| 摘要： | Tensar claims that the use of its geogrid-reinforced asphalt systems installed with standard bitumen tack coats outperformed those using higher spray rates, as well as those using polymer-modified bitumen bond coats, in independent laboratory tests. "Results show using a 1.1 l/m~2 of tack coat with asphalt geogrid reinforcement is more effective than using a 2l/m~2 spray rate and more effective than a polymer-modified bitumen bond coat, which could, in fact, affect performance, as well as being more expensive," according to Tensar asphalt reinforcement manager Tony Roe. Aecom's Pavement Design and Asset Management team was commissioned by road maintenance specialist Foster Contracting to assess the effect and performance of Tensar's Glasstex composite glass yarn grid and non-woven paving fabric on asphalt systems, incorporating either bond or tack coats. |
