Experience and procedures for dimension of flexible road construction structures is a complex process. Therefore, several dimension methods are used: ASHTO formed in 1959 in the state of Illinois, USA, Federal Association for Public Roads and Transport AASHTO 2004, methods of the Institutes for asphalt formed in 1955 in England ASSHO and WASHO, method of the SHELL group and method of (FAA) Federal Aviation Administration USA. Methods for collecting data and accumulating them in an appropriate project include design levels, predictions of damage, unevenness, assessment of characteristics, design reliability, expected costs, dimension, and predicting the behavior of pavement structures. The AASNTO method is based on the results of an experiment made in the state of Illinois in 1959 and 1960, and the first guideline was published in 1961 since then, updates have been published regularly to track down the latest findings in the area of pavement structures. There are also computer programs designed for using this method, one of which is "FLEXPAVE". The ASSOA and WASHO method appeared in 1955 in England, it is implemented by the asphalt institute. In the upcoming years this method was upgraded in collaboration with the US engineering corps, the US government agencies and the most famous numerical procedures for the time, as well as computer programs "DAMA" "BISAR "And" CHEVRON ". This software enables the monitoring of monthly changes in condition and destruction by entering the corresponding input data. Through the SHELL group method, the pavement structure is viewed as a linear elastic multi-layer system whose layers have their own characteristics that are expressed through the modulus of elasticity Poisson's coefficient. The traffic is expressed through an ESA - an equivalent standard axis, which acts vertically and it is equally distributed over one or more circular surfaces. Through the (FAA) method, the Federal Aviation Administration in the United States has issued a manual for the dimension of pavement structures depending on the mass of the plane, based on its own classification of the ground, the characteristics of the materials that are part of the pavement structure, the loading of the main aircraft, repetition of the load and the frost effect. Based on these parameters, the thickness of the pavement structure is determined. Today, there is software based on the finite element principles of FEAFAA, FEDFAA, BAKFAA return program, and a program for determining the ACN number COMFAA

The methodology for calculating pavements used in the United States is discussed in this article. The article contains the principles of pavement design outlined in the manual “P. Design of New and Reconstructed Flexible Pavements. Part 3”, which are used by designers not only in the United States, but also in many countries around the world. Differences in approaches to pavement design in the Russian Federation and the United States are shown. It is marked that in difference from Russia, where requirements documents are valid on all territory of the country, in America each state develops its own requirements documentation, however the general principles of designing presented in the above-mentioned manual, remain invariable. In order to compare the pavement structures used in Russia and the USA the author has given examples of constructions developed on the basis of the US guidelines and has shown the main differences of these constructions from those which are traditionally applied in our road construction. In addition, the author draws attention to the fact that in contrast to Russia in the U.S. roads usually have a non-rigid type of pavement, which significantly increases their strength and durability

Colorado manages water using an administrative structure that is unique among the United States following the doctrine of prior appropriation: Water rights are adjudicated not by the State Engineer, but by Water Courts – separate from and operating in parallel to the criminal and civil courts – established specifically for this purpose. Fundamental to this system is the notion that water rights are property, with consequent protections under the US Constitution, but with the significant constraint that changes in water rights must not injure other water rights, either more senior or more junior. Population growth and climate change will certainly trigger changes in water administration, to be guided by the recent Colorado Water Plan. To provide the foundation necessary to appreciate these changes, this paper reviews the history of Colorado water administration and summarizes the complementary roles of the Water Courts and the State Engineer. Understanding water administration in Colorado depends on a firm grasp on how these two branches of state government formulate and implement water policy.

The American War in Afghanistan is a full history of the war in Afghanistan between 2001 and 2020. It covers political, cultural, strategic, and tactical aspects of the war and details the actions and decision-making of the United States, Afghan government, and Taliban. The work follows a narrative format to go through the 2001 US invasion, the state-building of 2002–2005, the Taliban offensive of 2006, the US surge of 2009–2011, the subsequent drawdown, and the peace talks of 2019–2020. The focus is on the overarching questions of the war: Why did the United States fail? What opportunities existed to reach a better outcome? Why did the United States not withdraw from the war?

Introduction: the election law of the US states to date remains insufficiently studied not only in Russia but also abroad. This is due to the fact that the legal regulation of the electoral process in America is attributed to the powers of the states or municipalities, depending on the legal doctrine applied by the state – Cooley Doctrine or Dillon Rule, which objectively imposes a limit on its study and generalization. The purpose of the study is to acquaint a wide range of scientific community with the latest research in the field of the US election law in regard to the first in the domestic law full description of the organizers of elections and referendums at the state and municipal levels in the United States. The author reviews a wide range of regional and local legislation with references to the constitutional, legal and regulatory acts of the US States. The paper is part of a series that explores all fifty subjects of the American Federation and the District of Columbia. Procedure and methods of research: the author analyzes the constitutional and electoral legislation of the United States at the level of Montana at the beginning of 2019. The methodology of the study was the comparative law, formal-legal, formal-dogmatic, specific-sociological, empirical, dialectical, analytical methods, the systematic approach. Results: the information about the organizers of elections and referendums in Montana, which was not previously covered in the Russian scientific literature, is introduced into scientific circulation. The interpretations of certain provisions of the law and legal consciousness of the U.S election law and law enforcement practice are given. The gaps of the legislation requiring additional research are surfaced. The theoretical and practical significance lies in the generalization of both the established and the latest legal sources (constitutions, organic laws, federal laws, charters, by-laws and regulations) of the United States and the subject of the American Federation and the development of proposals for the enrichment of the Russian science and the formation of objective understanding of the processes taking place in the United States in the field of constitutional, electoral law and the state-building. Conclusions: for a systematic and comparative legal analysis the author proposed the review of the legislation on the organizers of elections and referendums of Montana, revealing the existing contradictions, from the point of view of the Russian researcher, which allows considering the full range of elements of the electoral legislation of Montana from a new angle, seeing new legal structures, previously unknown to the domestic statesmen and law enforcers.

