Work Detail

Carriageway Resurfacing Works – Project To Make Forest Stands Available At Oz Gemer. The Subject Of The Contract Is The Forest Road Karafová - Skalica, Reconstruction Of An Old Dirt Forest Road With Local Strengthening To A Forest Road Of Category 2L 4.0/30, I.E. With A Free Width Of The Road Crown Of 4.0 M On A Straight Section And With An Extension In The Directional Curves For A Wheelbase Of 9 M. The Current Damage To The Road Of The Forest Road Is Mainly Track Deformation, Which Was Repeatedly Filled With Unsorted Limestone And Silty Waste From The Quarry In Tisovec. The Construction Of A Road On An Old Forest Road Is Proposed According To The Damage Of Individual Sections Of The Road. The Original Deformed Roadway With Tracks Is Stabilized With Crushed Aggregate Fr By Replacing The Subsoil In The Marginal Strips 0.6-1.8 M Wide. 125 Mm By Building A Protective Part Of The Road With A Thickness Of 200 Mm, Then The Rest Of The Road Is Reprofiled With A Cutter To A Depth Of 100 Mm And The Base Layer Is Strengthened With The Reinforcement Of The Triaxial Geogrid And The Base Layers Of Gravel In Two Fractions Of 32-63 Mm Hr=100 Mm For Wedging The Aggregate Into The Triaxial Polypropylene Geogrid. Above It, He Lays Gravel Fr=0-32 Hr=50 Mm Across The Entire Width Of The Plan, Also At The Points Of Switchbacks And Headland Turns. Subsequently, Both Gravel Layers Are Profiled With A Grader And Compacted With A Vibrating Roller With Water Sprinkling To Min. Bearing Capacity Edef2 60 Mpa. A 150 Mm Thick Abrasive Layer Of Msk Mineral-Reinforced Aggregate Is Laid With A Paver As A New Abrasive, Unconsolidated Layer Of Min. From Three Fractions Of Aggregate With A Closed Grain Size Curve Mixed In A Mixing Center Or In The Production Of Gravel And Asphalt Mixtures, Corresponds To Stn En 13 285 And Stn 73 6126 And Aggregate Stn 13242+A1. The Optimal Amount Of Water Is Determined By Proctors Modified Test According To Stn 13286-2. It Is Then Compacted With A Vibrating Roller. Transverse Drainage Is Ensured By A One-Sided Transverse Slope Of 4% On Straight Sections And A One-Sided Central Slope Of 4-6% In The Directional Arc. Transverse Drainage Of Water From The Trapezoidal Ditch Is Proposed Through Existing Culverts, But New Culverts Made Of Corrugated Hdpe Pipes Of Circular Profile Will Also Be Added. The Exact Quantity And Scope Of The Contract Can Be Found In The Project Documentation And The Measurement Report, Which Are Part Of The Tender Documents.
