Asphalt pavement repair work, the following three aspects must pay attention to the essentials when one is pouring hot asphalt repair, pay attention to three points. 1, before pouring asphalt engineering calculation, use a hair dryer and a hook to the cracks in the dust cleared away debris; 2, when hot asphalt heating, the temperature should reach 130 ℃ or more, to maintain its good liquidity; 3, After the infusion is complete, the asphalt to be cooled to about 60 ℃, when the plasticity remain with the shovel to eradicate excess surface asphalt pavement to prevent contamination. Second, the surface layer of the thermal stoppage time, pay attention to three points. 1, when the disease has a hot baking asphalt pavement works much money, to be more when the temperature reaches 100 ℃ before starting work; 2, use the iron rake will harrowing road surface disease and eradicate large aggregate surface, in order to ensure repair effect; 3, after adding new material to comb uniform shaking, rolling dense. Third, when Wabu filling, pay attention to four points. 1, chiseled disease layer, after clearing waste, use a hair dryer to repair high voltage interface completely blowing ensure clean bed asphalt repair project, no debris and floating dust; 2, sprinkle sticky layer of oil to be covered with asphalt engineering interface Reservations telephone, and does not flow, can not have dead unleavened dough; 3, layered filling thickness or greater than 6, around the seam filler to be slightly higher, and to hierarchical compaction, compaction degree to be above 95%; 4, After the filling is completed, use the cold-fill plastic coating around the joints to prevent water infiltration.

By using the finite element method for semi-rigid base asphalt pavement modeling now common to analyze the stress-strain behavior under static and dynamic loading of each structural layer of asphalt pavement and the maximum shear stress with depth changes of the road, you can get the following conclusions: (1) from Asphalt Pavement table 0 ~ 3 cm area belong to three to compression. Pavement surface prone to water damage, with good resistance to water damage to structures should be designed in; region (2) from the road surface 2 ~ 10 cm in a high shear stress area, this part of the main withstand shear stress and vertical compressive stress, this area is primarily generated rutting layers; (3) the end of the asphalt pavement under tensile stress under static loads, tension and compression in the cycle is repeated action by the dynamic load case, is the main starting pavement cracking horizon. Engineering calculation asphalt, bitumen road through highway construction (certified), Pingxiang provided by Nanchang Engineering Limited asphalt road through the asphalt road projects.
