Abstract: Scope: This specification pertains to the criteria and tests to be used for determining whether an organic or inorganic processing addition, when used in the recommended amount at the option of the cement producer in the ... -
English -- Standard Method of Test for Flexural Strength of Concrete (Using Simple Beam with Center-Point Loading)
Abstract: Scope: This method covers the determination of the flexural strength of concrete specimens by the use of a simple beam with center-point loading. It is not an alternative to T 97. The values stated in SI units or inch-pound ... -
English -- Standard Practice for Developing Performance Engineered Concrete Pavement Mixtures
Abstract: Scope: This specification covers the tests methods and values for a concrete pavement mixture that considers, and includes, alternative performance characteristics for acceptance. In Section 6 of this specification, SHA ... -
English -- Standard Method of Test for Measuring Interfacial Fracture Energy of Hot-Poured Asphalt Crack Sealant Using a Blister Test
Abstract: Scope: The blister test is used to determine the interfacial fracture energy (IFE) of hot-poured asphalt crack sealant at the application temperature as specified in MP 25 and PP 85. The blister test is a fracture test. ... -
English -- Standard Method of Test for Measuring Adhesion of Hot-Poured Asphalt Crack Sealant Using Direct Adhesion Teste
Abstract: Scope: The direct adhesion test is used to determine the adhesion strength of hot-poured asphalt crack sealant at the application temperature as specified in MP 25 and PP 85. The adhesion test is a test of fracture. The ... -
English -- Standard Practice for Static Segregation of Hardened Self-Consolidating Concrete (SCC) Cylinders
Abstract: Scope: This method covers procedures for determining the static segregation resistance (stability) of selfconsolidating concrete (SCC) using hardened test specimens. The concrete used to make the molded specimens shall be ... -
English -- Standard Method of Test for Detecting the Presence of Phosphorous in Asphalt Binde
Abstract: Scope: This qualitative test method can be used to identify the presence of polyphosphoric acid (PPA) in asphalt binder or residue. If PPA is present in the binder, a blue color is developed in approximately 5 min. The ... -
English -- Standard Specification for Deformed and Plain Carbon and Low-Alloy Steel Bars for Concrete Reinforcement
Abstract: Scope: This specification covers deformed and plain carbon and low-alloy steel concrete reinforcement bars in cut lengths or coils. Steel bars containing alloy additions, such as with the AISI and SAE series of alloy steels, ... -
English -- Standard Method of Test for Frictional Properties of Paved Surfaces Using a Full-Scale Tire
Abstract: Scope: This method covers the measurement of the frictional properties of paved surfaces with a specified full-scale automotive tire. This method utilizes a measurement representing the steady-state friction force on a ... -
English -- Standard Method of Test for Evaluating Stress Development and Cracking Potential due to Restrained Volume Change Using a Dual Ring Test
Abstract: Scope: This test method covers the evaluation of stress development and cracking potential in concrete when volume changes caused by shrinkage and temperature changes are restrained. The procedure is comparative for the ... -
English -- Standard Practice for Grading or Verifying the Sealant Grade (SG) of a Hot-Poured Asphalt Crack Sealant
Abstract: Scope: This standard practice describes the testing required to determine the sealant grade (SG) of a hotpoured asphalt crack sealant according to MP 25, Table 1. It presents two approaches. In the first, the SG of an ... -
English -- Standard Practice for Slurry Seal Design
Abstract: Scope: This standard practice for mix design evaluation uses mixture properties to determine the proportions of emulsified asphalt, mineral aggregate, water, mineral filler, and additives to produce a slurry seal job-mix formula. -
English -- Standard Specification for Steel-Reinforced Polyethylene (PE) Ribbed Pipe, 300- to 1500-mm (12- to 60-in.) Diamete
Abstract: Scope: This specification covers the requirements and methods of tests for steel-reinforced polyethylene (PE) ribbed pipe, couplings, and fittings for use in surface and subsurface drainage applications. Nominal sizes of ... -
English -- Standard Method of Test for Uncompacted Void Content of Fine Aggregate
Abstract: Scope: This method describes the determination of the loose uncompacted void content of a sample of fine aggregate. When measured on any aggregate of a known grading, void content provides an indication of that aggregate’s ... -
