NH-744 Corridor Connector
Madurai Outer Ring Road Viaduct & 4-Lane Elevated Bypass
High-speed 28.4 km grade-separated corridor bypassing core Madurai congestion, including twin viaducts, 3 major vehicular underpasses and automated toll plaza infrastructure.
Scope of Work & Structural Compliance
Complete structural accountability adhering to Indian Roads Congress (IRC) codal mandates and MoRTH 5th Revision guidelines.
Civil & Highway Alignment Engineering
- arrow_right_altDeep Earthwork & Subgrade Stabilization: Bulk cut-and-fill across high-plasticity black cotton soils, stabilised with lime-slurry injection to achieve a resilient modulus CBR of 12%.
- arrow_right_altPavement Composition: Granular sub-base, wet mix macadam, dense bituminous macadam with VG-40 bitumen, topped with a stone matrix asphalt wearing course.
- arrow_right_altElevated / Grade-Separated Works:Post-tensioned PSC girders precast off-site and transported on hydraulic multi-axle trailers, erected with laser-guided alignment.
- arrow_right_altDrainage & Hydraulics:Reinforced concrete longitudinal side drains and RCC box culverts designed for one-in-fifty-year flash storm hydrological profiles.
Underpass & Interchange Complex
Construction of major vehicular underpasses allowing uninterrupted local traffic flow without grade interruption.
Third-Party Independent Testing
Direct oversight and QA verification conducted by the Department of Civil Engineering, National Institute of Technology (NIT) Tiruchirappalli.
Roads & Highways Code Compliance
Executed to the applicable Indian Roads Congress, MoRTH or RDSO specification for this class of work, with records available for departmental audit.
Dedicated Machinery Fleet Mobilised
Vögele Super 1800-3
High-compaction tracked asphalt paver with AB 500 TV screed, capable of continuous 8.5 m paving widths with laser sensor grade control.
Hamm 311 Tandem Rollers
11-tonne heavy tandem vibratory compactors with integrated HCM asphalt compaction meters, used to guarantee 98% laboratory density.
SANY 150T Crawler Crane
Heavy-duty lattice boom crawler crane mobilised for tandem lifting and millimetre-accurate placement of 72-tonne PSC bridge girders.
Schwing Stetter M1.25
Fully automated on-site concrete batching plant with aggregate moisture sensors, chilled water dispensing and computerised micro-dosing.
Execution Milestones & Phasing Velocity
Chronological phasing of the critical path operations for this contract.
Geotechnical Subsurface Inquest & Site Mobilization
64 rotary core drillings across the full alignment. Field QC laboratory, aggregate stockpiles and dual weighbridges established at Ch. 12+000.
Subgrade Stabilization & Embankment Completion
780,000 m³ of earthmoving finished. Subgrade passed DCP trials with compaction consistently above 97% MDD.
Viaduct Pier Caps & PSC Girder Launching
All 24 elevated spans erected, with coordinated night-time tandem crane manoeuvres over railway crossings.
Dual-Layer DBM & Stone Matrix Asphalt Surface
Twin sensor pavers working in echelon to eliminate longitudinal cold joints. Roughness index measured under 1,800 mm/km.
Early Handover & Departmental Quality Acceptance
45 Days EarlyJoint walkover inspection with the TNHRRD Superintending Engineer and commissioning of the automated toll plaza.
“TTK Construction demonstrated exemplary execution discipline throughout the Madurai Ring Road Corridor project. Their decision to mobilise their own fleet of high-tonnage sensor pavers and cast bridge girders off-site significantly accelerated the timeline. The contract was handed over 45 days ahead of schedule with zero defect liability notices.”
