AGGREGATE/RAP SAMPLING Aggregate samples may be obtained from stockpiles, belts, or hot bins depending on the type of plant and control of aggregate gradation selected. The procedures for these methods of sampling are described in Chapter 2. If RAP is used in the mixture, the procedure for sampling this material is ITM 207. BINDER SAMPLINGMeasuring the “impact”,While impact measurement offers benefits for multiple stakeholders in an impact investment, there is a need for greater alignment for incentives to devote resources to measuring impact. Factors that contribute to low incen-tive to measure impact include: • Perception of low value in impact
