CrackMaster TRM
Designed for use with oil-jacketed kettles. Contains a high crumb rubber content. Ideal for use on roads and highways.
Sizes Available
50 lb. box with two 25 lb. cubes per box.
Coverage
Use the following chart as a guideline for estimating material requirements (based upon pounds of material needed for 100 feet of cracks):
| Crack Width | Depth | lbs. / 100 ft |
| 3/8″ | 3/8″ | 6.9 lbs. |
| 1/2″ | 1/2″ | 12.3 lbs. |
| 3/4″ | 3/4″ | 27.8 lbs. |
NOTE: The above coverage rates are only a guideline. Actual material usage may vary due to width of application and thickness of material above pavement surfaces.
Description
CrackMaster TRM is a hot pour crack and joint sealant for portland cement and asphaltic pavements. As an economical and effective preventative maintenance treatment, CrackMaster TRM prolongs pavement life by sealing cracks and joints from water penetration, which cause base failure and potholes. This is a high viscosity, non self-leveling material with a crumb rubber content of 18% minimum based on asphaltic components or 13% minimum by overall weight. CrackMaster TRM forms a long-lasting seal which resists tracking in warm temperatures and remains flexible in cold temperatures.
Uses
CrackMaster TRM is recommended for sealing cracks and joints in portland cement, asphaltic pavements, and parking lots. It is designed to seal expansion and contraction joints, longitudinal and transverse cracks, joints between concrete and asphaltic shoulders, and random cracks.
Mixing Procedures
Use material as supplied. Do not blend with other materials. After CrackMaster TRM is melted it should be agitated or recirculated.
Application
Apply heated CrackMaster TRM using either a pump and wand system or a pour pot. For best results the sealant depth to width ratio should not exceed 2 to 1 (i.e. 2-inches deep to 1-inch wide). The cooled sealant height should not exceed 1/8″ above surrounding pavement. Using a sealing shoe or squeegee, band the material 2 to 3 inches wide over the crack.
Important
Protective apparel is recommended with application of CrackMaster TRM. The extremely hot material will cause severe burns on contact with skin. OSHA Safety Regulations require workers to wear the following types of safety attire (see current OSHA/Safety Regulations for additional information): Hard hat with face shield; long sleeved shirt buttoned at the wrist; heat resistant gloves; long, cuffless pants; and safety toed work boots. Make certain all area around melter is clear of all debris and flammable materials. Avoid breathing vapors. Use with adequate ventilation.
Clean Up
Wash tools in water before material dries.
