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。 -

按照現行路面設計理論，路面結構各層性能正常、層間界面接觸理想、設計和施工質量良好的水泥混凝土路面，一般要經過長期使用且達到其設計使用年限后才會開裂破壞。 -
It is commonly recognized that subsurface drainage system can improve pavement performance and extend service life. as an essential part of subsurface drainage system, the layer setting and characteristics of asphalt treated permeable material directly affect the performance of subsurface drainage system, which is lucubrated in this paper. based on the typical semi - rigid pavement without permeable layer, using multilayer elastic system program, rational pavement structure with permeable layer at different locations is first analyzed
本文以高等級公路瀝青路面的典型結構形式作為未設排水層的路面結構原型，通過不同的設置層位分析對排水層的回彈模量和厚度的要求，探討設置排水層的路面結構的一些結構參數適宜的取值范圍，並在此基礎上運用灰色系統關聯分析方法，對不同設置層位的路面結構的技術指標進行比較分析，得出較優的層位設置方案。 -
By structural analysis and calculation for original highway structure without permeable layer, the critical modulus of base have been obtained which makes asphalt pavement fill different allowable stress criterion. by structural analysis and calculation for different highway structure with permeable layer, critical modulus of permeable base course are obtained to make asphalt pavement fill different allowable stress criterion. the paper also presents the tendency of structure response of different highway structure with drainable layers mainly depends on the thickness of asphalt pavement, the thickness and the critical modulus of permeable base
對于不設排水層的原路面結構，通過結構計算得出對應于不同的瀝青面層容許應力值時所需的基層臨界模量值；對于加設排水層的路面結構，通過結構計算得出對應于不同的瀝青面層容許應力值時所需的排水基層臨界模量值；加設排水層的路面結構的結構反應的變化趨勢主要取決于瀝青面層厚度、排水基層厚度和排水基層臨界模量值。 -

The pavement system with the complicated structure is always considered as a large surface layer bearing on the infinitely deep foundation. due to complexity and variety of materials and stochastic uncertainty of load boundary condition, many mathematic and mechanic problems will occur in obtaining stress and displacement solutions of the pavement system
路面體系在構造上比較復雜，它通常是一個大面層，支承在無限深的地基上，由於體系材料復雜性、多樣性和荷載邊界條件的隨機不確定性，在解算它的內力、位移時會遇到很多的數學和力學上的困難。 -
Here aiming at temperature and traffic load factors, have a systemic study about strcture ' s stress distribution. plan is to make use of ansys to calculate pavement structure ' s distortion with full grade gravelly interlayer carefully through changing each layer ' s thickness and module. next, analysize stress among bottom of surface asphalt layer and top of semi - rigitidy base. lastly. make a conclusion : how to distrube stress and strain about the structure after adding gravelly interlayer
方法是採用ansys對加設級配碎石基層半剛路面結構進行多種參數模擬計算，通過改變結構材料厚度、模量等觀察基層和面層應力變化，研究碎石基層怎樣調整結構應力而防止了溫度和行車荷載產生的過大拉應力，避免基層產生內部裂縫。
