Innovations in Hot-Mix Asphalt FHWA-HIF-07-012

This innovation has become a hallmark of the industry and asphalt is America's most recycled material as a result. As the 1970s started to give way to the 1980s, agency concern over asphalt pavement performance led to intensive efforts to improve specifications and mix design processes, and to tailor mixes to specific circumstances.

Trends in asphalt: mix design drives innovation

The latest innovations in asphalt plant automation can be attributed to the demand for more mixes using more types of ingredients that need to be carefully blended together in the process. Asphalt Contractor reports on the latest trends.

The History of Gyratory Compaction Purdue Engineering

to capture the events and rational of those who contributed significantly to the use of gyratory compaction in the design and field management of hot-mix asphalt HMA and discusses the challenges ahead. Throughout the evolution of asphalt mix design; several different types of laboratory compaction devices have been developed.

Optimized Mix Design Approach Asphalt Pavement

Smaller NMAS and lower traffic mixes need more binder • Adjust virgin binder content as a function of RAP and RAS addition to compensate for lack of 100% recycled binder contribution • Conduct mix design compaction at four binder contents Vbe min, Vbe min- 0.50, Vbe min 1.0, Vbe min + 0.50 Optimized Mix Design Approach – Framework

French bituminous mix design versus pavement

The main idea of this paper is verifying the performance of the asphalt mix, for comparisons concerning the preliminary studies and the laboratory tests with asphalt mixes

Road Construction Innovation: Is it Difficult

In the past few years, some modest progress has been made in road conservation and operation techniques. However, the core of the rehabilitation activities has not moved on since the development of asphalt mixes in the early 20th century. Progress in this area is recently linked to management systems generally, pavements and structures.

Improving the Performance of Recycled Materials in

Construction aggregate is typically the coarse sand, gravel and crushed stone in concrete or asphalt mixes. It works to reinforce the overall strength of mixes. But it is limited in its quantities, so replacing it in concrete is a large-scale problem for future construction projects.

Performance Evaluation of Hot Mix Asphalt Concrete

With the depletable nature of asphalt binders and the environmental and social hazards of waste plastic, this paper seeks to determine the effectiveness of using polymeric waste polyethylene to modify asphalt mixes and to optimize the penetration values, softening points, fire points, and flash points to make the asphalt mixes more durable

Reclaimed Asphalt Pavement User Guideline

The Asphalt Institute suggests that when 20 percent or less RAP is used in a mix, no change in asphalt grade is required. However, for mixes with greater than 20 percent RAP, a drop in one grade softer asphalt cement is recommended to compensate for the greater viscosity of the oxidized binder.

Blog | Morgan Pavement Part 3

Other trade names for asphalt mixes included Wilite, Romanite, National Pavement, Imperial, Indurite, and Macasphalt. Many of these patented mixes were successful and technically innovative. The fierce competition among asphalt producers, however, allowed cities to require more stringent requirements for their asphalt roadways.
