Asphalt Plants – Know the facts

Thousands of communities across the country coexist peacefully with asphalt pavement mix plants. These facilities are in urban, suburban, and rural areas, and most of them are known as good neighbors who are engaged with their community and dedicated to sustainable operations. However, there is a lot of misleading and often daunting information about asphalt plants and products. Therefore, it’s important to understand what is fact and what is fiction.

Thinlay Specification Released

Thinlays offer a high value to public and private pavement owners alike. Thinlays are asphalt mixes that can be placed at a thickness between 5⁄8 and one inch. Thinlays for pavement preservation offer economic, engineering, and sustainability benefits. Thinlays were developed for structurally sound pavements that are showing signs of aging, oxidation or minor surface distresses.
Thinlays share many of the benefits seen in overlays and inlays: extended pavement life, smooth ride, a modest improvement in pavement strength, enhanced safety, and responsible use of natural resources through reuse and recycling. Thinlays are versatile, cost beneficial and compatible with asphalt pavements.

The Economic Value of Pavement Overlay Alternatives


The majority of the US highway roadway system has been completed for many years, thus requiring agency resources to be focused on maintaining and rehabilitating existing pavements. Economic analysis of pavements must consider initial costs, design life, maintenance costs over the life of the pavement and salvage value at the end of its life-cycle. This case study examines five pavement rehabilitation methods for asphalt roadways using equivalent 20-year pavement overlay designs in contrast to the 40-year life cycle designs traditionally used for new construction and full-depth reconstruction. These designs will be judged under the scrutiny of the economic value of the pavement from the beginning to the end of the 20-year pavement life-cycle.

About MAPA

porous pavementMinnesota Asphalt Pavement Association (MAPA) was first Incorporated in 1942. MAPA represents about 96 percent of Minnesota’s asphalt industry – approximately 23 asphalt producers along with 9 asphalt non-producers and 100+ associate members who supply materials to the asphalt pavement industry. The association represents members’ interests regarding items involving transportation, the environment, and legislation.
