Increasing traffic dd2170 and volumes on roads have led to the use of polymer modified binders to improve the performance of bitumen in terms of strength, durability, and resistance to rutting. Go to Wish List.
Current edition approved Oct. Discard any cloudy or unsound portions. The TV has a cover with three openings and lids. Moreover, the results explained that the compatibility between PMMA and asphalt binder is improved upon further aging especially with low molecular weight polymer PMMA. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
This density value is equivalent to a specific gravity of 1. Firm supports for the viscometer shall be provided, or the viscometer may be an integral part of the bath. Why should you use a Tamson Viscosity bath to measure the kinematic viscosity of asphalts bitumens? Indirect tensile strength ITS test and durability performance of modified asphalts were evaluated using Marshall Test.
ASTM D / DM – 10 Standard Test Method for Kinematic Viscosity of Asphalts (Bitumens)
If this efflux time is less than 60 s, select a viscometer of smaller capillary diameter and repeat the operation. Pour sample through tube N to a point just above filling mark G; allow the sample to flow freely through capillary R, taking care that the liquid column remains unbroken, until the lower meniscus is about 5 mm below the filling mark H and then arrest its flow by closing the timing asrm with a cork or rubber stopper in tube L.
Shipment will be made as specified or by best means. D2710 is commonly called the viscosity of the liquid. D — 95 Designation: Box 16, State College, Pa. See Annex A1 for the method of calculation. Since these thermometers are typically in a kinematic viscosity bath which has vision through the frontthe thermometer is read by lowering the thermometer such that the top of the mercury column is 5 to ashm mm below the surface of the bath liquid.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Or visit our webshop to get price and technical information for a viscosity bath and accessories to determine the kinematic viscosity ast asphalts bitumens conform to ASTM D and ISO The practice of completely submerging the thermometer is not recommended. Historical Version s – view previous versions of standard.
This research studies the effect of adding poly methyl methacrylate PMMA with different molecular weights on asphalt properties. The constant ratio of the shearing stress to the astj of shear is the viscosity of the liquid.
Remove the excess sample above filling mark G by inserting the special pipet until its cork rests on top of tube N; apply gentle suction until air is drawn asttm.
ASTM D2170/D2170M – 10
This standard has been approved for use by agencies of the Department of Defense. Results showed that the inclusion of PMMA polymer in asphalt binder has significantly improved its properties.
For the Zeitfuchs Cross-Arm viscometer, apply slight vacuum to tube N or pressure to tube L to cause the meniscus to move over the siphon tube and about 30 mm below the level of tube D in capillary R; gravity flow is thus initiated. The TV and TV have a bath volume of 20 and 40 litres respectively.
Introduce sufficient sample through tube N to completely fill bulb D, overflowing slightly into overflow bulb K.
ASTM D – 01a Standard Test Method for Kinematic Viscosity of Asphalts (Bitumens)
The kinematic viscosity characterizes flow behavior. The values given in column 3 are the limits that should not be exceeded by the difference between the results of two properly conducted tests.
The suggestions in the following sections of this appendix are given specifically for the mercury-in-glass kinematic viscosity thermometers and may not apply to other thermometers. Historical Version s – view previous versions of standard Work Item dd2170 – proposed revisions of this standard Translated Version s: A superscript epsilon e indicates an editorial change since the last revision or reapproval.
The use of similar xstm available sulphuric acid cleaning solutions is acceptable. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. The ice point reading shall be expressed to the nearest 0.
Additional operating instructions for the reverseflow viscometers are outlined in A2. Documents Flashcards V2170 checker. A number in parentheses indicates the year of last reapproval. Add more liquid if necessary to bring the upper meniscus slightly above mark G. B Based on less than 30 degrees of freedom.
