While widely applying long-life pavement with a combined base, research on the technology of full-depth long-life asphalt pavement has been conducted to save …
Extending the service life of asphalt pavements . Long service life is one of the primary drivers of pavement sustainability. Asphalt pavements with longer design life offer the opportunity to reduce life-cycle costs, user delays and environmental impacts compared to a standard 20-year pavement design.
Concrete Construction Equipment & Tools; ... study prepared by consulting firm Applied Research Associates Inc. concludes that concrete pavement has a lower life-cycle cost than asphalt. Methodology for the Development of Equivalent Pavement Design Matrix for Municipal Roadways compares both the long- and short-term costs of …
Micro surfacing is a surface treatment designed to extend the life of asphalt pavements in good condition by providing skid resistance, restricting moisture intrusion, protecting the structure from further oxidation and raveling, and restoring a uniform black appearance.
To accomplish these objectives, three long-life pavements were designed and constructed: one on Interstate 5 near Red Bluff, one on Interstate 5 near Weed, and one on Interstate …
Milling is the process of removing the top 1.5 to 2 inches of asphalt before resurfacing, which adds a new 1.5-inch layer of asphalt on top of the lot. This extends the life of the parking lot by about 15 years. Since this is a long-term investment, you can list it as a capital expense. Replacing concrete also counts as a capital expense.
California's long-life asphalt pavement design is a perpetual pavement design that aims to produce a pavement that lasts 40 years or longer with minimal maintenance. A recent project on I-5 near Sacramento put this …
This paper describes the construction and pavement properties after seven years in porous asphalt with long life in Kyoto Jukan Expressway, comparing with conventional methods. It was constructed in 1998 in accordance with various kinds of specifications (Kyoto Specifications), regarding modified binder, aggregate, asphalt …

Long-life asphalt pavements offer several advantages over conventional pavements, including lower life-cycle cost, lower user-delay costs, reduced …
All four manufacturers of asphalt milling machines remaining in North America (Astec's Roadtec, , , and Wirtgen) have made it easier for users to control milling depth by accepting the technology of third-party machine control systems.. Similar to systems for earthmoving equipment, these GPS- and software-driven …
Long-lasting asphalt starts with a well-prepared sublayer. The type of soil and how well it freezes and thaws can make a difference in how long the asphalt lasts without getting …
Perform a walk-around on the equipment with the operator and related work crew: in a paving operation, the number of ground personnel can outnumber the equipment operators, and they need to return home safely, too.
The in-place density of asphalt pavements is a key indicator of construction quality, durability, and long-term performance. Differential thermal readings—also ...
Long Life Asphalt Pavement (LLAP) is a relatively new methodology that has formed from historical theories regarding limiting strain criterions in the base layer of deep lift asphalt pavements.
