NEW FDR GUIDE RELEASED, FEATURED IN CCT'S STABILIZATION/RCC SEMINARS

7/7/2017

The National Concrete Pavement Technology Center (CP Tech Center) at Iowa State University has recently published a comprehensive "Guide to Full-Depth Reclamation (FDR) with Cement."  This 90-page manual was developed in cooperation with the Portland Cement Association and many product experts from around the country, including CCT's own Matthew Singel.  It will serve as a centerpiece in CCT's just-announced one-day seminar series "Best Practices for Cement Stabilization and Roller-Compacted Concrete Pavements," to be held at seven Texas locations between August and December, 2017.

FDR is often the lowest-cost method of recycling failed asphalt pavements into highly durable bases.  It is an in-place operation that pulverizes the existing surface and base, then adds a small amount of cement to provide a fast-curing and long-lasting base that stands up to heavy trucks and saturated conditions.  Construction is fast, often completed in one day, so light traffic can be applied afterwards; and the need to excavate huge amounts of old material and replace it with new base material--and the associated heavy truck traffic--is avoided.

The guide provides not only an introduction to FDR with cement, but it also comprehensively covers key topics:
  • Properties and materials
  • Project evaluation (when is FDR appropriate?)
  • Structural design
  • Mix design
  • Construction
  • Inspection and testing
  • Long-term performance
The guide is geared for design, testing and construction professionals, so that they can properly utilize this highly economical and durable asphalt pavement recycling method.  

If you are interested in being trained in this technique, using the new guide, please consider attending one of the CCT's 7 upcoming seminars.  To find out more about FDR, and download the guide, visit the CP Tech Center's website.

Intelligent Compaction in Cement-Based Pavement Applications

12/31/2016

1 Comment

 
By: Matthew W. Singel
​Intelligent compaction (IC) refers to the continuous, real-time monitoring of a roller’s effectiveness in achieving a specified density, stiffness, etc.  This continuous feedback approach to pavement construction has tremendous implications in the realm of quality assurance....

Dry Summer = Subgrade Shrinkage, Asphalt Cracking

12/31/2016

0 Comments

 
By: Matthew W. Singel
​Extended periods of high temperatures and low rainfall wreak havoc on agriculture, drinking water supply and lake access for recreation.  For civil engineers and public works professionals, these conditions can create an imbalance in the subgrade moisture content, leaving soils under the center of the road at a higher moisture level than the edges, which dry out more quickly.  This is most prevalent on roads with deep drainage ditches (i.e. subgrades with exposed sides).  In the presence of expansive clay soils, deep longitudinal cracking often occurs near the road edge.

    PURPOSE

    The Cementx Pavement Blog seeks to make pavement owners, engineers and contractors smarter about selecting, designing, constructing and maintaining pavements. New blog postings began February 1, 2017; however, we carried over pavement-related blog postings from our older blog, the "Texas Cement and Concrete Blog," which ran until December 2016.
