35. GINE TO COOL Operation THEORY OF OPERATION The RCC130H Crack Saw operates on the principle of transmitting horsepower through a V Belt transmission directly to an industry standard 8 inch diameter diamond segment blade of various widths The crack sawing process is directly controlled by these conditions The use of a suitable mechanism diamond blade of proper design and configuration to penetrate the work surface and remove material while delivering acceptable service life b Sufficient static weight supporting the diamond blade to allow it to effectively penetrate the work surface and remove material Adequate horsepower capable of rotating the diamond blade at industry recognized speeds against the work surface to deliver acceptable productivity rates Since no two materials are exactly alike no two work surface materials can be sawed by the exact same method The nature of the sawing process along with operator experience skill and common sense would suggest that efficient and productive crack sawing is a matter of trial and error Combinations of diamond blade type condition and RCC130H CRACK SAW feed rate are direct factors that will also determine the overall success of the job application INFORMATION RELATIVE TO THE USE OF DIAMOND BLADES Safety requirements always override performance considerations Diamond blade technology has made such rapid advances during the past few years that a d
36. NAL INJURY 10 The wide variety of potential work surface materials along with the corresponding variety of job site environments make it impossible to develop a standardized operating procedure for the Crack Saw Use of the Crack Saw will require constant trial and error testing until satisfactory results are achieved Experience gained over time and common sense will help minimize the amount of necessary testing Many factors will directly affect the operating parameters and or techniques utilized for a specialized job application Some of these factors include a Work surface material yield and tensile values As a general rule these values will determine material removal rate per unit of time Materials with high yield and tensile values will characteristically resist limit material penetration For such materials the accepted procedure is to make a number of multiple passes over the work surface rather than attempt to make a single deep pass The net effect is to actually increase productivity more material removed in less time Other added benefits to this technique are decreased vibration less operator fatigue and increased component service life b The width of the random crack in comparison to the required cutting width and depth For example if the random crack has an average width of 1 8 inch productivity rates will be greater with the use of a 1 4 inch wide blade over that delivered by a 1 2 inch wide blade The same

89. understanding of the difference between crack filling and crack sealing and the working knowledge to understand which one is appropriate for a specific job application is essential for any pavement maintenance contractor An industry accepted definition of crack filling is the placement of materials into cracks to reduce water intrusion and reinforce the adjacent pavement Crack sealing is the placement of specialized materials either above or into working cracks to prevent the intrusion of water and incompressibles such as sand aggregate and dirt Why Do It at Crack sealing is used as a first line of defense against the deterioration of pavement because of its inherent benefits a It protects the base and sub base A good pavement requires a base and sub base of high structural integrity Effective crack gt sealing procedures eliminate water from entering weakening these areas The resulting weakness can result in the loss of structural support which can then further result in the formation of additional cracks and settling around the crack area RCC130H CRACK SAW b It preserves the pavement adjacent to the cracking Cracks that are properly cleaned and sealed contain filler materials that firmly adhere to the crack sides during times of both expansion and contraction Without the addition of these filler materials the adjacent pavement would have increased exposure to the elements resulting in increased oxidat
