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。 -

由於建築物的破壞往往始於裂縫，所以人們一般把裂縫的出現視作危險的徵兆，裂縫使人們產生恐懼感。隨著國家經濟的發展，工程建設規模越來越大，工程結構朝著大型化、復雜化的方向進展，隨著混凝土原材料的不斷更新，混凝土強度等級的不斷提高，在實際工程上出現了大量的裂縫問題。近年來隨著國家經濟的進一步發展，用於工程建設的用鋼量日趨增大，而國家的鋼材供應量不能滿足日趨增大的市場需求量，導致鋼材的價格不斷上漲，這就要求我們在節約鋼材用量的基礎上來設計控制工程中的裂縫問題，這也就給裂縫研究提出新的課題。 -
