Calculation of the demand of asphalt paver
2., calculate the spreading rate of a spreaderSuppose a 9 meter paver theory, hourly paver 300 tons, but the actual theory can not reach the theoretical value, but also by the asphalt concrete production and transportation restrictions. Assume an average of 100 tons per hour and 10 hours a day.20000 / 100 10=20 / day.3. time limitIf the surface layer plan for 30 days, as long as it is not raining or other bad weather, so that one will be enough;If the schedule is tight or the weather is not good, the paver will be added.4., more than when paving, in order to ensure the quality of construction, such as seam problems, may choose side by side paving, you need more than 2 paver together.
1. calculate the amount of asphalt concrete firstPaving thickness X paving width X length, paving asphalt concrete paving material density = tonnagePaving thickness (m) = number of layers added, such as the top layer thickness + the surface layer thickness + the thickness of the following layer (the general diameter is not the same)Paving width (m) = width of each paving added;Paving length (m) = length of pavement to be laid.The density of asphalt concrete is usually 2.4~2.5 tons / cubic meter.Such as paving 20 kilometers, the surface layer has a width of 24 meters, paving two layer 4 cm +6 cm.Asphalt concrete =20000X24X (0.04+0.06) 2.4=20000 / ton.2., calculate the spreading rate of a spreaderSuppose a 9 meter paver theory, hourly paver 300 tons, but the actual theory can not reach the theoretical value, but also by the asphalt concrete production and transportation restrictions.
