Emulsify asphalt in water. Consistency can be controlled by the mount of heavy gas oil removed. Place in ventilated c and rotated at specified rate for 5hrs. Asphalt is liquefied by two methods: Grade MC—Furol k82 at aaahto F — to s. Aggregates Usually refers to a soil that has in some way been processed or sorted. Rotating Shelf Outside of Oven. This test can also be used to measure the loss of volatiles in the asphalt cement by determining the percent difference in the mass before and after aging.

If you wish to download it, please recommend it to your friends in any social system. To make asphalt workable soften it m822 be heated. Air blowing is used to increase viscosity of asphalt residue. In order to attain workable asphalt cement at ambient temp.

AASHTO M 82-75

F See Note 1. In lieu of viscosity of the residue, the specifying agency, at its option, can specify penetration at g, 5 s at 25? The values stated in SI units are to be regarded as the standard.


Kinematic and Absolute viscosity. An example would be a finished. Soils are materials that are used as-is. Bitumen is soluble in carbon disulfide. Emulsions are aasuto based on the rate of setting: Kinematic Viscosity 60C cSt asphalt air Grades based on min.

Three pans are placed on a rotating shelf in a oC oven for 5 hours. Distillation used in Cutback asphalt Loss on heating: To make this website work, we log user data and share it with processors. Since like electrical charges repel, asphalt droplets stay suspended in water. Grade MC—Furol viscosity at 50?

Neoprene 55 Duro – AASHTO M Grade 3 – 1/4″ Thick x ” x 4″ – M82

F Residue from distillation to ? Used with no additional heat. Auth with social network: The emulsion stay in this stable situation until disturbed by: My presentations Profile Feedback Log out. Evaporation breaks the anionic Electromechanical process breaks the cationic.

The flash point is the temperature at which a small blue flicker around the inside of the cup is seen as the wand is passed horizontally over the surface of the cup. Dissolve Cut the asphalt in solvent. The aged samples are then aashtl into one container, mixed, and used to determine the aged asphalt cement properties. More energy efficient than cutback.


Grade MC—Furol viscosity at F —60 to s.

Published by Giles Watts Modified over 3 years ago. Solubility in Trichloroethylene, percent Spot test See Note 4. Softening by heating is not feasible in all cases.

As an alternate, Saybolt-Furol viscosities may be specified as follows: Distance in centimeters to which a standard sample may elongate without breaking. This results in a layer of asphalt of about 3. M 1. SCOPE Ashto specification covers m28 petroleum products, produced by fluxing an asphaltic base with suitable petroleum distillates, to be used in the treatment of road surfaces.

Registration Forgot your password? Rate of curing can vary depending on the volatility of the solvent used few minutes to several days: Fvolume percentage of sample by difference Tests on residue from distillation: Standard naphtha Naphtha-xylene solvent, percent xylene Heptane-xylene solvent, percent xylene 30 38 aasht 60 — 0. The Cleveland Open Cup test determines the temperature at which this flash occurs. We think you have liked this presentation.

A thermometer is submerged to a prescribed depth into the asphalt and used to monitor the temperature rise. F See Note 2. F is more than Ring suspended in water bath.
