Simulation of asphalt mixtures made by different compaction methods

CRC Press eBooks (2018)

P. Liu Hongmei Xu Dahui Wang Chonghui Wang Christian Schulze

The compaction of an asphalt mixture is greatly important for ensuring durable pavement performance. In the past decades, laboratory compaction methods have been widely used to produce the test specimens, which undergo testing to infer the behaviour of asphalt pavements in the field. To ensure the consistency of samples both on the laboratory scale and from the field, a new laboratory compaction device (Aachen compactor) has been developed. Specimens manufactured by different compaction methods including field compaction, Aachen compaction and Marshall compaction were comprehensively compared and evaluated in this research using experimental tests, digital image processing techniques and the finite element method. The Aachen compactor specimens tend to show a better correlation with field samples than Marshall specimens. Therefore, the Aachen compactor is a feasible alternative for manufacturing asphalt specimens in the laboratory and thus can be used to better simulate the mechanical properties of asphalt mixtures in the field.

Blends of polyester having amino sulfonic acid moieties with poly(vinyl alcohol) and their metal complex formation

Journal of Polymer Science Part A Polymer Chemistry (1997)

Chonghui Wang Toshio Takayama Shigeo Nakamura

Polyester having amino sulfonic acid moieties (TBES) was prepared by a liquid/solid biphase polycondensation of terephthaloyl chloride (TPC) and N,N-bis(2-hydroxyethyl)-2-aminoethanesulfonic acid (BES) in trimethyl phosphate (TMP) using triethylamine (TEA) as an acid acceptor. Blends of TBES with PVA and their metal complexes with Ni2+ and Co2+ ions were prepared. A strong interaction was observed between TBES and PVA. An electric conductivity of 10−6 S cm−1 was attained for the blend films containing about 5 wt % water. A coordination structure with two chelate rings is proposed for the metal complex with Ni2+ and Co2+ ions when the molar ratio of amino sulfonic acid groups in TBES to metal ions is larger than 2. Polymer blends complexed with Ni2+ or Co2+ ions result in semi-interpenetrating polymer networks from chelate formation. © 1997 John Wiley & Sons, Inc. J Polym Sci A: Polym Chem 35: 3561–3569, 1997

[Side branch occlusion rate at sites of overlapping sirolimus- or paclitaxel-eluting stents for treating long coronary lesions].

Hongzhi Xie Quan Fang Shuyang Zhang Zhujun Shen Yong Zeng

To compare side branch occlusion rate at sites of overlapping sirolimus- or paclitaxel-eluting stents in treating long coronary lesions.We retrospectively reviewed the PCI CD and medical records of PCI 141 patients with at least one stent overlapping for long coronary lesion in our institute from January 2004 to October 2007. The side branches occlusion was documented and analyzed.The study population were consisted of 141 patients that there were 115 man, and 26 women, who got 297 stents. There were 154 side branch vessels been observed. Side branch occlusion rate was 24.6% in Cypher group and 31.6% in TAXUS (P > 0.05), side branch TIMI flow decrease rate on overlapping region was 26.3% in Cypher group and 68.4% in TAXUS group (P > 0.05). A logistic regression model analysis show that the significant risk factors for side branch occlusion is the diameter and ostial occlusion of side branch.Side branch occlusion rate and TIMI flow decrease rate were similar on overlapping region in patients treated with Cypher or TAXUS stents for long coronary lesions. The significant predictors for side branch TIMI flow decrease are the diameter and ostial occlusion of side branch.

Feasibility analysis of bio-binder as non-petroleum alternative for bituminous materials

Materials Research Express (2020)

Quan Liu Chonghui Wang Zepeng Fan Shuang Shi Zeyu Zhang

This study discussed the feasibility of bio binders derived from swine manure as the alternative of bitumen. The bio-oil was converted from swine manure via the fast pyrolysis technology. Subsequently, the bio-oil upgraded to bio binders through a preheating treatment. In terms of the lack of studies regarding the compatibility of bitumen and bio binders, this study respectively investigated the blends of bitumen and bio binders from chemical and mechanical perspectives. Mainly, the chemical characterization consisted of extensive measurements using the Thermo-Gravimetric Analysis (TGA), the Differential Scanning Calorimeter (DSC) and, the Fourier Transform Infrared Spectroscopy (FTIR). As for the mechanical performance, the blends of bitumen and bio binders with a content of 5% and 10% by mass were firstly produced and then subjected to the Dynamic Shear Rheometer (DSR) test. Results indicated that the addition of bio binders could enhance the low-temperature performance of the bitumen to some extent. At the low or medium temperature, the blends showed favorable thermal stability. However, the incompatibility issue is noticeable at high temperatures, especially during the mixing and compaction process in practice.

Comparison of Mechanical Responses of Asphalt Mixtures under Uniform and Non-Uniform Loads Using Microscale Finite Element Simulation

Materials (2019)

Guoyang Lu Chonghui Wang Pengfei Liu Stefan Pyrek Markus Oeser

Continuously increasing traffic volumes necessitate accurate design methods to ensure the optimal service life and efficient use of raw materials. Numerical simulations commonly pursue a simplified approach with homogeneous pavement materials and homogeneous loading. Neither the pavement geometry nor the loading is homogeneous in reality. In this study, the mechanical response of the asphalt mixtures due to homogeneous loads is compared with their mechanical response to inhomogeneous loads. A 3D finite element model was reconstructed with the aid of X-ray computed tomography. Sections of a real tire's pressure distribution were used for the inhomogeneous loads. The evaluation of the material response analyzes the stress distribution within the samples. An inhomogeneous load evokes an increased proportion of high stresses within the sample in every case, particularly at low temperatures. When comparing the two types of loads, the average stresses on the interior (tension and compression) exhibit significant differences. The magnitude of the discrepancies shows that this approach yields results that differ significantly from the common practice of using homogeneous models and can be used to improve pavement design.

We describe a case of bilateral thyroid carcinoma in a 48-year-old woman. She was admitted to our hospital as a case of cervical nodular goiter. Multifocality of the thyroid nodules were evaluated by preoperative ultrasonography. The patient received bilateral thyroid lobe total resection and bilateral IV lymph node dissection. Medullary thyroid cancer was confirmed by intraoperative frozen pathology in the right lobe of thyroid gland and papillary thyroid microcarcinoma in the left lobe of thyroid gland. No tumor recurrence and metastasis were found after 3-months follow-up.
