Asphalt pavement material is a precisely engineered product composed of about 95 percent stone, sand, and gravel by weight, and about 5 percent asphalt cement, a petroleum product. Our HMA is mixed at our asphalt … Rubberized Hot Mix Asphalt (RHMA) Mix Design By Jack Van Kirk Director of Asphalt Technology George Reed Inc. CalAPA Fall Conference October 26 - 27, 2016 2. Section 39 Asphalt Concrete 4-3901 General Section 39, “Asphalt Concrete,” of the Standard Specifications provides material and construction requirements for hot mix asphalt (HMA) including Type A, rubberized hot mix asphalt-gap graded (RHMA-G), open-graded friction course (OGFC), minor HMA, and hot mix asphalt with warm mix asphalt (WMA) additive technology. 2.1 This procedure is applicable for all items of hot-mix asphalt pavements requiring compaction testing. P. Romero, Evaluation of non-nuclear gauges to measure density of hot-mix asphalt pavements. Gravity (Gmm) and Density of Hot Mix Asphalt (HMA). scope: This test method covers the determination of the theoretical maximum specific gravity/gravity mix maximum (G mm) and density of uncompacted asphalt mixture at 25 C (77 F).Note 1-The precision of the method is best when the procedure is performed on samples that contain aggregates that are completely coated. Abstract Hot Mix Asphalt Concrete Density, Bulk Specific Gravity, and Permeability Yu Yan Field permeability test using NCAT Permeameter were conducted at four project sites before and after the application of fog seal. Hot mix asphalt mat density data collected during the 1990–1993 implementation of a quality control and quality assurance (QC/QA) program for pavement construction by the Alabama Highway Department (AHD) were analyzed. The following information was testing. Page 3 Rev. This video covers the test for theoretical maximum specific gravity and density of uncompacted hot mix asphalt (HMA) according to AASHTO T 209. ASPHALT WAQTC FOP AASHTO T 209 (12) T209_short_12 Asphalt 15-1 Pub. Hot Mix Asphalt Patching means an HMA surface course placed over localized areas of distressed pavement, generally for the purpose of improving strength, rideability, or safety. October 2012 THEORETICAL MAXIMUM SPECIFIC GRAVITY (Gmm) AND DENSITY OF HOT MIX ASPHALT (HMA) PAVING Hot-mix asphalt (HMA) is a generic term that includes many different types of mixtures of aggregate and asphalt cement (binder) produced at elevated temperatures (generally between 300 Typically, HMA mixtures are divided into three mixture categories: dense-graded; open-graded; and gap-graded as a function of the aggregate gradation used in the mix. A control strip is a short pavement section that is compacted to the desired value under close scrutiny then used as the compaction standard for a particular job. Hot Mix Asphalt AV-8 Optimum binder content for asphalt AV-9 Marshall test AV-10 Binder content / Moisture content AV-11 Static creep test / Immersion index AV-12 Rice’s density and binder absorption/Bulk relative density AASHTO TP4: Preparing and Determining the Density of Hot-Mix Asphalt (HMA) Specimens by Means of the Superpave Gyratory Compactor Performance Tests The original intent of the Superpave mix design method was to subject the various trial mix designs to a battery of performance tests akin to what the Hveem method does with the stabilometer and … Pass Type Density (WD) 1 Vibratory 133.2 pcf 2 Vibratory 136.5 pcf 3 Static 139.7 pcf 4 Static 140.6 pcf 5 Static 136.0 pcf Hot Mix Asphalt Testing Technician Online Homework Page 11 25. Non-destructive assessment of hot mix asphalt compaction/ density with a step-frequency radar: case study on a newly paved road Cyrille Fauchard, Bruno Beaucamp, Laurent Laguerre To … T 312 Preparing and Determining the Density of the Hot-Mix Asphalt (HMA) Specimens by Means of the Superpave Gyratory Compactor 2.2 Asphalt Institute 2.3 ASTM Standards 2.4 WSDOTStandards Construction Manual • The higher the mix temperature the better density could be attained.
