These include a Purpose of Vibration but are not limited to mix design paver speed The use of internal vibration 1 required to improve the workability of low slump con crete used in slip form paving Low slump concrete reduces edge slump conditions which allows the concept of slip form paving to work Also lower slump concrete general d ly means a lower water to cement ratio which increases pavement strength Vibration increases the workability of concrete by flu idizing it and helps to provide a smooth work able surface Equally important it consoli dates the concrete reducing entrapped air honey combing cold jointing and other inter nal flaws which would reduce pavement strength e b Vibrator Positioning and Spacing c Proper positioning and operation of vibrators in the paving slip form molds is important to provide proper consolidation of the concrete Generally the distance between vibrators should be between 12 and 24 inches depend ing on mix design paver speed vibrator speed and numerous other factors The proper position of the vibrators should be with their tips angled downward slightly and as close to the center of the slab as possible With the vibrator tip angled down into the center of the slab the opening created by the vibrator will have a tendency to fill with a more uniform mixture Also the highly vibrated concrete directly next to the vibrator will be spread over a larger area reducin
