But come Monday morning, it will rumble to life and resume its work paving the southbound lanes of future Interstate 69. The finishing machine is the second of a trio of machines that are used in concrete paving. First is the spreader, which as the name implies, spreads the concrete across the roadway. Next is the finisher, which smooths and levels the concrete to the appropriate depth and angle. Following the spreader and finisher is the tining machine, which draws a wide fork-like device (the tines) horizontally across the roadway, in the process lightly grooving it. All concrete pavement is tined to prevent slipperiness. The tining machine also applies a thin curing-compound membrane to the wet concrete. E. S.
