Tenders Are Invited For Construction And Modernization Of Roadsides In The Baranów Commune - Central Communication Port Investment Program. Stageii. 2024-2030, Part Of The Cpk Program Is The Social And Economic Program

1. The Subject Of The Construction Project Is The Modernization Of The Shoulders Of Municipal Roads, Which Will Allow Their Surface To Be Adapted To The Requirements Allowing The Use Of Vehicles When Performing Evasive Maneuvers, Especially With The Road Cross-Section - Single-Lane, Two-Way, When It Is Not Possible To Do So Due To The Reduced Road Width. The Purpose Of Modernizing The Roadsides Is To Increase The Safety Of Road Users.2. Existing Condition: Based On The Review Of The Existing Technical Condition Of Municipal Roads, Large Defects And Depressions In The Ground Roads, Partially Reinforced With Aggregate, Were Found. This Condition Poses A Threat To The Safety Of Road Users. On A Large Scale, This Applies To Single-Lane, Two-Way Roads Where, Due To Restrictions In Land Development, The Existing Road Width Has Been Narrowed And The Shoulders Are Used For Vehicles To Avoid/Avoid Each Other.3. Design Status: The Project Assumes The Reconstruction Of The Roadsides In A Way That Will Enable The Road Body To Be Adapted To The Terrain Conditions. The Project Assumes The Strengthening Of The Roadsides To Achieve Their Maximum Sustainable Load-Bearing Capacity. Due To This, Technological Solutions Have Been Planned, Consisting In Strengthening The Roadsides Using Geosynthetics And Stabilizing The Structure With Aggregate. The Adopted Design Parameters With The Given Values ​​Are Adapted To The Existing Width And Course Of The Road And To The Existing Terrain Conditions.4. Scope Of Works: The Project Envisages Modernization Of Municipal Roadsides Using Two Separate Technologies Constituting Two Separate Tasks. Task 1: Technology Of Strengthening Municipal Roadsides Using Geosynthetics. Designed Roadside Surface Structure: The Roadside Structure Consists Of: 1) A Cutting Layer Separating The Native Soil From The Supporting Layer Of Non-Woven Geotextile With A Strength Of 16-25 Kn/M,2) A Supporting Layer Of 20 Cm High Cellular Geogrid With A Cell Size Of 200X240 Mm, Anchored In The Ground, Filled With A 25 Cm Thick Aggregate Mixture To Achieve The Is Index ≥ 0.98. The Scope Of Works For The Construction Of The Roadside In This Technology Includes: - Construction Of A River Bed (Earthworks) Up To 25 Cm Deep With Profiling - Adding Base Of The Assumed Transverse Slope - 6%÷8% And Compaction, - Laying A Cut-Off Layer Of Geotextile On A Profiled Base, - Installation Of A Cellular Geogrid With A Height Of 20 Cm, - Making A Backfill Layer Of The Cellular Geogrid With A Mixture Of Aggregate With A Grain Size Of No More Than 0/50 Mm, 20 Cm Thick, With Compaction Until The Is Index Is ≥ 0.98. - Laying The Top Layer Up To 5 Cm Thick Made Of Aggregate With A Grain Size Of No More Than 0/50 Mm - Profiling The Slopes Outside The Roadside. Task 2: Strengthening The Roadsides Of Municipal Roads With Aggregate - Removing Etchings From The Roadside Surfaces - Loosening The Existing Roadside Aggregate Surface, - Supplementing The Roadside Surfaces With 0/31.5 Mm C
