<p>1.The test must be carried out before construction raw materials, inspection before use. The test must be carried out before the construction of the mix, when the confirmation does not change the material before use. Construction should be based on the time change of emulsified asphalt and mineral aggregate levels of residue moisture content must be timely adjustment of mix to make it meet the requirements to ensure that the slurry mixture work ability, and construction</p>
<p>2.Site mixing roduction in the construction should be carried out on-site mixing sealer, the sealer through metering equipment, field operations by the robot, ensure emulsified asphalt, water, mineral materials, fillers, etc. can lead a certain mixing ratio, carried out by mixing box mixing. Since the slurry mixture has the characteristics of fast breaking, operator must control the construction consistency, to ensure uniform mixing and mix construction workability.</p>
<p>3.Site paving: According to the road width and paving width to decide the number of pieces of paving width, driving directions and press start paving. Paving the robot starts operating as required, so that the mixture drip into paving groove, paving the tank when 1/3 of the mixture when the signal from the car to the driver issue. Sealer should be a constant speed, with a speed of about 20 m / min, to ensure uniform paving thickness, paving the end of each car to clean up the rubber blade and paving paving groove after groove were sprayed baking scratch net, keep the tank clean paving.</p>
<p>4.Inspection of percentage of construction: In the calibration of the dosage unit, paving slurry mixture, its aggregate ratio how: on the one hand can be empirically observed; the other is the physical inspection of the hopper and the emulsion tank and the amount of time spent paving inverse ratio and Whetstone displacement, do the former checking, if there are errors, then do further investigation.</p>
<p>5.Good conservation timely early traffic opening, after paving slurry seal is not cured before molding should prohibit all vehicles and pedestrians, should be set up specifically responsible, good early conservation, in order to avoid the destruction of the road, if traffic or strict closure the original road is not completely clear and other reasons, resulting in local disease, should immediately be repaired with a slurry, to prevent the expansion of the disease. When the mixture reaches adhesion 200N.cm, the beginning of the end of curing, when the vehicle is traveling above no obvious signs, traffic can be open.</p>
