EFFECTS OF IDAHO AGGREGATE GRADATION ON ASPHALT PAVING MIX

This study is intended to investigate the effects of Idaho aggregate gradation on paving mix design. Four Idaho source of aggregate were chosen for the study. For each source, three different gradations were made and subjected to Hveem test. It appeared that gradation of each source has its own effect on the asphalt paving mix. It is found that for Source Bk-117, gradation of 1/2" aggregate should be kept close to the lower limit of the gradation guide, the one that contains more coarse aggregate. Aggregate gradation from Source Ad-56 also should contain more coarse aggregate and this source is good for use in pavement under heavy traffic. Three-quarter aggregate from Source TF-25 also should be kept close to the lower limit of the gradation guide. (Author)
