WebMay 18, 2024 · Flakiness index is the percentage of stones in an aggregate consisting of an average least dimension less than 0.6 times the average dimension of stones. Elongation index is the total weight of the material retained on the various length gauges that are expressed as a percentage of the total weight of the sample is gauged. WebElongation value is 0% because the aggregate is rounded so no any retain value. Aggregate quality for road construction will also influence the road performance. The flakiness and elongation rocks are not suitable for road construction because this type of rocks will make the road surface not balance and easy to damage. 9.0 Reference a. list of equations word https://shconditioning.com
