<br /> <br /> <br />Notes <br />Use the CALTRANS Method. <br />Use the methods of calculation within the applicable test method first. Refer to CTM 105 as <br />necessary. <br />Use the Caltrans Construction Manual procedures as necessary when ASTM D75 or <br />D979 do not adequately cover the item to be sampled. <br />Use the direct transmission method only, the air gap method shall not be used. All <br />nuclear gages must have local Caltrans District calibration within the last year. The data <br />sheets provided by the local Caltrans District shall be used when determining the in- <br />place density. <br />Sample from the job site, across the mat, immediately behind the paving machine (Caltrans <br />Construction Manual). <br />Sample per ASTM D 979 paragraph 4.2.3., sample from the job site, across the mat, <br />immediately behind the paving machine. <br />All nuclear gages used for this test must be calibrated on the six (6) DNTM&R AC Standard <br />Blocks. The Data sheets provided by the local Caltrans District shall be used when <br />determining the in-place density. <br />Recommended Percent (%) AC method for Rubberized Bituminous Paving mixtures. <br />The hand method of shaking is not authorized and shall not be used. An electro- <br />mechanical or hand- operated mechanical. Sand Equivalent shaker must be utilized for <br />this test. <br />This Method covers hot solvent, centrifuge, and vacuum extraction. <br />Compaction Apparatus shall be calibrated in accordance with ASTM D 2168, Method B <br />(ASTM Book 4.08). <br />Test Maximum Density (TMD) shall be performed by Caltrans Test Method 375, Section <br />F. Test Max. Density. <br />Splitters must be of the fixed riffle type (no adjustable splitters). <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />  <br />  <br />City Council 21 – 47 9/16/2025
