ENSURING THERMOPHYSICAL RELIABILITY OF A INTEGRATED TECHNOLOGY OF CONSTRUCTING A MULTILAYER HARDENING STRUCTURE IN COLD WEATHER
The article considers application of a probabilistic and statistical approach for prediction of a thermophysical mode while using an integrated technology for construction of a multilayer hardening structure (an asphalt-concrete pavement on a concrete and mineral road base was taken as an example) during a cold season. The authors present a developed technique of statistical modeling of a thermophysical mode of the road pavement that can ensure its thermophysical reliability. Design formulae and the required thermophysical parameters are given in the article. The technology is validated with laboratory experiments, field trials and good practices of road building. Application of the probabilistic and statistical approach makes it possible to successfully ensure thermophysical reliability of pavement quality and its economical effectiveness in cold weather.
