The test facility and the AASHO road test pavement experiments conducted are fully presented and discussed. The behavior and performance of 18 slab and beam bridges under regular test traffic and during accelerated fatigue tests are described. Also reported is an analysis of the fatigue strength of the bridge beams. Field tests and laboratory tests on the fatigue strength of the steel bridges are compared. Tests to failure of the ten test bridges are described. The behavior during the test and under failure of a noncomposite steel bridge, composite steel bridge, reinforced concrete bridge, post-tension prestressed concrete bridge and a pretensioned prestressed concrete bridge is described in detail.

"TRB's National Cooperative Highway Research Program (NCHRP) Report 762: Laboratory Validation of an Endurance Limit for Asphalt Pavements presents models for the hot-mix asphalt fatigue endurance limit that are responsive to asphalt binder and mixture properties and healing between load cycles and are suitable for incorporation as algorithms in Pavement Mechanistic-Empirical Design and other design methods."--Publisher information.

he objective of this study is to examine prevailing rural design standards to determine their economic justification. This would evaluate in depth the cost of some of the most significant design practices (for example, roadway and shoulder width and surfacing type). Resulting user benefits, such as operating, accident and time savings would be weighed against the cost of individual features. In addition to the analysis of the user-benefit relationships, the economic and social consequences to local residents, businesses and communities should be studied and a suitable means of including them in the reckoning of warranted levels of improvement should be found.
