为了更好地利用石灰粉煤灰稳定风积沙填筑沙漠地区高速公路底基层,研究了石灰粉煤灰稳定风积沙作为底基层材料的性能。聚丙烯纤维作为外加材料加入石灰粉煤灰稳定风积沙中(充分利用纤维的韧性和抗拉强度来增加混合料的强度和抗拉能力)进行路用性能试验。试验结果表明:合适长度,一定量纤维的掺入有利于提高二灰稳定风积沙的抗拉性能及抗收缩性能,从而为工程实践提供一定的依据。
為瞭更好地利用石灰粉煤灰穩定風積沙填築沙漠地區高速公路底基層,研究瞭石灰粉煤灰穩定風積沙作為底基層材料的性能。聚丙烯纖維作為外加材料加入石灰粉煤灰穩定風積沙中(充分利用纖維的韌性和抗拉彊度來增加混閤料的彊度和抗拉能力)進行路用性能試驗。試驗結果錶明:閤適長度,一定量纖維的摻入有利于提高二灰穩定風積沙的抗拉性能及抗收縮性能,從而為工程實踐提供一定的依據。

In order to better use lime flyash to stabilize the subbase of the express highway in the desert area filling with aeolian sand ,the properties for using the lime flyash to be the subbase material are studied here ,and the road-used per-formance tests for adding polypropylene fiber into the lime flyash as the extra material are conducted (fully using the fiber’ s toughness and tensile strength to increase the mixing material’s strength and tensile capacity ) .The test results show that the appropriate length and a certain amount of the fiber could help to improve the lime flyash’s tensile properties and anti-shrinkage properties in stabilizing the aeolian sand ,so as to provide a certain basis for engineering practices .
