1.Application of pouring sealant during road maintenance work
During the process of pavement maintenance process by pouring sealant to pavement surface, it need to be prepared in advance fully. There different levels of damage appear during the construction of the building highways at the past, which is the main reason by not maintain properly. The construction unit should take this as a warning, master effective conservation technologies for the future development of construction projects have made outstanding contributions. Pouring sealant is an effective process for quality road construction. 2.1 Preparatory work before construction First, in order to ensure the construction quality of road works, we must first done full preparations before construction. According to the relevant provisions of the construction, the first sealant temperature should be controlled within the scope of the project needs, the length of the crack sealant for use plays a direct relationship, generally speaking, each 8m long cracks need to use 1kg sealant specifically calculated as the crack length, depth and width multiplied and multiplied 0.12kg, the final result is obtained sealant usage. 2.2 Heating Before use of the sealant, it need heat treatment first ,put it in the heating compartment, removed after melting, hot-melt kettle meet the requirement of bituminous material uniformity , the general heating temperature is about 193 ℃ , in a high-temperature environment, points to note when heating is required to ensure homogeneity, the use of heat transfer fluid and hot air heating equipment in the main media, to avoid the emergence of scorched condition of excessive heating. Typically, the rubber modified asphalt is the preferred sealant. Repeat the heating process but will make the sealant aging conditions, produce grit, so be sure to pay attention to the temperature and the degree of heat. 2.3 Other preparation Before construction work area should be closed, and arrange the reasonable set of safety instructions signs. While slot machines and crack sealing conduct a comprehensive inspection to ensure that its quality meets the construction requirements. The actual situation of pavement crack depth analysis, formulation with suitable pouring solution.
