Generic machines often struggle with temperature consistency and fuel efficiency. Our 2026 upgraded TDZ-500 Trailer Mounted Asphalt Crack Sealer is engineered for extreme durability and precision.
Key Technical Specifications:
· Heating System: Dual-stage diesel burner with PID Temperature Control.
o Benefit: Maintains sealant temperature within ±5°C of the target (usually 190°C-200°C), preventing material burning (which causes brittleness) or under-heating (which causes poor adhesion).
· Agitation Mechanism: Hydraulic motor-driven stirrer.
o Benefit: Ensures homogeneous heating of the rubberized asphalt, eliminating cold spots and ensuring consistent flow viscosity.
· Capacity & Efficiency:
o Tank Volume: 500 Liters.
o Heating Time: Full load from cold to operating temp in 45-50 minutes.
o Fuel Consumption: Optimized insulation reduces diesel usage by 15% compared to 2024 models.
· Application Precision: Equipped with a pressure-regulated hose reel and ergonomic applicator wand with adjustable flow control valve.
o Result: Creates a perfect "band-aid" seal shape (over-band) that bridges the crack effectively.
Not all tapes are created equal. Our High-Strength Bitumen Tape utilizes a modified polymer formula designed for diverse climates.
Performance Data Sheet:
Parameter | Test Standard | Our Product Value | Industry Average |
Softening Point | ASTM D36 | ≥ 95°C | 80°C |
Penetration (25°C) | ASTM D5 | 40-60 (0.1mm) | 70-90 (0.1mm) |
Low Temp Flexibility | -20°C Bend Test | No Cracking | Cracks at -10°C |
Shear Adhesion | ASTM D1000 | > 24 N/25mm | 15 N/25mm |
Waterproof Rating | Immersion Test | 100% Waterproof after 7 days | Varies |
Why This Matters for Your Project:
1. Summer Stability: With a softening point of 95°C, our tape won't bleed or become tacky even on hot summer roads (up to 70°C surface temp), preventing tire pickup.
2. Winter Flexibility: The polymer modification allows the tape to stretch up to 40% without tearing, accommodating thermal expansion and contraction of the asphalt pavement in freezing winters.
3. Instant Bond: The aggressive rubberized adhesive bonds immediately to clean asphalt, creating a watertight seal that stops sub-base erosion instantly.
