With the impending summer heat, you may notice that certain concrete surfaces in your driveway or parking lot begin to develop cracks or even buckle, which can be pretty costly.
While Quality Asphalt, serving Sturgeon Bay, cannot control the weather, we can help owners seal and protect their concrete surfaces and driveways to keep them from being affected by the heat and draughts while experiencing distresses like buckling.
This blog post will explain what concrete buckling is, why it happens, and how we can remedy it with joints.
What Causes Pavement Buckling?
Several issues, including the following, cause buckling and yielding of reinforcement in concrete structures:
- The unexpected application of loads such as earthquake stresses, increased occupancy loads, intense wind loads, and so on.
- Buckling and yielding of reinforcement may develop in structures as they age since durability issues, such as corrosion of steel reinforcement, can lower the strength of concrete.
- Road buckling is also caused by a significant increase in air temperature or cement hydration. It is more prevalent on older concrete pavement. Heat causes materials to expand and contract, which is why engineers construct concrete structures with expansion joints to allow the structure to expand and contract without buckling. However, if these expansion joints are filled up with foreign material or if they’re not inserted at all, the concrete structure may buckle as the temperature rises. During the hot summer months, this is common with concrete pavement.
How do Concrete Pavement Joints Help?
The proper placement of joints is critical in preventing random pavement cracking. Concrete pavement joints are meant to serve multiple functions, including the following:
● Crack management
● Load transfer
● Isolation of structures that move or behave differently
● Lane or shoulder delineation
What Impacts Joint Performance?
Many jointed concrete pavement distresses caused by poor joint design, construction, or maintenance. Faulting, pumping, spalling (owing to any of various causes), corner breakdowns, blowups, and mid-panel cracking are examples of these problems (when caused by excessive joint spacing or improper joint construction).
Joint performance is also dependent on the application of acceptable pavement design standards, high-quality construction materials, and proper construction and maintenance processes. One must consider all of these aspects in order to produce pavement joints that will perform satisfactorily over the pavement’s service life.
Quality Asphalt, serving Sturgeon Bay, provides practical and economical asphalt maintenance services that include filling the joints in your driveway to give a uniform surface. With our assistance, your driveway should be ready to endure all types of wear and tear caused by elements such as heavy traffic, harsh weather conditions, and so on.
