  1. Through the experimental research, we think : the technological capacity of fiberglass asphalt macadam if weaker than asphalt macadam, however, if use elasticized capacity to solve blending technological problem. adjust the breed of fiber silk, extend its diameter, its paving capacity is still worth exploring, asphalt - rubber macadam structure lager have good deformed - become capacity and crazed - resistance capacity, small gap rate. good water - resistance capacity, good hot - stability and simple construction technology. therefore. pitch rubber spall is a good cover material which is suitable for the second class or lower whose asphalt pavement has split open because of fatigue. and is the good structural measure of preventing half - rigidity grass - roots unit shrink - rift reflecting. pave a thin layer of pitch rubber spall between asphalt - type pavement layer and half - rigidity basic level, although the cost of building is higher than paving togongbu in the middle, the construction technology, crazing - resistance and water - resistance are better than togongbu, not only could reduce greatly the reflex of half - rigidity grass - roots unit material, long then the use lifespan of pavement, but also it is possible to reduce suitably the thickness of asphalt mixture layer, though the cast of building in the early days becomes more, in the long - term opinion, it have fully important technological and economical significance

    通過試驗研究認為：玻璃纖維瀝青碎石的技術性能不如瀝青碎石好，但路用彈性性能較好，如能解決拌和工藝問題，調整纖維絲的品種，增大其直徑，其路用性能仍值得探討，瀝青橡膠碎石結構層具有變形性能和抗裂性能良好，空隙率小，防水性能好，熱穩定性較好，施工工藝簡單的特點，因此，瀝青橡膠碎石是二級及二級以下公路因疲勞而開裂的瀝青路面的良好罩面材料，也是防止半剛性基層收縮裂縫反射的良好結構措施，在瀝青類路面面層和半剛性基層之間夾鋪瀝青橡膠碎石薄層，雖然造價比夾鋪土工布高，但其施工工藝，抗裂性能和防水性能均優于土工布，不僅可以大大減少半剛性基層材料的反射裂縫，延長路面使用壽命，而且可能適當減薄瀝青混合料面層的厚度，雖然初期造價有所增加，從長遠來看，具有十分重要的技術和經濟意義。
  2. In accordance to the defects presented in using the chinese road asphalt technical standards to assess the asphalt performance as well as the facts that the shrp test equipment of usa can not be widely employed in china since its being very expensive, the shrp rheological concept is utilized in the research project to carry out the exploration of the rheological properties of modified and non - modified asphalt by using conventional tests such as penetration and ductility. the conclusions obtained by using the conventional test rheological index to assess asphalt performance are compared with those by using the shrp rheological index and their certain correlation are found

    針對目前我國道路石油瀝青技術標準評價瀝青路用性能存在的種種缺陷，以及美國shrp試驗設備因其昂貴性而暫時無法在國內大量推廣應用這一事實，本課題試圖利用shrp流變思想，採用針入度、延度等常規試驗設備進行改性及非改性瀝青流變特性的研究，並將常規試驗流變指標評價瀝青路用性能的結論與shrp流變指標評價結論作比較，找出它們之間的相關關系，從而肯定了採用常規試驗設備進行瀝青流變特性及路用性能研究的有效性。
  3. And reached the following specific conclusions : rubber content with the increase of resistance to ageing rubber modified asphalt increased ageing after less than for low - temperature service, the quality of reduced losses, soften point increase needle into a normal degree. summed up the aging asphalt and modified asphalt laws made spent rubber for asphalt modified agents, the principles of the size options and dosage of rubber powder for spent rubber modified asphalt road asphalt in the application provided a good technical support

    得出了隨膠粉含量的增加膠粉改性瀝青的抗老化性能提高，老化后低溫延度比減小、質量損失量減小、軟化點提高，針入度呈正態分佈及改性瀝青老化的規律，提出了廢膠粉用作瀝青改性劑時粒徑選擇和摻量確定的原則，為廢膠粉改性瀝青在公路瀝青路面中的應用提供了良好的技術支持。
  4. 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。
  5. 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，其厚度也小於重建施工的厚度，因此對于已破損的路面，採用瀝青混凝土罩面常可以提供最經濟的修復形式。
  6. Based on above research results, mechanism of the mixture features is studied by some methods, such as chemical analysis, electron microscope and x - raying and so on to explain the characteristic principle. research conclusion confirms it is the high content of useful fly - ash composition and the high structure polymeric degree that lime fly - ash mixture not only can present possibility of delayed base compaction and strength regeneration compared with other base materials but also can take continuous construction process to compact base course and pavement

    認為正是粉煤灰具有的高比例有效成分含量，以及結構上呈現的高度聚合的穩定性，使粉煤灰石灰混合料與其它常見的半剛性基層材料相比，不但能表現出顯著的碾壓成型的可延遲性、結構強度的可恢復性，而且還具有在一定條件下能夠採用基層和瀝青面層連續施工的獨特性質。
  7. In this article we will prove the feasibility of highway construction rock material production base in hubei province from three aspects : economy, technique and finance. then we will researche the management of rock material production base from two points of view : property right dividing and corporate governance. and we hope the production base may improve the capacity of pitch mixture and prolong the pitch pavement life by modern production technics, scientific composing design and high economic income and serve for the construction of high - grade highway in hubei province

    本文從經濟、技術和財務三方面論證了建立湖北省公路建設石材生產基地建設方案的可行性，並從產權界定和公司治理結構兩個角度對石材生產基地的運營做了進一步深入的研究，希望以精良的礦料制備、科學的組成設計和較高的經濟收益，來改善瀝青混合料的路用性能，延長瀝青路面的使用壽命，更好地服務于湖北省的高等級公路建設。
