Analysis And Research Of Road Cold Regeneration Material Mechanics Performance Test

Cold recycling technology is the use of cement, lime, cement, fly ash, bitumen emulsion, foamed bitumen, cement and emulsified asphalt, etc., as additives, the old Cold Asphalt Pavement recycling technology in road performance is analyzed to pavement performance able to meet the performance requirements and base material used in road base, the paper at home and abroad based on the results of research techniques, combined with our now widely used in semi-rigid asphalt pavement structural characteristics, and Shen business lines of the old asphalt pavement specifications, to study cement, lime, cement, fly ash admixture of cold recycling technology for the road performance and application and promotion in the Shenyang region.This series of cold recycled mix design laboratory tests, were used to test for cold recycled materials and cold recycling mix physical and mechanical properties were analyzed. RAP material, including broken gradation analysis and analysis of physical properties broken. Mixture of cold recycling unconfined compressive strength, splitting strength, anti-erosion properties, frost resistance, fatigue properties and drying shrinkage test indicators for analysis and statistical test data evaluation, to look for the cold recycled material with the stiffness strength admixture dosage cold recycled materials and how much age variation of health, from strength, stiffness and water stability, frost resistance, fatigue properties and shrinkage performance analysis of cold recycled materials and the corresponding conventional semi-rigid material difference in pavement performance The study, based on the nature of raw material mixture of cold recycling performance impact.In this paper, thick layers of cold recycled structural design analysis, based on statistical analysis of test data design parameters recommended cold recycled materials for cold recycling technology designers, builders and researchers to provide some further suggestions. Shen camp last line of secondary road with cold recycling technology for the construction process were analyzed, including analysis of construction preparation, construction, process analysis and construction precautions.Through experimental analysis the following conclusions can be to cement, lime, cement, fly ash as admixture of cold recycling old asphalt pavement technology is more applicable to our present as a road maintenance technology, with good technical, economic, social and environmental benefits, especially the lack of sand and gravel material region, it is in our road maintenance technology application.
