This article begins pointing out the American origin of classical Aena asphalt mixtures on FAA AC-5370-10 D "Standards for Specifying Construction of Airports" item P-401 "Hot Mix Asphalt". Gradations of Spanish and American mixtures, show an almost complete superposition when drawn together. Then, new designations of this mixtures are presented according EN-13 108 European Norm: 3 of AC (Asphalt Concrete) type defined on Part 1 of this Norm; 1 of BBTM (Discontinuous Graded Mixture for Very Thin Layers) type defines on Part 2; and 1 of SMA (Stone Mastic Asphalt) type defined on Part 5, Offering an overview of their new gradations and most special features. A note about requested surface texture and skid resistance of airport pavements closes the article. Source


This article introduces the resistant and surface characteristics of a pavement to be published by airport authorities when introducing a new paved surface or a big intervened one. And also load conditions of airplanes related to declared PCN. Shows the way to communicate and understand the declared PCN of a pavement. Presents PCN measured on different zones and times in Barcelona Airport. Analyses possible operative affections of lowest measured values, concluding they are inexistent. Marks reasons to demand a surface texture; defines typical measuring standard test and levels prescribed by FAA in new pavements, in normal service, and thresholds advertising to regenerate it before one year and before two months. A short consideration is made upon wheels movement on landing touch-down, running and braking. And points out measures results kept on three campaigns on both runways. Related to skid resistance coefficient, presents minimum values prescribed by FAA depending on the used device and its speed of measurement. Factors governing it are presented. Considerations about differentiating two zones of pavement in every runway are made. Finally, evolution of skid resistance on both runways is analysed relating to operative conditions. Source


The article describes the initial composition of the airfield of Barcelona Airport, the improving works approved on his Master Plan, and the evolution of its operational capacity. Presents the used pavements types, and close together, similarities and differences between runways and roads. Analyses performances of flexible and rigid pavements, and marks the use criterion where them better fulfil needed functionality. It presents too airfield new parts built up of every pavement kind. Typical paved zones are presented, attending frequency and intensity of supported loads. Finally, it describes subsoil layers; how a surcharge embankment was built, instrumented and surveyed, and knowledge acquired and applied. Source

In the recent years many problems are emerging due to the aircraft noise on the airport surrounding areas. The solution to this problem is not easy considering that the neighbourhood asks for the reduction of the number of aircraft operations and the airlines ask for a growing demand in the number of operations in the major airports. So the airport and regulatory authorities try to get a solution imposing a fine to the aircraft which its actual trajectory differs from the nominal one more than a lateral deviation. But, which is the value of this deviation?. The current situation is that many operators have to pay a lot of money for exceeding a deviation which has been established without operational criteria. This paper presents the results of a research program which is being carried out by the authors which aims to determine the "delta" deviation to be used for this purpose. In addition it is proposed a customized method per SID and per airport to be used for determining the maximum allowed lateral deviation by which if the aircraft is within it, then none fine will be imposed. The paper will also explain the current criteria used to design and publish the SIDs and will show the results of the performed assessment for determining the deviation of different aircraft families flying the same departure procedure in an airport aiming to define a current deviation value considering operational factors such airfield elevation, temperature, wind, SID design, etc. And last, the method for determining the allowed lateral deviation without any penalty consists in the computation of a set of templates per aircraft family/SID/airport, in such a way that a particular deviation could be compared against the corresponding template. When the trajectory to be assessed is within the selected template limits, it will mean none penalty should be imposed. Source


PMBOK® standards, provided by the Project Management Institute (PMI), are widely accepted in Project Management. On the other hand, Lean Thinking philosophy is based on the strict fulfillment of customer needs, avoiding anything not valuable from the client viewpoint. In the last few years, Lean Thinking philosophy has been applied to construction projects, so as to become a differentiated management system, called "Lean Construction". Moreover, some authors believe that projects with certain level of uncertainty cannot be managed using PMBOK® standards, but have to be managed by the standards provided by the "Lean Construction Institute". Nevertheless, in this article the compatibility of both methods is defended. Specialized literature has been revised in order to compare Project Management and Lean Construction methods. Lean Construction projects results have been analyzed in order to prove that their achievements have been remarkable in terms of predictability of time and cost. Discussion has been done so as to prove the compatibility of Project management and Lean Construction. As a conclusion, the article proposes a model to implement both methods in a systematic and feasible way. Source
