The Best by testWhat is Tip Top Tack Coat?
Tip Top Tack Coat is high-quality asphalt emulsion tack coat for pavement bonding applications. Our Tack Coat is a specially-designed high quality undiluted product for ensuring a uniform and strong bond between layers of asphalt in road construction and for maintenance purposes.
"The Best By Test"
The principal source of asphalt tack coat binders is from the refining of crude oil and is a byproduct from the oil refineries. Our tack coat is “The Best By Test.” We do not skimp on or dilute the right materials in the production process. Tip Top Tack Coat meets and/or exceeds all state and federal specifications for asphalt tack coat emulsions. Tip Top Tack is an RS-1 asphalt emulsion, which means it is “rapid set” and has a “low viscosity.” Being a rapid set emulsion, our tack coat contains a maximum of 45 percent water and emulsive additives, so it is not meant to be diluted with water. Our rapid-setting emulsion typically has a higher viscosity than slow-setting emulsions.
Description of Tack Coat
Tack coat is a brownish-black emulsion of asphalt that is applied to the prepared, existing surface prior to placing new hot mix asphalt. The tack coat bonds to the original layer and then the new hot asphalt, when it is placed, bonds to the layer of emulsion creating a monolithic pavement structure. The ability to make formed of a single large section of asphalt is what holds the pavement layers together so it will not slip with traffic on in. Creating this bond also helps prevent water intrusion that result in potholes, delaminating or frost breaking up the newly-placed pavement layer. After putting down the tack and exposure to the air Tack coat ”breaks” or dries in 10 to 15 minutes and is incredibly sticky when it does, so great care must be taken not to get in on vehicles or clothing.
Typical Tack Coat Applications
Tack coat is applied to existing pavement, including planed asphalt surfaces. It is used for bonding between hot mix asphalt layers to prevent slippage and on vertical surfaces such as construction joints, curbs and trench cuts for both bonding and waterproofing. The application rate changes on vertical surfaces where you are looking for a residual tack coat rate that will thoroughly coat the vertical face without running off. There is also a need to create a seal between the old and new asphalt.
