| 摘要： | There are a few common themes in the bitumen technology stories in this issue. One is the slow spread of warm mix; in the UK its use is moving from national to regional roads and in South America, a trial to combine RAP and warm mix could encourage its wider application. We also see the impact that private concessionaire companies can have on advancing the adoption of technologies. Argentina, Autopistas del Sol is being pro-active in reducing cost and carbon emissions while maintaining performance, and in the UK, Connect Plus is pushing ahead with Shell's AgeSafe technology in a bid to replace surfaces less often, potentially saving cost, carbon and congestion. Meanwhile, a study in the state of New York demonstrates why road authorities everywhere should look into chipsealing sooner rather than later. A ground-breaking trial in Argentina has seen the combination of warm mix technology and RAP in the wearing course of the busy Pan-American Highway, Route 9. Working for highway operator Autopistas del Sol (Ausol), contractor Construcciones Ingevial was able to use RAP from the same highway to produce the mix which contains a modified bitumen binder. |
