RATIONAL DESIGN METHOD OF HOT MIX ASPHALT BASED ON CALCULATED VMA
VMA (Void in Mineral Aggregate) is an important volumetric factor for design of hot mix asphalt. However, this VMA is usually obtained from laboratory test results of compacted specimen of hot mix asphalt. If VMA would be estimated without preparation of these specimens, design of hot mix asphalt to obtain both an optimum asphalt content and necessary void content would be rational. This paper presents an equation to obtain terminal VMA value for each aggregate gradation curve. This equation was derived from deductive analysis of aggregate mixture tests and is then verified for typical types of asphalt mixture such as dense graded, SMA and porous asphalt. In this method, VMA is calculated and air volume content is decided for aggregate proportions. Binder content to fill the volume of VMA minus air void content is determined. Laboratory test is performed to check the proposed mix design and whether degree of compaction is equal to approximately 98%. For the covering abstract see ITRD E121480.
