采用不同 LDHs改性剂掺量的 LDHs/SBS改性沥青制备 LDHs/SBS沥青混合料，通过一系列试验，研究了LDHs改性剂不同掺量对 LDHs/SBS沥青混合料性能的影响。研究结果表明：沥青混合料的稳定性随 LDHs 掺量增加而提高并且体积性能指标不变；LDHs 的加入能改善沥青混合料的水稳定性，但加入量超过5%时改善能力减弱；随着 LDHs掺量的增加，沥青混合料的高温抗车辙性能提高。
採用不同 LDHs改性劑摻量的 LDHs/SBS改性瀝青製備 LDHs/SBS瀝青混閤料，通過一繫列試驗，研究瞭LDHs改性劑不同摻量對 LDHs/SBS瀝青混閤料性能的影響。研究結果錶明：瀝青混閤料的穩定性隨 LDHs 摻量增加而提高併且體積性能指標不變；LDHs 的加入能改善瀝青混閤料的水穩定性，但加入量超過5%時改善能力減弱；隨著 LDHs摻量的增加，瀝青混閤料的高溫抗車轍性能提高。

This paper aims at manufacturing different content LDHs modified SBS asphalt and researching the prop-erties of LDHs/SBS asphalt mixtures,studying the influences of LDHs on the performances of the asphalt mixture. The results showed that:as the increasing of LDHs,stability of asphalt mixture increased,and LDHs/SBS asphalt mix-ture volume performance has not been changed.LDHs improved the water stability properties of the asphalt mixture, but after 5% content,water stability of the asphalt mixture decreased.The high-temperature stability of the asphalt mixture increased,as the increasing of LDHs.
