AASHTO T 140
Abstract: This method covers the determination of compressive strength of concrete, using portions of beams broken in flexure for test specimens.
Note 1—This method was originally developed to cover testing ... -
AASHTO TP 96
Abstract: This method covers test methods and selection criteria for prequalification of sealers for protecting new concrete or prolonging the life of sound in-service concrete used in highway structures. Sealer testing and evaluation ... -
AASHTO HDG CHAPTER 14
Abstract: INTRODUCTION
Drainage facilities, like all other elements of the highway system, deteriorate and decay due to the persistent forces of nature. Processes such as abrasion, corrosion, and erosion can ... -
AASHTO M 230
Abstract: This specification covers expanded and extruded polystyrene board used for lightweight fill or highway pavement insulation applications. -
AASHTO R 49
Abstract: This standard practice covers the determination of low-temperature properties of asphalt binders using data from the bending beam rheometer (T 313) and the direct tension tester (T 314). This standard practice can be used ... -
AASHTO T 273
Abstract: This method covers the procedure for determining total soil suction force using thermocouple psychrometers. The test results of this method are to be used in conjunction with T 258.
The thermocouple psychrometer ... -
AASHTO GHOV-3
Abstract: Introduction
Limited right-of-way and economic realities often dictate that public investments be concentrated toward increasing the efficiency of and preserving the existing transportation infrastructure ... -
AASHTO T 146
Abstract: These methods of test cover the wet preparation of soil samples as received from the field, for mechanical analysis, and the determination of soil constants.
Method A provides for drying the field samples at a temperature ... -
AASHTO M 57
Abstract: This specification covers materials for use in the construction of embankments and subgrades.
The values stated in SI units are to be regarded as the standard. -
AASHTO M 316
Abstract: This specification covers grades of polymer-modified cationic emulsified asphalt for use in pavement construction. The modifier may be either a solid or a latex polymer. The modifier may be added either to the asphalt ... -
AASHTO M 54M/M 54
Abstract: This specification covers material in mat (or sheet) form fabricated from deformed steel bars to be used for the reinforcement of concrete. Mats consist of two layers of bars that are assembled at right angles to each ... -
AASHTO GTDP
Abstract: Introduction
Objective
The objective of the guidelines is to improve the quality of the traffic information that supports decisions at all levels of the transportation profession. ... -
AASHTO M 291
Abstract: This specification2 covers chemical and mechanical requirements for eight grades of carbon and alloy steel nuts for general structural and mechanical uses on bolts, studs, and other externally threaded parts. ...Subject(s) : alloy steel , carbon steel , nuts , steel , weathering steel , -
AASHTO T 136
Abstract: These methods cover procedures for determining the soil-cement losses, moisture changes, and volume changes (swell and shrinkage) produced by the repeated freezing and thawing of hardened soil-cement specimens. The specimens ... -
AASHTO T 170
Abstract: This method covers the recovery, by the Abson Method, of asphalt binder from a previously conducted extraction with reagent-grade trichloroethylene or reagent-grade methylene chloride (Note 1). The asphalt binder is recovered ...
