Akehurst, Troxler Electronic Laboratories Inc.: "The developments we see include permeability, stiffness/modulus, Warm Mix asphalt, and shear measurements for mix designs."
Arbelaez, InstroTek Inc.: "Our company actually has two pieces of equipment that can be used for both mix design and performance testing. The SPT-Asphalt Performance Tester has been heavily backed by FHWA as the future of asphalt performance testing. In the future, we see this product being a staple of any asphalt lab much like a gyratory compactor or NCAT Furnace.
"The CoreDry Rapid Asphalt Drying System is also a laboratory product that uses a method of drying asphalt cores that is super fast which contractors like extremely accurate, and does not harm the sample which DOTs like. Indiana DOT is one of the first DOTs to experiment with asphalt warranties. They have adopted this drying method and now have a CoreDry in each of their district labs."
