MODIFIED BY BRIDGE APPROACH OF PAID HIGHWAY BRIDGE CONSTRUCTION C BY THE INCREASED ADDITIVE ZONE

摘要

The invention relates to the field of road construction, namely, the creation of artificial toll road constructions, in particular, road overpasses, bridges and overpasses. Declared modified bridge approach to toll road bridges comprising land embankment subgrade road which serves for entry into the underpass and exit from it vehicle, as well as for the item of charge (PVP), which is arranged on the elongated secondary portion embankment subgrade road , taken with the broadening of the carriageway. Said secondary portion joins the roadway of a bridge construction with the main portion of the roadway of the bridge approach, the profile of the carriageway on the additional portion is formed with a longitudinal bias of not more than 5% with respect to the horizontal. An elongate mound additional modified bridge approach portion has a length L2 that is greater than the length L1 of the working area PVP: L2 L1. Technical result of utility model is to improve road safety at the entrance to the PVP pay bridge structures and increase the capacity of the PVP by creating favorable conditions for the "start-stop" movement of vehicles waiting to enter the working PVP zone from modified bridge approach and reduced wear of the top of the road pavement.
