Construction Of The Brześcianka - Stryki Forest Road With Technical Infrastructure In The Grabowiec Forestry - Stage Ii From Km 0+000 To Km 1+400 Scope Of Road Works: Construction Of Road Surfaces, Construction Of Passing Surfaces, Construction Of Exit Surfaces, Construction Of Intersection Surfaces, Demolition And Construction Of Road Culverts, Felling Of Trees. The Entire Planned Investment Was Presented In The Land Development Plan. It Is Recommended To Maintain The Following Sequence Of Works When Implementing The Planned Investment: Preparation Of The Area, Marking Out The Designed Surfaces, Locating The Utilities Route, Earthworks, Construction Of The Foundation, Construction Of The Designed Surfaces, Construction Of Green Areas, Cleaning Works. Road Worksthe Beginning Of The Designed Road Axis Is Assumed In The Axis Of The Existing Forest Road Passing Through Plot No. 147/2 And 153. The End Is Connected To The District Road No. 1596B On Plot No. 638 And 357. The Length Of The Designed Route Is 2,877.3 M. The Axis Consists Of Straight Elements And Circular Arcs. The Bends Have Been Rounded With Arcs With Radii From R = 70 M To R = 300 M. On The Designed Section, The Road Will Have A 3.5 M Wide Road With 0.75 M Wide Shoulders On Both Sides. Public Exits To Internal Forest Roads 3.5 M Wide With 0.75 M Wide Shoulders On Both Sides Have Been Designed. The Road In The Normal Cross-Section Has A Slope Of 4%. Drainagethe Flow Of Rainwater Will Be Ensured By Applying Standard Longitudinal And Transverse Slopes On The Designed Surfaces. At Km 0+327.8 And 0+798.60 M, Culverts Made Of Hdpe Pipes With A Diameter Of 500 Mm Have Been Designed. The Culverts Should Be Placed On An Aggregate Bench With A Thickness Of At Least 30 Cm. The Material For The Bench Must Be Frost-Resistant. Gravel And Sand Mixtures Should Be Used (Grain Diameter 0-32Mm). The Footing Should Be Constructed In The Transverse And Longitudinal Directions In Accordance With The Designed Inclination Of The Culvert. At The Top Of The Footing, Leave The Last 5 Cm Loose (Proctor Compaction Level 0.94) In Order To Recess The Notches Of The Structure. The Slopes Of The Inlet And Outlet Of The Culvert Should Be Reinforced With Cobblestones. 16-20Cm On Cement-Sand Ballast, Thickness. 10 Cm With Cement Mortar Filling (150 Kg Of Cement Per 1 M3 Of Mortar) And Filling The Joints With 15 Mpa Mortar. Paving Width 3.0 M. Paving Of The Culvert Slopes Should Be Performed Along The Entire Height Of The Slope And From The Edge Of The Shoulder To The Edge Of The Road In Order To Improve Roadside Maintenance Works During Road Operation. When Backfilling The Culvert, The Following Rules Should Be Observed: - The Backfill Should Be Laid On Both Sides Of The Culvert In Layers 10 Cm Thick; - The Backfill Compaction Index Should Be Close To 1.0; - The Backfill Soil Should Be Not Seeded, Possibly Uniform, Grain Diameter <30Mm.3.2 Location: The Place Of Implementation Of The Subject Of The Order Wil
