There is no doubt that highways, roads, and airfields are crucial for modern transportation, as they literally lay the ground for extensive movement. However, during road construction, the ground is not always guaranteed to be viable; this is dependent on the soil profile, so there is a need to comprehend the properties of soil at the sub-grade level. AASHTO M145 / ASTM D3282 -15:  (Standard Practice for Classification of Soils and Soil-Aggregate Mixtures for Highway Construction Purposes) classifies soils from any geographic location into groups.

An "Inspection and Test Plan" (ITP) might also be called a "Quality Inspection Plan (QTP)". Inspection and Test Plans set out critical control points or ' hold points ' at various stages within a process. Each control point is a scheduled inspection or verification activity, where you will make sure that things are progressing as they should be. Inspection and Test Plans (ITP) are often used as a way to satisfy the requirements of the ISO 9001:2015 standard related to control of production and service provision. Did yo
