Evaluation of the Specifiion for Flat and Elongated

ConnDOT specifiion allows for no more than 10 percent flat and elongated particles utilizing a 3:1 ratio. It has been speculated that this specifiion may not be achievable by most HMA producers in Connecticut. The research team evaluated specifiions from numerous regional state agencies for comparison with the ConnDOT specifiion.
