Bitumen Mastic

We offer impermeable, durable and deformation resistant bitumen mastic. Our bitumen mastic is a homogeneous mortar, which is a mixture of high-grade bitumen, mineral fillers and fine aggregates. Its consistency is such that it flows like highly viscose fluid at a temperature of about 200 degree Celsius but on cooling down it becomes hard.

Composition of Mastic

Bitumen blown grade

: 9%-10%

Lime stone dust (filler)

: 20%

Aggregated and dust

: 70%

Materials Required

  • Blown (Industrial Grade) bitumen

    1. Softening Point 55 degree C to 75 Degree C
    2. Penetration at 25 degree C in 1/100 cm 10 to 40

  • Limestone dust with calcium carbonate content exceeding 80%
  • Crusher dust
  • Aggregate


Equipment Required

  • Bitumen Mastic Cooker with mechanical agitation system mounted on wheels.
  • Tar Boiler for heating bitumen.
  • Wooden spreading and finishing floats.
  • Wooden Forms.
  • Mastic pouring bucket/wheel barrows as per requirement.
  • Hand hammers for anti-skid.


Methodology Adopted

  • The surface is cleaned with wire brush/broom.
  • Tack coat is applied.
  • The first stage shall be mixing of filler and fine aggregates and then heating the mixture to a temperature of 170 degree C to 210 degree C.
  • Bitumen is heated separately at a temperature of 170 degree C to 180 degree C and then mixed with pre-heated ingredients in the cooker.
  • The 2nd stage is incorporation of coarse aggregate and cooking the mixture for appropriate time to ensure that the contents in the cooker are at no time heated to a temp. exceeding 210 degree C.
  • The mixture is laid at site by the labour manually.
  • To control the thickness of the laid mastic, wooden forms are used.


Structure Works

Culvert is defined as a tunnel structure constructed under roadways or railways to provide cross drainage or to take electrical or other cables from one side to other. It is totally enclosed by soil or ground. Pipe culvert, box culvert and arch culvert are the common types used under roadways andrailways.

Thermoplastic Road Marking Paint

Thermoplastic Road Marking Paint (TRMP)
The Company uses TRMP conforming to the specifications laid down by the Ministry of Surface Transport (803.4)

Methodology and Application Procedure:

  • The surface should be free from moisture.
  • Dust, grease and any foreign matters are cleared off from the surface of the road to be marked.
  • Previous old paint marking is removed by wire brushes before application.
  • The compound is pre-heated to around 180 degrees (+/-10C) and transferred in application machine. Glass beeds are super-imposed through a dispenser or manual spray as per MOST specifications. Suitable marking compound is applied on the concrete.
  • Moslten TRMP is applied on the surface using Paint Applicators fitted with glass beed dispenser.
  • TRMP is laid only after marking is done.
  • Suitable primer is applied when TRMP is to be applied to concrete surfaces.
  • Temperature of application with this machine is maintained in the range of 180 to 200C.
  • Drops of glass beeds conforming to BS 6088 type B are sprayed while the paint through glass beeds gun attached with the paint applicator @250gms. Per sq. Mtr. Recommended coverage is 5 kg, TRMP per sq. Mtr on smooth surface at 2.5 mm thickness.
  • As per specifications the dying time of paint is 8m to 10 minutes based on the temperature.

To avoid personal hazards, special care is taken for workers safety and arrangements of first aid are made at Site.
