CC &V PROJECT NO. SC -07 -002 <br />REVISION OF SECTION 401 <br />COMPACTION PAVEMENT TEST SECTION (CTS) <br />Section 401 of the Standard Specifications is hereby revised for this project as follows: <br />In subsection 401.17, delete the fifteenth paragraph and replace with the following: <br />February 3, 2011 <br />Two sets of random cores shall be taken within the last 200 tons of the CTS. Each set shall consist of a minimum <br />of seven random cores. The Engineer will determine the coring locations using a stratified random sampling <br />process. The locations of these cores will be such that one set can serve as a duplicate of the other. One set of <br />these cores shall be immediately submitted to the Engineer. This set will be used for determining acceptance of <br />the CTS and determining density correction factors for nuclear density equipment. Densities of the random <br />samples will be determined by cores according to CP 44. Density correction factors for nuclear density <br />equipment will be determined according to CP 81. Coring shall be performed under CDOT observation. Coring <br />will not be measured and paid for separately but shall be included in the work. For SMA, a CTS is not used. The <br />Contractor shall follow the requirements for the demonstration control strip in accordance with the Revision of <br />Section 403, Stone Matrix Asphalt Pavement. <br />
