EBOMAF-BENIN: Parakou-Wèwè being closed

The city of Parakou will mark its passage in 2017 with a new boulevard of 9,250 km on the axis of Jugou. As part of the project to rehabilitate the Parakou-Wèwè road, the development of this section, like that of the rest of the infrastructure, is inexorably drawing towards its end.

More than two kilometers of bituminous concrete (BB) to reach PK 73 and the coating of PK 2,200 at PK 11,250 to close the Parakou-Wèwè yard. The construction of the three sections of the structure is in its final phase. The overall rate of rehabiliation over 73 kilometres exceeds 90%. Completion is imminent.

The first slice, which ranges from PK 00 to PK 2,200, relates to the strengthening of the existing roadway through the realization of the layers of pavements including the foundation layer and the base layer with a single layer surface coating bond layer and a 5 cm thick SG 014 bituminous concrete bearing layer. As expected in the project, the existing channels were not changed. They were only cured to improve their functionality for water drainage.

The second slice, from PK 2,200 to PK 11,500, 9.250 km long, concerns a double floor two times two tracks with a central floor (TPC). Both carriageways have a width of 9 m each and 2 m for TPC.

So the width of the track is 20 m in total. The work consists of widening the existing road from its initial condition in two times to its reconstructed condition in two times.The surface is currently under way in this area.

This phase takes place as the coronation of the infrastructure since there is only 2 Km of BB to reach the PK 73, said Arouna Mohamed, Director of Works.

The third tranche, from PK 11,500 to PK 73 to Wèwè, 62 km long, is the largest. It is intended to strengthen the existing structure through the construction of the pavements, namely the foundation layer, the base layer and the bonding layer plus the asphalt concrete bearing layer (BB) in semi-green.

Its implementation rate is estimated at 75%. Only 2 Km to be put on on this slice. All the upstream works are also made, reassures Arouna Mohamed.
