Abstract: GENERAL
Function and Purpose of Signs
support:
This Manual contains Standards, Guidance, and Options for the signing within the right-of way of all types of highways ... -
AASHTO PP 76
Abstract: This method covers the procedure for troubleshooting asphalt specimen volumetric differences between Superpave Gyratory Compactors (SGCs) used in the design and field management of Superpave mixtures. Evaluation of SGCs ... -
AASHTO T 152
Abstract: This method covers determination of the air content of freshly mixed concrete from observation of the change in volume of concrete with a change in pressure.
This method is intended for use with concretes and mortars ... -
AASHTO T 186
Abstract: This test method covers the determination of early stiffening in hydraulic cement paste.
The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. ... -
AASHTO T 190
Abstract: This method covers the procedure for testing both treated and untreated laboratory compacted soils or aggregates with the stabilometer and expansion pressure devices to obtain results indicative of performance when placed ... -
AASHTO PP 60
Abstract: This practice covers the use of a Superpave gyratory compactor (SGC) to prepare 100-mm diameter by 150-mm tall cylindrical test specimens for use in a variety of axial compression and tension performance tests. This practice ... -
AASHTO T 245
Abstract: This method covers the measurement of the resistance to plastic flow of cylindrical specimens of asphalt mixture loaded on the lateral surface by means of the Marshall apparatus. This method is for use with mixtures ... -
AASHTO T 178
Abstract: This test method covers the determination of portland cement content of a sample of hardened hydraulic-cement concrete.
The values in SI units are to be regarded as the standard. The values given in parentheses are ... -
AASHTO HSM
Abstract: PURPOSE AND INTENDED AUDIENCE
The Highway Safety Manual (HSM) provides analytical tools and techniques for quantifying the potential effects on crashes as a result of decisions made in planning, ... -
AASHTO T 133
Abstract: This method covers determination of the density of hydraulic cement. Its particular usefulness is in connection with the design and control of concrete mixtures.
The density of hydraulic cement is defined as the mass ...Subject(s) : Density , hydraulic cement , specific gravity , -
AASHTO R 10
Abstract: This standard practice is to provide standard definitions for terms used in specifications, test methods, and the various quality assurance procedures. -
AASHTO T 152
Abstract: This method covers determination of the air content of freshly mixed concrete from observation of the change in volume of concrete with a change in pressure.
This method is intended for use with concretes and mortars ... -
AASHTO T 90
Abstract: The plastic limit of a soil is the lowest moisture content at which the soil remains plastic. The plasticity index of a soil is the range in moisture content, expressed as a percentage of the mass of the oven-dried soil, ... -
AASHTO LRFR
Abstract: This Manual has been developed to assist Bridge Owners by establishing inspection procedures and evaluation practices that meet the National Bridge Inspection Standards (NBIS). The manual has been divided into nine sections, ...
