fences will be needed along sloped areas –Upon project completion, areas must be seeded and slopes protected with erosion control blankets in place

Soil Management Borrow location Location for cut soil to be stored “Phase-construction” Topsoil stockpiles Soil testing required according to AASHTO and INDOT Specifications

Waste Management Large capacity worksite dumpsters Construction fencing Planned stockpiling Pavement removal ~2500 yd^2
