Soils are materials that are used as-is. 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.

Distillation used in Cutback asphalt Loss on heating: Published by Giles Watts Modified over 3 years ago.

AASHTO M 82-75

About project SlidePlayer Terms of Service. AC heated at specified rate. F See Note 2. To make asphalt workable soften it should be heated. Since like electrical charges repel, asphalt droplets stay suspended in water.

In order to attain workable asphalt cement at ambient temp. Emulsify asphalt in water. M 1. F —60 to s.

Highway Materials/ Asphalt

F is more than 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.


Fvolume percentage of sample by difference Tests on residue from distillation: F is less thanthe material will be acceptable if its ductility at Bitumen is soluble in carbon disulfide. Share buttons are a little bit lower. Used with no additional heat. Distillation, percentage by volume of total distillate to ?

Distance in centimeters to which a standard sample may elongate without breaking. Feedback Privacy Policy Feedback. Grade MC—Furol viscosity at 50?

Three pans are placed on a rotating shelf in a oC oven for 5 hours.

F — to s. Ring suspended in water bath. 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. Dissolve Cut the asphalt in solvent. If the ductility at 25? Penetration is found for aged samples.

In this test, a small sample n82 asphalt is poured into the brass cup which is placed over an electric heater. An example would be a finished. The emulsion stay in this stable situation until disturbed by: Flames pass across the surface. Steel balls placed on surface of bitumen in the ring. The use of the spot test is optional. Standard naphtha Naphtha-xylene solvent, percent xylene Heptane-xylene solvent, percent xylene 30 38 — 60 — 0.

Auth with social network: Used to separate volatile from nonvolatile substances. Grade MC—Furol viscosity at To make this website work, we log user data and share it with processors.

Air blowing is used to increase m882 of asphalt residue. S — Teknik Jalan Raya Tahun: 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. Consistency can be further modified by air blowing. Emulsifying agents place electrical charge around each droplet of asphalt.
