When a panel of industry quality control experts was asked what automated measurements would add value to asphalt production, "moisture content on belts/in bins" and "automatic gradation and

Trinidad Lake Asphalt (TLA) is a natural asphalt that was used in the first asphalt pavements built in the U.S. more than 100 years ago. TLA is still used today in high-stress applications around the world, and it is now produced in a pelletized form to facilitate shipping and introduc-tion into modern asphalt plants.

Moisture damage in hot mix asphalt pavements is a periodic but persistent problem nowadays, even though laboratory testing is performed to identify different moisture-susceptible mixtures. In this study, a Hamburg Wheel Tracking device (HWTD) was used for rutting tests which were conducted on control and a high percentage of recycled asphalt pavement (RAP), i.e., 30%, 50% and 100% of

Polymer-modified asphalt cements (PMA) have been used for many years to reduce the amount of severity of distress and extend the service life of hot mix asphalt pavements and overlays. McAsphalt offers the industry's most advanced line of PMA, designed to maximize the beneficial effects of the binder on permanent deformation, fatigue and low

A non-nuclear density gauge (NNDG) was evaluated as part of an asphalt runway resurfacing project. The repeatability of the NNDG was found to be high but asphalt temperature and surface moisture had a significant effect on the reliability of NNDG inferred asphalt density. It was also found that a single NNDG inferred density, located immediately over the core location, provided greater

A change in the asphalt cement source will require testing for Moisture Susceptibility in accordance with DOTD TR 317 and either AASHTO T324 or DOTD TR 322. 501.04 LOT SIZES. A lot is a segment of continuous production of asphalt concrete mixture from the same JMF produced for the Department at a specific plant, delivered to a specific DOTD

moisture-induced damage characteristics, since adhesive bonding potential between aggregate and asphalt will be critically controlled by physical-chemical reactions of mix components (i.e., aggregate and asphalt) with anti-stripping agents treated in the mix.

The fact is, asphalt pavements have a very small car-bon footprint compared to other pavement materials. 3 In addition, the U.S. Department of Energy recognizes asphalt as a top material for sequestering carbon.4 Not All Asphalt Is the Same When examining regulations and health information regarding asphalt, it is important to note that the

25% or less of their production. In only one refinery did asphalt represent more than 75 % of production. Many refineries produce no asphalt whatsoever, consuming all residua through catalytic treatment or coking. The shift to heavier crude oil feedstocks since the 1970's has also had an effect on refinery production of asphalt.

A single ounce of SoKleen eliminates dust from 50 pounds of sand. It remains active not only on sand but also on clay, gravel, limestone, mixed aggregates and most native soils, regardless of the weather. It prevents the creation of additional harmful dust, and is ideal

From the environmental conservation perspective, warm mix asphalt is more preferable compared to hot mix asphalt. This is because warm mix asphalt can be produced and paved in the temperature range 20–40°C lower than its equivalent hot mix asphalt. In terms of cost-effectiveness, warm mix asphalt can significantly improve the mixture workability at a lower temperature and thus
