Tenders Are Invited For Overhaul Of Stara Planina Street - Second Stage Of 84-91-83-90-92-94-95-96-235, Kotel in Bulgaria

Work Detail

The Street Has An Asphalt Surface, And Its General Condition Is Poor. Gaps, Holes And Cracks Are Observed. There Is No Horizontal Marking, Which Makes It Extremely Difficult For Moving Vehicles. Curbs Are In Poor Condition - They Are Not In The Design Position Or They Are Destroyed. The Pavement Is In Poor Condition, As In Some Places The Necessary Transverse Slopes Are Missing And Not Provided, Which Makes It Difficult For Pedestrians To Move. Drainage Is Poor, With Surface Water Retention And Puddle Formation Common. This Project Will Ensure: Restoration And Improvement Of The Transport And Operational Qualities And Load-Bearing Capacity Of The Road Surface; Ensuring Traffic Safety Conditions; Improving Drainage; Improvement Of Pavement Areas; Construction And Replacement Of Existing Curbs; Providing An Accessible Environment, Including Improving Access For People With Disabilities. The Geometric Solution Made Is In Accordance With The Existing Situation, And Only In The Places Where The Gauge And The Surrounding Development Allow, The Technical Characteristics Of The Route Have Been Improved. The Gauge Of The Traffic Lane Includes 2 Traffic Lanes. The Leveling Solution Is In Accordance With The Existing Position Of The Entrances Of All Buildings, Including The Garages. The Cross Slope Of The Road Lanes Is 2.5%, And The Sidewalks Have A Slope Of 2% To The Traffic Lane, Where They Allow. Along The Entire Route, The Cross Slope Of The Roadway Is Two-Sided, Except For: Section From Km 0+480.00 To Km 0+560.00 Km; Section From Km 0+650.00 To Km 0+670.00 Km. In These Sections, The Slope Is One-Sided From Left To Right, As The Mileage Increases. The Surface Drainage Of The Traffic Lane Is Carried Out Along The Given Longitudinal And Transverse Slopes. The Following Measures Are Planned To Improve Drainage: Cleaning, Raising Or Lowering Of Existing Ua (Рш) And Дш; Repair Of Existing Line Drains - Replacement Of Grates, Cleaning, Raising Or Lowering; New Linear Drains - 3 Pcs. Load Class D400 According To Bds En 1433; New Concrete Curbs 18/30/50, Which In The Case Of Curb Curves Will Be Executed Lowered (Submerged); New Mas; The Following New Pavement Is Being Constructed: Asphalt Mixture For Wear Layer Type A - 4 Cm; Asphalt Mixture For The Lower Layer (Binder) - Average Thickness 6 Cm; At The Beginning And End Of The Street, In Order To Connect The New And Existing Construction, Technological Milling Of The Asphalt Concrete Pavement Is Performed And Then A Leveling Layer Is Laid. It Is Planned To Build A New Pavement Along The Entire Length Of The Sections With Variable Gauge With The Following Construction: Bechaton (Grey) – 8 Cm; Sand - 5 Cm; Crushed Stone - 25 Cm; Geotextile 200 G/M2. The Installation Of New Road Signs Ii Size And Class 2 (Ra2) Light Reflectance Is Planned. The Implementation Of Horizontal Road Markings Is Foreseen. It Is Performed With White Acrylate Paint With A Wet Film Thickness Of 0.3 Mm.
