Research On Regeneration Scheme And Construction Technology Of Hot Mix Plant Recycling

Since the construction of the highway network, the new highway technology matures,but in the maturing process will be left behind many problems, in addition to the obviousproblem of environmental pollution and resource waste problem more and more attention,more importantly, increasingly outstanding problem is due to various aspects of theperformance of the original highway was built in the exploratory stage, although theshort-term to meet the requirements, but the long-term performance degradation is serious,resulting in much lower than the design life of life, coupled with a greater burden of roadtraffic, road damage more frequent maintenance of highway maintenance tremendouspressure. In view of the road facing massive expansion and overhaul of the environment, theneed for regeneration programs necessary research. Regeneration program selection, designand construction quality monitoring regeneration programs start to deepen the study of theapplication of regeneration at the technical level, so as to achieve maximum utilization ofresources.An article relies stone highway expansion project, renewable technologies at home andabroad from the existing analyzes the applicability of each method of regeneration,regeneration method Shian proposed renovation and expansion of high-speed andinvestigate domestic hot mix plant regeneration has been the transformation of the road oldmaterial blending ratio and the regeneration horizons choice and performance combinedwith graded stone An old material after screening of stone An existing old material blendingproportion improvements and asphalt degree from aging, blending the old rate and feedwhether to add modifiers aspects of a high proportion of hot mix plant regeneration schemeproposed selection criteria. On the high-speed high proportion of stone mix gradation study,suggestions for improvement on the old material control, selection and gradation adjustment,and construction operations that need attention to improve the proposal, put forward a set ofhigh proportion of renewable mix design solution.
