Construction Cases
In Sinaloa, Mexico, slurry seals are applied using cationic slow-cracking emulsified asphalt (CSS-1h), which accounts for 7.5%-15% of the aggregate weight, with 0.5%-2% cement as filler to enhance adhesion. Local hard limestone crushed stone is used as the aggregate, with a primary ES-2 grade (4.75-9.5mm) and a sand equivalent of 50% or more. Slurry sealers are applied at a constant speed of 1.5-3 km/h, maintaining a paving thickness of 4-6 mm. This extends the pavement’s service life by 5-7 years.
Usage Scenarios
Slurry seal : With a thickness of 3-6mm, it primarily serves as a waterproofing and sealing layer. It has lower strength and is used for light maintenance.
Micro surfacing : This is an improved slurry seal, using polymer-modified emulsified asphalt. With a thickness of 5-10mm, it offers higher strength and durability, capable of withstanding heavy traffic loads. It is commonly used for preventive maintenance or minor damage repair on highways and arterial roads.
Intelligent Control Technology
Chassis: Dongfeng/Shacman Heavy-duty chassis, 280+ HP, high-altitude turbocharging for 4,500m operation.
Precision Batching System: Twin-shaft forced-action mixer,mixing uniformity >95%. Asphalt pump with precise flow control linked to aggregate belt scale batching error ≤ ±2%.
Intelligent Temp Control & Operation: Engine coolant pre-heat; Emulsified asphalt temp control (40±2°C). 7-inch touchscreen for real-time monitoring (aggregate moisture, asphalt ratio) & construction data backup.
Capacity and Efficiency
Large-Capacity: Water tank & emulsified asphalt tank: 3-4 m³ each, Aggregate hopper capacity: 10-12 m³ Reduces downtime for refilling, ensuring sustained material supply for long-duration operations.
High-Efficiency Mixing System: Twin-shaft forced-action mixer (300-500 RPM);Mixing time 10-15 seconds for uniform blend of aggregates, asphalt, and water Prevents material segregation, ensuring consistent paving quality.
Hydraulic Telescopic Spreading Box: Continuous width adjustment during operation (no pause required) Enhances adaptability to varying road widths, maximizing efficiency.
Safety & Environmental Protection
Emergency Shutdown: Emergency stop buttons in operator cabin & paving zone instantly cut power.
Critical Component Protection: Guardrails/covers on mixer & drive systems.Audible-visual alarms along spreading trough edges.
Waste Recycling: Sealed tanks/containers for asphalt & additives. Anti-leak valves + trays prevent soil contamination. Closed-loop water reuse: Cleaning wastewater → Settled/filtered → Recycled for mixing → Minimizes discharge.
