History of Asphalt

Laura Ingalls Wilder, author of the beloved Little House on the Prairie, tells of her first encounter with an asphalt pavement. She was on a wagon journey with her parents in 1894 that took them through Topeka. “In the very midst of the city, the ground was covered by some dark stuff that silenced all […]

What is Full Depth Reclamation?

Full Depth Reclamation (FDR) is a pavement rehabilitation technique in which the full flexible pavement section and a predetermined portion of the underlying materials are uniformly crushed, pulverized or blended, resulting in a stabilized base course; further stabilization may be obtained through the use of available additives. (ARRA) All pavement structures, with the passage of […]

Pavement Selection Check-List

Asphalt Pavement Options! In making a decision concerning the type of pavement to use on a roadway, an agency is obligated to get the best value for the taxpayers. It is up to contractors to provide the pavement that gives the best possible performance at the lowest possible price. Thus, pavement type selection should be […]

Final Considerations for Pavement Selection

There are considerations beyond those discussed above that may be used in determining the type of pavement appropriate for a given situation. It is important to review these in order to develop a holistic justification for pavement type selection decisions. Sustainability It is becoming increasingly important to consider the environmental and economic impacts of pavement […]

Asphalt is America’s Most Recycled Material

According to the 1993 AASHTO Guide, the option of recycling the existing pavement or material from other sources may be a reason to select a particular type of pavement. Future recycling opportunities may also factor into the decision. ASPHALT IS AMERICA’S MOST RECYCLED MATERIAL Asphalt is unique in composite construction materials in that when it […]

Construction Considerations for Asphalt

The 1993 AASHTO Guide states that the option of staged construction may dictate the type of pavement chosen in a given situation. Other factors such as speed of construction, access to businesses, maintenance of traffic during construction, safety, ease of placement, accommodation of future widening, and timing of construction during the year are also important […]

Asphalt in Different Types of Weather

AASHTO discusses the effects of weather on both the subgrade and the wearing course of the pavement. In the new AASHTO M-E PDG, these are referred to as environmental considerations. Precipitation in the form of snow, ice, and rainfall affects the strength of soils on a seasonal basis. Likewise, moisture and temperature, in terms of […]

Asphalt Offers Flexibility in Construction, Maintenance, and Rehabilitation

One of asphalt’s primary advantages is that it allows for a number of construction scenarios. Staged construction allows a pavement structure to be built up over time, meaning that expenditures for a road take place gradually when total funding may not be available all in one year, or if it is anticipated that traffic will […]

Asphalt Pavements Can Handle Heavy Loads

Asphalt pavements have demonstrated outstanding performance across the spectrum of traffic loadings and conditions. Asphalt is by far the most popular pavement material for low- and medium-traffic roadways, and has proven itself over time under heavy truck traffic in urban and rural settings. Even under 4heavy, static, and channelized loadings such as those at port […]
