Of ASTM D (Medium-Curing Asphalt) or AASHTO M Intended Uses: Major use for MAFCO Cutback MC is in the road maintenance industry where it is. Standard Specification forCutback Asphalt (Medium-Curing Type) AASHTO Designation: M () 1. SCOPE 1. In previous editions, AASHTO has printed ASTM standards which have been adopted by A complete list of AASHTO specifications with corresponding ASTM .

Consistency can be further modified by air blowing. Emulsions are graded based on the rate of setting: M 1. F —60 to s.

Ring suspended in water bath. Grade MC—Furol viscosity at 60? AC heated at specified rate.

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

The emulsion stay in this stable situation until disturbed by: F — m28 ? Aasyto like electrical charges repel, asphalt droplets stay suspended in water. Flames pass across the surface.

SCOPE This specification covers liquid petroleum products, produced by fluxing an asphaltic base with suitable petroleum distillates, to be used in the treatment of road surfaces. Three pans are placed on a rotating shelf in a oC oven for 5 hours. About project SlidePlayer Terms of Service.


Steel balls placed on surface of bitumen in the ring. When the temperature gets close to the suspected flash point, the gas line is turned on and a small flame lit at the end of the wand. The aged samples are then combined into one container, mixed, aashgo used to determine the aged asphalt cement properties.

F — to s. Resistance of a fluid to flow. F See Note 2.

AASHTO M 82-75

To make this website work, we log user data and share it with processors. Auth with social network: Kinematic and Absolute viscosity.

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. F Residue from distillation to ? To make asphalt workable soften it should be heated. Air blowing is used to increase viscosity of asphalt residue. In lieu of viscosity of the residue, the specifying agency, at its option, can specify penetration at g, 5 s at 25?

Grade MC—Furol viscosity at 50? We think you have liked this presentation. Rotating Shelf Outside of Oven. Evaporation breaks the anionic Electromechanical process breaks the cationic. Consistency can be controlled by the mount of heavy gas oil removed. Used to separate volatile from nonvolatile substances. However, in no case will both be required.


Absolute viscosity at 60? Emulsifying agents place electrical aashot around each droplet of asphalt. An example would be a finished. Softening by heating is not feasible in all cases. 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. The values stated in SI units are to be regarded as the standard. Loss on heating Thin film oven test Flash point.

Bitumen is soluble 8m2 carbon disulfide. F is less thanthe material will be acceptable if its ductility at My presentations Profile Feedback Log out.

Asphalt is liquefied by two methods: S — Teknik Jalan Raya Tahun: Registration Forgot your password? Place in ventilated c and rotated at specified rate for 5hrs. If you wish to download it, please recommend it to your friends in any social system. More energy efficient than cutback. Grade MC—Furol viscosity at The use of the spot test is optional.
