耐化學腐蝕灰漿薄漿及整塊鋪面石料抗拉強度的標準試驗方法It proves that adding up fiber and modified asphalt in the common asphalt mixture can decrease the brittle point temperature and strength the ability of resisting cracking. fiber - reinforced asphalt concrete and glass fiber grid which has been set between the road base and overlay can delaying reflection cracking effectively
試驗證明,在普通瀝青混合料中加入聚酯纖維以及使用改性瀝青可脆化點溫度降低,增強低溫抗裂性,加入goodroad聚酯纖維和在基層與面層之間鋪設玻纖格柵可有效抑制反射裂縫,值得推廣。Based on the studies, it is proved that lime fly - ash mixture is provided with more time to compact during construction compared with other base materials in forming even higher structure strength but not in reducing strength within 1 ~ 3 days period of time. meanwhile, structure strength of the mixture which has been destroyed by some reasons can be recovered in a great extent if original structure is regained. on the other hand, during the high temperature summer season or under other conditions promoting the mixture to form strength, continuous construction process between lime fly - ash base course and bituminous pavement can be carried out to complete the building process in short time
確認二灰基層材料與其它類型的基層材料相比,在施工時具有較長的施工碾壓成型時間,在一定時間里延遲成型的二灰基層強度不僅不降低,反而還有一定程度的提高;與此同時早期受到破壞的二灰材料在恢復整體性的條件下,結構強度能夠在很大程度上得到再恢復;另一方面,在夏季高溫季節以及在強化基層強度形成的前提下,二灰類基層和瀝青面層可以採用連續施工的方式在較短的時間里完成路面鋪築工作。Periodic maintenance and rehabilitation can prolong the road ' s service life. an asphaltic overlay is applied to the old pavement surface in good time, which not only enhances the strength of the pavement, but also improves the using performance of the old pavement instead of doing lots of rebuilding works. therefore, the thickness of asphalt concrete overlays is less than the thickness of the reconstructed pavement
