Book Description
It is generally known that the behavior of asphalt paving mixtures under conditions of induced stress is affected by the response of the asphalt cement in the mix. During the service life of the pavement, asphalt is exposed to low temperatures, which tend to alter its rheological response. It is important to study the low-temperature rheology of asphalts to gain a better understanding of the complex factors that affect the low-temperature behavior of flexible pavements. A storehouse of information and research data pertaining to low-temperature properties of paving asphalts exists in the literature. However, much of the data is fragmented and scattered. This brief state-of-the-art report provides as many references as possible for each test parameter so that the reader can retrieve pertinent information in a specific area of interest.

Book Description
A dozen papers from a December 1993 symposium in Dallas/Fort Worth, Texas. Among the topics are why the new proposed rheological properties of asphalt binders are required and how they compare to conventional properties, the development and use of the SHRP direct tension specification test, oxidatio

Book Description
This paper, which is the first of a proposed series, reviews selected published information on the low-temperature flow properties of asphalt cements obtained by creep procedures and dynamic techniques over temperatures below 25°C (77°F) and down to -20°C (-4°F) and lower. A comprehensive summary is given with comments on the magnitudes of the reported viscoelastic parameters (elastic, stiffness, and viscosity) and relevance of the results to other test properties. It is suggested that simplifying approximations in available apparatus may be equally useful for evaluating the rheological creep behavior as obtained in constant stress test modes. These suggestions are implemented by experimental creep measurements on two paving and two roofing asphalts over temperature ranges from 150 down to -5°C (302 to 23°F). It is demonstrated that a reasonably correct fit of the data results for a Maxwell-Kelvin modified five-parameter model. It is recommended that the use of stiffness values as a function of time together with a power law relation for viscosity is a realistic approach for evaluating low-temperature properties of asphalt cements.
