1.the basis of requirements
Asphalt base necessary for the formation, compaction, and may not have large potholes and cracks. Interface no obvious level, neat edge treatment. Slope and drainage to meet the design requirements. The construction of the surface layer can not make up the basis of large defects, construction workers approach to double-check basis, explain the situation and the consequences to Party A and supervision units, a more serious problem, the formation of written graphics and documents by the Party and supervision after being signed before construction.
Of asphalt-based maintenance (construction after the release period of time) for 28 days, must be greater than 20 days on a hot day.
2.Asphalt base back cover construction
I produced the asphalt back cover lotion 0.3-0.5Kg / m, the proportion of company policy and cement, quartz sand on the asphalt base back cover processing, generally use the scratch. Its role is to seal the pores of the asphalt-based isolation asphalt layer and the silicon layer. The basis of minor peacetime, to pay attention to the back cover material for basic leveling. Completely subject to the base surface pore closed. Construction is completed, the next step materials during construction until the material is completely dry.
3.Silicon buffer layer rubber construction
Silicon PU buffer layer of plastic material you want to add before the construction of water, add water ratio of 25 kg of plastic material plus 80 g of water, add water, stir evenly construction. Silicon PU buffer layer construction can also be appropriate to add the quartz sand. Different buffer layer thickness according to customer requirements is generally divided into multi-storey construction, each construction thickness of not more than 1.2 mm. Once construction is completed, the next pass until the material is completely dry or the next step materials during construction.
