A FIELD TRIAL OF THE USE OF ROLLER COMPACTED CONCRETE IN HIGH-SPEED TRAFFIC APPLICATIONS . 15TH ARRB CONFERENCE, DARWIN, NORTHERN TERRITORY, 26-31 AUGUST 1990; PROCEEDINGS PARTS 1 TO 7

This paper describes a trial of roller compacted concrete (RCC) pavement in a high-speed traffic application in Melbourne, Australia, specifically the development, assessment and amendment to VIC ROADS specifications for the manufacture of RCC mixes and the construction of RCC pavements. The trial was unique because the use of RCC has been generally confined to low-speed, heavy duty applications because of the perceived difficulties in constructing it to a sufficiently high rideability standard when used as a wearing surface in high-speed applications. The interim materials and construction specifications are described, together with the processes used to develop the job mix and the composition of the test sections. The construction of the pavement is described in detail, together with the results of acceptance testing and other tests conducted on the mix. The results of an evaluation of the characteristics of the pavement surface after construction are briefly summarised. Finally, changes which have been made to the materials and construction specifications as a result of the trial, especially with respect to compressive strength, moisture content and construction techniques, are reported.
