- The AASHO road test : proceedings of a conference held May 16-18, 1962, St. Louis, Mo. by Highway Research Board Conference on the AASHO Road Test(1962 :Saint Louis, Mo.); National Research Council (U.S.).Highway Research Board.(CARDINAL)141288; American Association of State Highway Officials.(CARDINAL)138447;
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.Includes bibliographical references.Opening remarks -- History of project -- The road test bridges: History and objectives -- Behavior of AASHO road test bridge structures under repeated overstress -- Tests to failure with increasing loads of the AASHO test bridges -- Dynamic studies of the AASHO road test bridges -- Summary report on bridge research -- Special deflection studies on flexible pavement -- Slope variance as a measure of roughness and the CHLOE profilometer -- Measuring dynamic vehicle loads -- AASHO road test vehicle operating costs related to gross weight -- Special studies -- Structural deterioration of test pavements: Flexible -- Structural deterioration of test pavements: Rigid -- Relationships of AASHO road test pavement performance to design and load factors -- Fractional factorial analysis for flexible pavement performance data -- Prediction of flexible pavement performance from deflection measurements -- AASHO road test principal relationships: Performance with stress, rigid pavements -- Performance of treated and untreated aggregate bases -- Prepared and spontaneous discussions including road test staff comments -- Opening remarks by Mr. Johnson -- New York State Thruway use of road test findings -- Application of road test formulas in structural design of pavement -- Road test findings utilized in analysis of Texas triaxial method of pavement design -- Application of AASHO road test equations to mixed traffic -- Use of road test equations in pavement cost allocation -- Use of road test findings by AASHO Design Committee -- Use of AASHO road test findings by the AASHO Committee on Highway Transport.- Subjects: Conference papers and proceedings.; Highway research; Test roads; Bridges;
