We recently were asked a question about NMAS mixes and rutting. We reached out to a guest for an “Asphalt Man” answer. Here is the question and the answer
Question: Should we be concerned about rutting using thin overlays and smaller sized aggregates?
Answer: The best information on rutting of thin overlays or mixes with smaller aggregate size comes from the NCAT test track. The following are excerpts from NCAT Report 13-05, THIN HMA OVERLAYS FOR PAVEMENT PRESERVATION AND LOW VOLUME ASPHALT ROADS. (Click here to see the entire answer)
On Thursday August 20, CAPA coordinated a open house for the placement of mastic for wide crack repair. The event was hosted by South Suburban Parks and Recreation District and the demo was performed by Vance brothers. The demonstration was held at the Goodson Recreation Center on South University Boulevard.
The open house had a lot of interest with approximately 100 attendees. The demonstration provided the guidance on the use of mastic to fill wide cracks (more than 2 inches wide).
Background: The Colorado Chapter of the American Public Works Association and the Colorado Asphalt Pavement Association (CAPA) established a scholarship program to expand on the asphalt education opportunities persons who are involved in the design, testing quality control, production, management, supervision, or direction of capital and maintenance projects. Funding has been obtained through both organizations to support asphalt pavement related training and educational opportunities for personnel employed by public work agencies in Colorado, contractors and consultants.
Program: The primary training opportunity that is being presented is the “Short Course in Asphalt Technology” taught at the National Center for Asphalt Technology (NCAT) at Auburn University, Auburn, Alabama. The purpose of this one-week intensive course is to provide a general understanding of all phases of HMA technology. Upon completion, the participant will be able to make knowledgeable decisions related to HMA pavements and communicate effectively with asphalt specialists and contractors when the need arises. The course will be held the week of February 22, 2016.
