Pavement surface layer Milling depth control: there are rut but the middle or both sides without uplift, the roadway two milling each time the depth of the milling should be controlled at the design depth, rutting too deep or when the package should be gradually Increase the depth of milling, rutting too deep or behind the package and gradually returned to normal, milling should eventually reach the horizontal straight, the bottom of the groove flat. Milling with water when the principle of control: the use of manual ballast, hair dryer hair dust, from the cleaning, dust (when the dust release) point of view, pay attention to water control to minimize
Silos and dust removal equipment. Inside the asphalt storage tank, with the addition of anti-stripping agent equipment. And heated with a heat transfer oil to uniformly heat the asphalt to a predetermined temperature, and the use of asphalt which is bubbling or heating more than 185 ? is prohibited. The temperature of the mixture should be in accordance with the relevant specifications, the mixing time is generally not less than 50s, mixed with the mixture, all the mineral particles wrapped in asphalt binder for the degree. Asphalt mixture factory temperature control in the use of SBS modified asphalt 175 ? ~ 195 ?. For the carbonization, blistering and aqueous mixture to be abolished, with flowers, white spots, segregation and agglomeration of the mixture was also abolished.
