Hot mix asphalt is composed of aggregate bound together into a solid mass by asphalt cement. If you have a copy of the delivery ticket, the producer's phone number should be right on there. To get data sheet of bitumen 60/70 and more details on packing and delivery,please visit⇒ bitumen 60/70 Procedures for using the three methods are spelled out on Page 7-17 to 7-21 of the new MS-22 and Page 241 of the old MS-22. The factors are divided into two groups: A and B in Table 1 depending on the density. In different sections of the state it may also be referred to as bituminous concrete,hot plant mix,asphalt concrete, blacktop or Superpave. Joint density is normally most important on high-volume roads and airports. Low temperature prevents aggregate particles from moving, and the required density is not possible to achieve. Density of bitumen is between 1.01 to 1.06 (Kg/dm3) It means that 1.010kg to 1.060kg is one desi cubic meter. First, you have the breakdown roller which develops the majority of the density in an asphalt layer. In addition, following distillation, density is used to assess bitumen quality for classification purposes, and indicates the range of applications different bitumen grades can accommodate. D3665 Practice for Random Sampling of Construction Materials. Thesis submitted to the Benjamin M. Statler College of Engineering and Mineral Resources at West Virginia University in partial fulfillment of the requirements for the degree of . NAPA estimates an average asphalt density of 145 pounds per cubic foot, or 3,915 pounds per cubic yard. 6 (MS-6) shows the factors to be used in calculating the volume of asphalt material at 15oC. The density of bitumen, also called asphalt, is an important indicator of its mass, and is used to determine its commercial value. Yu Yan . For example, if your calculated volume is … Hot Mix Asphalt Concrete Density , Bulk Specific Gravity, and Permeability. density at and around the longitudinal joint. The edge cutter installs on Cat Asphalt Each tons of asphalt needed 70Kg Bitumen and the rest is aggregates. Keep in mind that density is a relative term, compared to a target density of either lab compacted mix, a maximum theoretical density, or a control strip density. Asphalt properties change with temperature, which means that there is a specific range where viscosity permits adequate compaction by providing lubrication between particles during the compaction process. Table 1 from the Asphalt Institute Manual Series No. These are Dense Graded asphalt, Stone Mastic Asphalt and Open Graded Asphalt. The aggregates total Stone mastic asphalt (SMA) is a stone-on-stone like skeletal structure of gap graded aggregate, bonded together by mastic, which actually is higher binder content, filler and fiber to … The process of creating the highest density at the longitudinal joint is the first topic to be addressed. Density of bitumen. Hot mix asphalt may be referred to by several names. The specific gravity test results for asphalt are reported by the refinery or Department chemists. D6752 Test Method for Bulk Specific Gravity and Density of Compacted Asphalt Mixtures Using Automatic Vacuum Sealing Method. User Tip: A useful option for some applications is an edge cutter. D2726 Test Method for Bulk Specific Gravity and Density of Non-Absorptive Compacted Asphalt Mixtures. The asphalt producer (not necessarily the contractor) will have most likely run their own Rice density, on the material you tested, which will give you the exact number you're looking for.
