【摘要】：擬對水性環(huán)氧乳化瀝青的路用性能及其微表處的抗車轍性能進行評價。通過粘結(jié)強度試驗、拉伸試驗以及儲存穩(wěn)定性試驗對水性環(huán)氧乳化瀝青的路用性能進行評價,并通過輪轍變形試驗及車轍試驗評價其微表處混合料的抗車轍性能。試驗結(jié)果表明:水性環(huán)氧乳化瀝青的性能隨著環(huán)氧摻量的增加而提高,與普通改性乳化瀝青相比,環(huán)氧摻量為20%時,25℃的粘結(jié)強度提高131%,45℃的粘結(jié)強度提高478%;拉伸強度提高6倍;斷裂伸長率降低88%,微表處的動穩(wěn)定度提高2.5倍,輪轍橫向變形降低了75%。當水性環(huán)氧摻量超過30%時,經(jīng)24 h靜置后后會出現(xiàn)析出現(xiàn)象,最終確定水性環(huán)氧摻量不宜超過30%。
[Abstract]:The road performance and rut resistance of waterborne epoxy emulsified asphalt are evaluated. The pavement performance of water-borne epoxy emulsified asphalt was evaluated by bond strength test, tensile test and storage stability test, and the rut resistance of the micro-surface mixture was evaluated by rut deformation test and rutting test. The experimental results show that the properties of waterborne epoxy emulsified asphalt increase with the increase of epoxy content. When the epoxy content is 20%, the bond strength at 25 鈩，
