An adventure with Practical Period in Adraskan

A

s known, one of the most important matters in development of a country depends to its main transpirations ways (such as land road, Railways, Air ways and sea ways), which the Land transportations ways (Roads), Are the most especial and inexpensive and also the important part of these types.

        As  all we know ,we have only two types of these links is available for us ,and unfortunately  the Air ways links are not so suitable and safe for marketing use or for traveling. So the rest type is Land  roads that we can use that for development and usual use in dairy works . And also we know that ,this type of  transportation is damaged due to several war years. So as an engineer  the only minimum  thing that we can do for accelerating the development and after that going to independence economics is to build or to rehabilitate the  contacting Roads and  Highways.

         And for doing well this duty, it’s needed to increasing our know ledges  about building of new roads and or  rehabilitation of the existing roads .but for our new government and by  the preliminary  possibilities we just can think about the rehabilitations of existing Road due to the high cost of  new projects .

         And there fore  I decided to earn some knowledge and experience about  Road extension, and rehabilitation of the existing Roads .

         So the best way was to spend my practice period  in a project that has relation to Road construction ,which was Louis Berger Group Inc , which is a construction company and also  rebuild the Kandahar -Kabul  in the past and is Working on Herat -Kandahar High way( for more information about this company please click the link Here ).

         And as I want, I could take a train course (with  very hard working  days) in central laboratory  of this company in Afghanistan. And I can strongly claim which it is the only complete and good laboratory inside Afghanistan, (for seeing pictures click here).

         The general description of the train period will be attached by this preface, but for some discussion about laboratory itself, I must say that in common the works in laboratory is divided by two parts:  Sampling, and testing, which both of these have several branches, each of the mentioned procedures have determined specification and minimum requirement which generally is explained in contracts between employee and client.

          The general requirements and specification of tests and their procedure and applications is referenced to ((AASHTO)) or ((ASTM)) reference manual, which are the most common and accurate engineering manuals.

         In next pages you can find the general procedure of some important tests which commonly had tested in laboratory, somewhere, available pictures or data bout procedures and equipments for testing is included by this report.

But due to security conditions and other confidential matters the exact data and procedure won’t be included by the procedure but Imaginary data for introduction will be exists.

Go to the Next Page for General information about the process of sampling, testing and procedures of works in a Earth work mechanical Laboratory.

Most update information will be uploaded soon
