About this file
This document is a Technical Data Sheet for the CrackMaster Mastic T2-CPT, a hot-applied pavement repair product manufactured by SealMaster, a pavement products and equipment company. The technical specification sheet provides detailed information about a specialized mastic material designed for repairing distressed asphalt and concrete surfaces, meeting ASTM D 8260 Types 1 & 2 standards.
The product is a black, asphalt-based, polymer-modified mastic designed for sealing wide cracks and joints, repairing potholes, utility cuts, manhole covers, spalls, and other pavement defects. It is characterized by excellent adhesion, rapid melting, and the ability to withstand heavy loads, weather, and thermal movement. The mastic is packaged in 30 lb. poly-bags, with each pallet containing 75 boxes or 2,250 pounds of material. Application requires an oil-jacketed kettle with specific temperature controls (375-400°F), and the product can be used on surfaces with temperatures of 40°F or above. Coverage varies based on width and depth, ranging from 39.7 to 317.9 pounds per 100 linear feet, and an optional topping aggregate is available for additional skid resistance.

PRODUCT DESCRIPTION
CrackMaster Mastic T2-CPT is a hot-applied repair mastic comprised of a black, asphalt-based, polymer-modified binder and a select aggregate. This material is self adhesive. CrackMaster Mastic T2-CPT resists cracking, delamination, and spalling. It is a flexible material that can withstand heavy loads, weather, traffic and thermal movement. CrackMaster Mastic T2-CPT provides a high-friction surface to ensure driver safety. Compaction equipment is not necessary with CrackMaster Mastic T2-CPT. This repair system is formulated to provide a feathered edge.

SURFACE PREPARATION
In order for proper adhesion to occur, the surface must be free of moisture, dust, loose aggregate, and other contaminates.
Avoid use in highly-distressed areas that require reconstruction.
The substrate and air temperatures must be 40 °F or above.
Use oil-free compressed air and heat to clean and dry the area immediately prior to application. Heating the pavement will promote bonding between the mastic and pavement surface.
Caution: Do not overheat/oxidize the pavement.

MELTING AND APPLICATION
Melt CrackMaster Mastic T2-CPT using an oil-jacketed kettle designed for mastic materials. The kettle should be equipped with an agitator and temperature control devices for the material and heating oil. Carefully insert small quantities of CrackMaster product and the plastic bag into the melter while the agitator is turned off to avoid splash back. Once material has reached application temperature, apply to freshly prepared area.
CrackMaster Mastic T2-CPT can be applied directly from the melter using an appropriate discharge chute, bucket, or mastic wagon. Immediately following application, the mastic shall be leveled and smoothed using mastic lutes. In deep installations, mastic may be applied in layers, cooling in between. Mastic may be covered with CrackMaster Topping Aggregate for additional skid resistance. CrackMaster Mastic T2-CPT is ready for traffic when it has cooled and solidified.
CrackMaster Topping Aggregate is available in both 1/8 inch size and 1/4 inch size with a maximum abrasion loss of 35% (ASTM C 131).
NOTE: The temperature of the heating oil should not exceed 525 °F. Do not heat material over the maximum heating temperature and do not maintain it at that temperature for prolonged periods of time. This could cause the material to gel in the equipment or fail on the pavement. A significant viscosity increase accompanied by stringiness signals the onset of gelation. If this occurs, immediately remove the material from the melter and dispose.
PACKAGING
CrackMaster mastics are packaged in 30 lb. poly-bags in a high-strength, corrugated box with each pallet containing 75 boxes or 2,250 pounds of mastic. CrackMaster mastics are also available in meltable packaging.
