EC130温拌剂掺量对温拌沥青混合料性能影响研究
|
摘要
设计制作5种EC130温拌剂掺量的温拌沥青混合料(WMA)试件及1种热拌沥青混合料(HMA)试件,通过马歇尔试验、浸水马歇尔试验和高温车辙试验研究EC130掺量对WMA路用性能的影响.结果表明:温拌剂的掺入对混合料最佳油石比影响较小;当EC130掺量为0%～0.5%时,WMA高温稳定性随EC130掺量增加而增加,其稳定度与水稳定性呈现先增大后减小的趋势;与HMA相比,高EC130掺量提高了WMA的高温性能;温拌剂最佳掺量为0.3%,此时WMA达到综合性能最优.
The influence of EC130 contents on the pavement performance of warm mix asphalt(WMA) were investigated by Marshall test, Immersion Marshall test and Rutting test. The tests were performed on WMA with five foam warm additive EC130 contents considered and hot mix asphalt(HMA). The test results indicate that the incorporation of warm additive has less effect on the optimum asphalt-aggregate ratio. In the range of 0% to 0.5% EC130 dosage, high temperature stability of WMA increases with the increase of the EC130 content. Stability and water stability appear to increase first and then decrease. WMA at high EC130 content achieves better high temperature performance than HMA. The optimum content of warm additive is 0.3%. And at this point, WMA achieves the best comprehensive properties.
