pavement life study 中文意思是什麼
pavement life study
解釋
路面使用壽命研究-
But, for the reflective cracking of asphalt pavement with half rigid base course and the cracking of the ac overlay above joints ( cracks ) in existing pcc pavement, the results of research show that the fatigue life of ac layer is mainly the life of the crack propagating stage. so the theory and method of fatigue destructive mechanics ( fatigue fracture mechanics and fatigue damage mechanics ) should be used to study and design the pavement structures instead of traditional fatigue mechanics
而對於半剛性基層反射裂縫和舊水泥混凝土路面瀝青混凝土加鋪層接縫(裂縫)開裂,研究發現,瀝青結構層的疲勞壽命主要為裂縫擴展階段的壽命,此時不應採用傳統的疲勞力學進行研究和結構層設計,而應採用疲勞破壞力學(疲勞斷裂力學和疲勞損傷力學)理論與方法。 -
In this paper, the theory and method of fatigue damage mechanics are adopted to study the fatigue damage behavior of asphalt mixture and the fatigue failure of asphalt pavement and predict the fatigue life of ac overlay on existed pcc pavement
本文應用疲勞損傷力學理論與方法對瀝青混合料的疲勞損傷特性、瀝青類路面疲勞破壞以及舊水泥混凝土路面瀝青混凝土疲勞壽命預測進行了系統的研究。 -
Study on decision - making of pavement maintenance amp; amp; rehabilitation strategy based on life - cycle cost analysis method
