Abstract


The peculiar circumstances of the preventive maintenance of the Tianjin area inrecent years, found that the uppermost layer of Tianjin asphalt road surface erosiondamage, direct withstand traffic loads and climate factors should have a considerabledegree of compactness, roughness, anti-slip, durable features. The middle layer is themost important layers bear shear stress in the surface layer of the asphalt road surfaceshould choose those skeleton dense graded asphalt concrete. Destructive of the layerbelow, under the invariable effect of the tensile stress, will produce fatigue damage, sothe requirement of the underlying layer should be so as to have effective anti-fatigueability. Increase the amount of asphalt so under normal circumstances, in turn, canimprove the fatigue life of the asphalt mixture under vehicle loads to improve itsability to anti-fatigue properties. Thick asphalt layer thickness in the constructionprocess of the asphalt road surface and improve the modulus can lower primary layerbottom tensile stress, and improve the fatigue resistance of the sub-base is veryeffective method, so thick asphalt layer play each asphalt layer functions at the sametime, should take the necessary measures to improve soil strength, to avoid thestructural rutting and soil foundation settlement road damage.The actual analysis, the to overhaul two cases Tianjin Zi highway overhaul andYuejin road traditional income maintenance in fact is not great, according to the abovecalculation results show that, if traditional conservation methods, and each repair costof a1m~2asphalt road surface is259.55/the m~2(Jin Zi highway overhaul) and236.55yuan/m~2(Yuejin Road overhaul), Tianjin Highway Administration data show that thenew construction of a highway required materials cost300-400yuan, so Whentraditional conservation spending almost and re-build a road spending less.Comparative analysis found that the traditional repair methods and preventivemaintenance methods were used by the Queensway Bridge twice the cost oftraditional repair methods146.52yuan/m~2(Admiralty highway repair), preventivemaintenance costs16.01yuan/m~2, and translated into an average annual cost ofusing traditional methods of repair costs to78.26yuan/square meter, while the use ofthe preventive maintenance cost is4.03yuan/m~2. Found through the calculation of performance indicators, traditional maintenance methods AND(-)=104.60, preventivemaintenance methods the APT(-)=124.12. The pros and cons of the two conservationmethods are self-evident.
