Lecturers from the department of building & construction engineering obtain a patent for the preparation and examination of emulsified asphalt paving mixtures Alkatyunic in Iraq

Lacturers Prof. Dr. Shaker Ahmed and Prof. Dr. Hassan Hamoudi Johnny ,L. Hussein Hamel from the Department of Building and Construction Engineering from the University of Technology's obtain patented industrial property department at the Central Agency for Standardization and Quality Control in the Ministry of Planning for the preparation and examination of paving mixtures emulsion asphalt Alkatyunic in Iraq.
This study aims to use mixtures emulsified asphalt cold for the establishment and maintenance of roads in Iraq as an alternative to the hot asphalt mixes, as a result of benefits from economic aspects, process and environmental.
The study focused on testing and evaluate the properties of material emulsified asphalt for use as a mix in road-paving Done taking into account a number of variables, such as the type of filler (cement Portland unusual and dust inflorescence), the style of mixing, compaction effort (75,150,225 blow), the treatment period (3 days) and a temperature of checking the stability of the Marshall (25 C).
As for the properties that have been checked to mix emulsion asphalt, it checks the density mass, air gaps, the gaps in the metal debris, absorption, stability dry Marshall, stability Marshall wet, stability Marshall remaining, creeping Marshall, indirect tensile and moisture resistance and compare it with the common specifications of Use It also made the comparison with the hot asphalt mixtures relevant Iraqi specifications.
