The Performance of Overlay Treatments and Modified Binders Under Accelerated Loading

Callington ALF Trial : Final Summary Report

During the 1980s there was an increasing trend in the occurrence of fatigue cracking of asphalt surfacings as the predominant failure mode on heavily trafficked pavements in South Australia. Whilst the introduction of mechanistic design methods had helped to provide an improved understanding of the high sensitivity of asphalt surfacing life to the stiffness and fatigue properties of the asphalt materials, it was recognised by the late 1980s that there was a need to validate these design inputs for materials used in Australia because of their influence on design life and pavement cost. The introduction of new types of modified binders posed an additional problem in that they did not conform with existing experience and it was difficult to assess the required thickness and conditions under which they are cost effective. Accordingly, there was seen to be a need to derive design criteria under field conditions and establish by direct field correlation the relative benefits of different material types. Between July 1988 and October 1989 the South Australian Department of Transport and ARRB Transport Research conducted a series of full-scale pavement tests using the Accelerated Loading Facility (ALF). Testing was carried out on a section of distressed pavement that had been rehabilitated by a variety of asphalt treatments. Over 3.3 million loading cycles were completed during 17 experiments on different asphalt rehabilitation configurations. This report summarises the results of the trial. (a).

NORTH BEACH ROAD

A tiny community tucked away in the Southeast corner of Idaho, next to beautiful Bear Lake with a predominately Mormon population, is about to learn the difference between the religious and the secular. Two capital crimes turn this little town and surrounding community into a tinderbox of questions and fear concerning both. Sheriff Ned Williamson, a former Marine and his trusted friend, the coroner, Winston Rand need to solve two crimes. Are they related or separate? Are outsiders responsible? And is the local patriarch, Willard Jensen, who he seems to be? Will his son and daughter, Stacy and Stanley find out the truth about him? Meanwhile the sanity of a young girl, Marcy McFadden, hangs in the balance. What is going on with her sessions with the local Bishop? How far does the word ‘trust’ go? Read and find out.
