"The Standard Specifications for Transportation Materials and Methods of Sampling and Testing, and AASHTO Provisional Standards (the "Materials Standards") contains specifications, recommended practices, and test methods commonly used in the construction of highway facilities. Provisional standards are also published to allow practitioners to use them early in the research or development phase. In addition to revisions to harmonize industry standards, update technology, and generally improve the standards, the 44th edition includes 15 conversions to dual units and more updates to temperature measuring devices. Two of the new standards in this edition include a new test method for determining concrete strength using acoustical resonance methods and a new test method for determining the early opening of concrete pavements using maturity. One of the new provisional standards evaluates the rutting and moisture resistance of paving materials. The 44th edition includes the 8 new and 84 revised standards released in 2024. In total, it contains 564 standards divided into 3 PDF files."--publisher's website
