Life Cycle Costs For Asphalt-Rubber Paving Materials

$7.00

Description

Life cycle cost analysis (LCCA) is recognized by public agencies as an effective tool to assist in the selection of construction, rehabilitation, and maintenance treatments. For mixtures of asphalt rubber binders and aggregates to be more widely accepted, they must be shown to be cost effective (lower LCC than the alternates). This paper presents:
– a brief history of asphalt rubber use and cost information
– a description of the life cycle cost process used in this paper
– comparative results to evaluate the LCC for pavements containing conventional binders with similar applications containing asphalt rubber binders.

The findings indicate asphalt rubber is cost effective in many of the applications used by the state highway agencies of Arizona, California, and Texas.
