MODIFIED BRIDGE APPROACH PAID road bridge

摘要

The invention relates to the field of road construction, namely, the creation of artificial structures for road toll roads, as well as to the operation of toll roads, bridges and other road structures, such as bridges. Declared modified bridge approach to paid highway bridge comprising a portion embankment subgrade road employee to enter the bridge and exit from it vehicle, characterized in that the bridge approach comprises a secondary portion adjacent to the bridge spans, configured to accommodate the item of charge (PVP), configured as an additional portion of the road embankment subgrade with the roadway, having a longitudinal slope, preferably not more than 5% relative to the horizontal. In this approach, the elongation of the bridge due to the additional portion corresponds to the length of the working zone and PVP is less than or equal to the total length of the bridge highway bridge structures. The technical result of this utility model is to improve road safety when driving vehicles through PVP toll bridge, increased bandwidth PVP, higher throughput toll road (pay road section) starting or ending a bridge structure, by placing PVP raised to secondary portion of the bridge approach embankment and creating conditions to reduce the braking distance of vehicles on staircase PVP to the working area, as well as for the acceleration of vehicles leaving the work area PVP. Another technical effect is to provide a working area PVP minimum length for compact placement PVP infrastructure conditions ensuring traffic safety.
