Stability Investigation of Bituminous Pavements

By Kentucky Highway Materials Research Laboratory


This stability investigation was started by the Bituminous Division of the Highway Materials Research Laboratory, Lexington, Kentucky during the month of October, 1944, and was completed the first of March 1945. The purpose of this investigation was to develop information on the design and control of asphalt pavements. The data presented may be used to compare mixes made from commercial aggregates with mixes containing local aggregates. It is believed that sufficient amount of reliable data is presented in this report to enable the design engineer to use the Marshall stability equipment and testing procedure to select the best available aggregate combination, gradation and bitumen content. This investigation includes a series of tests conducted on commercial aggregates now being used by the Department of Highways for bituminous pavements. The following commercial aggregates were included in this series of tests; river gravel and sand, limestone and sand, slag, and limestone. Three gradations were used for all aggregate combinations. These three gradations were selected to represent the minimum, average, and maximum percent passing each sieve size designated by the Department of Highways Class I, Type B, Specification
