Hubei Traffic Investment Qitai Highway Surface Project

Project Background

The Qitai Highway project, developed by Hubei Traffic Investment Group, is a key regional transportation infrastructure connecting central Hubei Province. The project required high-quality surface materials for the highway pavement structure, demanding asphalt emulsions and modifiers that could withstand heavy traffic loads, temperature variations, and long-term durability requirements.

Project Details

Parameter Detail
Client Hubei Traffic Investment Group
Project Qitai Highway Surface Project
Location Qitai, Hubei Province, China
Application Highway pavement surface layer
Products Supplied Medium-crack asphalt emulsifier, SBR latex (40%), anti-stripping agent
Project Scale Multi-kilometer pavement section

Challenges

01 Heavy traffic load

the highway corridor experiences high truck volumes, requiring pavement materials with superior rutting resistance and fatigue life

 

02 Temperature variation

Hubei's climate subjects pavement to significant thermal cycling, requiring emulsions that maintain adhesion across freeze-thaw cycles

 

03 Quality compliance

project specifications required full material testing documentation and third-party verification for government approval

 

04 Supply schedule

surface construction required coordinated material delivery aligned with the project paving schedule

Solution

HDC's technical team conducted a thorough review of the project specifications and local climate conditions, then recommended a custom asphalt emulsion system:

Results

· Pavement surface completed to project quality specifications and accepted by the client without rework

· Improved crack resistance observed in early service — attributed to SBR latex modification

· Moisture damage resistance verified through laboratory testing of core samples

· Smooth delivery schedule maintained — no material shortages or quality delays during the paving season

· Positive client feedback — Hubei Traffic Investment Group recognized HDC's technical responsiveness and product consistency
