The invention relates to the field of construction, and it can be used in the device bridges across the wide, but shallow watercourses through dry lands, as well as for covering the gaps in subgrade. The object of the utility model is to improve the reliability of the overpass abutment and its bearing capacity. Implementation technical problem is solved by the fact that the abutment trestle comprising plank cell macadam pillow characterized in that it has an array consisting of a plurality gofroobraznyh piles formed by bit-impulse technology (RIE) in okolosvaynom compacted soil, which is laid crushed stone airbag and the abutment of sleeper cells. A useful model to maximize the reliability of the overpass abutment and its bearing capacity at the admission of rolling stock.
