This dissertation integrates the practice from the jin chao speedway . it analyses and discusses the capability , evaluation method , production , design and construct in technique for the modified asphalt and modified asphalt mixtures , the article discuss is preventing ways for the forepart damage of asphaltic roads , and also summarizes many practical conclusions from a mass of testing date . it is expected it can offer some helpful experience for modified asphaltic ' s research and engineering and practice in the future 本論文結合錦朝高速公路的實踐,著重對sbs改性瀝青和改性瀝青混合料的性能、評價方法、生產制造和設計及施工技術進行了分析和探討;在論文中,對瀝青路面的早期破壞現象的防止措施進行了全面地研究;同時,通過大量的試驗數據,總結出了很多有實用價值的結論。

Two different reinforcing methodologies are applied : modification of the overlay characteristics by adding chopped glass fibers to the hot mixture asphalt ( hma ) and reinforcing asphalt overlay with glass grids . theory of fracture mechanics ( fm ) is employed to determine crack growth rates for the suggested anti - cracking overlay systems . asphalt mixture designing tests , three point bending tests and fatigue crack propagation tests were carried out . the critical stress intensity factors kic are determined for plain and reinforced asphalt concrete . depending on the fatigue crack propagation , the crack growth rate is determined for each type of anti - cracking system and the cracking process is also analyzed . one of the significant points in this study is the attempt to give better understanding of the crack propagation for multilayer asphaltic overlay or what are suggested herein to be called composite structure anti - cracking overlay system . the results indicate that the reinforcing materials improve anti - cracking characteristics of the asphalt concrete . composite structure anti - cracking overlay gives a good solution for the reflective cracking phenomenon over old cracked pavements 利用2種不同的方法加筋瀝青罩面:在瀝青混合料中加入短切玻璃纖維改善瀝青混凝土的特性,采用玻璃格珊加筋瀝青混凝土.應用斷裂力學方法分析瀝青路面裂縫擴展機理.采用瀝青混合料設計試驗、三點彎曲試驗和疲勞裂縫擴展試驗,確定加筋瀝青混凝土的臨界應力強度因子kic ,測量每一種瀝青罩面抗裂系統的裂縫擴展速率.本研究的主要特點是提出復合型抗裂罩面系統,分析了多層加筋瀝青罩面裂縫擴展過程,推薦了若干瀝青路面抗裂系統.結果證明,加筋材料可以提高瀝青罩面的抗裂特性,復合型抗裂罩面系統能夠有效地阻止反射裂縫的擴展

Abstract : according to the charateristics of the rock fill dam with an asphaltic concrete core wall , the reasonable models are chosen to simulate the rock dam body , rigid subwall and asphaltic concrete core wall , a method is suggested to investigate the interface between subwall and core wall , the local stress distribution of the core wall is taken into consideration in the calculation 文摘:結合瀝青混凝土心墻堆石壩的結構特點,對堆石壩體、剛性副墻、瀝青混凝土心墻分別采用了合理的計算模型,提出了剛性副墻與心墻接觸面的模擬方法,研究了心墻的局部應力問題,并用該方法對某瀝青混凝土心墻壩進行了計算,得出了一些規律性結論

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 定期的養護與維修可以延長瀝青路面的使用壽命,及時地在瀝青路面上加鋪罩面,不僅可以增強路面強度,還可改善路面的使用性能,而不必做大量的重建工作,其厚度也小于重建施工的厚度,因此對于已破損的路面,采用瀝青混凝土罩面常可以提供最經濟的修復形式。

Sbs modified asphaltic concrete roads has the predominant capability than other traditional asphaltic roads and other modified asphaltic roads . at present , it has gained extensive attention and altitudinal regard from the chaussee industry Sbs改性瀝青混凝土路面由于具有其他傳統瀝青路面和其他改性瀝青路面無法比擬的優越性能,目前已得到了公路工程界的廣泛關注和高度重視。
