AASHTO PP 83
Abstract: Scope: This standard practice for mix design evaluation uses mixture properties to determine the proportions of polymer-modified emulsified asphalt, mineral aggregate, water, mineral filler, and additives to produce a micro ... -
AASHTO M 140
Abstract: Scope: This specification covers 15 grades of emulsified asphalt for use in pavement construction in the manner designated. Note 1—See M 208 for specifications covering cationic emulsified asphalt and M 316 for ... -
AASHTO T 225
Abstract: Scope: This method covers a procedure for diamond core drilling designed to secure intact samples of rock and some soils that are too hard to sample by soil sampling methods. This method is primarily for obtaining data for ... -
AASHTO R 64
Abstract: Scope: This practice covers field sampling and fabrication and initial curing of 50-mm (2-in.) cube specimens of non-shrink grout or mortar materials, or both. The values stated in either inch-pound or SI units shall be ... -
AASHTO PP 80
Abstract: Scope: This work shall consist of continuous thermal profiling of the asphalt mat temperature immediately behind the trailing edge of the paver screed plate during placement operations. This system includes a display that ... -
AASHTO MP 27
Abstract: Scope: A chip seal is an application of emulsified asphalt, followed immediately by an application of a single layer of cover aggregate. This standard specifies quality requirements for aggregate and emulsified asphalt for ... -
AASHTO PH14
Abstract: Scope: Overview This Handbook provides advice on compliance with the Section 404(b)(1) Guidelines as part of the environmental review process for a transportation project. Section 404(b)(1) Guidelines of the Clean Water ... -

-
AASHTO M 331
Abstract: Scope: Weigh-in-motion (WIM) is the process of measuring the dynamic forces of moving vehicle tires on pavements and estimating the corresponding tire loads of the static vehicle. The dynamic forces of moving vehicles ... -
AASHTO T 355
Abstract: Scope: This test method describes the procedure for determining the in-place density of asphalt mixtures by use of nuclear gauge. The density of the material is determined by the backscatter/air-gap ratio method. ... -
AASHTO T 129
Abstract: Scope: This method covers determination of the normal consistency of hydraulic cement. Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. ... -
AASHTO MASH
Abstract: Scope: PURPOSE AND SCOPE The purpose of this manual is to present uniform guidelines for the crash testing of both permanent and temporary highway safety features and recommended evaluation criteria to assess test results. ... -
