HOT-MIX ASPHALT -DENSITY TESTING OF LONGITUDINAL JOINTS (BDE) <br /> Effective: January 1, 2010 <br /> �i Revised: April 1, 2016 <br /> +� Description. This work shall consist of testing the density of longitudinal joints as part of the <br /> quality control/quality assurance (QC/QA) of hot-mix asphalt(HMA). Work shall be according to <br /> 1 Section 1030 of the Standard Specifications except as follows. <br /> Quality Control/Quality Assurance (QC/QA). Delete the second and third sentence of the third <br /> paragraph of Article 1030.05(d)(3) of the Standard Specifications. <br /> Add the following paragraphs to the end of Article 1030.05(d)(3) of the Standard Specifications: <br /> "Longitudinal joint density testing shall be performed at each random density test <br /> location. Longitudinal joint testing shall be located at a distance equal to the lift <br /> thickness or a minimum of 4 in. (100 mm), from each pavement edge. (i.e. for a 5 in. <br /> (125 mm) lift the near edge of the density gauge or core barrel shall be within 5 in. <br /> (125 mm) from the edge of pavement.) Longitudinal joint density testing shall be <br /> performed using either a correlated nuclear gauge or cores. <br /> a. Confined Edge. Each confined edge density shall be represented by a one- <br /> minute nuclear density reading or a core density and shall be included in the <br /> average of density readings or core densities taken across the mat which <br /> represents the Individual Test. <br /> b. Unconfined Edge. Each unconfined edge joint density shall be represented by <br /> an average of three one-minute density readings or a single core density at the <br /> given density test location and shall meet the density requirements specified <br /> herein. The three one-minute readings shall be spaced 10 ft (3 m) apart <br /> longitudinally along the unconfined pavement edge and centered at the random <br /> density test location." <br /> Revise the Density Control Limits table in Article 1030.05(d)(4) of the Standard Specifications to <br /> read: <br /> "Mixture Parameter Individual Test Unconfined Edge <br /> 9 <br /> Composition (includes confined Joint Density <br /> edges) Minimum <br /> IL-4.75 Ndesi n = 50 93.0—97.4%-T 91.0% <br /> IL-9.5 Ndesi n = 90 92.0-96.0% 90.0% <br /> IL-9.5,IL-9.5L Ndesi n < 90 92.5-97.4% 90.0% <br /> IL-19.0 Ndesi n = 90 93.0-96.0% 90.0% <br /> IL-19.0, IL-19.OL Ndesi n < 90 93.0 —97.4% 90.0% <br /> SMA Ndesi n = 50 &80 93.5-97.4% 91.0%" <br /> 80246 <br />
