In warm weather rolling on the next day, helps to increase the density if the initial rolling was not adequate. Road Construction Road. The bitumen may be heated up to 150 – 177 deg C and the aggregate temperature should not differ by over 14 deg C from the binder temperature.The hot mixed material is collected from the mixture by the transporters, carried to the location is spread by a mechanical paver at a temperature of 121 to 163 deg C. the camber and the thickness of the layer are accurately verified.The control of the temperatures during the mixing and the compaction are of great significance in the strength of the resulting pavement structure.A mix after it is placed on the base course is thoroughly compacted by rolling at a speed not more than 5km per hour.The initial or break down rolling is done by 8 to 12 tonnes roller and the intermediate rolling is done with a fixed wheel pneumatic roller of 15 to 30 tonnes having a tyre pressure of 7kg per sq.cm.
