Last previous edition D — The kinematic viscosity characterizes flow behavior. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn.

The American Society for Testing and Materials takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. See Annex A1 for the method of calculation. Introduce sample through tube N taking care not to wet the sides of tube N, into the cross-arm D until the leading edge stands within 0.

Be careful to ensure that the expansion chamber at the top of the thermometer is above the lid of the constant temperature bath.

Add to Cart Add to Cart. Add more liquid if necessary to bring the upper meniscus slightly above mark G. Abd ElrhmanSanaa A.

Link to Active This link will always route to the current Active version of the standard. The efficiency of the stirring and the balance between heat losses and heat input must be such that the temperature of the bath medium does not d21770 by more than 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.

Results showed that the inclusion of PMMA polymer in asphalt binder has significantly improved its properties. Originally published as D — 63 T.

ASTM D2170/D2170M – 10

B Based on less than 30 degrees of freedom. Factors controlling heat exchange between the human body and its.

See Annex A1 for the method of calculation. Material and Type Index Single-operator precision: The upper meniscus shall coincide with mark G. Moreover, the results explained that the compatibility between PMMA and asphalt binder is improved upon further aging especially with low molecular weight polymer PMMA.

The kinematic viscosity determined value is the product of the measured flow time and the calibration constant of the viscometer. For the best experience on d210 site, be sure to turn on Javascript in your browser. The kinematic viscosity is then calculated by multiplying the efflux time in seconds by the 1 This test method is under the jurisdiction of ASTM Committee D-4 on Road and Paving Materials and is the direct responsibility of Subcommittee D The values stated in each system may not ashm exact equivalents; therefore, each system shall be used independently of the other.

Determine the efflux time to the nearest 0. Caution should be taken when handling mercury and mercury containing products.

Why is the kinematic viscosity of asphalts bitumens important to know? Work Wstm s – proposed revisions of this standard. The constant ratio of the shearing stress to the rate of shear is the viscosity of the liquid. Nonchromiumcontaining, strongly oxidizing acid cleaning solutions6 may be substituted so as to avoid the disposal problems of chromiumcontaining solutions. The method is used to determine the consistency of bitumen as one element in establishing the uniformity of shipments or sources of supply.

This error can be as much as one or two thermometer divisions. If the test temperature differs from the fill temperature, the viscometer constant is calculated as follows: After allowing the sample to attain bath temperature see A2.

The viscometer bath has a drain to remove the bath content.

Such heating should not exceed 30 min. This density value is equivalent to atsm specific gravity of 1. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

A bath overflow outlet protects from expanding bath oil qstm the bath filling is expanding at higher temperatures. Results of this test method can be used to x2170 viscosity when the density of the test material at the test temperature is known or can be determined.

Increasing traffic loading 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.
