Research on the Design Method of Asphalt Mixes in Permafrost Region

摘要

Considering special climatic environments along the Qing-Zang Road, this article makes a study of the design method of asphalt mix in permafrost regions. Based on lab tests and experimental roads outcomes, it presents Marshall technical requirements for asphalt mixes in permafrost regions and technical requirements for road performance, and provides an approach to determine asphalt content.
