Abstract

A shell sliding plate microviscometer with improved steel plates was used for low-temperature testing of asphalt but was found to be inadequate for the stresses imposed. There is need for low-temperature viscosity values to establish properties influential in determining resistance to thermal cracking of asphalt concrete pavements. Manufacturers should redesign a microviscometer to withstand the stresses imposed by low-temperature testing.
