SPR-4325: Development of Volumetric Acceptance and Percent Within Limits (PWL) Criteria for Stone Matrix Asphalt (SMA) Mixtures in Indiana

Section 410 has a discrepancy between stone mix asphalt (SMA) design criteria and its acceptance. SMA adjusted pay points in Section 410.19 are not based on robust statistics. There is a need for the Indiana Department of Transportation (INDOT) performance-related SMA percent within limits (PWL) pay factors in order to assure pavement quality that INDOT invests for.
