【正文】 houlderstyle slot machines, such as hair dryer mounted on trucks, Shi T locations scheduled to drag on a safe highway maintenance of order (JTG H302020) as the provisions of the construction area operations. ② slotted in accordance with the design of the slot size, good preconditioning Fslot machine slot depth, and then slotted operations, operations, according to crack width type of situation, timely adjustment slotted sizes to meet the minimum design requirements. ③ Shouldertotrough hair dryer to bed and cracks on both sides of the ejecta l0 till at least within the scope of cleaning dust thoroughly clean. ④ irrigation in the seam if the temperature below the 4:00slit. Irrigation with a sewing machine to be slotted parts of the preheating equipment for preheating, if not at this temperature preheat to fill the joints, sealants would reduce the cohesive force: if the temperature higher than the 4 ℃ at the joint meeting, From time to preheat, the general meeting of the joint after preheating better results, in sealed plastic heating temperature reached about 190 ℃ , with irrigation with a sewing machine for pressure nozzle Guaping sealant will be evenly Guanru bed and Crack drag on both sides of a certain width and thickness of the closure. ⑤ conservation irrigation joint sealant, sealed in plastic and the full cooling ejecta on the roads after sweeping clean, open to traffic. As cooling time for about 15 min, the specific time and opening up under the traffic situation in temperature flexibility ⑵ nonslotted repair (the traditional repair method) Nonslotted for the repair of microcracks to repair, according to the use of different materials, such repair method can be divided into hotand coldtwo kinds. ① AUl lO ^ heavy oil traffic hot asphalthotmelt asphalt construction machinery and equipment spraying equipment (installed in the car project). The rotation of the preparatory work → preparation → heating melt down AHl l0 ^ heavy oil traffic around the asphalt cracks → remove dust → straddle spraying hot melt asphalt oil → handMoping natural cooling → open traffic . ② modified emulsified asphalt coldconstruction Modification of emulsified asphalt is a mixture of liquidcold materials, machinery equipment without special request, after the stirring scene of artificial joints Guatu letters (at least three times) → preparations for the construction technologyartificial joints → Banliao → people on the Guatu → → curing → secondary Guatu → curing → three Guatu → Kang → opening of traffic (curing time l5 ~ 20 min). ⑶ traditional repair method for repairing and slotted the parison ① to the traditional repair method, whether it is reused to transport oil or pieces of asphalt emulsion asphalt irrigation joints, although Oxfam j equipment almost no input costs, lower cost of the initial application T, but with the surface temperature of contraction and the grassroots up to 1 year, after the repair of cracks and joints location of the original irrigation rec
