| 摘要： | In 2001, CDOT overlaid twelve miles of I 70 in Glenwood Canyon with a unique asphalt mix design that utilized a traditional Performance Graded Binder blended with Trinidad Lake Asphalt (TLA) and traditional aggregate blended with steel slag aggregate. This is the first project where CDOT has incorporated TLA in the mix design. There are many natural deposits of asphalt found around the world; Trinidad Lake is the most famous and has the largest commercial deposit of natural asphalt in the world. This study was designed to evaluate the performance of a pavement containing Trinidad Lake Asphalt blended with a polymer modified asphalt (PG 76-28) in combination with a very hard and angular steel slag under Colorado weather and traffic conditions. |
