Jointless roadbed of string motorway bridge A design of a jointless roadbed for the string motorway bridge has been developed. It is not affected by thermal deformations. This is achieved by the fact that asphalt is laid on a special slab assembled with rolled steel, which does not change its length along the bridge at temperature drops. This slab rests on a string support structure. Due to this, thermal cracks do not appear in asphalt-concrete of the roadbed. Temperature (deformation) joints are absent over the supports in span structures and, accordingly, in the road-bed. ![]() |
