Tenders Are Invited For Reconstruction Of The Lipinki-Bielice Municipal Road

The Subject Of The Order Includes Construction Work Entitled: Reconstruction Of The Lipinki-Bielice Municipal Road. The Reconstruction Involves The Renovation Of The Existing Bituminous Surface After The Existing Asphalt Trace Within The Plots Covered By The Investment And The Construction Of Roadsides Made Of Crushed Aggregate. The Scope Includes Milling The Existing Surface On The Entire Road Surface To A Depth Of 4 Cm, Making A 4 Cm Thick Binding Layer And A 3 Cm Thick Wearing Course, Laying Mesh, Sliding Layer On The Section Of Cracks And Construction Of Roadsides. The Designed Situational And Height Solutions Were Adapted To The Existing Road Course And The Available Width Of The Road Plots Covered By The Investment. It Is Assumed That The Existing Road Course Will Be Maintained Along The Existing Asphalt Track With A Width Of 2.78 To 5.30 M. On Straight Sections, A Roof-Shaped Transverse Road Slope Of 2.0% And A Shoulder Slope Of 8.0% Are Planned. On Horizontal Curves, A One-Sided Transverse Slope Of The Road Is Expected To Amount To 2.0%, While The Roadsides Will Be 2.0% On The Outside And 4.0% On The Inside Of The Curve, Respectively. It Is Planned To Maintain The Existing Road Grade, Without Introducing Any Significant Changes To Its Elevation. Only Local Adjustments To The Height And Longitudinal And Transverse Slopes Are Allowed, Necessary To Ensure Proper Surface Drainage Of Rainwater And Meltwater, While Maintaining A Smooth Connection To The Existing Land Development. Construction On The Existing Road. The Entire Section Is Expected To Be Milled To A Depth Of 4 Cm. After Preparing And Cleaning The Substrate, Make: • A Wearing Course Of Ac 11 S Asphalt Concrete - Thickness. 3 Cm;• Binding Layer Of Asphalt Concrete Ac 16 W – Thickness. 4 Cm;• Reinforcing Mesh,• Existing Pavement Structure After Milling;The Required Cleaning And Interlayer Sprinkling Should Be Performed Between The Bituminous Layers. On The Road Section From Km 0+987.70 To Km 1+591.33, There Are Numerous Transverse Cracks In The Existing Bituminous Surface. In Order To Limit The Transfer Of Cracks To New Asphalt Layers, It Is Planned To Create A Sliding Layer Of Mechanically Stabilized Crushed Aggregate With A Thickness Of 15 Cm After Compaction. This Solution Is Designed For A Total Length Of 400 M, In Places Where The Greatest Damage To The Surface Occurs. After Milling The Existing Surface, A Sliding Layer Should Be Made, And Then A Binding Layer Of Ac 16 W Asphalt Concrete, 4 Cm Thick, And A 3 Cm Thick Ac 11 S Asphalt Concrete Wearing Course Should Be Laid. The Location Of The Sections Covered By The Sliding Layer Should Be Taken In Accordance With The Design Documentation, Taking Into Account The Existing Technical Condition Of The Surface. Sides: Both Sides Of The Shoulders Are Designed To Be Made Of Crushed Aggregate. 0/31.5 Mm With A Basic Width Of 0.75 M And A Thickness Of 20 Cm After Compaction. In Places Where The Width Of Plots Is Limited, The Roadsides Are
