<p>Asphalt pavement quality is directly related to quality of asphalt mixed,while the quality of asphalt mixed is related to the mixed machine controller closely. For a long time different types of asphalt mixing equipment is equipped with a stability control quality asphalt mixing materials of the same type of asphalt mixing plant to produce different graded mixture was troubled by the quality of highway construction a worldwide problem.</p>
<h3>1.Asphalt quality objectives and requirements</h3>
<P>Asphalt mixture is a combination of mineral aggregate and asphalt mix from mixing in general. According to the material composition and structure divided into continuous graded, gap-graded mix. According to the aggregate gradation composition and size into dense graded porosity, there is semi-open-graded, open-graded mix. According to the nominal size of the maximum particle size can be divided into special rough formula (nominal maximum particle size equal to or greater than 31.5mm), Coarse (nominal maximum particle diameter 26.5mm), medium-grained (nominal maximum particle size of 16mm or 19mm), fine-grained (nominal maximum particle size of 9.5mm or 13.2mm), sand formula (nominal maximum particle size of less than 9.5mm) asphalt.</P>
<h3>2.Preparation of asphalt mixer machine </h3>
<p>Entering quality inspection of materials, machinery selection and matching, mixing plant site selection work should be done before mix the material.</p>
<p>3.Dust removal device technology </p>
<p>Asphalt mixing equipment have a first filter and secondary filter. The former is considered a pollutant coarse dust, the secondary in addition to a rough filter, but also to conduct a micro-dust removal of contaminants in the work.</p>
<p>The precipitator gravity settling chamber and cyclone are the main types, use centrifugation to separate dust particles will be trapped. As dust removal equipment gravity settling chamber and cyclone has many advantages: simple structure, low cost. Reliable operation, low maintenance costs. Unlimited temperature and pressure. Dry ash can be recycled, reused.</p>
