Design and Control of Bituminous Mixtures Using a Modified Marshall Design Procedure 1. General Scope ... increases in asphalt in mixes which contain a large amount of filler. ... Determine Specific Gravity of Asphalt @ 25 oC (77F) (Specific Gravity @ 16 oC (60F) - 0.007). (AASHTO T228).

60/70. This asphalt material, supplied by El-Suez is the usual asphalt grade used for asphalt pavement construction in Egypt. The specific gravity of asphalt cement used was 1.035. The coarse aggregate, fine aggregate, mineral filler and asphalt cement were used to prepare the Marshal test specimens with 65 mm height and 101.6 mm diameter.

For more specific details on testing for theoretical maximum or asphalt specific gravity and density, refer directly to the ASTM D2041 or AASHTO T 209 test standards. You can also learn more about the SGA-5R Rice Shaker for Specific Gravity & Asphalt Rice Test by viewing our video on YouTube.

The bulk specific gravity of the mineral filler is difficult to determine accurately. Therefore, use the apparent specific gravity for filler. The apparent specific gravity of mineral filler is determined in accordance with CT 208. Report results to the nearest 0.001. Page 2/5

ALDOT-384-95 SUPERPAVE MIX DESIGN PROCEDURE FOR ASPHALT MIXTURES 1. Scope ... T 84 Specific Gravity and Absorption of Fine Aggregate ... The apparent specific gravity of mineral filler shall be used in lieu of the bulk specific gravity in the above equation.

and it was demonstrated that different fillers affect the properties of asphalt paving mixtures differently. It was si^gested that such changes in test properties can be associated with changes in viscosity of the filler-asphalt binder containing different fillers. However, direct correlation between filler-asphalt binder viscosity and compacted

1002.4 Qualified Mineral Filler for Stone Matrix Asphalt (SMA) ... Fine aggregate submitted for Superpave (Trial Mix) shall be tested by AASHTO T84 for bulk specific gravity. Mineral filler and hydrated lime shall be tested in accordance with MoDOT Test Method T37.

CHAPTER 7 TESTING OF ASPHALT CONCRETE MIXTURES Asphalt Testing ... Asphalt Content, Voids in Total Mix (VTM), Voids Filled with Asphalt (VFA), Voids in ... the complement of the percent density when based upon the maximum specific gravity (G mm). The VTM obtained in the Superpave Mix Design gives an indication of whether the

The use of hydrated lime or kaolin as a filler requires more asphalt because of their relatively higher specific surface area. The highest stiffness performance was found for W3B-hydrated lime, followed by W3B-granite, and W3B-kaolin mixtures.

Custom manufacturer of asphalt & concrete joint sealants. Specifications of asphalt & concrete joint sealants include 0.96, 1.07 & 1.13 specific gravity, 1,300 cps, 1,600 cps & 2,000 cps viscosity, 35 shore A at 75 degrees F hardness, 0.51 percent at 75 degrees F water absorption & 520 V/mil. dielectric strength.

material. Obtain the specific gravity of the extracted asphalt and calculate the specific gravity of the combined aggregate in the reclaimed material. 2.2. Determine the specific gravity of the asphalt cement. 2.3. Calculate the Bulk Specific Gravity of the aggregate combination in the paving mixture. (G sb) 2.4.

ND T 209 - THEORETICAL MAXIMUM SPECIFIC GRAVITY AND DENSITY OF HOT MIX ASPHALT . Conduct this procedure according to ND T 209. The AASHTO standard test procedure specifies flasks are agitated for 15 ± 2 minutes and, after agitation, the flasks are immersed in water for 10 ± 1 minutes.

DESIGN OF BITUMINOUS MIXTURES TxDOT Designation: Tex-204-F Effective Date: August 2016 1. SCOPE 1.1 Use the methods in this procedure to determine the proper proportions of approved aggregates, mineral filler, asphalt binder, additives, and recycled materials that, when ... Specific gravity of the asphalt binder determined at 77°F (25°C) ...

Effective Specific Gravity, G se. Volume measurement includes the volume of the aggregate particle plus the void volume that becomes filled with water during the test soak period minus the volume of the voids that absorb asphalt. Effective specific gravity lies between apparent and bulk specific gravity.

Specific Gravity - the specific gravity of an aggregate is needed in order to properly design and proportion an asphalt mix. Absorption - the absorption of an aggregate refers to the amount of void spaces within a particle that may be filled with asphalt binder (or air or water), and is a measure of the tendency of an aggregate to absorb ...

The theoretical maximum specific gravity (Gmm) of a HMA mixture is the specific gravity excluding air voids. Thus, theoretically, if all the air voids were eliminated from an HMA sample, the combined specific gravity of the remaining aggregate and asphalt binder would be the theoretical maximum specific gravity. Theoretical maximum specific ...

Keywords: Asphalt concrete, Filler, Lime stone, Portland cement, Hydrated lime, Durability. 1. Introduction 1Asphalt concrete (sometimes referred to as "ot ix Asphalt" or simply "A") is a paving material that consists of asphalt binder, aggregate and mineral filler. The asphalt binder, which can be asphalt cement or

The approach to this review had been to separately examine three specific gravity determinations, namely, the bulk specific gravity of the aggregate (G. sb), the maximum specific gravity of asphalt mixtures (G. mm), and the bulk specific gravity of compacted specimens (G. ). The review draws upon
