The deliberate results distortion problem in the road construction materials laboratory and its disposal

Abstract

Article considers the issue of asphalt concrete mixtures quality control necessity and analyses the road construction materials laboratory activity with detection description of an unacceptable random or a large systematic (shift) errors. In the process of producing asphalt concrete mixtures, there are many different factors that can influence their quality. In particular, such as: an inevitable change in raw materials properties, which is associated, among other things, with mineral components heterogeneity, for example, in grain size composition, moisture. There may be deviations in materials dosage, temperature variations and various other indicators, it is also necessary to consider subjective factor on performers part. Economic conditions for laboratory tests results distorting include: interest lack in maintaining information reliability and further strict control. There may also be a certain incentive for employee that determines appropriate behavior. Such incentives can both interest employee in providing reliable data, and can direct his actions towards a conscious distortion of information provided. At the present stage of laboratory testing level development of building materials, an important role in making management decisions is played by reliability and objectivity of information received. However, in road construction, laboratory test results distortion is quite large and plays an important role in industry. To increase results reliability of testing materials, recommendations are given for strengthening internal control in organizations, as well as external control by customer organization and / or regulatory authorities to ensure test results reliability.
