Road Construction Service

Field Dry Density

Field Dry Density Test or Field Density test is a crucial component of road construction service to determine the compaction quality of the soil, ensuring the specific requirements for the construction project.

There are several methods of Field Density Testing

Sand cone method
Nuclear density Gauge
Rubber Ballon method

Among the various methods available for determining soil density, the sand cone method has emerged as a popular choice in Bangladesh, primarily because of its simplicity and cost-effectiveness.

California Bearing Ratio (CBR Test)

The California Bearing Ratio (CBR) Test is a crucial test in road construction, used to assess the strength and suitability of subgrade soil and subbase materials for pavement design. It provides valuable insights into the load-bearing capacity of these materials, helping engineers determine the appropriate pavement thickness and design.

Utilizing the correct methods and instruments ensures accurate results, critical for determining pavement thickness and overall structural integrity, leading to safer and more durable roadways.

Dynamic Cone Penetration (DCP Test)

Another widely performed test in soil investigation, road construction, pavement design, or evaluation of existing pavements soil bearing capacity is the dynamic cone penetration test.

For its non-distractive method testing process and cost-effective performance, it is widely used in Bangladesh.

The purpose of this test method is to provide a quick assessment of soil bearing capacity and uniformity, allowing engineers to make informed decisions during construction.
