In this paper , it also analyses the disadvantages of methods in present pavement specification . by means of parallel field test experimentation , and gives the correlativities between test methods of specification and new pattern test methods , such as road surface profiler , ground penetrate rada test system , friction test vehicle , falling weight deflectometer . based on these correlativities , their test and quality control standards are formed 本文還分析了路面現(xiàn)行檢測(cè)方法存在的問題,通過現(xiàn)場(chǎng)不同方法的對(duì)比檢測(cè),建立了激光平整度測(cè)試車、探地雷達(dá)測(cè)試系統(tǒng)、摩擦系數(shù)測(cè)試車和落錘式彎沉儀( fwd )等新型檢測(cè)方法和規(guī)范測(cè)試方法間的相關(guān)關(guān)系,從而提出新型檢測(cè)的質(zhì)量控制標(biāo)準(zhǔn)。
百科解釋
A falling weight deflectometer, FWD, is a testing device used by civil engineers to evaluate the physical properties of pavement. FWD data is primarily used to estimate pavement structural capacity for 1) overlay design and 2) to determine if a pavement is being overloaded.
