Abstract: Except for cover plated beams, the evaluation procedures apply to uncracked steel members subjected to primary stresses. The procedures do not apply to members that have sustained severe corrosion or mechanical damage or that have been repaired after sustaining fatigue cracking. NCHRP Report 299 gives information and references on the fatigue behav...

Abstract: This Guide for Pavement Friction was prepared under NCHRP Project 1-43 to provide highway pavement practitioners with guidance in designing, constructing, and managing pavement surfaces—as part of both new and ...

Abstract: This practice covers the accelerated aging (oxidation) of asphalt binders by means of pressurized air and elevated temperature. The test method is intended to simulate in-service oxidative aging of asphalt binders and is intended for use with residue from T240 (RTFOT).
The aging of asphalt binders during service is affected by mixture-associate...

Abstract: These methods cover the reduction of large samples of aggregate to the appropriate size for testing, employing techniques that are intended to minimize variations in measured characteristics between the test samples so selected and the large sample. 
The values stated in SI units are to be regarded as the standard. 
This standard ...

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 ...

Abstract: These definitions cover terms used in descriptions and specifications of materials occurring as or employed in the construction of subgrades, soil-aggregate base and surface courses, and fills.
The values stated in SI ...

Abstract: This test method covers the determination of the fineness of hydraulic cement by means of the 45-μm (No. 325) sieve.
The values stated in SI units are to be regarded as the standard. The inch–pound equivalents of SI units may be approximate.
This standard does not purport to address all of the safety concerns, if any, associated ...
