Study of Longitudinal Joint Construction in Bituminous Concrete Pavements.

摘要

It has long been recognized that longitudinal joints between separately placed lanes of bituminous concrete have been very vulnerable to the effects of water,weather,and traffic conditions. This project was undertaken to study and evaluate several different types of joint construction techniques to aid in the future construction of more durable joints. For the purposes of this study only cold face joint construction was used,with the rolling technique varied in the second placed lane to give three methods of joint construction,the lap joint,pinched joint and the forced joint.
