Tenders Are Invited For Renovation Of The Access Road To Agricultural Land - Dąbrówka in Poland

Work Detail

The Subject Of The Order Is The Renovation Of The Municipal Road Access To Agricultural Land - Dąbrówka, Covering Plots No. 260, 264, 265, 16/2, 17/4, Dąbrówka District, Paradyż Commune. The Section Of The Road Covered By The Study Starts At Km 0+000 And Ends At Km 0+743. On The Entire Section Undergoing Renovation, The Road Has A Variable Width Of 2.50-4.50 M. The Cross-Section Is A Road Cross-Section With A Dirt Surface And Roadsides On Both Sides. The Road Is Not Lit, And Access To The Road From Neighboring Plots Is Via Existing Individual Exits. Designed Land Development Throughout The Section Undergoing Renovation, The Road Shows Signs Of Degradation (Deformation, Unevenness, Defects), Hence The Surface Reinforcement Of The Existing Surface Was Designed, Maintaining Its Width Of 2.5-4.5 M. The Roadsides Were Designed As Reinforced With Crushed Aggregate, 0.3 M Wide. Normal Cross-Sections. On Straight Sections And Horizontal Curves With A Radius > 220 M, The Transverse Slope Of The Road Was Designed To Be 2% Roof-Shaped And 6% For The Shoulders. On Horizontal Curves With Radii <220 M, A One-Sided Transverse Slope Of The Road Was Designed, 2% Towards The Inner Edge. Longitudinal Profile. The Entire Road Section Was Adapted To The Existing Road Surface, Taking Into Account The Need To Strengthen And Adjust It In Order To Obtain The Required Slopes. At The Beginning And End Of The Study, The Gradeline Was Connected To The Height Of The Existing Surface. Construction Of Road Elementsroadway: - Wearing Surface Made Of Ac11s Asphalt Concrete, Thickness. 4 Cm.-Equalizing Wall Made Of Ac11w Asphalt Concrete, Thickness. Wed. 4Cm-Substructure, Lower Wall, Thickness. 15Cm Made Of Crushed Aggregate 0-63Mm - Substructure In The Upper Upper Part Thick. 8Cm Made Of Crushed Aggregate 0-31.5Mm Roadside Reinforced With Aggregate And Dirt Slopes: - Roadside Surface Made Of Crushed Aggregate Stab. Down. 0/31.5Mm Thick 10 Cm. - The Surface Of The Exits Is Made Of Native Soil. Additionally, Reconstruction (Expansion) Of The Ordinary Exit Is Planned. The Gradeline And Exit Profile Will Be Adapted To The Existing National Road Surface And Accompanying Infrastructure. The Designed Facility Was Located As Shown In The Graphic Part Of This Study, Prepared Using A Permanent Technique On The Current Situational And Elevation Map. Discharge Of Rainwater From The Surface Of The Planned Exit As Part Of The Existing Surface Water Runoff System Within The Road, In A Way That Does Not Cause Flooding Of Neighboring Plots And The Road Surface. The Elevation Of The Terrain Will Not Change. The Designed Structure Of The Exit - A Surface Made Of Concrete Cubes. 8Cm; - Cement-Sand Bedding 1:4 Gr. 3Cm; - Basic Subbase Made Of A Mixture Unbound With C90/3 Grit Aggregate. 20Cm; - A Layer Of Improved Subgrade Made Of A Cement-Bonded Mixture C1.5/2, 15 Cm Thick; Parameters Of The Designed Exit - Road Width 4.50 M, - Intersection Of The Edge Of The Exit Surface And The Road Made With A Ro
