LMCQS for Chip Seal is a cationic quick set asphalt emulsion designed for use in chip seals on the Hawaiian Islands. It is designed to set quickly, while allowing for additional stability during shipping and more workability for the contractor. Conforms to AASHTO M208 and ASTM D2397 requirements for CRS-2, except for penetration and demulsibility. Tested in accordance with ASTM D140, ASTM D244, and AASHTO T59. Contains select polymers (2-3% based on mix design) to provide superior adhesion and cohesion with aggregate.
USES
LMCQS for Chip Seal is designed as an asphalt emulsion to be applied by spray distributor truck.
COVERAGE
Application rate is 0.25 – 0.50 gal/yd² depending on the chip aggregate size and mix design.
FEATURES OF CHIP SEALS
- Low cost pavement maintenance method
- Protects asphalt surface from oxidation, water-intrusion, and raveling
- Corrects surface cracking and minor surface irregularities
- Improves skid resistance
- Versatile application – can be used in low volume residential streets or high traffic roads
- Minimal change in curb height
- Non-Hazardous
SURFACE PREPARATION
Pavement surface must be swept clean and dry. Surface repairs should be made with suitable hot or cold mix asphalt, such as PatchMaster. Cracks should be filled with SealMaster Hot Applied crack fillers. Treat all grease, oil, and gasoline stains with SealMaster® Petro Seal or Prep Seal. To improve chip adhesion, a fog seal of the same emulsion type may be applied prior to chip seal application.
APPLICATION
Apply LMCQS for Chip Seal with a spray distributor truck according to design application rate. Before emulsion sets, apply chip aggregate using a self-propelled or tow behind aggregate spreader such as the R-1 Aggregate Chip Spreader. Use a pneumatic tired roller for compaction. An aggregate embedment depth of 70% is ideal. A sweeper is recommended after compaction. To minimize chip loss, a fog seal may be applied after sweeping.
MIXING PROCEDURES
Circulation of product is recommended after an extended period of storage. Avoid repeated pumping.
IMPORTANT
Do not apply when rain is imminent or forecast. Do not dilute. Note: Chip Seals do not improve the structural strength of pavements.
CLEAN UP
Wash tools in water before material dries. After material has dried, clean up with TarBuster or other asphalt remover.
