| 摘要： | These joints are known as warping joints and can be formed by two different methods: (ⅰ) These can be of construction butt type formed by placing the concrete against the face of the slab cast earlier. The face of the slab cast earlier, shall be painted with bitumen before placing of fresh concrete. (ⅱ) When a pavement of width of more than one lane is laid, the longitudinal joint may be cut by a joint cutting machine. In case of four lane divided road, when a two-lane carriageway (7.25/7.5 m wide) with tied shoulder (2.5 m wide) is laid using full width paver, then, two longitudinal saw cut joints shall be provided- one between the inner and outer lane and the other between outer lane and tied concrete shoulder (Fig. 3). In place of two longitudinal joints, one longitudinal joint may also be provided in the centre of carriageway dividing the carriageway into two equal parts of 4.875/5.0 m width as per the design recommended by the designer (Fig. 4).
