This report presents the preliminary results of a study of the effects of pavement structural response on excess fuel consumption (EFCS), which is defined as the additional fuel required to propel a vehicle on an “imperfect” pavement compared to the amount required on an “ideal” pavement. The study compared EFCS for a set of asphalt-surfaced test sections with a pavement with no structural response as well as with the effects of roughness and macrotexture on EFC.
EFCS was calculated using three different models for a factorial that included seventeen asphalt-surfaced pavement field sections on the California state highway network with different structure types that were characterized by their viscoelastic properties. The results of the modeling were used to simulate annual EFCS for a factorial of vehicles, traffic flows, speed distributions, and climate regions typical of California. The sensitivity of EFCS to the variables in the factorial was analyzed, and the effects of structural response on EFC were compared with those of roughness and macrotexture to determine whether structural response is sufficiently important to warrant a second phase of the project to validate and calibrate the models using field test sections and instrumented vehicles.
It is recommended to complete models for concrete pavements in addition to asphalt-surfaced pavements, to consider multiple layers in the asphalt, particularly near the surface to better evaluate the effects of rubberized asphalt surface materials, and to check the effects of full dynamic pavement modeling (inertial effects in the pavement) on more than the one section analyzed. It is also recommended to begin field validation and calibration of the models and rerun the simulations with the improved and calibrated models for all pavement surface types.

A deflection bowl is formed on pavement surface due to vehicle/traffic/axle load, and excessive fuel is consumed by the vehicle to climb/drive the hill/deflected bowl. The goal of the study is to investigate the effect of pavement structural response on the vehicle energy consumption and emissions. Phase I of the study is completed where Massachusetts Institute of Technology (MIT), Michigan State University (MSU) and Oregon State University (OSU) along with University of California Davis (UCDavis) have developed three different models to predict the effect of pavement structural response on vehicle fuel consumption. Phase II is close to completion where field vehicles fuel consumption is being measured on different sets of pavements in California.

List of current projects
Developing a generalized methodology to compare the environmental impacts of in-place recycling and conventional paving techniques. The in-place recycling techniques include both hot-in-place recycling (HIPR) and cold-in-place recycling (CIPR) that local and state roadway agencies have been using as part of their preservation and rehabilitation programs.

Federal Highway Administration (FHWA), A Life-Cycle Methodology for Energy Use by In-Place Pavement Recycle Techniques
Writing guidelines of how to do a pavement LCA when it comes to any pavement type such as high and low traffic volume roads, airfields, bike paths, pedestrian paths, streets etc. The guidelines are being developed/written for California Transportation Admins (Caltrans), Federal Highways (FHWA) and Federal Aviation (FAA).
Guidelines for Pavement Life Cycle Assessment
In this project, evaluation of fracture and moisture damage performance of wax modified asphalt (WMA) mixtures has been investigated. Furthermore, low temperature cracking performance of WMA has been examined utilizing the Superpave indirect tensile test. Different bitumen type and modified binders, such as polymer modified, mastic and wax modified binders, were evaluated in the laboratory and their corresponding asphalt mixtures.
