AASHTO R 33
Abstract: This practice covers the calibration of the reference load cell that is used for calibration of a Falling Weight Deflectometer (FWD) in R 32. It is used to establish calibration coefficients for the reference load cell. ...Subject(s) : Calibration , falling weight deflectometer , FWD , load cell , load cell calibration , pavement testing , sensors , -
AASHTO R 18
Abstract: This document contains criteria and guidelines for establishing and implementing a quality management system (QMS) for use by a construction materials laboratory (CML). These criteria may also be used by laboratory-evaluating ...Subject(s) : Calibration , check , construction materials testing , equipment maintenance , internal audit , quality management system , standardization , -
AASHTO T 154
Abstract: This test method covers the determination of the time of setting of hydraulic-cement paste by means of the Gillmore needles.
The values stated in inch-pound units are to be regarded as standard. The values given in ...Subject(s) : Gillmore needles , hydraulic cement paste , time of setting , -
AASHTO M 273M
Abstract: This specification covers single-cell, precast reinforced concrete box sections with less than 0.6 m of cover subjected to highway loadings and intended to be used for the construction of culverts and for the conveyance ... -
AASHTO M 328
Abstract: The objective of this specification is to define the required attributes of an inertial profiler, which, when combined with an operator, becomes a complete inertial profiling system (IPS). The system may be used to measure ... -
AASHTO R 35
Abstract: This standard practice for mix design evaluation uses aggregate and mixture properties to produce a hot mix asphalt (HMA) job-mix formula. The mix design is based on the volumetric properties of the HMA in terms of the air ... -
AASHTO R 9
Abstract: Definition of Acceptance Plan—An agreed upon method of taking samples and making measurements or observations on these samples for the purpose of evaluating the acceptability of a lot of material or construction ...Subject(s) : Acceptance sampling plans , buyer’s risk , control charts , expected pay curve , operating characteristic curve , percent within limits , quality control , seller’s risk , stepped and continuous pay schedules , variability known , variability unknown , -
AASHTO HB-17 DIVISION I SEC 12
Abstract: The specifications of this Section are intended for the structural design of corrugated metal structures. It must be recognized that a buried flexible structure is a composite structure made up of the metal ring and the ... -
AASHTO AU
Abstract: INTRODUCTION: Freeways are highways with full control of access. They are intended to provide for high levels of safety and efficiency in the movement of large volumes of traffic at high speeds. With full control of access, ... -
AASHTO M 155
Abstract: This specification covers material for use under concrete pavement to minimize pumping of the pavement slab.
The values stated in SI units are to be regarded as the standard. -
AASHTO M 20
Abstract: This specification covers the following five penetration grades of asphalt binder for use in highway construction: 40 to 50, 60 to 70, 85 to 100, 120 to 150, and 200 to 300. For asphalt binders graded by viscosity, see ...
