5.1 This test method is used to assess in situ strength of undisturbed soil and compacted materials (or both). The penetration rate of the 8 kg [17.6 lb] DCP can be used to estimate in situ CBR (California Bearing Ratio), to identify strata thickness, shear strength of strata, and other material...
5.1 This practice provides a means for obtaining a quantitative estimate of a surface property defined as roughness using longitudinal profile measuring equipment. 5.1.1 The WPRI can be obtained from instruments which can capture high-resolution (described in X1.1.2) longitudinal profiles. 5...
5.1 The parameters KEAC or KIEAC determined by this test method characterize the resistance to crack growth of a material with a sharp crack in specific environments under loading conditions in which the crack-tip plastic region is small compared with the crack depth and the uncracked ligament. The...
1.1 This test method covers Type A Durometer hardness of thermoplastic pavement marking material at elevated temperatures. 1.2 This test method is similar to Test Method D2240 for hardness with special attention given to keeping the temperature of the test sample and instrument constant....
5.1 The pull-off strength and mode of failure of a coating from a concrete substrate are important performance properties that are used in specifications. This test method serves as a means for uniformly preparing and testing coated surfaces, and evaluating and reporting the results. 5.2 Variations...
5.1 For inertial profiler technology, measuring vehicular traveled surfaces using an instrumented vehicle with a fluctuating inertial reference elevation provides a satisfactory method for acquiring profile elevation measurements (1). 5.2 The profile data can be processed to produce, by...
1.1 This practice covers test procedures and conditions that are applicable when Test Methods D5023, D5024, D5026, D5279, and D5418 are used for conducting dynamic mechanical analysis of roofing and waterproofing membrane material in three-point bending, compression, tension, torsion, and dual...
5.1 Acoustical materials are often used as the entire ceiling of rooms and are therefore an important component of the lighting system. The luminous reflectance of all important components must be known in order to predict the level of illumination that will be obtained. 5.2 The reflecting...
1.1 This test method covers the field determination of water penetration of a masonry wall surface under specific water flow rate and air pressure conditions. This test is intended for use on any masonry wall surface that can be properly instrumented and tested within the requirements of...
1.1 This practice describes several field techniques to evaluate the retroreflective properties of pavement markings containing retroreflecting optics (for example, centerlines and edgelines) and applied to the road surface. The techniques described in this practice contain sampling criteria such...
1.1 This test method covers the determination of pile thickness of finished multilevel pile yarn floor covering using a thickness measuring instrument having a stationary surface (platen), a circular pressure foot under specified force, and capable of being moved vertically above the platen....
4.1 These single-number ratings correlate in a general way with subjective impressions of sound transmission for speech, radio, television, and similar sources of noise in offices and buildings. This classification method is not appropriate for sound sources with spectra significantly different...
5.1 The quality of the stripe for visibility in daylight or under road lighting is determined by the luminance coefficient under diffuse illumination, Qd, and depends on the materials used, age, and wear pattern. These conditions shall be observed and noted by the user. 5.2 Under the same...
1.1 This test method covers the field determination of water penetration of a masonry wall surface under specific water flow rate and air pressure conditions. This test is intended for use on any masonry wall surface that can be properly instrumented and tested within the requirements of...
1.1 This test method covers measurement of the retroreflective properties of sign materials such as traffic signs and symbols (vertical surfaces) using a portable retroreflectometer that can be used in the field. The portable retroreflectometer is a hand-held instrument with a defined...
1.1 This test method covers measurement of the retroreflective properties of sign materials such as traffic signs and symbols (vertical surfaces) using a portable retroreflectometer that can be used in the field. The portable retroreflectometer is a hand-held instrument with a defined...
5.1 The quality of the pavement marking is determined by the coefficient of retroreflected luminance, RL, and depends on the materials used, age, wear pattern, application method, pavements surface, and other conditions. 5.2 Under the same conditions of illumination and viewing, larger values of RL...
1.1 This practice covers how to obtain and use data from in-situ measurement of temperatures and heat fluxes on building envelopes to compute thermal resistance. Thermal resistance is defined in Terminology C168 in terms of steady-state conditions only. This practice provides an estimate of that...
1.1 This test method covers procedures for evaluating the pull-off adhesion strength of a coating on concrete. The test determines the greatest perpendicular force (in tension) that a surface area can bear before a plug of material is detached. Failure will occur along the weakest plane within the...
This document describes methods for determining air speed and flow direction, CO, NO and NO2 concentrations and visibility in road tunnels using direct-reading instruments. This document specifically excludes requirements relating to instrument conformance testing.
