Concrete Pavement Construction Process The construction of concrete pavement involves sequential construction of subgrade, sub-base/ base and the concrete slab. These are discussed in the following. Subgrade preparation Subgrade preparation involves cleaning, earthwork (excavation or filling of soil, replacement of weak soil, soil stabilization etc.) and compaction. Where the...

Pile Integrity Testing (PIT), also known as low-strain impact integrity testing, is a non-destructive method used to evaluate the continuity, consistency and approximate physical dimensions of deep foundation elements. The test is applicable to driven concrete piles, cast-in-place piles, drilled shafts, augered piles and other deep foundation members that can respond to a low...

Concrete is normally selected for its strength, durability and versatility. However, some applications require another important property: high mass within a limited volume. This is where high density concrete, also known as heavyweight concrete, becomes useful. By replacing conventional aggregates with heavier natural or manufactured materials, concrete with a significantly ...

The compressive strength test is one of the most important quality-control tests for concrete. ASTM C39/C39M covers the determination of compressive strength of molded concrete cylinders and drilled cores having a density greater than 800 kg/m³. The test involves applying a continuously increasing axial compressive load until failure and calculating the strength from the maxi...

Building a new home is one of the biggest financial decisions most people will ever make. While the design, location, and finishes are important, the success of the project often depends on one critical decision: choosing the right new home construction contractor. The wrong contractor can lead to delays, cost overruns, poor workmanship, and stressful ...
