The contract includes the renovation of the provincial road No. 838 in the city. Fajsławice on the section from km 24+000 to km 24+730,

Parameters of the road to be renovated:

- road class: Z (collective),

- length of the section – 0.730 km.

Scope of works to be performed:

1) Measurement robots.

2) Demolition works.

3) Milling of bituminous surface.

4) Making a technological band

5) Mechanical cleaning of the surface and sprinkling with asphalt emulsion.

6) Surface works.

7) Shoulders made of broken aggregate.

8) Restoration of road markings.

Existing state:

Surface.

The section to be renovated has a surface in poor technical condition resulting from long-term operation and requires urgent renovation works. On the section in question there are cracks, ruts, transverse and longitudinal irregularities, lack of normative parameters preserved. The existing roadsides are deformed and make it difficult to properly drain rainwater.

Intersection.

Intersections with county roads are located at km 24+213 p. P, 24+457 p. L.

Intersections with municipal roads are located at km 24+213 p. L, 24+457 p. P.

Designed robots.

Surface.

- Execution of a binding layer of asphalt concrete AC16W 35/50 KR 3-4 with a thickness of min. 5 cm with leveling of the existing surface diameter 3 cm, /a total of 8 cm/ with cleaning and sprinkling,

- Execution of an abrasion layer of asphalt concrete AC11S 50/70 KR 3-4 with a thickness of min 4 cm,

Restoration of the transverse and longitudinal profile of the road will be achieved together with the planned alignment. No correction in the pavement profile is foreseen.

Technological band.

- Execution of the foundation from aggregate bound with cement C5/6 gr. 20 cm (lean concrete)

- Execution of the foundation from asphalt concrete AC 16P 35/50 gr. 10 cm,

- Arrangement of glass fiber mesh 120 kN width. 1.0 m (on the joint)

Shoulder.

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.

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.
