The aging of asphalt pavement gets serious in the course of service due to the large number of vehicles and high pavement temperature. A survey was conducted on urban road’s asphalt pavement in the city of Tianjin. By analyzing the extracted asphalt sample from asphalt pavement built in different years, it shows that asphalt’s softening point and viscosity increase but its penetration and ductility attenuate with the extension of service period. Of which, the ductility changes dramatically with its ductility attenuating fast in the early years of service and the attenuation of ductility tending to slow down later. The vertical difference of aging in different depth of pavement is marked and degree of aging tends to attenuate from the surface to the center.

During the early years of the Civil Wars in England, from February 1642 to July 1643, Puritan parishioners in conjunction with the parliament in London set up approximately 150 divines as weekly preachers, or lecturers, in the city and the provinces. This was an exceptional activity surrounding lectureships including the high number of lecturer appointments made over the relatively brief space of time, especially considering the urgent necessity of making preparations for the looming war and fighting it as well. By examining a range of sources, this article seeks to demonstrate that the Puritan MPs and peers, in cooperation with their supporters from across the country, tactically employed the institutional device of weekly preaching, or lectureships, to neutralize the influence of Anglican clergymen perceived as royalists dissatisfied with the parliamentarian cause, and to bolster Puritan and pro-parliamentarian preaching during the critical years of 1642–1643. If successfully employed, the device of weekly lectureships would have significantly widened the base of support for the parliament during this crucial period when people began to take sides, prepared for war, and fought its first battles. Such a program of lectureships, no doubt, contributed to the increasing polarization of the religious and political climate of the country. More broadly, this study seeks to add to our understanding of an early phase of the conflict that eventually embroiled the entire British Isles in a decade of gruesome internecine warfare.

The article is devoted to the early years of formation of Kharkiv scenography school and to the creative and pedagogical activities of Olexander Khvostenko-Khvostov (1895–1967). It was reported that the bold experiments of this artist, in the field of theatrical design of 1918–1922, made him one of the central figures of Kharkiv avant-garde scene (“Mystery Buff”; “The Army in the City”; “Lilyuli”, etc), strengthening the reputation of an innovator and causing the beginning of pedagogical activity at the Kharkiv Art College in 1921. The theatrical and decorative workshop was opened at the faculty of painting at the Kharkiv Art College in 1922, it was headed by A. Khvostenko-Khvostov. Among the first graduates were such bright alumni as A. Volnenko, P. Suponin, V. Ryftin, A. Bosulaev, B. Chernyshov, and others. Fundamental provisions of the educational program, which A. Khvostenko borrowed from the teaching practice of A. Exter (Kyiv Studio, 1918–1920), reflected the formation idea of future theater artist’s synthetic thinking. It is known that the education program of the Theater and Scenery Workshop of KAC, equally with the Studio of A. Exter, in addition to the subjects common to all students of painting and drawing faculty as special subjects (theatrical scenery, technique and technology of the stage, etc.) included also the history of theater (I. Turkeltaub), material culture, costume, music and literature (A. Beletsky). O. Khvostenko paid special attention to theoretical and practical issues of composition. He introduced the course of fundamentals of directing (V. Vasilko) as a compulsory subject. Much of what the students mastered at the Workshop was tested on the professional stages of Kharkiv theaters. Associated with the Kharkiv Art School for a quarter of a century (1921–1946), O. Khvostenko-Khvostov has not still been included in the pantheon of its outstanding teachers.

<p><strong>Abstract.</strong> Fire insurance maps produced by the American firm the Sanborn Map Company have long served as cartographic guides to understanding the history of urban America. Primarily used by cultural and historical geographers, historians, historic preservationists, and environmental consultants; historians of cartography have little explored the history of this company. While this scholarship has addressed various facets of Sanborn’s history (Ristow, 1968), no scholarly piece has explored the lived experience of being a Sanborn surveyor. This lack of scholarship comes not from any significant oversight but rather from the fact that the contributions of most Sanborn surveyors were anonymous and little recorded on the maps themselves. Moreover, the company itself has done little to save its own history, thus little is known of their individual stories and experiences. The exception to this is perhaps the most famous Sanborn surveyor of all: Daniel Carter Beard.</p><p>Over the course of his nine-decade life, Daniel Carter Beard held several prominent positions including the co-founder of the Boy Scouts of America and the lead illustrator for many of Mark Twain’s novels. However, he got his start as a surveyor for the Sanborn Map Company in the 1870s, just a few years after its founding. His papers, housed at the Manuscript Division of the Library of Congress, includes a variety of ephemera from his time with the Sanborn Map Company.</p><p>Trained in civil engineering, Beard got his start as a surveyor for the Cincinnati (Ohio) Office of Platting Commission, creating the first official plat map for the city. He was hired by Sanborn in 1874 and served as a surveyor until 1878, traveling extensively over the eastern half of the United States, parlaying his skills into creating fire insurance maps for Sanborn. Thus, this paper speaks to two main themes. The first theme traces the route of Beard during his early years with the company across the eastern half of the United States, documenting both the places he visited and the challenges he faced as a Sanborn surveyor. The second theme, interwoven through the paper, is an analysis of the innerworkings of Sanborn’s administrative structure and its relationship with the larger fire insurance market during the 1870s. Altogether, these documents present unique insight into the organization of the Sanborn Map Company and how it produced its maps during the second-half of the 19th century.</p>

