Old Cement Concrete Pavement Structural Design of Asphalt Concrete

0Mpa. Coagulation ± surface of asphalt layer thickness as the old asphalt concrete pavement layer thickness mainly based on economic conditions and the bearing capacity of pavement structure, the thickness of the surface layer should be between 6 ~ 10cm, depends on the thickness of the grass-roots structure of the overall strength of . Must be determined by design. Taking into account the effects of road drainage, requiring use of dense gradation asphalt mixture type. Porosity between 3 to 4%. Grass-roots should be located under the top cover layer. Under seal oil generally use two two materials, a drought region of oil can be used for a material. The thickness of the seal coat is generally between 8 ~ 1Omm. Generally made of asphalt concrete pavement asphalt surface two type two specific arrangements for the 6cmAC - 161 (6cm) 3cmAC - 13l +4 cmAC a 16l (7cm) 4cmAC - 13l +4 cmAC a 161 (8cm) 4cmAC- -13l +5 cmAC a 16l (9cm). 4cmAC a 16l +5 CmAC a 16l (9Cm) 4cmAC a 16l +6 cmAC a 16l (1Ocm). Treatment of shoulder and the hard shoulder because of broken concrete may be t appear between the uneven intensity of the problem. Must be based on the hard shoulder of the intensity of treatment. Treatment methods are generally first excavation to the hard shoulder of the bottom position and then the cement board determined the strength of the hard shoulder, if the hard shoulder of the deflection is greater than 12O (O.O1mm) and then dug under 3O ~ 40cm. Makes the structure of the hard shoulder of the sub-base thickness of 20cm ~ - gray gravel (cement stabilized gravel), 4 ~ 5cm gravel drainage layer (specific thickness from the thickness of the cement concrete slab) and covered with geotextile meeting if necessary add 1O ~ 20cm 20cm Lime's turning over soil. After completion of the above to ensure the hard shoulder of the top surface of the top surface of concrete and cement flush of lime on it (cement stabilized gravel) layer requirements and the simultaneous construction of the carriageway to ensure the uniform pavement structural strength to reduce the hard shoulder and the lane between the problem of uneven strength. Hu Hu Hu snapped a IdW】 world burst frog design base thickness of a base thickness re-determined based primarily on work. Fan primary mining evil thought roadbed width of two other anonymous beans degree structure + design based on the wine road pavement design green design parameters for the broken main advantage of loopholes in the whole cylinder strength of concrete aggregate traffic, the thickness of the top cover grass-roots love. Design of a startled the design calculation is given below,microsoft outlook, then touch the map. Conclusion In this paper, engineering practice and theoretical analysis of concrete pavement E [asphalt concrete pavement structure analogy method for the analysis and discussion of the major facilities proposed two step process based material requirements and minced meat or chopped Tam coagulation ± top mix asphalt overlay dig the design of sugarcane Augur surface structure by analyzing the main nomogram can draw the following conclusions: 17y, cement concrete pavement to be hoarse,UGG España, according to the actual identification of hundreds maintenance methods. Badly broken boards by Huan-dimensional method for setting a primary raw water, good roads ear structure if the water is mixed with the phenomenon of concrete pavement wizard void filling or spread by stable operation of the concrete panel can add or asphalt concrete surface layer of soil will be mixed panel broken hoop Primary and surface overlay. 12: Broken Concrete surfaces are = ji side] Asphalt Pavement Results May Coagulation two bearing plates must be coagulation tests to determine the top two panels hide the integrated module provides the reference number of car culture through the analysis of t-skid l3 mushroom.
