  1. Assure the minimum hortative wavelength by the international roughness index

    由國際平整度指數確定路面激勵最小波長
  2. The scattering intensity of rough surface is computed, while the roughness, polarization, observation station and the refractive index are different, and the wavelength of incident light is 0. 48 m. the results indicates the rougher the rough surface is, the less the coherent scattering is ; the influence of the smaller refrective index is more than larger one by the polarization

    計算了入射光波長為0 . 48 m時，不同粗糙度，偏振態，散射角以及不同折射率的粗糙面散射強度，結果表明，粗糙面越粗糙，相干散射越小，非相干散射越強;偏振態對折射率大的粗糙介質面影響較小，對折射率較小的介質面的影響較大。
  3. Standard practice for computing international roughness index of roads from longitudinal profile measurements

    從縱剖面測量計算道路國際粗糙度指數的標準操作規程
  4. In the light of its special property being not easy to gain strength, through mechanics researches on different methods to stabilize this kind of low _ liquid _ limit silty soil as subbase material, evaluated both technically and economically, we have got a cement lime stabilization plan to meet the index requirements for non _ side _ limit strength of compression of subbase of class2 road stipulated in the specification ; by means of improving the workmanship, thickening the loose layer of soil, adding soil on covering weave fabric before compaction, such problems can be solved as very poor compaction, loose surface during compaction, roughness and unevenness, coats of layer and shear damages

    本文針對黃河沖積而成的低液限粉土其粘粒含量極低、土的不均勻系數很小、膠體活性差的工程特性，通過採用不同方法穩定該類土作底基層材料的力學性能研究，從技術、經濟角度綜合評價，得到滿足規范抗壓強度指標要求的水泥石灰穩定方案。通過對原材料、試驗配合比設計、施工、等方面進行優化，從而顯著減輕了基層的早期及長期縮裂程度，從而提高了路面的耐久性。
  5. Experiment results prove that this algorithm is a practical and effective method, with which the ideal cross - section curve can be acquired. the result is coincidence to the standard iri ( the international roughness index ) and meets the necessity

    實驗結論：基於陣列信號處理和小波降噪的演算法應用於路面平整度檢測可以得到較理想的斷面曲線，換算國際平整度指標iri與標定較吻合，符合處理要求。
  6. This paper introduces some models of pavement operational performance ( including pavement structural remaining life, pavement condition index pci skid resistance index and international roughness index iri ) in term of application of apms

    根據國內外常用的機場道面性能模型研究狀況和道面管理系統的特點，介紹了道面結構剩餘使用壽命、道面狀況指數pci 、道面防滑性系數?和道面國際平整度指數iri常用的衰變模型。
