Testing methods for benkelman beam pavement deflectometer 貝克曼梁路面彎沉儀試驗(yàn)方法
Technical requirement for benkelman beam pavement deflectometer 貝克曼梁路面彎沉儀技術(shù)要求
The presence of falling weight deflectometer meets this need 落錘式彎沉儀的出現(xiàn)適應(yīng)了這一需求。
Evaluate road base construction quality using falling weight deflectometer 使用落錘式彎沉儀評(píng)價(jià)基層施工質(zhì)量
Evaluating base course uniformity using falling weight deflectometer 使用落錘式彎沉儀評(píng)價(jià)基層施工質(zhì)量均勻性
The falling weight deflectometer ( fwd ) is used to evaluate the effectiveness of the impact compactor 摘要將落錘式彎沉儀( fwd )成功地用于路基沖擊壓實(shí)效果的檢驗(yàn)。
In the paper , we first have introduced simply the falling weight deflectometer test system for the road ; we have discussed the requirement of property and standard of technology for the data collecting and controlling system 論文首先概述了落錘式彎沉儀路面測試系統(tǒng);描述了其數(shù)據(jù)采集控制器的性能要求和技術(shù)指標(biāo);依據(jù)實(shí)用性、可靠性及系統(tǒng)可擴(kuò)展性原則,提出了一種基于嵌入式技術(shù)的硬件和軟件實(shí)施方案。
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)行檢測方法存在的問題,通過現(xiàn)場不同方法的對比檢測,建立了激光平整度測試車、探地雷達(dá)測試系統(tǒng)、摩擦系數(shù)測試車和落錘式彎沉儀( fwd )等新型檢測方法和規(guī)范測試方法間的相關(guān)關(guān)系,從而提出新型檢測的質(zhì)量控制標(biāo)準(zhǔn)。
