THIN WHITE TOPPING (TWT)

THIN WHITE TOPPING are originally developed in the USA in 1918 as a quick cost effective and long lasting rehabilitation solution for asphalt pavement. TWT is the covering of an existing asphalt pavement with a layer of special design cement concrete, white toping is a rehabilitation technique in which 100 to 200 mm thick layer of cement concrete is placed over a milled surface of asphalt pavement. The overlay Thickens and joint specifications are decided depending on the traffic load. Special M-40 grade concrete is design and laid with the combination of polypropylene fibers. They are added to mix for increasing resistance to plastic shrinkage and to promote additional tensile strength. Our expert team extends assistance in design and execution to carry out TWT projects in India. We uses special high frequency needle vibrator (VPM 12000) and further truss paver are applied for compaction and leveling, Joint are cut longitudinally and transversely with in 24hr with special design concrete cutters and curing us done with curing compound. Our company have executed first project of TWT in the year of 2005 at WESTERN COURT IN NEW DELHI UNDER CPWD.

CONCRETE MIXING & PLACING:

The concrete will be produced in fully automatic batching plant as per required design mix and will be transported in transit mixer.

Form Work:

1. M. S. Channel of a required thickness will be used as form work for casting of PQC.
2. M.S Rail track channel will be fixed by helping wooden blocks and M.S jack for travelling the fixed form sensor paver

PLACING OF SEPARATE MEMBRANE, DOWEL BAR, TIE BAR

Separate membrane of PVC sheet as per required thickness will be place on DLC before casting of PQC as per the design in charge, placing of the Dowel Bars & Tie Bars to be place in the panel before casting ofthe PQC as per IRC-58.

COMPACTING & LEVELING WITH SENSOR CONCRETE PAVER

PQC will be place with Sensor Paver as per required paving width. Concrete will be compacted and leveled with Auto leveling sensor system.

MANUAL BULL FLOAT

Once the concrete has been compacted and leveled its surface will be smoothen by means of manual bull floating, the process will be finished before excess moisture or bleed water appear on the surface.

MECHANICAL FLOATING: (IF REQUIRED)

Once the concrete has been compacted and leveled its surface will be smoothened by means of Mechanical Floating.

TEXTURING

Just before the concrete becomes non-plastic, the surface will be textured with an approved handled steel or fiber broom conforming to the stipulations laid down in IRC:43. The broom tool will be pulled gently over the surface of the pavement from edge to edge.

CURING OF PAVEMENT

JOINTS SPACING & DEPTH

The locations and the type of joints will be as per drawings. Proper joint spacing is necessary to control cracking of the concrete, the dummy joint will be cut with in 48 hours by Diamond Concrete Cutting Machine. Depth & Width of the cut as per thickness of the pavement.

JOINTS SEALING WITH SEALANT

Longitudinal, Construction, Dummy & Expansion joints will be sealed as per the specification with approved Joint as per Engineer In Charge.
