Rehabilitation of the TF-335 road
Surface rehabilitation of the road surface of the TF-335 island road, in the section located between P.K. 0+000 and 0+700. Municipal District of Los Realejos.
The rehabilitation work on the TF-335 road involves the restoration of the road surface of a section of road with an initial length of 707 metres, which runs for 100 metres in an urban environment and the remaining 607 metres in an interurban or rural environment.
The rehabilitation project for the TF-335 road envisages the construction of an urban road in the current rural section, with the installation of pavement on the right-hand side and a small hard shoulder on the left-hand side. In this way, the actions are divided according to these two sections: urban and interurban.
The affected lane will be removed in the urban section without soft patches and with deteriorated road surfaces. The base course will be laid with a 5 cm thick base layer of asphalt concrete and a 5 cm thick wearing course.
On the interurban section, the base layer is extended over the existing road surface, and a 7 cm thick base layer of asphalt concrete and a 5 cm thick wearing course of asphalt concrete is laid. On the edges of the carriageway, excavation is carried out to the necessary depth (30 cm below the current asphalt) to spread 30 cm of soil cement, ensuring the primer watering and the previous asphalt layers.
In line with Sando’s commitment to the circular economy and sustainability, up to 30% of all bituminous layers are made from recycled material from the milling and demolition of existing pavement.
Other actions on this section include the demolition of the existing seawall sections and the installation of a metal barrier rail attached to the pavement on the right bank on the sections running from K.P. 0+108 to K.P. 0+487 and on the left bank from K.P. 0+570 to K.P. 0+690. Likewise, all the horizontal signalling affected by the works will be replaced: road markings on the edges and axis of the trunk road and signalling of crossings and intersections, and the placement of the vertical signalling necessary both for the new actions planned and to complement the existing vertical signalling.
