Abstract:This report describes the development and establishment of a proposed Simple Performance
Test (SPT) specification in order to contribute to the asphalt materials technology in the state of
Michigan. The properties and characteristic of materials, performance testing of specimens, and field
analyses are used in developing draft SPT specifications. These advanced and more effective
specifications should significantly improve the qualities of designed and constructed hot mix asphalt
(HMA) leading to improvement in pavement life in Michigan. The objectives of this study include the
following: 1) using the SPT, conduct a laboratory study to measure the parameters including the dynamic
modulus terms (E*/sinϕ and E*) and the flow number (Fn) for typical Michigan HMA mixtures, 2)
correlate the results of the laboratory study to field performance as they relate to flexible pavement
performance (rutting, fatigue, and low temperature cracking), and 3) make recommendations for the SPT
criteria at specific traffic levels (e.g. E3, E10, E30), including recommendations for a draft test
specification for use in Michigan. The specification criteria of dynamic modulus were developed based
upon field rutting performance and contractor warranty criteria.
