1. Development of drainage asphalt pavement

Drainage Asphalt Pavement-Water Retaining Asphalt Pavement-Water Permeable Asphalt Pavement

2. Advantages of drainage asphalt pavement

(1) Excellent security

No puddles on rainy roads, no water film, no water fog, good sliding resistance, and good visual effects. Greatly improved the safety of driving in rainy days.

(2) Reduce water mist

(3) Improve the visual effect at night on rainy days

(4) Anti-slip

(5) Excellent noise reduction performance

(6) Urban heat island effect

Effectively reduce ground temperature 2 ℃ -3 ℃

3. LY-GNJ direct cast modified OFGF-13 asphalt mixture mixing process

• Aggregate heating temperature 180 ℃ -190 ℃

• Matrix asphalt heating temperature: 150 ℃ -165 ℃

• Mixing temperature 180 ℃ ± 5 ℃

• Add high-viscosity to mixing tank and heat-collect dry mixing for not less than 15s

• Spray asphalt into wet mix for not less than 45s

• Total mixing time is not less than 60s
