Municipal Roads

Continuous operation of the equipment

Environmental protection to meet the standard

Municipal roads project for asphalt plant

Municipal roads are an important driving force for urban development, which can effectively enhance transportation efficiency, improve the quality of life of residents, enhance the image and competitiveness of the city, and promote sustainable urban development. However, municipal road construction is highly sensitive to construction efficiency, environmental standards and social impact. How to realize efficient production and fast paving of asphalt mixtures in limited urban space? Choosing the ideal asphalt production and paving plant is crucial.

Municipal roads project construction process

Macroad, as a qualified asphalt mixing plant manufacturer, is well versed in meeting the needs of municipal road projects and can provide optimal solutions in terms of equipment selection, construction process optimization and meeting local environmental requirements to help the project succeed.

How Core Equipment Components Solve Municipal Road Construction Issues

  • Complex construction environment: the operation area is located in densely populated areas, which needs to take into account the traffic diversion and the impact of public life.
  • Diversified material requirements: covering main roads, sidewalks, non-motorized roads and other scenarios, which need to be adapted to different grades of asphalt and mixture formulations.
  • High environmental requirements: strict control of dust, noise and exhaust emissions, night construction needs to comply with the city’s environmental regulations.
  • Intermittent production requirements: road maintenance projects show “multi-batch, small batch” production characteristics

1.Asphalt quality can not be guaranteed: multiple batches of asphalt can not realize the accurate proportioning

  • Improve aggregate weighing precision: Equipped with hot aggregate metering hopper with cumulative measurement, as well as overflow and waste tanks, with automatic compensation for fallout and overweight alarm and locking function;
  • Improve the weighing precision of powder: the discharge port of powder bin adopts valve port control; the powder metering hopper adopts cone design
  • Adopts dynamic precise control of secondary measurement technology: according to the amount of stone material on the asphalt of the secondary correction measurement, strictly guarantee the oil/stone ratio, to avoid the loss of asphalt

2.Inefficiency and tight schedule: Site area constraints on equipment deployment, tight schedule for municipal projects and high quality requirements

  • The equipment adopts structured modular design and is equipped with a chassis, which is convenient for disassembly and assembly and ensures short downtime of the equipment.
  • The use of high-precision boring machine to process the shaft hole, to ensure the concentricity of the shaft end, the mixing shaft in the process of bearing wear and tear is small, long service life, to reduce the failure due to wear and tear of the large shaft, reduce the downtime brought about by the maintenance.
  • The mixing drive adopts the direct connection mode of motor and reducer with the big shaft, non-traditional chain transmission, good transmission synchronization, to ensure that the mixing shaft mismatch is avoided due to unsynchronized rotation, reduce the incidence of failures, and ensure the continuous operation of the equipment.
  • Vibrating screen adopts 4 layers of double vibration motor linear screen, linear vibrating screen maintenance is convenient, vibration motor work 1500 hours before maintenance, reduce the maintenance time, reduce the impact on the work schedule5. The burner is equipped with a unique blowing pipeline, which eliminates the need for frequent manual cleaning of the burner gun, effectively prevents the oil circuit from clogging, reduces the maintenance cost, and reduces the loss of downtime caused by equipment maintenance or overhaul.
  • Optimized design of elastic tensioning device (spring), which plays a buffer role when the plate chain is working, reduces the risk of wear and breakage of the plate chain, and reduces the failure rate.

3.Environmental risks: residents’ complaints about dust, asphalt equipment noise nuisance

  • High-pressure pulse bag filter, more thorough dust removal, higher efficiency, to meet the local environmental requirements, to avoid complaints due to environmental problems
  • The screening system is equipped with an exhaust pipe outside the screen body, which effectively prevents the dust from escaping, and the fully closed structure, negative pressure dust prevention, no dust leakage, avoiding environmental pollution and equipment downtime caused by dust pollution.
  • Multi-stage dust removal system, a gravity dust removal or worm shell dust removal or cyclone dust removal, secondary bag dust removal or water dust removal, so that the dust according to the size of the particle size grading recycling use, to ensure that the equipment environmental protection to meet the standard

Core Equipment Selection Guide

In the construction of municipal roads, Macroad provides batch type asphalt plant, which can accurately meet the high standards of grading accuracy and mix quality required by municipal projects by virtue of its precise proportioning process, which can independently complete the drying, weighing and forced mixing of aggregates. Moreover, the equipment provides 40-3200t/h multi-level capacity configuration, which can be flexibly adapted to the typical needs of intermittent material supply and multi-segment construction of municipal projects.

For roads with low traffic and pedestrian traffic, Macroad recommends the more cost-effective drum mix asphalt plant. The continuous production process of a drum mix asphalt plant provides a constant supply of asphalt to meet the needs of municipal roadway mass production.

Macroad engineering team through the integration of equipment selection, site planning and operation and maintenance training of the whole process of service, to ensure that the quality of municipal road construction and construction efficiency of the double enhancement.
