The Research On Asphalt Emulsion Cold Recycling Technology

Traffic is a profession of the resource occupying type and energy consumption type,the highway construction means to occupy the land for a long period.Therefore according to central requirement the continued development of highway must go to the way of economizing resource and protecting environment,deal with the relation of the traffic development,economizing resource and protecting environment.The adoption of cold recycling technology which could reutilize pavement materials is in advance with the present trend towards sustainable development, and therefore is a burning issue lying before the researehers and engineers.Cold recycling technology of asphalt pavement will a new kind of technique that repeated using the old asphalt material of the road surface,according tothe structural feature of recycling structural layer properly joining partial newaggregation or fine aggregate and pouring into the proper water and stable additionalthings to form a structural layer again. The major research of the paper is a technology problem that a feasibility study that recycling bituminous mixture with cement and emulsified asphalt to build the pavement base and how raising cold in-place recycling highway performance and mechanics performance.Base on the characteristic of cold recycling technology,its advantage is analyzed in this paper. Designing a series of test to research the highway performance andmechanics performance of the three kinds of the gradation and compare with recycling performance of these,base on above-mentioned research discuss the influence of performance and composition of raw material to recycling mixture performance.The parameter value of feasible scope,resist-intention, resist-intention elastic module and crack intention is given out.Experiment result is tested through in-place examine of experiment road and analysis to corrent and perfect the experiment conclusion,at the same time having introduced construction technology and quality control, economic benefits and social benefit.In a word cold recycling technology has many advantages that economizing capital and alleviating environmental pressure,it is popular application that must bring un economic benefits,social and environmental benifit.
