Asphalt paving is more flexible and suitable for temperature fluctuations, typically lasting 15-20 years. Cement paving is more rigid and durable, ideal for heavy traffic, and can last 30 years or more.
Asphalt requires regular sealing and may need resurfacing, while cement needs less frequent maintenance but may require sealing. Both types of pavements can be recycled and used in new construction projects.
Asphalt can soften in extreme heat, while cement can crack in cold weather. Common issues include cracking, potholes, and rutting for asphalt, and scaling and spalling for cement.
The base layer provides a stable foundation, preventing deformation or cracking. Asphalt cures within a few hours to several days, while cement takes around 7 to 28 days.
Consider factors such as budget, climate, intended use, and aesthetics. Asphalt can be colored with sealants, while cement can be colored with pigments or stains.
Seal coating is a protective layer for asphalt against oxidation and spills, while slurry sealing enhances durability and appearance. Seal coating is recommended every 2-4 years, and slurry sealing every 3-5 years.
Striping involves applying markings to guide traffic, while ADA striping ensures accessibility. They enhance safety, traffic flow, and compliance with legal requirements.
Application requires temperatures above 50°F and dry conditions. For striping, water-based acrylics, solvent-based alkyds, and thermoplastic are commonly used.
Seal coating is applied after the asphalt has cured, while slurry sealing can be applied to new and aged pavements. Drying times vary, with seal coating taking 24-48 hours and slurry sealing a few hours to 24 hours.
Wear protective gear, ensure proper ventilation, and follow procedures for material handling and curing. Repairs involve patching or resurfacing for asphalt and filling cracks or grinding surfaces for cement.
