Poly Changda Engineering Co., Ltd. 2025 Asphalt Emulsifier Centralized Bidding Supply Project

Project Background

Poly Changda Engineering Co., Ltd. is a large comprehensive construction enterprise focusing on national highway and municipal road engineering construction. In its 2025 annual centralized procurement tender for road chemical additives, the company put forward unified, long-term and large-volume supply requirements for asphalt emulsifiers and modifiers, with strict standards for product stability, batch consistency, climate adaptability and comprehensive technical after-sales support, to satisfy the construction demands of multiple highway reconstruction, new-built pavement and road maintenance projects across the country within the whole year.

Project Details

Parameter

Detail

Client

Poly Changda Engineering Co., Ltd.

Project

2025 Annual Centralized Procurement Project of Asphalt Emulsifiers & Modifiers

Location

National multi-regional road construction projects under Poly Changda

Application

New highway paving, cold regeneration reconstruction, micro-surface maintenance engineering

Products Supplied

Full series of asphalt emulsifiers, SBS modifier, SBR latex

Project Scale

Annual bulk centralized supply for dozens of road construction sections nationwide

Challenges

01 Unified strict product quality standards

The centralized bidding unifies the testing indicators of emulsifiers and modifiers for all branch projects; all batches of products must pass third-party sampling inspection, with zero tolerance for unstable performance between batches.

 

02 Cross-regional climate adaptability requirements

Poly Changda’s construction projects cover southern rainy high-temperature areas and northern low-temperature frost areas. The supplied emulsifiers and modifiers need to maintain stable construction performance under extreme temperature and humidity differences.

 

03 Long-term continuous bulk supply demand

The whole-year centralized procurement requires phased batch delivery, matching the staggered construction schedules of dozens of projects, with zero stock-out risk at each construction site. 04 Full-cycle technical matching service

Different types of road projects (cold regeneration, micro-surface, new pavement) require customized construction proportion schemes, and on-site technical guidance needs to be provided for each construction section at any time.

Solution

HDC’s R&D and technical team deeply analyzed Poly Changda’s tender specifications and the construction conditions of its projects in different regions, and formulated a standardized whole-year supporting supply solution:

Results

· Won the 2025 annual centralized procurement bid of Poly Changda with stable product indicators and comprehensive supply & technical capacity, and successfully signed a long-term supply cooperation framework agreement.

· All delivered batches of emulsifiers and modifiers passed third-party sampling inspection, with no unqualified products during the whole year of supply.

· Products adapted to construction environments in north and south China, effectively solving pavement cracking, rutting and peeling problems in different climate zones.

· Phased delivery fully matched the construction progress of all projects, no construction shutdown caused by material shortage occurred throughout the year.

· Highly recognized by Poly Changda: The client affirmed HDC’s stable batch quality, flexible bulk supply capacity and responsive nationwide technical support, and reached intention to renew the cooperation for the next year’s procurement.
