Research Brief

This research brief summarizes findings from a study in which researchers investigated the use of higher percentages of reclaimed asphalt pavement and asphalt roofing shingles as a partial replacement for the virgin binder in new asphalt mixes.

Integrated and Data-Driven Transportation Infrastructure Management through Consideration of Life Cycle Costs and Environmental Impacts

Research Product Type

Dissertation / Thesis

The main goal of this dissertation was to develop frameworks, quantitative models, and databases needed to support data-driven, informed, and integrated decision-making in managing the vast transportation infrastructure in California.

International Symposium on Pavement, Roadway, and Bridge Life Cycle Assessment 2020

The goal of the symposium was to share and discuss recent advances in life cycle assessment (LCA) for pavement, roadways, and bridges, and review and discuss the current status and future developments, standardization and implementation of pavement, roadway, and bridge LCA.

Investigation into Aging Mechanisms and Performance of Rubber-Modified Asphalt Binder and Mix

Research Product Type

Dissertation / Thesis

This study aimed to explore the mechanism of rubber modification on aging resistance for rubber-modified binders, and also evaluated the performance-related properties of dense-graded asphalt mixes using smaller quantities of CRM than are used in current applications.

Investigation into the Aging Mechanism and Performance of Asphalt Mix Containing Crumb Rubber Modifier

Principal Investigator Yanlong Liang, PhD
University of California, Davis

This study aims to investigate asphalt binder and mix aging mechanism, especially for the asphalt containing crumb rubber modifier, and evaluate the aging effects on the asphalt mix performances. This study also aims to further evaluate the performance of the asphalt mix containing crumb rubber modifier, including the rutting resistance, fatigue life, and thermal cracking resistance.
