Asphalt Institute Releases New Binder Handbook
his summer the Asphalt Institute released its newest title, MS-26, The Asphalt Binder Handbook. The 223-page book is devoted entirely to information about asphalt binders or bitumen. “This book brings together, in one location, everything about asphalt binder that the Asphalt Institute has,” said author R. Michael Anderson, P.E., director of research and laboratory services at AI.
The book is a compilation of information previously found in its existing titles such as Superpave Performance Graded Asphalt Binder Specification and Testing, Asphalt Handbook, Basic Asphalt Emulsion Manual, and others. MS26 also features new information on Multiple-Stress Creep Recovery tests, the generation of master curves, testing variability and more. “This book is for anyone in the asphalt industry who wants to know more about liquid asphalt,” said Anderson. It’s available at Amazon.com and other booksellers, as well as from the Asphalt Institute.
NCHRP Rolls Out Report on ‘Determining Highway Maintenance Costs’
arlier this year the National Cooperative Highway Research Program released a new product, Report No. 688: Determining Highway Maintenance Costs. Authored by Cambridge Systematics, Inc. with EVS, Inc., Eden Prairie, Minn., and Michael J. Markow, Teaticket, Mass., the report will be of interest to pavement preservation practioners. The report presents a practical process for determining an agency’s full costs associated with performing highway maintenance. The process can be applied to any specific maintenance activity and ensures that the resulting full cost incorporates a fair share of both maintenance program and enterprise support costs.
In addition, the report documents the application of the full cost determination process for a number of highway agencies and different maintenance activities to demonstrate the types of options, exceptions, and decisions that would be needed in order to perform the full cost calculation. The material contained in the report should be of immediate interest to state maintenance engineers and others involved in the maintenance of highway infrastructure.

Report: Smoother Roads Equal Energy Savings
new study shows that one road to energy savings could already be under the wheels of our cars: smoother pavements, reports the National Asphalt Pavement Association. Dr. Richard Willis, an assistant research professor at Auburn University, reported in July that modest improvements in the smoothness of pavements could save up to 3.7 billion gallons of gasoline and 1.3 billion gallons of diesel for the U.S. every year, a total of 5 billion gallons of fuel for the vehicles being driven on our highways. In other terms, smoothing out America’s roads and highways could save around $12.5 billion a year for the U.S. economy.
Willis and Auburn’s Dr. Rob Jackson completed an analysis of more than 20 studies from throughout the world. At NAPA’s midyear meeting Willis presented a preview of a study that will be published soon by Auburn. He reported that smoothness is a pavement characteristic that has one of the greatest impacts on fuel economy. “We know that, of all the factors that influence fuel economy — vehicle aerodynamics, engine dynamics, a ambient air temperature, tire geometry, vehicle speed, tire pressure, and so forth — there is only one that pavements can affect, and that is rolling resistance,” said Willis. “Rolling resistance can be thought of as the force required to keep tires rolling. It could also be thought
