Description
Deery 103GLCA Hot-Applied Crack & Joint Sealant
Caltrans-Compliant Performance for Demanding Pavements
Deery 103GLCA is a hot-applied, single-component crack and joint sealant engineered specifically to meet Caltrans SSP 37-6.02B Type 4 requirements. Formulated with asphalt cement, virgin synthetic polymer, premium rubber, and performance-enhancing modifiers, this solvent-free sealant delivers dependable flexibility and adhesion where a free-flowing material is preferred.
Designed for highways, streets, and aviation pavements, Deery 103GLCA flows easily into longitudinal and transverse joints as well as random cracks, creating a tight seal that blocks water and debris before they can compromise the pavement structure. Once installed, it moves with the pavement through seasonal expansion and contraction instead of pulling away or becoming brittle.
Key benefits at a glance:
Fully compliant with Caltrans SSP 37-6.02B Type 4
Moderate viscosity for excellent crack penetration and clean application
Strong adhesion and flexibility for long-term sealing
Effective moisture and debris barrier in moderate temperature regions
Zero VOC, solvent-free formulation
Think of Deery 103GLCA like a flexible gasket engineered to a strict specification—it seals tightly, flexes under stress, and keeps doing its job year after year.
For agencies and contractors working on specification-driven projects, Deery 103GLCA provides confidence, consistency, and proven pavement protection.
What Is Deery 103GLCA and Where It’s Used
Deery 103GLCA is a hot-applied pavement preservation sealant developed to meet California Department of Transportation SSP 37-6.02B Type 4 specifications. Its moderate viscosity allows it to flow effectively into cracks and joints while maintaining the elasticity needed to handle pavement movement.
This sealant is commonly specified for:
State and municipal highways
Urban and suburban streets
Airport runways and taxiways
Asphalt and concrete pavements requiring Caltrans compliance
Properly installed, Deery 103GLCA forms a durable, waterproof seal that helps prevent moisture infiltration, debris intrusion, and premature pavement failure.
How to Use Deery 103GLCA – Step by Step
Surface preparation
Cracks and joints must be clean and dry before sealing. Remove all dirt, debris, vegetation, and moisture. Pavement temperature must be at least 40 °F at the time of application. In cooler conditions, warming the surface with a Hot Air Lance is recommended.Heating
Heat the sealant in a hot-oil jacketed melter with constant mechanical agitation and a calibrated thermometer to monitor temperature.
Minimum application temperature: 380 °F
Maximum heating temperature: 400 °F
Avoid prolonged heating at or above these temperatures, as overheating can permanently damage the material.
Application
Once minimum application temperature is reached, Deery 103GLCA is ready for immediate use. Place material into clean cracks or prepared reservoirs using:
Hand-held pour pot
Wheeled push bander
Wand applicator
Finishing
Squeegee excess sealant tight to the pavement surface to create a smooth, uniform seal.Reheating
Material may be cooled and reheated if needed, provided prolonged heating is avoided and temperature limits are respected.

Frequently Asked Questions
Is Deery 103GLCA required for Caltrans projects?
Deery 103GLCA is specifically formulated to meet Caltrans SSP 37-6.02B Type 4 and is commonly specified on California roadway projects.
What type of cracks is this best for?
Its moderate viscosity makes it ideal for longitudinal and transverse joints and random cracks where a free-flowing sealant is preferred.
Can it be used outside California?
Yes. While designed for Caltrans compliance, Deery 103GLCA performs well in other regions with moderate high and low pavement temperatures.
Can unused material be reheated?
Yes, provided prolonged heating is avoided and maximum temperature limits are not exceeded.
Why choose a Caltrans-specific sealant?
Specification-driven sealants reduce approval delays, ensure compliance, and provide predictable performance on regulated projects.
Packaging Options
Deery 103GLCA is available in:
30 lb cardboard boxes with quick-melt release film (75 boxes per pallet)
30 lb meltable packaging, sold by the pallet only
Both options are OSHA and GHS compliant, palletized for efficient handling, and suitable for outdoor storage.
For contractors and agencies that need specification compliance without sacrificing workability or long-term performance, Deery 103GLCA delivers reliable, professional-grade crack sealing results.
