Cold-Mix Asphalt Concrete Surfacing.

摘要

A contributor to air pollution has been the manufacturing of hot asphalt concrete mixtures. Therefore,the California Department of Transportation initiated a project to determine,by field trials and evaluation,if cold mix asphalt concrete could be used to reduce pollution and,at the same time,provide a durable asphalt concrete pavement. In conjunction with this field work,laboratory work on the design of asphalt concrete mixtures containing emulsified asphalt was also accomplished. During the field studies,laboratory studies with various emulsions,aggregate gradations,and methods of compaction were also undertaken in an attempt to provide an improved method of laboratory mix design. Although this goal was not achieved completely,some valuable data and a better understanding of emulsion mixtures was obtained.
