RATIONALISATION IN CONCRETE ROAD CONSTRUCTION BY SINGLE-LAYER CONSTRUCTION

RATIONALISIERUNG IM BETONSTRASSENBAU DURCH EINLAGIGEN EINBAU

The author attributes the necessity for rationalisation to, among other things, increasing labour costs and the decrease in the standards of workmanship where high quality is required. The introduction of jointless, continuous slabs without mesh reinforcement permits single-layer construction for example. The following advantages are listed: the simplification of material transport, concrete mixing (one mix) and laying: reduced likelihood of disruption to production, avoidance of bonding necessary with two-layer construction. The author sees no difficulties with the vibrating-in of dowel bars or transverse joint inserts. Following this the complete sequence of events of a construction project are described in detail. The details include a description of: the dowel-setting equipment, the leveller, the joint vibrator, the spraying platform. The results of control tests were good: converted cube strengths from the cores, evaluation of the flatness measurements, the thickness of the fine mortar layer, uniform distribution of the additive, voids content. /TRRL/
