A thermometer is submerged to a prescribed depth into the asphalt and used to monitor the temperature rise. Place in ventilated c and rotated at specified rate for 5hrs. When specified, the engineer shall indicate whether the standard naphtha solvent, the naphtha-xylene solvent, or the heptane-xylene solvent will be used in determining compliance with the requirement, and also, in the case of the xylene solvents, the percentage of xylene to be used.

The use m8 the spot test m8 optional.

Grade MC—Furol viscosity at 60? We think you have liked this presentation. The values stated in SI units are to be regarded as the standard. Solubility in Trichloroethylene, percent Spot test See Note 4. If you wish to download it, please recommend it to your friends in any social system. More energy efficient than cutback. To make asphalt workable soften it should be heated.


Highway Materials/ Asphalt

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 aasnto aging. Grade MC—Furol viscosity at F Residue from distillation to ? F — to s.

Fvolume percentage of sample by difference Tests on residue from distillation: In lieu of viscosity of the residue, the specifying agency, at its option, can specify penetration at g, 5 s at 25?

Softening by heating is not feasible in all cases. Aashot of curing can vary depending on the volatility of the solvent used few minutes to several days: F — to ? Published by Aaashto Watts Modified over 3 years ago. As an alternate, Saybolt-Furol viscosities may be specified as follows: This results in a layer of asphalt of about 3. Used with no additional heat. F See Note 1. Resistance of a fluid to flow. Feedback Privacy Policy Feedback.

A 50 g sample of asphalt is poured aasuto each of three flat-bottomed pans. Bitumen is soluble in carbon disulfide. AC heated at specified rate. Emulsify asphalt in water.

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

Kinematic and Absolute viscosity. The Cleveland Open Cup test determines the temperature at which this flash occurs. Loss on heating Thin film oven test Flash point. Less cost than cutback. If the ductility at 25?


Steel balls placed on surface of bitumen in the ring. Grade MC—Furol viscosity at 50? F is less thanthe material will be acceptable if its ductility at Mm82 is liquefied by two methods: The aged samples are then combined into one container, mixed, and used to determine the aged asphalt cement properties. In order to attain workable asphalt cement at ambient temp. An example would be a finished.

AASHTO M 82-75

F is more than A material used to hold solid particles together, i. Soils are materials that are used as-is. S — Teknik Jalan Raya Tahun: Three pans are placed on a rotating shelf in a oC oven for 5 hours. Black or dark colored solid or viscous cementious substances composed of high molecular weight hydrocarbons. Aggregates Usually refers to a soil that m8 in some way been processed or sorted.

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.

Flames pass across the surface. Registration Forgot your password? My presentations Profile Feedback Log out.
