The subject of the order is the renovation of the provincial road number 844 on the Kamen-Volkowiany section from km 11+400 to km 19+410.
Scope of works to be performed:
1) Measurement robots.
2) Demolition works.
3) Paving robots.
4) Mechanically cleaning of the pavement and sprinkling with asphalt emulsion.
5) Surface work.
6) Side of broken aggregate.
7) Restoration of horizontal marking.
Designed robots:
- Surface.
Paving construction
- Making a binding layer of mineral and asphalt mixture AC16W 35/50 KR 3-4 about 5 cm min. 5 cm with alignment of existing pavement diameter 2,5 cm, /total average 7.5 cm/ together with purification and sprinkling,
- Making an abrasive layer from the mineral and asphalt mixture AC11S 50/70 KR 3-4 about 4 cm min.
The width of the new pavement must be performed with the width of the existing pavement.
Restoration of the transverse and longitudinal profile of the road will be obtained together with the planned alignment. No correction is provided in the pavement profile.
Episodes excluded from the scope:
The section from km 16+778 to km 16+842 - new surface on the bridge in Pobołowice.
- The overside.
The slopes perform on a width of 1.0 m and a gr. 0.15 m of stone aggregate broken 0-31.5 mm supplied by the Contractor. Excess allure from the excavations under the roadside trough lay out on earthen roadsides. Where existing vertical marking and traffic safety devices interfere with robots when carrying out the roadsides, they must be dismantled and reinstalled or works near them manually so that the signs and barriers are not damaged.
- Paving robots.
In places where it is necessary to translate paving pavement on entrances, bus bays, pedestrian crossings with adjustment to the height of the new pavement.
On existing bays with asphalt pavement provided for the replacement of curbs with new 20x30x100 cm on a concrete bench with resistance.
- Dehydration.
The dehydration of the w/in the episodes does not change. Transverse and longitudinal drops allow water to runoff into existing roadside ditches and sewable drains.
