CC &V PROJECT NO. SC -07 -002 <br />Subsection 401.10 shall include the following: <br />Subsection 401.22 shall include the following: <br />Subsection 412.07 shall include the following: <br />1 <br />REVISION OF SECTIONS 401 AND 412 <br />SAFETY EDGE <br />Sections 401 and 412 of the Standard Specifications are hereby revised for this project as follows: <br />The paver shall include an approved longitudinal paver wedge system to create a sloped safety edge as shown <br />on the plans. The wedge system shall be attached to the screed and shall compact the HMA to a density at least <br />as dense as the compaction imparted to the rest of the HMA layer by the paving screed. The system shall <br />provide a sloped Safety Edge equal to 32 degrees plus or minus 5 degrees measured from the pavement surface <br />cross slope extended. The use of a single plate strike off is not permitted. The system shall be adjustable to <br />accommodate varying paving thicknesses. The Engineer may allow the Contractor to use handwork for short <br />sections or to saw cut the sloped Safety Edge after paving operations are completed in areas such as transitions <br />at driveways, intersections, interchanges. <br />The Contractor shall submit the proposed system for approval at the Preconstruction Conference. The <br />Engineer may require proof that the system has been used on previous projects with acceptable results or <br />may require a test section constructed prior to the beginning of work to demonstrate that it creates an <br />acceptable wedge shape and compaction. Paving shall not begin until the system is approved in writing by <br />the Engineer. The Safety Edge may be constructed on each lift of HMA or on the full specified plan depth on <br />the final lift. The finished shape of the Safety Edge shall extend for the full depth of the asphalt pavement or <br />for the top 5 inches whichever is less. <br />All costs associated with the construction of the Safety Edge will not be paid for separately, but shall be <br />included in the work. <br />September 23, 2011 <br />The Contractor shall use an approved longitudinal paver wedge system to create a sloped Safety Edge. The <br />Contractor shall modify the paver screed to create a Safety Edge that meets the final cross - section shown on <br />the plans. The system shall provide a sloped Safety Edge equal to 32 degrees plus or minus 5 degrees <br />measured from the pavement surface cross slope extended. There may be areas where it is not possible to <br />place the Safety Edge in conjunction with mainline paving but where the Safety Edge is required, such as <br />transitions at driveways, intersections, interchanges, etc. In these areas the Engineer may allow the <br />Contractor to use handwork for short sections or to saw cut the sloped Safety Edge after paving operations <br />are completed. <br />The Contractor shall submit the proposed system for approval at the Preconstruction Conference. The <br />Engineer may require proof that the system has been used on previous projects with acceptable results or <br />may require a test section constructed prior to the beginning of work to demonstrate that it creates an <br />acceptable wedge shape. Paving shall not begin until the system is approved in writing by the Engineer. The <br />finished shape of the Safety Edge shall extend for the full depth of the concrete pavement or for the top 5 <br />inches whichever is less. <br />
