Impaction Analysis Of Vehicle On Pavement Structure At The Early Time In Strength Formation Of Cold Recycled Mixture

With the continuous economic development, the transportation is more and more important.Inrecent years， the state has made great efforts to develop the transportation with building andrebuilding roads.Waste road material that piled up and abandoned in the reconstruction projectcauses tension venues and a waste of resources.This paper， by means of test and looking up other data， makes a conclusion of cheperformance growth law of cold in-place recycling mixture and other semi-rigid material and findsthe range of splitting strength and compression modulus of cement stabilized macadam and coldin-place recycling mixture.Meanwhile,this paper sdudies a new paving technology calledasynchronous continuous paving technology. This paper focuses on asynchronous continuouspaving method of subbase and substratum, asynchronous continuous paving method of substratumand grass-roots, asynchronous continuous paving method of subbase,substratum and grass-roots.Inthe most unfavorable conditions,the deflection of the suiface of subgrade and the maximum valueof the layers of bottom stress and strain are copared with the standard value.This has verified thefeasibility of the technology and provided a theoretical basis for the technology.This paper makes aconclusion of asynchronous continuous paving technology.Keywords：express way；Roadbed；cutting；Intercalation shear stress； optimization；...
