摘要

The 24 papers in this report deal with the following areas: compactibility of asphalt paving mixtures and relation to permanent deformation; rutting properties of a dune-sand paving mixture; visco-elasto-plastic constitutive law for a bituminous mixture under repeated loading; modification of the asphalt institute bituminous mix modulus predictive equation; effect of emulsified binders on characteristics of bituminous mixtures; fundamental comparison of the flexural and indirect tensil tests; test for efficiency of mixing of recycled asphalt paving mixtures; cold-mix recycling of asphalt materials: an application to low-volume roads; evaluation of long-term hehavior of cold recycled asphalt mixture; effect of specimen size on marshal test results of cold-mixed, asphalt-stabilized bases; development of rational pay adjustment factors for asphalt concrete; laboratory investigation of the use of foamed asphalt for recycled bituminous pavements; foamed-asphalt paving mixtures: preparation of design mixes and treatment of test specimens; use of foamed asphalt in recycling of an asphalt pavement; structural properties of laboratory mixtures containing foamed asphalt and marginal aggregates; sprinkle treatment in Illinois; experience in Iowa with sprinkle treatment of asphalt pavements; sprinkle treatment of asphalt pavements; evaluation of moisture effects on asphalt concrete mixtures; procedure for predicting laboratory retained strength cut-off and additive benefit-cost ratios of moisture-damaged asphalt concrete; stripping of asphalt pavements: state of the art; investigation of moisture damage to asphalt concrete and the effect on field performance--a case study; availability of sulfur for sulfur-extended asphalt paving in Washington State; and, a sulphlex mixture design method based on the indirect tensile test.
