Ecophalt Quality Assurance Specification(EQAS)
1.General
  This specification applies to a construction work of road paving using ECOPHALT mixture.
2.Raw meterial
 
  • Coarse aggregate : Based on KSF 2357
  • Fine aggregate : based on KSF 2358
  • asphalt: Based on KSM 2201 and KSM 2208
  • 3.Coloring : A predefined coloring by the authorities
     
  • Dark Brown
  • Dark Red
  • Black
  • 4.Mix Ration of Ecophalt
     
  • Gradation of Aggregate

    Size Shieve Pass(%)
    19M/M 100
    13M/M 95¡­100
    4.75M/M 10¡­31
    2.36M/M 10¡­21
    0.074M/M 2¡­7
      Polymer modified agent(DAMA)
     
  • Needs to stably adhere to asphalt.
  • Dye : There should be no problem in adhering to asphalt, and to be mineral-based dye. (if a coloring is required)

      Mixing ratio

     
  • Additive(asphalt) : 4.5¡­5.5 of the weight of aggregate
  • Dye(Each coloring) : 2¡­3% of the total mixture (if a coloring is required)
  • Polymer modified agent(DAMA) : About 1% of the total mixture in weight
  • 5.Reguirement of Ecophalt
     
  • ECOPHALT mixture will be tested according to the resistance test to plastic flow of a asphalt mixture using KSF 2337 marshall tester, and shall satisfy following criteria,
  • Stability(Kgf)=over 500
  • Flowage(1/100§¯)=20¡­40
  • Water permiability(§¯/sec)=over 1.0×10-2
        N.B.)Number of Compaction of the specimen is 50 times each side.
  • 6.Manufacturing process
     
  • It should be manufactured by Hot Asphalt Mixing Plant, and Adding DAMA shall be added by manual or automatic control equipment.
    7.Construction
     
  • Because the material is porous, the work has to be completed in a short period of time to control the temperature (use a finisher). To obtain a predefined density, second and third application have to be done after the first application.
  • Compaction of the third layer shall be done at a temperature of over 90¡É, and traffic has to be allowed at a temperature of lower than 50¡É.
    8.Test method
     
  • Testing aggregate: According to KSF 2357 and KSF 1247
  • Testing asphalt material: According to KSM 2201 and KSF 2208.
  • Testing asphalt mixture: According to KSF 2337.
  • Testing water permeability: For the case of ECOPHALT mixture, in-situ water permeability shall be used after completing the pavement.
  • Other tests
    Client shall instruct constractor after completing the pavement.
    9.Test and inspection
     
  • Testing: For the case of ECOPHALT mixture, test record from the constructor shall be used. Regarding manufacturing, Client can do intermediate test during the manufacturing to verify the quality.
  • Inspection: Visual inspection will be carried out by inspectors from the Client.
  • 10.Others
     
  • Considering that ECOPHALT mixture is porous, transportation distance needs to be less than 40km and the transportation time has to be within 1 hour.
