When placing prime coat through an intersection where it is not possible to keep the lane closed, the prime coat may be covered immediately following its application with fine aggregate mechanically spread at a uniform rate of 2 to 4 lb/sq yd (1 to 2 kg/sq m). (2) Aggregate Bases. The prime coat shall be applied uniformly and at a rate that will preparation of the surface and furnishing and placing the materials and application of blotting materials including all labour, equipment, tools and incidentals necessary to complete the work prescribed in this Section. Pay item shall be: 3/6/1 Bituminous Prime Coat (plant placed) Square Metre or 3/6/1 Bituminous Prime Coat (hand placed) Square Use of Prime Coat At one time it was thought that a prime coat was an essential element of good asphalt pavement construction. However, asphalt prime materials and the gradation of aggregate bases have changed over the years and applications of prime are no longer necessary for most asphalt pavements. For flexible pavements, the graded subgrade or the top granular base layer may be prepared with a prime coat. A prime coat is a sprayed application of a cutback asphalt or asphalt emulsion (AE) applied to the surface of untreated subgrade or base layers.

7.1. The roadway must be measured first to determine the proper area for calculating tack rate. This measurement can be taken in many different ways such as 

Application Rate. Tack coat application should result in a thin, uniform coating of tack coat material covering approximately 90 percent of the pavement surface (  Surface King Tack & Prime Coat Applications With Asphalt Emulsions Deleting prime would lessen the amount of liquid asphalt contractors must handle,  Prime coat typically is application of low viscosity Bitumen over a granular base, preparing it for laying an asphalt mixture on it. A prime coat performs several  Precoating. AC-5, AC-10, PG 64-22, SS-1, SS-1H, CSS-1, CSS-1H.
