Proposed Standard Test Method for Determining the Dynamic Modulus of Asphalt Mixtures Using the Indirect Tension Test
Abstract: This standard describes the test method for measuring the dynamic modulus of asphalt mixtures using the indirect tension test. This practice is intended for dense- and gap- graded mixtures with nominal maximum aggregate ... -
Standard Practice for Asphalt Tack Coat Design
Abstract: This standard determines an application rate for emulsified asphalt or performance-graded (PG) asphalt binder for tack coats. A tack coat is the application of an emulsified asphalt or performance-graded (PG) asphalt ... -
LRFD Guide Specifications for Accelerated Bridge Construction - Part 1: ABC Design Guide Specifications; Part 2: ABC Construction Guide Specifications - 1st Edition
Abstract: Accelerated Bridge Construction (ABC) technologies have evolved from the laboratory to trial installations into mainstream use. To date, the design and construction of ABC projects has been completed using engineering ... -
Standard Method of Test for Determining the Influence of Road Surfaces on Vehicle Noise Using the Statistical Isolated Pass-By (SIP) Method
Abstract: This test method describes a procedure for measuring the influence of road surfaces on highway traffic noise. The Statistical Isolated Pass-By (SIP) Method provides a quantitative measure of the sound pressure level at ... -
Guide Specifications for Bridges Carrying Light Rail Transit Loads - First Edition
Abstract: These guide specifications (LRT Guide Specifications) are a supplement to the AASHTO LRFD Bridge Design Specifications (LRFD Bridge Design) that address the design of bridges subjected to light rail transit (LRT) loadings, ... -
Standard Specification for Materials for Asphalt Tack Coat
Abstract: This standard specifies quality requirements for emulsified asphalt or performance-graded asphalt binder for tack coats. A tack coat is the application of an emulsified asphalt or performance-graded (PG) asphalt binder, ... -
GUIDE SPECIFICATIONS FOR Analysis and Identification of Fracture Critical Members and System Redundant Members - First Edition
Abstract: The provisions contained herein shall be used to evaluate system-level redundancy of a bridge after the failure of a member traditionally designated as an FCM. The results of the evaluation shall place such members into ... -
Guide Specifications for the Design of Concrete Bridge Beams Prestressed with Carbon Fiber-Reinforced Polymer (CFRP) Systems - First Edition
Abstract: These guide specifications apply to the design of prestressed concrete beams constructed of normal weight concrete and prestressed by carbon fiberreinforced polymer (CFRP) prestressing systems. Unless otherwise specifically ... -
Guide Specifications for Internal Redundancy of Mechanically-Fastened Built-Up Steel Members - AASHTO
Abstract: GENERAL These provisions shall be used for the evaluation of internal redundancy in built-up members traditionally designated as Fracture Critical Members (FCM). These provisions shall be used during the design of new ... -
Standard Method of Test for Determining the Cracking Temperature of Asphalt Binder Using the Asphalt Binder Cracking Device (ABCD)
Abstract: This test method covers the determination of cracking temperatures of asphalt binders by the means of an Asphalt Binder Cracking Device (ABCD). This device can be used with unaged material or with material aged using T ... -
Roadway Lighting Design Guide - 7th Edition
Abstract: OVERVIEW This is the seventh edition of the AASHTO Roadway Lighting Design Guide, with the sixth edition having been published in October 2005. This seventh edition has been revised to reflect current practices in roadway ... -
A Policy on Geometric Design of Highways and Streets - Seventh Edition; Incorporating Errata: October 2019
Abstract: Public works projects of all scales are more sensitive to funding than ever before. In many cases, cost magnitude and cost effectiveness play increasingly large roles in scoping projects. Often, reconstruction projects ... -
