DEVELOP IMPROVED ASPHALTIC CONCRETE MIXTURE USING MATERIALS AVAILABLE TO NEBRASKA VOLUME I; VOLUME II--APPENDICES
An investigation to develop improved asphaltic concrete mixtures was conducted during the period July 12, 1972 through October 31, 1973. Forty-seven laboratory mix designs were investigated utilizing materials available to Nebraska. Emphasis was on mixtures which are cost competitive with presently utilized paving mixtures but which exhibit potential for improved resistance to plastic deformation and studded tire wear as well as providing adequate skid resistance. Theprincipal investigative tool was the Marshall Apparatus. Tests on mixtures and materials were consistent with either ASTM or NDR standard procedures with immersion-compression, stripping and air permeability tests supplementing determination of Marshall properties. A conclusion is that the present Nebraska specifications for Type B aspahltic concrete is capable of producing durable, rut resistant pavements with good anti-skid properties but that the potential exists for the use of lower cost materials which exhibit some or all of these same desirable properties. Recommendations are made for specifications which would permit utilization of more widely available sand-gravel aggregates of finer grading in Type B mixes.
