AASHTO T 102
Abstract: This method of test is applicable only to asphaltic products derived from petroleum and should not be applied to natural asphalts containing nonbituminous matter insoluble in xylene.
Materials, which by use of standard ... -
AASHTO AAB
Abstract: Introduction
Transportation is about making connections. Transportation agencies connect both people and communities – reaching out across sectors of society and helping to ensure the health of ... -
AASHTO TP 84
Abstract: This test method applies to structures used in AASHTO applications and is applicable to adhesive anchor systems with steel anchors in predrilled holes in concrete.
This test method determines the time to failure for ...Subject(s) : Adhesive anchors , anchors , bonded anchors , concrete , creep test , post-installed anchors , static load test , sustained load test , test methods , time-to-failure test , -
AASHTO T 223
Abstract: This method covers the field vane test in soft, saturated, cohesive soils. Knowledge of the nature of the soil in which each vane test is to be made is necessary for assessment of the applicability and interpretation of ... -
AASHTO T 162
Abstract: This method covers the mechanical mixing of hydraulic cement pastes and mortars of plastic consistency.
The values stated in SI units are to be regarded as the standard.
This standard does not purport to address ... -
AASHTO MP7
Abstract: This specification covers the requirements and methods of tests for corrugated polyethylene (PE) pipe, couplings, and fittings for use in surface and subsurface drainage applications. Nominal sizes of 1350 and 1500 mm are ... -
AASHTO M 307
Abstract: This specification covers silica fume for use in concrete and other systems containing hydraulic cement.
In the cases of slurried or densified silica fume, perform the tests on the raw silica fume from which these ... -
AASHTO PP 61
Abstract: This practice describes testing and analysis for developing a dynamic modulus master curve for asphalt mixtures using the Asphalt Mixture Performance Tester (AMPT). This practice is intended for dense- and gap-graded ... -
AASHTO T 236
Abstract: This method describes procedures for determining the consolidated drained shear strength of a soil material in direct shear. The test may be conducted in either a single shear or in a double shear, as shown in Figure 1. ... -
AASHTO T 272
Abstract: These methods of tests are for the rapid determination of the maximum density and optimum moisture content of a soil sample utilizing a family of curves and a one-point determination.
One-point determinations are made ... -
AASHTO T 196M/T 196
Abstract: This test method covers determination of the air content of freshly mixed concrete containing any type of aggregate, whether it be dense, cellular, or lightweight.
The values stated in either inch-pound or SI units ...Subject(s) : Air content , calibration , concrete , correction factor , freshly mixed concrete , measuring bowl , meter , volumetric method ,