As the important part of expressway, the construction technology of asphalt pavement will contribute to the production of greenhouse gases and other volatile organic compounds (VOCs), which has a significant impact on the environment. In order to further analyze the composition, distribution and release of VOCs during asphalt pavement construction, the VOCs emission during paving and rolling were measured through field investigation and sampling. The results show that there are approximately 100 kinds of VOCs substances detected due to the complex organic component of asphalt binder, which is a critical factor to influence the VOCs emission during asphalt pavement construction. During the paving process, the largest VOCs release is 1015.05 ug/m3. With the increase of rolling times, the pavement temperature gradually decrease, and the VOCs emission drops to 266.73 ug/m3. The content of the 10 kinds of substances with the highest concentration accounts for more than 50% of the total VOCs content, in which the proportion of aliphatic hydrocarbons (ALH) and oxygenated hydrocarbon (O-HYD) of the paving process are the highest, while the proportion of aromatic hydrocarbons (ARH) is dominated in the rolling process. The results are vulnerable to the external environment, especially at lower emission level. The relevant research results have certain guiding significance for the control and treatment of harmful gas emission in the construction process of asphalt pavement.

This chapter narrates the early years of postsocialist transformation as Hungarians sought to make remake themselves as new national subjects amid the remains of multiple discredited pasts and failed historical trajectories. It explores how politicians, activists, and public officials initially conceptualized the problem of socialist remains in terms of physical remainders perceived to be emblematic of the former regime. Politicians, activists, and public officials battled to “spring clean” remains of the communist past in order to restore Hungary to the “authentic” course of national history. The chapter also focuses on the debates that resulted in the removal of Budapest's socialist-era statues to a Statue Park Museum on the outskirts of the city. Supporters justified the creation of the park as a democratic solution to the outrage that communist monuments inspired. Yet the removal of these statues was not a response to a crisis of defacements and public dissatisfaction, but an attempt to cover up the fact that little such crisis existed.

Francis Vernon (c. 1637-77) is not a particularly well-known figure in the history of British architecture, but perhaps he should be. In 1675 he became one of the first English people to have set foot in Athens and, the following year, published what was undisputedly the first account in the English language of the city and its architecture. Vernon was a member of the recently founded Royal Society and one of a group of English and French travellers who journeyed through central Greece and Turkey in the 1670s. He was murdered in Isfahan in early 1677. Vernon's account of the time he spent in Athens was published in the Society's journal, thePhilosophical Transactions, in 1676, and it included brief but illuminating descriptions of the Erechtheion, the Temple of Hephaestus and the Parthenon, the latter written over ten years before the bombing of the temple by a Venetian army in 1687. TheTransactionsoften contained both travel writing and antiquarian material and, in this respect, Vernon's account was typical of the journal's somewhat eclectic content in its early years. Significantly, Vernon's publication predated more famous accounts of Greece from the period, such as those written by his travelling companions Jacob Spon (who released hisVoyage d'ltalie, de Dalamatie, de Grèce et du Levantin France in 1678) and George Wheler, whoseA journey into Greecewas published in 1682. Unlike Vernon, both Spon and Wheler survived their journeys. The only European publication on Athens that preceded Vernon's was a French text of 1675 that would prove to be a fabrication. As this article will demonstrate, Vernon's initial exposure of this fabrication was one of the reasons why his account of the city became so important in English intellectual culture at the time.

Johannes Martin Bijvoet* was born on 23 January 1892 in Amsterdam. His father, Willem Frederik Bijvoet, owned a dye factory. His mother was Barendina Margaretha Ruefer. He was the third of four sons in a harmonious family. His eldest brother, Willem Frederik, became a well known gynaecologist; his second brother, Bernard, became a famous architect; and his youngest brother, Frederik, succeeded his father in the management of the dye factory. The family lived in a traditional old house on the banks of one of his beloved Amsterdam’s many canals, the Binnenkant. In addition, they owned a small summer house in the dunes near IJmuiden, which was, in Bijvoet’s own words, ‘unequalled for romantic beauty, but in later years wiped out by the extension of a blast furnace site, so that even at an early age I met with the reverse of industrial blessing’. From 1897 to 1903 young Bijvoet went to the primary school ‘Zeemanshoop’ (sailor’s hope) at the Prins Hendrikkade, and from 1903 to 1908 he attended secondary school, the ‘Eerste vijfjarige HBS’ (literally: first five-year higher civil school) on the Keizersgracht. From these early years, spent in the old centre of the city, dated his lifelong attachment to Amsterdam .
