Tenders Are Invited For Maintenance Of Forest Roads And Fire Access Roads In The Krosno Forest District In 2024.

Material Scope For Package I: The Scope Of Development Of The Maintenance Of Fire Access Road Surfaces Includes The Following Roads: Kwadratowa On The Length 7127M, Na Ślepy Passage In Length. 9307M, For Husband And Wife For Debt. 5740M. Roads - Fire Access Roads Are In Various Technical Conditions, Depending On The Intensity Of Use. During The Field Visit, Surface Damage Was Measured And Counted. For Quantitative Analyses, The Average Size Of The So-Called Damage Was Assumed. Pothole In The Surface 40*40*5Cm. It Is Planned To Carry Out Maintenance Of The Surface By Performing The Following Activities: - Breaking Up The Pothole Area With A Pick, - Removing Loose Aggregate, - Filling The Gaps With Natural Crushed Rock Aggregate With A Continuous Grain Size Of 0/31.5 Mm (Preferably From A Raw Material Identical To The Top Layer Of The Surface), - Backfilling With Stone Fines. 0/5Mm Fraction In The Amount Of Approx. 15Kg/1M2 (The Cavity Filled With 0/31.5Mm Aggregate), - Pouring Water Over The Filled Cavity And Compacting It With A Roller Or Compactor. After Filling All The Defects In The Road Surface Using The Method Above, The Entire Road Surface Should Be Uniformly: - Sprinkled With 0/5 Mm Stone In An Amount Of Approx. 10 Kg/1 M2, - Compacted Again With A Roller. Square: 1,709 Potholes Over A Length Of 7,127 M, I.E. 273.44 M2 Of Surface Defects. Grinding 10Kg/1M2 + Density: 7127M*3.5M = 24,944.50M2, Mowing Grass On The Roadsides In The Amount Of 5000M2. On The Blind Passage: 2961 Potholes Over A Length Of 9307M, I.E. 473.76M2 Of Surface Defects. Grinding 10Kg/1M2 + Density: 9307M*3.5M = 32,574.50M2, Mowing Grass On The Roadsides In The Amount Of 6000M2. For Husband And Wife: 4,220 Potholes Over A Length Of 5,740 M, I.E. 675.20 M2 Of Pavement Losses. Grinding 10 Kg/1 M2 + Density: 5,740 M * 3.5 M = 20,090.00 M2, Mowing Grass On The Roadsides In The Amount Of 4,000 M2.
