Study on pavement performance of hma mix ' s aggregate gradations near restricted zone 瀝青混合料禁區路用性能研究
Firstly , aggregate particles of various sizes were generated for a given aggregate gradation curve and aggregate area fraction 首先,按照骨料級配曲線和面積百分比,生成各種尺寸的骨料顆粒。
Extraction tests were conducted on asphalt concrete specimens sampled from field roads . asphalt concrete and aggregate gradation were compared to design and acceptance specifications 對實際路面取樣進行了抽提試驗并與規范進行了比較分析。
The paper has put forward and testified four utilizable aggregate gradation . because the method of preparing samples has certain effect on material property parameter of mixture , the paper recommend static preparing method be adopted 試件成型方法對大孔隙水泥穩定碎石混合料的材料性能參數有一定的影響,本文推薦室內試件成型方法為靜壓成型。
Research results indicate that aggregate gradation extracted from field samples are out of gradation bounds specified in the design file , which can be one of the contributing factors in the development of pavement distress , especially premature failure 研究結果表面瀝青混合料的級配超出設計范圍可能是影響路面長期性能并呈現早期破壞的原因之一。
The aggregates gradation of lime - fly ash stabilized aggregates which is recommended by design specification of highway asphalt pavement is finer , so that the anti - bnishing performance and the anti - crack performance of lime - fly ash stabilized aggregates are worse 《公路瀝青路面設計規范》中推薦的二灰穩定碎石基層的集料級配偏細,導致其抗沖刷性能和抗裂性能較差。
Based on uniaxial penetrating test , the effects of aggregate gradation , aggregate physical properties , asphalt binder properties , asphalt content , air void and homogeneity on shear resistance of asphalt mixture were investigated directly at 60 摘要為了研究瀝青混合料抗剪強度的影響因素,基于單軸貫入試驗,在溫度為60時,直接對集料級配、集料性質、瀝青性質、含油量、空隙率以及均勻對瀝青混合料抗剪強度的影響進行研究。
Lots of laboratory test has been carried out to study the design method of atpb , the analysis of resulting data has been described to determine the effects of aggregate gradation and asphalt content on the permeability and the resilient modulus of atpb materials 在參考國外研究成果的基礎上,通過室內試驗的不斷調整,最后確定出三種符合各項目標性質指標的級配,同時總結出對于大空隙開級配瀝青混和料瀝青最佳用量的確定方法。
This thesis for the first time bases its analysis on the maintenance characteristics and repair mechanisms for crack filling and pothole repair in asphalt roads . it analyzes the properties of the aggregate and the bituminous binder in patching materials , and further analyzes the compatibilities of the aggregate and the bituminous binder , patching materials and old pavement materials . furthermore , it determines the grading types , the mineral aggregate gradations , the application rate of asphalt , the principle of selecting component materials and the air void 本文首次依據瀝青路面裂縫填封和坑槽修補的維修特性和修補機理,全面分析了修補材料中集料與瀝青結合料應具備的性能要求,并對集料與瀝青結合料、修補材料與原有路面材料的相容性進行了深入的分析,同時分析確定了修補材料的級配類型、礦料級配、瀝青用量范圍、組成材料的選用原則及空隙率等。
The specific structure endues the sbs with the superior properties and the sbs is the most useful modifier . according to technical specifications for construction of highway asphalt pavement , climate and design , the shell - 90 asphalt is modified by sbs and conclusions are followed : ( 1 ) the aggregate gradation of mixture is determined by marshall stability experiments . the most suitable content of asphalt is also determined as 4 . 9 % for general asphalt and 4 . 8 % for modified asphalt 本論文按照《瀝青路面施工技術規范》的要求,結合蘇州的氣候特點和實際設計、施工要求,對殼牌90 #瀝青進行了sbs改性研究,得到如下結論: ( 1 )利用馬歇爾法確定了混合料的級配,并確定了最佳瀝青用量,對基質瀝青的最佳用量為4 . 9 % ,改性瀝青的最佳用量為4 . 8 % 。