The Impact

As part of its “War on Terror”, the United States (US) provided immense sums of money and advanced equipment to Afghan warlords in order to defeat and dismantle the Taliban and al-Qaeda in Afghanistan. Nearly two decades after the 2001 US-led intervention in Afghanistan that toppled the Taliban regime, the US continues supporting the warlords in various ways. As the intervention was also aimed at establishing a functioning state and reconstruction of the war-torn country, the US needed the support of local warlords to achieve its goals. However, over time, warlords and warlordism became a major challenge to the postTaliban state-building project and in many ways undermined the overall security and the state monopoly on violence. These warlords, who had been mostly expelled and defeated by the Taliban regime, returned under the aegis of the B52 bombers, recaptured parts of the country and reestablished their fiefdoms with US support and resources. They not only resist giving up the power and prestige they have accumulated over the past few years, but also hamper the effort to improve governance and enact necessary reforms in the country. In addition, many of them run their private militias and have been accused of serious human rights abuses as well as drug trafficking, arms smuggling, illegal mining and extortion in the areas under their control or influence. In many ways, they challenge the government authority and have become a major hurdle to the country’s emerging from lawlessness and anarchy. This paper explores the emergence and reemergence of warlords in Afghanistan as well as the evolution of chaos and anarchy in the country, especially after the US-led intervention of late 2001. It also analyzes the impact of the post-9/11 US support to Afghan warlords and its negative consequences for the overall stability and the US-led state-building process in Afghanistan.

The United States' diplomatic security apparatus that operates today from Washington DC to Iraq and Afghanistan is uniquely massive. It is incomparable in its size, budget, degree of institutionalization, and level of sophistication when set against both other nations as well as its own humble origins in WWI. To understand why this is so, the first half of this chapter historically maps and causally explains how, and why, US diplomatic security has been transformed over the course of its modern hundred-year history. The second half provides an empirically rich study of the various roles and functions of the State Department's Bureau of Diplomatic Security and the US military units that protect the US diplomatic mission.

AbstractIntroduction:In 2009, the Institute of Medicine published guidelines for implementation of Crisis Standards of Care (CSC) at the state level in the United States (US). Based in part on the then concern for H1N1 pandemic, there was a recognized need for additional planning at the state level to maintain health system preparedness and conventional care standards when available resources become scarce. Despite the availability of this framework, in the years since and despite repeated large-scale domestic events, implementation remains mixed.Problem:Coronavirus disease 2019 (COVID-19) rejuvenates concern for how health systems can maintain quality care when faced with unrelenting burden. This study seeks to outline which states in the US have developed CSC and which areas of care have thus far been addressed.Methods:An online search was conducted for all 50 states in 2015 and again in 2020. For states without CSC plans online, state officials were contacted by email and phone. Public protocols were reviewed to assess for operational implementation capabilities, specifically highlighting guidance on ventilator use, burn management, sequential organ failure assessment (SOFA) score, pediatric standards, and reliance on influenza planning.Results:Thirty-six states in the US were actively developing (17) or had already developed (19) official CSC guidance. Fourteen states had no publicly acknowledged effort. Eleven of the 17 public plans had updated within five years, with a majority addressing ventilator usage (16/17), influenza planning (14/17), and pediatric care (15/17), but substantially fewer addressing care for burn patients (9/17).Conclusion:Many states lacked publicly available guidance on maintaining standards of care during disasters, and many states with specific care guidelines had not sufficiently addressed the full spectrum of hazard to which their health care systems remain vulnerable.

Abstract There are persisting geographic and racial disparities in life expectancy (LE) across the United States (US). We used 5% Medicare Claims data (2000-2017) to investigate how disease incidence and survival contribute to such disparities. Disease-specific hazard ratios (HRs) were calculated for Medicare beneficiaries living in the US states with the lowest LE (the states with the highest LE were used as a reference group), in gender- and race-/ethnicity-specific populations. Analysis of incidence showed that the greatest contribution to between-the-state disparities in LE was due to higher incidence (HRs≥1.30) of atherosclerosis, heart failure, influenza/pneumonia, Alzheimer’s disease, and lung cancer among older adults living in the states with the lowest LE. The list of diseases that contributed most to LE through the differences in their survival substantially differed from the above listed diseases: namely, diabetes, chronic ischemic heart disease, and cerebrovascular disease had HRs≥1.28 for their respective survival rates, with the highest HRs for lung cancer (HR=1.37, in females) and prostate cancer (HR=1.30). Respective race-/ethnicity-specific patterns of incidence and survival HRs were investigated and diseases contributed most to racial disparities in LE were identified. Study showed that when planning the strategies targeting between-the-state differences in LE in the US, it is important to address both 1) primary and secondary prevention for diseases demonstrating substantial differences in contributions of incidence, and 2) treatment choice, adherence to treatment, and comorbidities for diseases contributing to LE disparities predominantly through the differences in survival. Such strategies can be disease-, race-/ethnicity-, and geographic area-specific.
