Experience of Using of Cold Emulsion Mix in the Republic of Latvia
Abstract
Technology of preparing and laying the cold emulsion mix in accordance with the General Technical Construction Specification for Road ROAD 94 of the Swedish National Road Administration had not been implemented in Latvia until 2000. Thus the relevant experience is rather limited: six road reconstruction projects have been implemented by using this technology since 2000. The author gives an introduction to the substantiation for selecting the emulsion asphalts in road reconstruction projects, the requirements set for such mixtures, as well as makes an analysis of a particular mixture and the problems related to the mixture usage and formation of defects.
The article provides recommendations for the necessity to start research in order to find a scientifically justified and practical usage of the cold paving technologies by taking into account the peculiarities of the Latvian natural resources and climate.
