Details are given of the first trial length of continuously reinforced concrete overlay constructed in Great Britain on a stretch of the A3 trunk road near the Hampshire town of horndean. The trial section, 1600 M long, was split into two. Half the length was given a 130 mm thick overlay and a 110 mm thick layer was put on the other half. Content of deformed reinforcement fabric was 0,6 and 0,7 per cent respectively. Concrete for the overlay had a maximum 20 mm aggregate. A compaction factor of 0,88 plus or minus 0,03 was specified equivalent to approximately 25 mm slump. A Gunter and Zimmerman slip former was used. The 1600 M of 9 M carriageway was laid in six days. The maximum length laid in one day was 400 M. Concrete cylinders were taken to test the concrete's tensile strength. (TRRL)
