Constructing long lasting roadways is more than just the quality of the pavement layer—the base layers are just as critical. Texas Department of Transportation and researchers at TTI are looking at ways to accelerate the design procedure for base materials using a rapid mix design method.

We are seeking esteemed advice from all on a couple of technical matters related to the design and durability of flexible pavements:1. **What is the maximum limit of Million Standard Axles (MSA) that can be considered for the design of flexible pavements?** 2. **In the case of flexible pavements, what can be the maximum Vehicle Damage Factor (VDF), and what percentage of vehicles can be considered for this factor?**3. Beyond which msa we should consider providing rigid pavement instead of flexible pavement Industry, academician and researchers guidance on these matters would be highly valuable, particularly in ensuring that the design and implementation of our projects are both technically sound and sustainable.

March 26, 2024, was a tragic day for many in Baltimore, MD, when a container ship collided with the Francis Scott Key Bridge, causing its collapse and resulting in numerous fatalities. Stonewall CEO, Chuck LaVerdiere, P.E., S.E., recently shared his structural engineering expertise with listeners of Chris Edwards' Morning Show on WPTF Radio in Raleigh, NC, to shed light on this devastating event. Listen to the full interview here: https://lnkd.in/eHchx_Aj Container ships are some of the largest manmade structures in existence, and their sheer size can be hard to grasp. To give you an idea, imagine a 100-story skyscraper turned on its side, floating down a river. The Dali, which collided with a support for Baltimore's Key Bridge, is 984 feet long—about the height of the Eiffel Tower and over 100 feet longer than North Carolina's tallest building. A ship like the Dali, traveling at just 9 mph with its container load, can exert millions of pounds of horizontal force upon impact, depending on how quickly the ship slows down. Building a bridge that can withstand or deflect such immense force is extremely challenging and often prohibitively expensive. Therefore, modern bridge designs in cargo shipping lanes focus on using structural engineering to create longer spans, positioning vertical supports at a safer distance from these colossal vessels. #StructuralEngineering #FrancisScottKeyBridgeCollapse #NationalSafetyMonth #StructuralSafety #Infrastructure #EngineeringSolutions #CivilEngineering #BridgeDesign #EngineeringInnovation

Exploring the Elite Frame of Mind of Highway Design Engineers Road design can be subjective and depends on various factors such as functionality, innovation, safety features, and integration with the surrounding environment. For a balanced design, the engineer has to approach the design process from the right frame of mind. During our kick-off meeting, we had a candid conversation on the key design considerations for the geometric design of roads.

Expansion Joints Covers (EJCs) - the silent guardians of building structures and the inconspicuous lines we see across buildings. But what are they and why are they so important? Buildings require EJCs to accommodate for natural movements and changes caused from a number of environmental factors: 1️⃣ Temperature Activity: Allowing materials to gracefully expand and contract with the rhythm of changing temperatures. 2️⃣ Humidity Changes: Safeguarding against the swell and shrink of materials in response to shifts in humidity and moisture levels. 3️⃣ Seismic Activity: Ready for seismic shifts, offering controlled movement during earthquakes for structural resilience. 4️⃣ Differential Settlement: Accommodating the subtle settling disparities to keep things balanced and prevent uneven stress. 5️⃣ Structural Movement: Enabling long-term movements without impacting structural integrity. These joints allow for expansion and contraction of building materials without causing structural damage and play a crucial role in the long-term durability of the structures. Reach out to a member of our team to find out how our EJCs can benefit you, or check out out full range below. https://lnkd.in/gq2iJcrj #constructionspecialties #architecture #buildingdesign #structuralengineering #expansionjoints #seismic

When designing speed change lanes to divert traffic to a property abutting major roads, it imperative to check your design with online maps to ensure that your proposed lanes are in alignment with the main road. Attaching the KML files makes it easy for decision makers to approve your designs. Spot the mistakes. This is a project just for demonstration purposes.
