A prime coat is the application of a suitable bituminous binder applied to a non-bituminous granular base as a preliminary treatment before the application of a bituminous surfacing. The purpose of this research is to establish practical applications of successful prime coats to replace cutback asphalt. An

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.

A prime coat and its benefits differ with each application, and its use often can be eliminated, however it should be discussed with the paving contractor. If a prime coat is used, AEP (asphalt emulsified prime) should be specified as it is designed to penetrate the base material. The use of a tack coat is not recommended for use as prime coat.

Asphalt Prime Coat is also termed as emulsified asphalt, water diluted asphalt and Cutback aliphatic spray. Recently I have got the chance of working on a highway project somewhere in a mountainous cold-weather region. And I was amazed after finding the impact of climate on construction activities and materials used therein.

A prime coat emulsion is used as a binder for unbound base materials and provides a secure bond between base aggregate and the subsequent asphalt pavement layer. It helps strengthen the base level, can serve as a dust palliative, and help prevent moisture from penetrating the …

Table 1 from the Asphalt Institute Manual Series No. 6 (MS-6) shows the factors to be used in calculating the volume of asphalt material at 15oC. The factors are divided into two groups: A and B in Table 1 depending on the density. The specific gravity test results for asphalt are reported by the refinery or Department chemists.

At one time it was thought that a prime coat was an essential element of good pavement construction. However, in recent years some engineers have eliminated the use of a prime, especially when asphalt layer(s) (surface and/or base) is 4 inches or more in thickness.

The main usage of mc-30 is in prime coating, cold mix asphalts and bitumen paints. Prime Coats: MC-30 bitumen is fully capable of bonding the base to the first layer of hot mix asphalt. This grade of MC cutback bitumen is a unique primer which provides temporary seal to prevent the surface water from penetrating through the surface.

Due to frost concerns in our locale, subbase is usually thicker (12" to 48")and asphalt thinner, often 2" asphalt & 2" base course. So 5" sounds like a lot to me. There have been discussions here whether prime coat & tack coat are worthwhile, I think not worth it unless there are delays & exposure to weather, etc during construction.
