LOW-TEMPERATURE MECHANICAL PROPERTIES OF ASPHALT CONCRETE
Low-temperature transverse asphalt pavement cracking is sometimes observed in the colder regions of the U.S., much of Canada and other regions with similar or colder climates. Besides climatic effects a number of factors are known or thought to influence the rate and extent of low-temperature transverse pavement cracking. These include asphalt properties, subgrade type, mix properties, mix design, pavement thickness, age, and traffic effects. A number of studies indicate that a major factor in the occurrence of lowtemperature transverse cracking is the low-temperature stiffness of the asphalt concrete. Because of the considerable effect that the asphalt has on asphalt concrete tiffness, asphalt properties have received the most attention in studies on low-temperature transverse cracking, leading to the development of criteria to control low-temperature cracking based solely on asphalt properties. This report covers the following areas: equipment and procedures, modulus and fracture strength, low-temperature cracking predictions, and cold computer program and nomograph-predicted cracking temperatures. Includes references.
