A conventional prime coat emulsion is used as a binder for base materials and provides a secure bond between base aggregate and the subsequent asphalt layer. In addition to helping strengthen a road at the base level, a conventional prime coat can serve as a dust palliative.
Following application of the prime material and prior to application of the succeeding layer of asphalt mixture, allow the prime coat to cure and water or volatiles to evaporate prior to overlaying. This may take 24 hours for emulsion primes and 72 hours for cutback …
Prime Coat applications and facts: 1- It penetrates to the base layer and coats materials and aggregates on the base. It acts like a glue between the materials of the base and binds them to each other. 2- It makes the base layer hard and tough. Only 1 to 1.2 kg of Bitumen Emulsion is enough to be applied per each square meter whereas Cutbacks ...
A cationic asphalt emulsion for prime coat according to this invention can be used as prime coat for road base course - both untreated base course and treated base courseOnce the asphalts dry, they will securely adhere to the base course. It's convenient to use since no need to heat asphalt emulsion while using. The viscosity can be altered by adding the water, so no fire hazardous during heating.
Tack coat (also known as bond coat) is a light application of asphalt emulsion between hot mix asphalt layers designed to create a strong adhesive bond without slippage. Heavier applications may be used under porous layers or around patches where it also functions as a seal coat.
The prime coat is, however, one of the most prominent ones to notice. The low viscous bitumen emulsion is applied to a granular base. The bitumen emulsion may be used as a prime coat shell so that it can penetrate easily. Prime coats with cationic bitumen emulsion play an important role in ensuring the strength of the granular base.
