What is Hot Mix Asphalt Pavement?
Asphalt pavement refers to any paved road surfaced with asphalt. Hot Mix Asphalt (HMA) is a combination of approximately 95% stone, sand, or gravel bound together by asphalt cement, a product of crude oil. Asphalt cement is heated aggregate, combined, and mixed with the aggregate at an HMA facility. The resulting Hot Mix Asphalt is loaded into trucks for transport to the paving site. The trucks dump the Hot Mix Asphalt into hoppers located at the front of paving machines. The asphalt is placed, and then compacted using a heavy roller, which is driven over the asphalt. Traffic is generally permitted on the pavement as soon as the pavement has cooled.
Combining the well-documented smoothness and safety advantages of asphalt with an advanced, multi-layer pavement design process... Perpetual Pavement combines the well-documented smoothness and safety advantages of asphalt with an advanced, multi-layer pavement design process, that with routine maintenance, extends the useful life of a roadway to half a century or more. Pavements designed and constructed in accordance with the Perpetual Pavement concept will last, and last, and last.
HMA Ultra-Thin offers a simple, cost effective way to maintain roads and streets, as it protects your investment in them. A hot mix asphalt treatment designed specifically for thin lift (3/4 inch) placement, HMA Ultra-Thin was developed for structurally sound pavements that are showing signs of aging, oxidation or minor surface disintegration. You end up with a stronger, more beautiful pavement that improves the ride quality for drivers and reduces traffic noise for the community.
Rubblization is a proven construction technique that turns a deteriorated concrete road into the base for a smooth, safe, quiet, durable pavement constructed of Hot Mix Asphalt (HMA). It minimizes delays for motorists and allows for construction during "off-peak" hours. Rubblization with an asphalt overlay is a very cost effective rehabilitation method.
Life Cycle Cost
For the initial construction and over the long haul, asphalt pavement saves money on construction and maintenance. That’s the conclusion of highway engineers and departments of transportation across the country. The “life-cycle costs”—money spent on road construction and maintenance over its lifetime—are significantly lower with Hot Mix Asphalt (HMA) than with concrete.
Thin Asphalt Overlays
Your Cost-Effective Solution
Thin HMA overlays, 1 ½" or less, are the cost effective solution for pavement preservation primarily because of their ability to:
Motorists care about smooth pavements. Asphalt will consistently give the driving public the smooth, quiet ride they have come to expect. Smooth pavements save fuel. Smooth pavements save vehicle operating costs. Smooth pavements last longer. Asphalt pavements are smoother and are easier to keep smoother than concrete pavements.
The national survey found that drivers prefer well-maintained, safe, and smooth roadways; moreover they understand these qualities require periodic maintenance and financial investment.
