Premix Carpet:

An open graded premix carpet, commonly called premix carpet (PC), is an open graded premixed material laid to a thickness of 20 mm and rolled, followed by a seal coat. The quantity of binder (normally 80/100 penetration grade) and aggregates are given in Table 6.

The premixing is done in a suitable mixer, the mix spread manually or by a paver, rolled by a 80-100 kN road roller to obtain a smooth surface. The premix seal coat or liquid seal coat is laid thereafter and traffic allowed after 24 hours. It has a life of about 6-8 years, and normally the seal coat is renewed once in 3-4 years.
