Program Of Old Concret Pavemnt Asphalt Concret Overlay Optimization And The Construction Process

This article on old cement concrete pavement asphalt concrete overlay of the program was discussed. Cement concrete pavement by the road survey and evaluation to determine whether the status of the old road for the construction of asphalt concrete overlay program. Construct Asphalt Pavement under the crack control measures in the different working mechanisms and their role in checking through the structure to determine the design of overlay structure. Road test on four different geological conditions, different traffic loads comparative analysis of the actual use, come in different construction and vehicle load conditions, the need to take a combination of overlay program type. Effective control of the asphalt to the construction of reflection cracks occurred in the construction process were analyzed, the use of high-performance modified asphalt concrete, increase the stress absorbing layer, geosynthetics, increasing semi-rigid base, cement grouting concrete slabs, pavement milling, high-performance asphalt crack filling and other construction measures and precautions specific measures are summarized and classified .
