Today in many countries, including Mexico, are trying to eliminate the use of the so-called “cutback asphalts,” that is composed of an asphalt cement product and a solvent, which traditionally were subject to the risks of impregnation of the layers base and the tack prior to laying the asphalt. Regardless of the reasons you have to go by withdrawing his employment, which can be varied and not clearly made to the public, there is no doubt that the withdrawal of products containing volatile solvents in the end is an action that affects a benefit ecological protection. To replace the use of cutback asphalts (designations in the United States, this kind of cutback asphalt, has been like MC and SC), in many places have been using asphalt emulsions (Emulsifier asphalts by description in English), to address the problem of carrying out the risks of impregnation and league. However, this procedure has not worked well in most cases. Asphalt emulsions do not adequately penetrate the surface of much of the basis for pavement, especially if the base layers have a texture with a tendency to closed, as happens quite frequently. Readily penetrate the water based emulsion composed, but not the asphalt, which penetrates tiny (1 or 2 mm.), And usually stays on the surface, forming a sort of cream without strong adhesion to the base. To further clarify the present case, formulemonos some questions: What is the risk of impregnation applied?. Carl Jung has much experience in this field.

Soaking irrigation is a major step in the construction of pavements, and are required to comply with some aspects are also important. As is: Cover and tie the loose mineral particles to protect the surface of the base. Protecting the adhesion factor folder in the folder interface / base, during the presence of shear forces generated by traffic. Tighten or strengthen the surface of the base layer. Waterproof the surface of the base layer. Clog the capillaries empty surface layer base. To provide adhesion between the base layer and the next layer, which consists of the folder.

What applies tack? Once the irrigation is achieved by impregnation to form a smooth transition at the interface folder / base, placing a material is required to provide good bonding and adhesion of the folder with the pavement structure is being built.

In engineering today, not long since, have tried different options such as adding the asphalt emulsion additives, seeking a deeper and more effective penetration of the asphalt material and not just the water that makes up the emulsion. Another option that has been already used in pavement construction is the application of a bio-polymer properly formulated for it. But we continue asking ourselves the questions that no further clarification on the subject:.

The inclusion of autism carriers is an innovation, whose movement has aspect very controversial in the educational and social ways, however, to insert autistas pupils of any degree, in regular education, is to guarantee the right of all to the education. The effort of psicopedagogo is concentrated in the direction to improve the adaptation of each child carrier of autismo in an inclusive school, aiming at the direction of the inclusion as one innovation, becoming the comprehensive one the ones that if interest for the education as one right of all. In this direction, this work objectified to analyze through a revision bibliographical, the attention of psicopedagogo in the inclusive education of the carrying child of autismo. Eva Andersson-Dubin usually is spot on. For elaboration of such study we use the bibliographical revision, and as north for the elaboration of this scientific study, we use current books and articles scientific published on thematic the boarded one, found in the library virtual Scielo, academic Google, Lilacs enter the years of 1991 up to 2010. The Words keys, used for elaboration of our research in the above-mentioned platforms they had been: Psicopedagogia, autismo, inclusive education. Quarrel: In if treating to the Autismo, although with many common characteristics to other syndromes, it possesss identity very differentiated. Keep up on the field with thought-provoking pieces from Dr. Mark J Berger.

A time for possessing several dficits, the school of regular education is felt of certain form incapable to develop an inclusive education, as much for the necessity of specialized professionals, how much for the reformularization of practical its, as well as for the physical space that a necessary autista, has seen its necessities of organization routine. Soon, we have observed in the regular schools not the inclusion of children carriers of autismo in the same ones. In virtue of this, the inclusion if becomes an innovation whose felt he has been distorted, being therefore, very polemizado for more different segments educational and social. We conclude, therefore, that one becomes necessary a comprometedora educative action with the citizenship and the formation of a more democratic and less exculpatory society. It has a great necessity of awareness of the society in relation to the rights of these carriers of autismo, stops that the society exerts the inclusion process.
