Construction Work For Highways - Execution Of Works On The Objective: Consolidation And Protection Of Slopes On Dn 7A Km 63+200-Km 86+601. The National Road Dn 7A, On The Studied Sector, In Length Of 21.932 Km (According To The Projected Axis And Topographic Measurements), Is Classified In Technical Class Iv, And From The Point Of View Of The Importance Category Is Included In Class C Normal Importance. Degradation Found Along The Entire Length Of The Studied Road Sector Are The Following: Tiles With A High Level Of Severity; Longitudinal Cracks And Cracks; Plumbers And Extended Carpets; Most Of Them Were Over 5.00 Cm; Waves; Surface Exudates; Pinches; Ceding Of Abutments; Clogged Ditches; Partially Executed Floors That Do Not Shows Major Degradation Or Defects That Do Not Allow The Continuation Of The Works. Walls Degraded Supports And Too Low Heights, With Materials Spilled Over The Crowning, A Fact That Also Led To The Massive Clogging Of Ditches; Non-Functional Barbicans; Displacement Of Sections In The Joint Area; Local Failures As A Result Of The Overturning Of The Casings And Overturning; Embankment Break Etc. The Bridges Have Concrete With A Friable Appearance; Surface Defects Of The Visible Face; Corrosion Of Fittings; Rust Stains; Reduction Element Section; Infiltrations; Concrete Segregations; The Absence Of Cash Registers, Stairs And Walled Trenches At The Foot Of The Slopes; The Bed In The Area Of ​​The Bridges Is Undeveloped And With Material Deposits. The Floors Are Mostly Unfinished But (Partially Executed) With The Structure Of Prefabricated Elements For Which The Monolithic Tympanums Were Not Cast And The Wings, The Fall Chambers Were Not Made, Etc. Planned Route: The Designed Solution Of The Planned Route Remained Unchanged With The Exception Of The Corrections To The Curves At Km 83+380 And Km 84+280, Which Were Necessary As A Result Of Connecting The New Designed Bridges. Longitudinal Profile:  Minimum Slope Of 0.1%; Maximum Slope Of 10.55%; Minimum Radius For Concave Connections Of 750 M And Minimum Radius For Convex Connections Of 350 M (Being Used In Two Locations). Transverse Profile: It Is Maintained With The Width Of The 8.00 M Platform, Of Which:  Width Of The Carriageway: 2X3.00 M = 6.00 M  Width Approaches: 2 X 1.00 M Of Which Framing Strips: 2 X 0.25 M;  Transverse Slope: 2.50% For The Carriageway And 4.00% For The Approaches. Road Structure - With The Adaptation Of The Thickness Of The Layers And The Mixtures To The Provisions Of The Regulation Regarding Hot Asphalt Mixes. Design, Preparation And Technical Conditions Commissioning Of Asphalt Mixtures. Code And 605-2016. Dimensioning Of The Structure Road Was Realized For The Perspective Period Of 25 Years And The Volume Of Traffic Calculation, Heavy 0.3 – 1 M.O.S. The Main Categories Of Work To Be Done For The Execution Of The Objective Consolidation And Protection Of Slopes On Dn 7A Km 63+200-Km 86+601 Are: - Reinforcement Of The Existing Road Structure Using The Existing Dowry - New Road Structure – Widening Boxes As Well As In The Areas Of Complete Restoration Of The Road Structure - Drainage And Evacuation Of Water - Traffic Safety - Works Of Bridges (Rehabilitation Works Of Existing Bridges And New Bridge Constructions) - Works For Strengthening Protection Of Vesrsanti: Retaining Walls Of Debleu Reinforced Concrete, Structures Of Support From Drilled Columns/Piles, In Backfill, Nets Anchored In The Slab, Wall Of Gabion Support In The Backfill, Camasuire The Existing Support Wall In The Backfill.
