AASHTO MP 12
Abstract: Detectable warnings provide a distinctive surface of truncated domes detectable by cane or underfoot to alert people with vision impairments of the transition to vehicular ways. These warnings compensate for the sloped ... -
AASHTO TP 76
Abstract: This test method describes the procedures for measuring tire/pavement noise using the on-board sound intensity (OBSI) method and the procedures for verification of the measurement system. The test method provides an objective ... -
AASHTO T 196M/T 196
Abstract: This test method covers determination of the air content of freshly mixed concrete containing any type of aggregate, whether it be dense, cellular, or lightweight.
The values stated in either inch-pound or SI units ... -
AASHTO T 215
Abstract: This method describes a procedure for the determination of the permeability of water through granular (cohesionless) soils in a steady-state condition.
The determination of the coefficient of permeability, k, as defined ... -
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 R 60
Abstract: This method covers the procedures for obtaining representative samples of fresh concrete as delivered to the project site and on which tests are to be performed to determine compliance with quality requirements of the ... -
AASHTO T 347
Abstract: This test method covers determination of slump flow of self-consolidating concrete (SCC), both in the laboratory and in the field. SCC is defined as a highly workable concrete that can flow through densely reinforced or ... -
AASHTO T 100
Abstract: This method covers determination of the specific gravity of soils composed of particles smaller than the 4.75-mm (No. 4) sieve by means of a pycnometer. When the soil is composed of particles larger than the 4.75-mm (No. ... -
AASHTO FGCP-1
Abstract: Scope and Objective
Construction sites can be a source of sediment and other pollutants to waterways. Best management practices (BMPs) are devices and activities that reduce or eliminate pollution ... -
AASHTO T 209
Abstract: This test method covers the determination of the theoretical maximum specific gravity/gravity mix maximum (Gmm) and density of uncompacted hot mix asphalt (HMA) at 25°C (77°F).
