The Ultimate Guide to Understand Expansion Joints Types

Posted by Randall Turner on Apr 8, 2019 2:00:00 PM

Expansion joints are primarily designed to facilitate the movement in structures caused by temperature induced expansion and contraction.  They also help extend the life of concrete structures by providing some “give” in the movement of the structure.  Expansion joints can be used in parking garages, overpasses, roadways, sidewalks, piping structures and railway tracks.
There are many types of expansion joints. This guide will help you understand the differences, so you can make an informed decision for your next construction project.

The Importance of Temperature Monitoring in Asphalt Paving

Posted by Brock Peterson on Dec 17, 2018 12:30:00 PM

It is well known in the asphalt-paving industry that the correct temperature of a finished asphalt mixture is vital to achieving a high-quality, long-lasting pavement. However, there are other environmental factors that must be taken into consideration, such as

The Importance of Expansion Joints on Concrete Bridge Decks

Posted by Brock Peterson on Jun 12, 2018 9:43:24 AM

Expansion joints are vital to the life of a bridge itself and must be correctly installed and maintained in order to function properly. The two major causes of joint failure are improper installation and insufficient maintenance of the joint. Oftentimes, when dirt, dust or other types of debris build-up in and around these joints (caused by traffic and environmental conditions), the joints lose their ability to expand and contract with the structure, rendering them less effective. When this happens, the reduced flexibility will result in cracking or distortion/crushing of the joint material, compromising the entire bridge’s structural integrity.

Drum vs. Batch Plant: Learn the Differences That Will Make Your Asphalt Mix Just Right

Posted by Brock Peterson on May 10, 2018 10:00:00 AM

Often, preparing an asphalt mixture is compared to baking a cake. A contractor needs to make sure he/she has an accurate recipe and proper ingredients and that he/she blends everything at the correct ratios and “bakes” the mixture to produce a beautiful, homogeneous final product that everyone will be happy with – a blend that will perform as anticipated when properly applied on a roadway.

How A Properly Applied Tack Coat Can Extend The Life Of Your Project

Posted by Brock Peterson on Mar 23, 2018 11:10:00 AM

Tack Coat: The Bond That Promotes Optimal Performance

 A vital but often overlooked part of an asphalt pavement is the bond strength between the layers that make up the finished structure. Tack coat is the main component responsible for ensuring a sufficiently strong bond.

 What is a tack coat?

  • It is an asphalt binder that is spray applied onto a substrate material -- typically cement, asphalt or steel (in the case of orthotropic bridges) -- prior to placing a new asphalt overlay.
  • This thin application of bitumen is the glue that binds the two layers of pavement resulting in a uniform structure.
  • This bonding of the layers creates a structure that behaves as a single unit as opposed to unbound, independent layers.

Waterproofing Membranes: Protecting Vital Components of the Nation’s Bridges

Posted by Brock Peterson on Feb 5, 2018 11:30:00 AM

When looking at our nation’s infrastructure, it is not difficult to see there are many bridges in desperate need of rehabilitation. According to the latest Infrastructure Report Card, the U.S. has 614,387 bridges, almost four in ten of which are 50 years or older and nearing the end of their intended service life. In 2016, nearly 10% of these bridges (56,007) were considered to be structurally deficient. 

When considering the durability of a bridge, there are two main areas thought to be the most vulnerable components:

  • The concrete deck
  • The untreated steel rebar used to provide structural reinforcement

Using Thermoplastic Polymers In Asphalt Mix For Bridge Decks

Posted by David Fricke on Nov 15, 2017 11:13:45 AM

Asphalt has been used on bridge decks for over 100 years with the intent of providing an effective road surface area for traffic and limited water-proofing properties. Historically, standard materials have functioned well without the need for modification but as traffic volumes and loads have increased, demand has necessitated a shift to high- performance surfacing materials.
