Highway Construction Solution
Solution Background
With the large-scale construction of national expressways, trunk roads and bridge projects, pavement paving, bridge subgrade treatment and road long-term maintenance put forward high requirements for road chemical additives. Frequent temperature changes, long-term heavy vehicle loads and complex foundation conditions require diversified, high-stability pavement materials. Wuhan Huadingcheng New Material Co., Ltd. supplies a complete set of highway supporting materials including asphalt emulsifier, asphalt modifier, anti-stripping agent, warm mix agent, road lignin fiber and anti-rutting agent, to realize safe construction, stable pavement forming and long service life of highway projects.
Project Challenges
01 Pavement cracking & aging caused by temperature difference
Alternating high and low temperature in four seasons easily leads to asphalt aging, pavement cracks and aggregate falling off.
02 Permanent pavement deformation under heavy load
Overloaded vehicles cause pavement rutting, road surface depression and damage to the overall structure of the pavement layer.
03 Poor bonding performance between asphalt and aggregate
Water seepage and vehicle impact will cause asphalt peeling from aggregate, resulting in pavement damage in advance.
04 High energy consumption of hot-mix asphalt construction
Traditional hot asphalt mixing needs high heating temperature, bringing high energy consumption and harmful flue gas emission.
05 Insufficient overall stability of asphalt mixture
Common asphalt mixtures have poor high-temperature stability and low anti-deformation ability under long-term traffic load.
