AASHTO HDG CHAPTER 13
Abstract: INTRODUCTION: Highway drainage is an important aspect of any highway design. The level of involvement of design personnel in the field of drainage design ranges from occasional contact with the subject to those who specialize ... -
AASHTO T 300
Abstract: The force ductility of an asphalt material is determined by measuring the tensile stress induced on a specimen when two ends of a briquet specimen of the material are pulled apart at 5 cm/min (2 in./min) and at a specified ...Subject(s) : Asphalt , ductility , force ductility , force ratio , -
AASHTO HM-32 PT II
Abstract: INTRODUCTION
This Thirty-Second Edition of Transportation Materials is published in two parts. Part 1 contains specifications for materials, and Part 2 includes methods of testing and specifications ... -
AASHTO M 145
Abstract: This recommended practice describes a procedure for classifying soils into seven groups based on laboratory determination of particle size distribution, liquid limit, and plasticity index. Evaluation of soils within each ... -
AASHTO M 156
Abstract: This specification covers requirements for plants producing hot mix asphalt (HMA) or warm mix asphalt (WMA) paving mixtures. It may be used as a basis for state certification or inclusion of an asphalt mixing plant on an ... -
AASHTO T 100
Abstract: This method covers determination of the specific gravity of soils by means of a pycnometer. When the soil is composed of particles larger than the 4.75-mm (No. 4) sieve, the method outlined in T 85 shall be followed. When ... -
AASHTO DIVISION I 4.2
Abstract: GENERAL: Foundations shall be designed to support all live and dead loads, and earth and water pressure loadings in accordance with the general principles specified in this section. The design shall be made either with ... -

Abstract: This specification covers welded wire reinforcement to be used for the reinforcement of concrete.
Note 1—Welded wire for concrete reinforcement has been described by various terms: welded ...Subject(s) : Concrete reinforcement , reinforced concrete , reinforcing steels , steel wire , welded wire reinforcement , -
AASHTO R 8
Abstract: This standard practice is to provide guidance for the assessment of potential or alleged structural damage due to earthborne vibrations related to transportation facility construction, maintenance, or operation. -
AASHTO PP 78
Abstract: This recommended practice provides guidance for designing asphalt mixtures that incorporates reclaimed asphalt shingles (RAS) from manufactured waste or tear-off sources. Specific guidance includes design considerations, ... -
AASHTO R 56
Abstract: This practice describes a certification procedure for test equipment used to measure a longitudinal surface elevation profile of highways based on an inertial reference system that is mounted on a host vehicle. The minimum ...Subject(s) : Inertial profiler , International Roughness Index , IRI , pavement ride quality , profiler certification ,
