The standard aims to unify equipment specifications to guarantee quality, compatibility, and safety in infrastructure projects. Manufacturer data include addresses and capacity ranges for various machines, facilitating informed procurement decisions.
This section provides exhaustive tables cataloging manufacturers of road and bridge construction machinery along with their product ranges and capacities.
Examples include:
Users are advised to consult Section A for detailed manufacturer data categorized by equipment type, with Sections B and C covering bridge parts and references respectively.
Key machines detailed for road building include:
Detailed specifications and contacts are referenced on pages 32 to 43 of the standard.
IRC SP 29 presents specifications and guidance for equipment utilized in bridge construction, including:
Bridge components such as anchorages, bearings, cables, and elastomeric expansion joints are also detailed, with manufacturer directories facilitating procurement.
Section B highlights critical bridge parts:
Design parameters like bearing load capacity, allowable rotation, and movement accommodation are tabulated for reference.
This section summarizes capacities and specifications, for example:
Air Compressors: Manufacturers like Atlas Copco offer piston compressors (171-335 cfm) and screw compressors (60-2000 cfm). Other suppliers include Consolidated Pneumatic Tool Co. and Holman Climax Manufacture Ltd.
Equipment listings with page references include paver finishers (pages 32-33), pile driving gear (page 33), and road rollers (pages 36-38).
Project scale should guide equipment capacity selection, with manufacturer catalogs consulted for detailed specifications.
The publication details mechanization equipment relevant to road and bridge construction, such as:
Formulas for output rates, compaction passes, and batching accuracy are provided alongside tables listing machinery types, capacities, and manufacturers to support efficient project planning.
While IRC SP 29 focuses on machinery listings, general quality control and maintenance recommendations include:
Sample tables for compaction control and formulas for density calculation are included to guide field practices.
The IRC SP 29 directory serves as a reference tool listing Indian manufacturers of road and bridge construction machinery and components. It is designed to provide quick access to company names and product information but does not certify or endorse suppliers.
Users should independently verify manufacturers before procurement. The directory does not contain technical formulas or design standards but aids in identifying potential equipment sources.
The document acknowledges possible omissions or inaccuracies and encourages users to submit feedback to the Indian Roads Congress for future editions. Suggestions should be based on practical experiences or technological developments.
The publication includes extensive tables and specifications on equipment and bridge components, and continual user input is key to maintaining its relevance and accuracy.
Frequently Asked
According to IRC SP 29, manufacturers of road rollers include Moses & Moses Engineers, producing rollers with capacities up to 2.5 tonnes, located at 2, D.B. Shanmugan Street, Kilpauk, Madras-600098. Other noted manufacturers are Sayaji Iron Engineering Co. Ltd., United Eight Brothers Engg. Works, and Vijay Engineering Co. Road rollers are categorized by type and capacity, such as small vibratory rollers ranging 2-5 tonnes, vibratory rollers between 8-12 tonnes, and static/tandem rollers from 5 to 15 tonnes. Specific manufacturers for vibratory rollers above 8 tonnes are not explicitly listed, and consulting updated directories or suppliers is recommended for those capacities.
IRC SP 29 lists a variety of domestically produced bridge construction equipment, including bituminous and concrete paver finishers, pile driving machinery, power trowels for concrete finishing, plastering machines, pumps for water and concrete slurries, road marking machines, road rollers (static, tandem, and vibratory above 8 tonnes), scrapers, shotcrete machines, tipping trucks, tower cranes and hoists, tractors and trailers, transit mixers, water tankers, and weigh batchers. Additionally, essential bridge components such as anchorages, bearings, cables, and elastomeric expansion joints are manufactured within India, supporting large infrastructure projects with locally sourced mechanization.
IRC SP 29 does not guarantee that the manufacturers included in its directory are registered with governmental agencies such as the Directorate General Technical Development, Small Scale Industries Department, or Directorate General Supplies & Disposals. The directory is intended solely as an informational resource and does not imply certification or approval by any government organization. Users should independently verify manufacturer credentials before procurement.
The directory in IRC SP 29 aids construction professionals by providing a comprehensive list of indigenous manufacturers and their product offerings in road and bridge construction machinery. It includes company names, product types, and details reflecting the latest mechanization trends and technology collaborations. This resource enables engineers and project managers to efficiently shortlist potential suppliers and understand the domestic equipment market, facilitating informed decision-making during procurement. However, it is not an approved supplier list and requires further verification.
IRC SP 29 specifies that bitumen sprayers are equipped with pressure pumps to ensure uniform application, featuring adjustable spray bars typically spanning 3 to 6 meters with multiple nozzles. They maintain bitumen temperature between 150-180°C using heating systems, and tank capacities generally range from 2000 to 5000 liters. Operating pressures fall between 1.5 and 3.5 bar, and sprayers are often mounted on lorries or trailers for mobility. Bitumen storage tanks, either mobile or stationary, have capacities from 10,000 to over 50,000 liters, incorporate steam coils or electric heaters for temperature maintenance, are insulated to reduce heat loss, and include safety features like pressure relief valves and temperature gauges. Constructed typically from mild steel with corrosion-resistant linings, these tanks ensure safe storage and effective bitumen application.
