Highly durable asphalt modifier made from waste PET NEWTLAC 5000

Achieving a balance between the effective use of waste PET and high durability pavement

Background & challenges

Aging social infrastructure and shortage of civil engineers

The aging of social infrastructure has become a serious problem, and it was reported that by 2033, approximately 60% of roads will be more than 50 years old. Furthermore, while periodic pavement inspections and the establishment of road maintenance methods is required in line with revisions to the Road Traffic Act, etc., the construction industry is faced with another serious problem stemming from a shortage of civil engineers who play a key role in the maintenance of our social infrastructure.

Effective use of recycled PET waste in high durability asphalt modifier
NEWTLAC 5000 series

Using waste PET (discarded Polyethylene Terephthalate), Kao developed NEWTLAC 5000 series, a high durability pavement modifier, and established a technology to promote positive recycling. NEWTLAC 5000 is a unique asphalt modifier developed by Kao that combines pavement durability enhancement with waste plastic recycling.
