CC &V PROJECT NO. SC -07 -002 <br />REVISION OF SECTION 401 <br />TEMPERATURE SEGREGATION <br />Section 401 of the Standard Specifications is hereby revised for this project as follows: <br />In subsection 401.16 delete the twelfth (last) paragraph and replace it with the following: <br />February 3, 2011 <br />The Engineer may evaluate the HMA for low density due to temperature segregation any time industry best <br />practices, as detailed on Form 1346, are not being followed or the Engineer suspects temperature segregation is <br />occurring. The Engineer will first meet with the Contractor to discuss the paving practices that are triggering the <br />temperature investigation. Areas across the mat, excluding the outside 1 foot of both edges of the mat, that are <br />more than 25 °F cooler than other material across the width may be marked for density testing. Material for <br />temperature comparison will be evaluated in 3 -foot intervals behind the paver across the width of the mat. The <br />material shall be marked and tested in accordance with CP 58. If four or more areas within a lot of 500 tons have <br />densities of less than 93 percent of the material's maximum specific gravity for SMA mixes or less than 92 percent <br />of the material's maximum specific gravity for all other HMA mixes, a 5 percent price disincentive will be applied to <br />the 500 ton lot. The 500 ton count begins when the Engineer starts looking for cold areas, not when the first cold <br />area is detected. This price disincentive will be in addition to those described in Sections 105 and 106. Only one <br />area per delivered truck will be counted toward the number of low density areas. Temperature segregation <br />checks will be performed only in areas where continuous paving is possible. <br />
