摘要
对DE—99Ⅰ型硅藻土改性剂改性沥青及沥青混合料进行了一系列室内试验,包括沥青的技术性能试验、沥青混合料的马歇尔试验、高温车辙试验、低温弯曲试验和残留稳定度试验等,结果表明:在沥青中掺入DE—99Ⅰ型硅藻土改性剂,可使沥青及沥青混合料的高温性能得到一定的改善,将其应用于沥青路面大修工程中,取得了良好的效果。
A series of tests on the DE-99Ⅰ diatomite modified asphalt and mixtures, including asphalt properties, Marshall test, rutting test at high temperature, flexural beam test at low temperature, and retained stability, were conducted. Results of the laboratory tests showed that the stability at high temperature of the DE-99Ⅰ diatomite modified asphalt and mixtures was remarkably improved, while field applications of the ma?terials to rehabilitation of asphalt pavements confirmed the effect.
