Evaluation and Influencing Factors on Particle Agglomeration in RAP

引用

Journal of Wuhan University of Technology(Materials Science) 2024年第1期39卷 60-68页

作者：唐伟李宁 ZHUANG yuan ZHAN He yu xin WU Wenxiu ding Gongying College of Civil and Transportation Engineering Hohai UniversityNanjing 210098China Jiangsu Expressway Engineering Maintenance Technology Center Nanjing 211106China Jinhua Highway and Transportation Management Center Jinhua 321000China

Asphalt extraction test and scanning electron microscopy(SEM) were used for analysis of agglomerations of reclaimed asphalt pavement(RAP) particles. In order to quantify the agglomeration degree of RAP, the fineness modulus ratio(FMR) and the percentage loss index(PLI) were proposed. In addition, grey correlation analysis was conducted to discuss the relationship between particle agglomerations and RAP size,asphalt content(AC), and surface area. Two indexes indicate that the agglomeration degree increases in general as the RAP size reduces. This can be attributed to that particles are prone to agglomeration in the case of higher AC. Based on the SEM images and the material composition of RAP, the particle agglomeration in RAP can be classified into weak agglomeration and strong agglomeration. Grey correlation analysis shows that AC is the crucial factor affecting the agglomeration degree and RAP variability. In order to produce consistent and stable reclaimed mixtures, disposal measures of RAP are suggested to lower the AC of RAP.

引用

Chinese Medical Journal 2015年第20期128卷 2726-2730页

作者： Fang Wang Lin-Qing Zhao Ru-Nan Zhu Jie Deng yu Sun Ya-xin ding Run Tian yuan Qian Laboratory of Virology Beijing Key Laboratory of Etiology of Viral Diseases Capital Institute of Pediatrics Beijing 100020 China

Background： Although human parainfluenza virus （HPIV） has been determined as an important viral cause of acute respiratory infections （ARIs） in infants and young children, data on long-term investigation are still lacking to disclose the infection pattern of HPIV in China. Methods： Nasopharyngeal aspirates were collected from 25,773 hospitalized pediatric patients with ARIs from January 2004 through December 2012 for respiratory virus screen by direct immuno-fluorescence assay. Results： Out of these specimens, 1675 （6.50%, 1675/25,773） showed HPIV positive, including 261 （1.01%, 261/25,773） for HPIVI, 28 （0.11%, 28/25,773） for HPIV2, and 1388 （5.39%, 1388/25373） for HPIV3, 2 of the samples were positive for both HPIV1 and HPIV3, and 36 were co-detected with other viruses. The positive rates of HPIVs were higher in those younger than 3 years old. HPIV3 was detected from all age groups, predominantly from patients under 3 years of age, and the highest frequency was found in those 6 months to 1-year old （352/4077, 8.63%）. HPlV3 was the dominant type in each of the years detected between May and July. HPIV1 showed a peak in every odd year, mainly in August or September. HPIV was detected most frequently from patients with upper respiratory infection （12.49%, 157/1257）, followed by bronchitis （ 11.13%, 176/2479）, asthma （9.31%, 43/462）, bronchiolitis （5.91%, 150/2536）, pneumonia （6.06%, 1034/17,068）, and those with underlying diseases （1.0%, 15/1506）. HPIV3 is the dominant type in these six disease groups referred above, especially in the asthma group. Conclusions： HPIV is one of the important viral causes of ARIs in infants and young children in Beijing based on the data from the hospitalized children covering a 9-year term. HPIV3 is the predominant type in all these years and in most of the disease groups. HPIVs with different types show different seasonality.
